As much as both Mitch and Sandra were looking forward to Sandra giving her first-ever blowjob to Mitch the following night, fate conspired against them.  Both of them had a series of emergencies at work which caused Mitch to have to work late the first night after the titfuck, and the following night it was Sandra’s turn to have to work late.  The third night looked like a charm, but just as Sandra was pulling into Mitch’s driveway the text alert notification on his cell phone went off, and when Mitch checked it he was more than a little bit disappointed to see that he had yet another emergency which required his presence at a job site on the other side of town.  It would be hours before he would be done, so he reluctantly sent his little sister home.  As it turned out, he didn’t get home until nearly one o’clock in the morning, so sending her home was the right call.

They both kept their fingers crossed all day during the fourth day, and when quitting time for both of them came around and there were no emergencies to take care of they were both elated.  Just as he got in his car to head home, he got a text message from Sandra.

‘All is good here, headed your way now!’  Mitch smiled as he typed out his reply.

‘Ditto!  See you at the house!’

‘Can’t wait!’ Sandra replied, making Mitch smile again.  He started his car, backed out of his parking spot, and headed for his house.

He had been home just long enough to drop his briefcase and grab a beer out of the refrigerator when the doorbell rang.  He walked over to the door and opened it, and there was Sandra just as he expected.  She was positively beaming, her eyes sparkling, grinning from ear to ear as she stood there with her hands clasped down in front of her.  And as usual she was dressed to kill, wearing a skin-tight black short sleeved dress with a very low, scooped neckline that showed a more than generous amount of cleavage.  The dress stopped at mid-thigh, showing off her nylon-clad legs.  A pair of shiny black spiked shoes completed her outfit, and Mitch had no doubt that every man’s dick in the office had been hard that day once they got a look at her.

His little sister was the sexiest, most beautiful woman he’d ever seen, and he wanted her so badly it hurt.

“Hi, big brother!” she said cheerfully, grinning from ear to ear.

“Hi, Sandra,” he said, returning her smile.  He stepped aside so she could come in, closing the door behind her.  He turned around to follow her into the house and almost ran into her since she had stopped less than a foot away, and before he could react she put her arms around his neck, pulled his head down and kissed him, long and deep.  She molded her body to his, and he could feel the firm mounds of her huge breasts pressing into him.  He put his arms around her slim body and pulled her close, and she could feel his cock shifting against her as it began to grow in his pants.  Then she slipped her tongue into his mouth to find and dance with his, and by the time she finally broke off the kiss they were both nearly breathless.

“I’ve wanted to do that for the past four days,” she said, her voice a whisper as she looked up into her brother’s eyes.

“I’m glad you did,” Mitch replied, meaning it.

“I also figured that would be a good way to get the evening started!” she said lightly, smiling at him, her arms still around his neck and her body pressed up against her.  “And from what I can tell so far, you’re ready to get things going too,” she said, pushing her body against the growing bulge that was his cock.

“Can you blame me?” he replied, returning her smile.  “You show up at my door in a dress that fits you like a second skin and shows more cleavage than the Grand Canyon, then slap a kiss on me and nearly choke me to death with your tongue, all the while pushing those big fun bags of yours against me – what would you expect?  Applause?” he said, playing with her and making her giggle.

“Why don’t we go into the living room so I can suck that big cock of yours, big brother?” she asked, her voice low and sultry.

“Good idea,” he replied.  She put her arm in his and together they walked into the living room, stopping in front of the couch.  She turned and kissed him again, just as passionately as before, but this time running her hand down his body between them to find the growing bulge of his cock.  She rubbed her hand over it and then gripped it through his pants, squeezing it firmly as she sucked on his tongue.  He slid his hands down her body and gripped her ass in both hands, squeezing the firm, rounded globes hard as he pulled her closer to him.  She moaned at his touch and gripped his cock harder.  After a few more very pleasurable moments she broke off the kiss, stepping back from him and holding both of his hands in hers.  She was breathing hard, her big breasts bobbing in her dress as she panted for breath, and Mitch could see that her nipples were hard as well.

“Wow!” she gasped, smiling at him. 

“Wow, indeed,” Mitch replied, returning her smile.

