What Mitch thought was only going to be one more hand job from his sister turned out to be several.  Sandra called him the next day on her lunch break to thank him for helping her the night before and told him that she had “done some research” on giving a good hand job when she got home.  When Mitch asked her what the “research” was, she told him that while she was washing clothes she went on the internet and did a search for ‘hand job techniques’ and had discovered a plethora of porn videos on the subject.  She spent the rest of the evening watching them, and she was anxious to try out some of the