“Now take off your pants and sit down,” she said, releasing his hands and taking a step back.  “The shoes, too.”  Mitch did as he was told, his fully erect cock bouncing and swaying in front of him.  She stood there and watched, her eyes locked onto his hard cock, biting her bottom lip as she watched it bobbing around as he moved.  When he sat down on the couch she stepped in front of him, pushing his feet apart with hers until she had enough room to move around.  Then, looking him in the eyes and still biting her bottom lip, she slid the dress down her shoulders and pulled her arms out of the short sleeves, then pushed it down over her big tits and down her body, slipping out of it and never breaking eye contact with him as she did.  She dropped the dress to the floor and stepped out of it, kicking it to the side before standing in front of him, hands hanging down at her sides as she looked down at him.

She was wearing a leopard print bra and matching thong panties, with the cups of the bra barely able to contain her massive tits.  Smiling as she looked him in the eyes she reached up for the clasp in the front of the bra between the two cups with both hands, unfastening it and then pulling the cups away, revealing her huge, firm tits to him again.  She slipped out of the bra and tossed it aside to land with the dress, then slid her hands under her big breasts and lifted them up, squeezing them and tugging on her nipples, looking him in the eyes the entire time.

“I thought you might want to see my big tits again before I got started sucking your cock,” she said, smiling down at him.

‘Holy shit, I wanna fuck her so bad!’ Mitch thought to himself as he watched his sister play with her tits. 

She was doing this to excite and arouse him, and it was working.  When she took her eyes from his and looked down at his dick, she saw a clear drop of precum forming at the tip.  A big smile broke out on her face, and without a word she knelt down in front of him, moving in close and grabbing his cock with her hand.  She pulled it towards her and without thinking lowered her mouth down to the tip, clamping her lips on the tip and sucking the precum from him.  Then she looked up at him and smiled, slowly pumping his cock in her hand.

“Sorry, big brother, I didn’t mean to get ahead of myself!” she said sheepishly, her hand slowly pumping his cock.

“Where did you learn to do that?” he asked.

“I’ve been studying while I was waiting for us to finally be able to get together,” she said.  “I found a couple of instructional videos on a porn site that showed you how to give a blowjob, and I watched it about half a dozen times,” she explained.  “This was something that the video said to do, so when I saw the precum coming out, well, I just did it!  That was okay, wasn’t it?” she asked, and Mitch smiled as he replied.

“Yes, Sandra, it was,” he said, smiling.  “It most certainly was!”

“Good,” she said, still smiling, “because I’m gonna do it again!”  And she did, placing her lips back on the tip of his cock and sucking, pulling more precum from him as she pumped his cock with her hand.  She squeezed harder on the way up to force the precum up his shaft so she could suck it out and into her mouth.  Mitch could feel it being sucked from him, and it only made him produce more.

‘Holy shit, she’s good!’ he thought to himself as he watched his sister sucking on the tip of his cock, ‘and I haven’t even shown her what to do yet!’  When she finally slid her lips from the tip of his cock and sat back, she looked up at him and smiled, licking her lips.

“Your precum really tastes good, big brother!” she said.  “I just love it!”

“You’re really been studying, haven’t you?” he asked as she pumped his cock with her hand.  She giggled and nodded as she replied, the tip of her tongue sticking out between her teeth.

“I have, yes,” she said, her eyes sparkling, “and I’ve been practicing on my dildo, too.  But I can’t wait to try out what I’ve learned on you because it’s like you said before, I can’t get feedback from a video or a dildo,” she said.

“Then instead of me telling you what to do, why don’t you just show me what you’ve learned on your own?” he said.

“Okay!” Sandra replied, grinning at him.  “This is gonna be such fun!” she said, looking at his cock in her hand, biting her bottom lip as she tugged on his shaft.

Then she leaned forward and, holding his cock in the palm of her hand, opened her mouth and stuck out her tongue, placing it on his smooth-shaven balls. She licked him slowly from the base of his balls to the tip of his cock, pressing the flat of her soft, wet tongue firmly against the underside of his shaft, tickling the sensitive underside of the head of his cock when she got there and making Mitch flinch.  She looked at him and giggled, then did it again.  She licked his cock slowly like this three times, and when he thought she was going for a fourth she surprised him by putting her lips on his balls and sucking, pulling one of them into his mouth.  She wrapped her fingers around his throbbing shaft, gripping it firmly and pumping it slowly as she rolled one of his balls around in her mouth.  Then she switched to the other one, rolling it around in her mouth as well.  She released his ball from her mouth with a soft ‘pop’ and then gave it a quick lick before she looked up at him and spoke.

“Am I doing it right, Mitch?” she asked, looking up at him past his cock in her hand.

“Oh, yeah, you’re doing it right, trust me!” he replied.  She grinned and dropped her mouth down to his balls again.

But this time she really surprised him by sucking not one but both of his heavy balls into her mouth.  She opened her mouth wide and sucked firmly, pulling them in, tugging on his cock as she did.  His precum was flowing like a river now, and she moved her hand up to the head of his cock to spread it down and around his shaft as she rolled his balls in her mouth.  Mitch moaned slightly at the sensations of having his balls sucked like this; he’d only met one other girl who had been able to do this, and he was elated that his sister was able to do it.

After a few moments of this she released his balls from her mouth and then gave them a firm lick with her tongue, then put her tongue on his balls and licked him again, slowly, from his balls all the way up to the tip of his cock.  Then, without pausing, she tilted her head forward and dropped her mouth down onto the head of his cock, clamping her lips closed around it just behind the head.  She immediately applied suction, running her tongue over and around the head of his cock, sucking still more precum from him.  She looked up at him with the head of his cock in her mouth, her eyes asking the question; Mitch nodded at her and smiled, and she smiled back.

Mitch watched as his sister began sliding her mouth up and down on his cock, one hand wrapped tightly around the shaft and pumping slowly as she took more and more of his cock into her wet, sucking mouth.  He sighed as she ran the flat of her tongue along the underside of his cock, and moaned a little when her free hand found his balls.  She began kneading and massaging his balls as she bobbed her head up and down on his cock, her big tits swaying as she took more and more of it into her mouth.  She pushed and pushed and tried as hard as she could, but she could only get about two thirds of it in her mouth.  She held her mouth down on his cock as far as she could get it for a few moments, sucking on it and tugging on his balls, before slowly sliding her mouth back up the shaft, sucking hard as she went.  She slid her lips from his cock and released it with a soft ‘pop,’ then sat back and smiled up at him, her mouth open and her eyes watery.  She had one hand wrapped around his slippery, shiny cock and the other gripping his balls as she spoke, a little breathlessly from her efforts.

“How was that, big brother?” she asked, gasping for breath and releasing his balls from her hand long enough to wipe away the tears from her eyes with the back of her hand.  “Did I do it right?”

“That was amazing, and yes, you did it right!” he replied, returning her smile.  “Right now I don’t think there’s anything I need to tell you about, because so far you’re hitting all the right buttons and making all the right moves.”

“I really wanted to take all of your cock in my mouth, though,” she said, looking a little disappointed.

“That’s a learned skill for most girls, and I’m sure that you’ll be able to do it after a while,” he said.

“You mean after I practice some more on you, right, big brother?” she asked, grinning at him, her hands still gripping his cock and balls.

“Right, baby sister!” he replied, returning her grin.

“Then I better get back to it, huh?” she said.  She dove back down onto his cock, engulfing it in her mouth and bobbing her head up and down, taking as much of it in her wet, sucking mouth as she could while pumping the rest of it and his balls in her hands. 

Mitch just sat there and watched, amazed at how good Sandra had turned out to be just from watching porn videos.  If it were any other girl he’d have thought she had lied to him when she said she’d never done this before, but he knew his little sister well enough to be able to tell when she was lying, and in this case she wasn’t.  She was telling the truth when she said she’d never given a man a blowjob before, but from what he was seeing now she was going to be one of the best.  He’d had his share of blowjobs before, and her first time sucking on his cock was easily head and shoulders above the best blowjob he’d gotten before now.

His little sister was a natural born dick sucker, and that was all there was to it.

After a minute or two more of sucking on her brother’s hard dick and enjoying every minute of it, Sandra slid her mouth from his shaft and looked up at him, her eyes still watery as she spoke.

“I wanna try something I saw in a video, okay, big brother?” she asked, her hand pumping his cock as she spoke.

“Like I’m gonna say no!” he replied, making her smile.

“Yeah, I really didn’t think you would!” she replied.  She lowered her mouth back down onto his cock, taking it all in her mouth again and holding it there for a moment as she had done several times before, tugging on his balls as she did.

Then she slid her mouth up the length of his hard shaft, running her tongue along the underside as she did, stopping when she had just the head and maybe an inch of his shaft in her mouth.  She clamped her lips down tight around his shaft, the flat of her tongue pressing firmly on the sensitive underside of the head of his cock, and began sucking hard – very hard, like she was trying to drink a very thick milkshake through a straw.  She gripped his cock tightly in her hand as she sucked on him, not moving it but concentrating on sucking instead, her other hand massaging his balls as she did.

“NNNGGHH!” Mitch groaned, causing Sandra to look up at him.  She kept her eyes on him as she sucked on his cock, her eyes wide, her cheeks caved in with the suction she was applying.

“Holy shit, sis!” he gasped, amazed at the sensations running through his cock.  “You keep that up and I’m gonna cum in no time!”  She took her mouth from his cock just long enough to reply.

“That’s the whole idea, big brother!” she said, then clamped her wet, sucking mouth back down onto his cock to begin sucking on it again like she had just been doing.  She looked up at him as she sucked on his cock, her cheeks caved in again, her mouth and throat moving as if she was drinking a thick milkshake, the soft slurping, sucking sounds of what she was doing filling the room.  She never took her eyes off of him as she worked on him, pulling and tugging on his balls, gripping his shaft tighter than ever.  He could see in her eyes what she wanted, and he felt it in his balls that he was about to give it to her.

“I’m gonna cum!” he gasped, and to his amazement Sandra increased the suction she was applying to his dick, bobbing her head up and down just a little to take a little more of his shaft in her mouth.  Not much more, maybe half an inch or so, but enough to bring him quickly to the brink of orgasm.  A few more seconds of her tongue against the sensitive underside of the head of his cock combined with the incredible suction she was applying was all it took.  With an involuntary upward jerk of his hips Mitch’s orgasm hit, and his cock exploded in his sister’s mouth like a hand grenade.

“HHNNNGGGHHH!” he groaned through gritted teeth, grimacing with the force of his orgasm.  Sandra cried out in glee around his cock in her mouth, hanging on and keeping up the suction as his cock pumped stream after stream of hot, thick cum into her sucking mouth.  Her eyes were wide as her mouth quickly filled up, his cock pumping and throbbing as he came, and she could feel his cock pulsing on her tongue as his balls emptied themselves into her mouth.  She moved her mouth up a little to make more room for his load of cum, keeping the head clamped between her lips.  She hung on as his cock pumped again and again, quickly filling her mouth up, and when she felt the throbbing begin to slow she pumped his cock with her hand, squeezing harder on the upstroke to push all of the cum out and into her waiting mouth.

“MMMMMMM!” she moaned, looking up at him as she pumped the last bit of his cum from his shaft, his orgasm fading away.  When it was all over he was left gasping for breath, Sandra keeping her eyes on his as she drained the last bit of cum out of him.  Then she slid her lips slowly up the head of his cock, lingering with just the tip between them for a second, then sliding her lips off completely.  She released his cock and balls from her grip, his cock slapping against his abdomen as it fell.  With her eyes still on his she put her hands on his hips on either side of his cock and leaned forward, opening her mouth to show him his cum pooled on her tongue and in her mouth.  She curled the tip of her tongue up to keep it from sliding out and dripping on him, but a little bit of it got away and did that anyway.

Then, to his surprise and utter amazement, Sandra closed her mouth and swallowed.  Then, without any hesitation at all, she lowered her lips down to his cock and sucked up the little bit of cum that had dripped out of her mouth, swallowing it as well.  Then she laid her forearms across his hips, her hands resting on his slowly softening cock, and looked up at him with a big grin on her face as she spoke.

“So how was that, big brother?  Did I do good?” she asked, beaming.

“I don’t know what to say!” Mitch replied, still in awe of the blowjob he’d just received and of how easily his sister had swallowed his load.  “That was without a doubt the best blowjob I’ve ever had, and the way you swallowed without any hesitation at all – that was simply amazing, and hot as hell!” he said, meaning it.

“Thank you, Mitch!” she replied, proud of herself.

“Where in the hell did you learn that last part?” he asked.

“I saw it in a porn video that I watched a few days ago,” she replied.  “The girl’s name was…what was it, something out of ‘Star Wars,’ I think…” she said, her brow furrowing as she tried to remember.

“You mean ‘Princess Leia?’” Mitch said.

“Yeah, that’s it!” Sandra replied, grinning.  “’Princess Leia!’  And from what I saw, she really sucks a mean dick, too!”  Mitch nodded as he replied.

“Yeah, she’s one of the best there is, if not THE best,” he said, agreeing with her.  “You picked a great role model to learn from, that’s for sure.  And you sure didn’t have any problem swallowing, either,” he said, “and that’s unusual.  With most girls it’s a learned skill and an acquired taste, but apparently neither of those apply to you.”

“Apparently not,” she said, sitting upright.  “I figured that if your precum tasted as good as it did, your cum would taste just as good.  And it did, too!” she said, grinning at him.  “I just loved the taste of your cum, big brother!”

“There’s more where that came from, you know,” he replied, grinning at her.  “All you have to do is ask, and it’s yours!”

“I know, I know!” she said, happily.  Then she leaned forward and put her arms across his hips again, resting her chin on the backs of her hands this time and looked up at him with puppy dog eyes as she continued.

“So how long before I can have some more?” she said, smiling, her voice low and husky, the desire plain in her eyes.

‘My God, I’ve created a monster!’ Mitch thought to himself, smiling back at her.  ‘Lucky me!”

                                                             * * * * * * *

The next three days brought more of the same to Mitch, much to his delight and that of his sister.  She sucked another cumload from him after they ate dinner that night, and she was there every night after work for the following three nights, draining him dry each night.  As it turned out, Sandra absolutely loved sucking cock and the taste of his cum, a situation that Mitch was absolutely okay with – as long as it was his cock and his cum, that is.  He had always been protective of his little sister, but now that their relationship had turned intimate he was more protective of her than ever.  Deep down inside he knew it was from jealousy, but he wouldn’t admit that to himself – not yet, anyway.

All Sandra knew was that she loved her big brother, the feeling of his cock in her mouth, and the taste of his cum on her tongue.  She was what Mitch had called a “natural born cocksucker,” and she took that as the compliment it was intended to be.  Mitch had told her that while some guys would use the fact that a girl sucked cock as an insult, deep down inside every man wanted a girl who was good at it and would kill to find someone with half the skills that Sandra had shown him over the past four days.

And she was getting better at it all the time, a fact that was not lost on Mitch and one that pleased him to no end.

Late in the afternoon of the fourth day Mitch got a text message from Sandra telling him that she had to work late, and that she wasn’t going to be able to come over to his house that night.  She also told him that there was a porn video she wanted him to watch instead because there was ‘something in it that I want to try’ and she wanted his opinion on it, so that night after he finished eating he looked the video up on one of the major porn host sites and found it within minutes.  It was another Princess Leia video, and involved an office worker who was taken captive by her boss, tied up and then face fucked.  The video ended with her getting a pretty good facial, and when it was over it left Mitch with some interesting questions, not to mention a raging erection.

He sat back in his chair, looking at the now-blank computer screen, wondering what it was about the video that his sister wanted to try.  Did she want to try being tied up, did she want to try getting face fucked, or did she want to try getting a facial?  Or any combination of the three? 

“Or does she want to try all of them at the same time?” he mused out loud.  Whichever it was, he would have to wait until the next night to find out.

The next day dragged, and Mitch thought that it would never end.  He couldn’t remember when he was as anxious to do something as he was to be with his sister again that night, and when quitting time finally came he dashed out of the building, jumped in his car, and went tearing out of the parking garage like Richard Petty when the flag dropped.  He was home in record time, and fifteen minutes later his doorbell rang.  He almost ran to the door and jerked it open; there stood Sandra, grinning from ear to ear.

“Hi, Mitch!” she said cheerily, stepping into the house and walking past him.  She was wearing the same tight white short sleeved shirt with black piping and the same equally tight black skirt as she was wearing the first time they ever got together, and it had become Mitch’s favorite outfit.  He closed the front door and turned to follow her, but once again she was right there waiting for him.  She threw her arms around his neck and pulled him down to kiss him, deeply and passionately, molding her lithe body against his as she slid her tongue into his mouth.  When she ended the kiss a full minute later she looked up at him and smiled, her eyes sparkling.

“You have no idea how much I’ve been looking forward to this night!” she said breathlessly.

“I think I do, because I’ve been looking forward to it just as much,” he replied, returning her smile.

“Then why don’t we go into the living room and get started?” she said, her voice a husky whisper.

“Good idea,” he replied.

“Did you watch the video I asked you to?” she asked, and Mitch nodded as he replied.

“Sure did,” he said, “but I have a question – what is it exactly in the video that you want to try?  Do you want me to tie you up, face fuck you and cum on your face, or face fuck you and cum on your face without tying you up, or just face fuck you, or what?  All three, maybe?” he asked. 

“No, I don’t think I’m ready for al three – not yet, anyway,” she replied, smiling up at him, her arms still around his neck.  “We can try everything in the video later, but tonight I want you to face fuck me and cum all over my face.  Will you do that for me, big brother?” she asked, looking into his eyes.

“Of course I will,” he replied, smiling down at her.

“Good!  Now let’s go into the living room and get started, shall we?” she said, taking him by the hand and leading him into the living room.  “I would imagine that after four days you’ve got a pretty good load of cum stored up in those balls for me, and I want every drop of it all over my face!” she said, stopping when they got to the couch.  She turned him around so his back was to the couch, put her hands on his chest, and pushed him backwards.  He flopped down on the couch, and before he had even stopped bouncing she was working at his pants, getting the belt unfastened and then the pants themselves.  He barely had time to kick out of his loafers before she had his pants unfastened and was pulling them off, down over his hips and down his legs, he just being able to lift his butt to help her out before they were gone.  He stepped out of them and kicked them to the side as Sandra straightened up in front of him and pulled her shirt open with one quick outward yank of her hands.  Mitch saw that she was wearing the same black bra with gold embroidery on it as she was wearing the first night, and he was pretty sure she was wearing the matching panties as well.  With a sly smile on her face, still looking him in the eyes, she pulled the tail of the shirt out of her skirt and shrugged out of it, dropping it to the floor beside her.  Then she unbuckled the big black belt she was wearing, dropping it to the floor next to the shirt, and then quickly unfastened her skirt, pulling it down over her hips and letting it drop to the floor as well.  Mitch was pleased to see that he was right – she was indeed wearing the matching panties, and she looked as sexy and alluring in them as ever.

“I just love the way you look in that lingerie, Sandra,” he said, looking up at her as she reached for the clasp between the cups of the bra, her big tits jiggling in the bra as she did.

“I know you do, that’s why I wore it,” she replied, smiling as she opened the clasp.  She stopped, then, looking at him with a playful look in her eyes, the clasp open but she still holding the bra in place.

“So do I take this off and let you see my naked tits, or do I leave it on and let you watch them jiggle inside the cups as you face fuck me?” she said, sticking the tip of her tongue out through her teeth as she smiled at him. 

“Decisions, decisions,” he said, smiling back at her.  It took him a few moments to decide, and when he did his decisions surprised her.

“Leave it on,” he said.

“Are you sure, big brother?” she asked.

“Yes, I’m sure,” he replied.  “You can take it off next time, but this time I want to see just what you said – I want to see those big tits of yours jiggling inside the bra as I face fuck you.”

“Okay, if that’s what you want!” she replied, hooking the clasp back together.  Then she dropped down to her knees between his outstretched legs, moving in close and picking up his hard cock with her hand.  She gripped it tightly and pumped it slowly, and it was only a few moments before the first big clear drop of precum appeared at the tip.

“My, someone certainly is anxious tonight,” she said, smiling at him.

“Can you blame me?” he replied as Sandra leaned forward and licked the drop of precum from the head of his dick, swallowing it.  Then she put her lips over the tip and sucked, pumping his cock in her hand, and slowly sucked the head into her mouth.  She stopped when she had just the head in her mouth, sucking harder and pumping his cock to get the precum out of him.  Mitch moaned as she did this, and he could feel the precum being sucked out of him.

“Damn, I love it when you do that!” he gasped; Sandra looked up at him and smiled around the head of his cock in her mouth, then went back to what she was doing.  She sucked on the head of his cock for a few more moments, then slid her mouth further down the shat, taking more than two thirds of it in her mouth as she moved her hands out of the way, placing them on the tops of his thighs.  She held it there and sucked on it for a moment, running the flat of her tongue along the underside as she sucked, her cheeks hollowing in as she increased the suction.  Then she pulled her mouth slowly back up his shaft, sucking and rubbing with her tongue along the way, making Mitch gasp with surprise.

“Wow, that’s something new!” he gasped as Sandra stopped with the head of his cock in her mouth.  “Where did you learn that from?” he asked.  Sandra slipped his cock from her mouth just long enough to reply, holding it in her hand as she did.

“Came up with that one all on my own!” she said proudly, smiling.  Then she slid her mouth back down onto his cock and did it again, making Mitch groan again.

“I think it’s time to do what you came here for before you make me blow my load in your mouth,” he said.  Sandra looked up and him and nodded quickly, urging him on. 

Mitch reached down and took her head in his hands, one hand on either side of her head and, holding it firmly but not hard enough to hurt her, began moving her head up and down on his cock.  Sandra moaned as he did this, her hands on top of his thighs as he pushed her mouth up and down on his cock.  She sucked as much as she could, running her tongue along the underside as her mouth was moved up and down, and after a few moments of being gently face fucked like this she was ready for more.  She told Mitch this by putting her hand on the back of her head and pushing down a couple of times, hoping that he would get the hint.

He did, and began forcing her mouth further down onto his cock.  She nodded quickly to let him know that was what she wanted, so Mitch gripped her head a little tighter and began pushing her mouth further down onto his cock, increasing the force and the tempo just a little.  It only took a couple of strokes before Mitch pushed Sandra’s head down far enough and hard enough for the head of his cock to hit the back of her throat.

“GLCK!” she gasped, slapping her hands down on the top of his thighs as she gagged on his cock.  Thinking that he had hurt her Mitch released her head from his hands, and when he did Sandra pulled her head up and gasped for air as she spoke, a thick strand of saliva running from her bottom lip to the head of his cock.

“Don’t stop!” she gasped, her eyes beginning to water.  “Keep going, I like it!” she said, grabbing his cock and shoving her mouth back down onto it. 

Knowing what she wanted, Mitch grabbed her head in his hands again and began face fucking her once more, a little faster and harder this time, driving her mouth up and down on his hard cock with her head in his hands.  He pushed down hard enough to make her gag on his cock again and held her there for a moment, her back arching as she slapped her hands down on his thighs again, crying out around the cock buried in her throat.  Then Mitch began moving her head up and down again, with Sandra breathing hard through her nose. 

“MMPH!  MMPH!  MMPH!  HMMPH!” she cried out around his cock as he face fucked her harder and faster, gripping her head tightly in his hands.  Sandra looked up at him for a moment, and in that moment he could see in her watery eyes that he was giving her exactly what she wanted, so he continued for another full minute before releasing her head from his hands.  When he did Sandra sat back on her haunches, whooping and gasping for breath, a thick strand of saliva hanging down from her bottom lip to fall into her cleavage.  She sat back on her hands and looked up at him through watery eyes, her mouth hanging open in a smile, her chest heaving as she gasped for breath.

“Fuck yes!” she gasped, grinning up at him.  “Just like that, big brother, just like that!  Fuck my face, fuck my face like the little cum slut that I am!” she said, sitting forward and grabbing his cock in her hand to stuff it in her mouth again.  Mitch grabbed her head in his hands again and began face fucking her, harder and faster this time, Sandra moaning and groaning around his cock in her mouth as he did.  He really let her have it this time, fucking her mouth harder and faster than ever, and the harder he did it the more she seemed to enjoy it.

And the truth of it was that Mitch was enjoying it, too, almost as much as she was.  The feeling of power and having control over his sister was intoxicating, and he knew it would be easy to get carried away – so he resolved himself right then and there to make sure he never did.  The last thing he wanted was to hurt his sister in any way, and he would make sure he never did.

But right now he wanted to give her what she wanted, and he felt the familiar sensation in his balls which told him he was getting ready to cum.  This one was going to be huge, he could tell, and he just hoped that Sandra was ready for it.  He felt his balls shift again, more urgently this time, so he warned her about what was getting ready to happen.

“I’m gonna cum, sis!” he gasped, feeling his orgasm building quickly.  She looked up at him and pulled her head back, telling him to let go which he did; she immediately grabbed his glistening, slippery cock in her hand and began pumping furiously, gripping it tighter than she ever had before.

“Cum on my face, cum on my face!” she gasped, holding his cock close to her face as she pumped in in her hand.  “Give it to me, big brother, give me that cum!  Cum all over my face!”

That was all it took.  Mitch’s cock exploded in her hand and he groaned as the first blast of cum came rocketing out of his cock, hitting Sandra on the cheek and splashing up her face and into her hair.

“Yes!  Yes!  Yes!  Yes!” she gasped as his cock pumped and throbbed in her hand, shooting out stream after stream of hot, thick cum that landed all over her face.  Three, four, five, six times his cock pumped in her hand, a long rope of cum blasting out and landing on her face each time.  It only took a matter of seconds for her face to be covered with his cum, and when she felt his orgasm start to fade she clamped her mouth around the head of his cock, taking the last few jets of cum in her mouth.

“MMMMMMM!” she moaned as his cock pumped on her tongue, reveling at both the sensation of his hot cum on her face and tongue and at the taste of it.  She kept her mouth locked onto his cock as his orgasm faded, sucking the last bit from him and pushing it up with her hand when the pulsing and pumping of his cock finally stopped.  She pumped his shaft a few more time, pushing the last bit of cum up, sliding her mouth from his cock until just the tip was between her lips.  Then she slipped her lips from it and sat back, releasing his cock to slap wetly against his stomach as she sat back on her hands, opening her mouth to show him his cum on her tongue.  She ran her tongue through it twice, sloshing it around in her mouth, then closed her mouth and swallowed.

“Mmmmm, I just love the taste of your cum, big brother!” she said, smiling at him.  Then she began wiping the many ropes of cum from her face with her fingers, and Mitch watched as she put her fingers in her mouth and sucked the cum from it.  She did this until her face was relatively clean of cum, smacking her lips with delight as she sucked the last bit of cum from her fingers.

“Saw that in a video, too!” she said, smiling up at him.  “Did you like it, big brother?  Did you like watching me wipe your cum from my face and swallow it?” she asked, teasing him.

“Oh, yeah,” he replied, returning her smile, “almost as much as I enjoyed shooting it all over your face!”

“That was so fuckin’ hot!” she said, grinning up at him.  “And the way you face fucked me – wow!  I just loved it, every second of it!”

“I didn’t hurt you?” he asked, and she quickly shook her head no.

“Not a bit!” she said emphatically.  “Actually, you could have done it harder if you wanted to,” she said, surprising him. 

“Next time I will,” he said, returning her smile.  “Assuming you’re going to want there to be a ‘next time,’ that is,” he said.

“Hell, yes, there’s going to be a ‘next time’!” she said, getting up on her knees and leaning forward, bringing her face close to his, her big breasts hanging down in front of her in that sexy bra he loved so much.  She gave him a sly smile as she spoke again, her voice low and hushed.

“And who knows what else will happen ‘next time,’ big brother!” she said, that same sly smile on her face.  Then she got up quickly, getting to her feet before he had time to react, picking up her clothes from the floor as she spoke.

“Right now I’m going to use your bathroom to finish cleaning your cum from my face and hair,” she said, turning to face him, “and when I come back I expect a nice, cold beer waiting for me on the coffee table!”  Then she turned and walked out of the room, treating Mitch to a spectacular view of her equally spectacular ass as she walked away.  Mitch grinned to himself as he watched her go.

“I have indeed created a monster!” he said to himself, chuckling.  Then he reached down and picked his pants up from the floor and got dressed, then went into the kitchen to get them both a beer.
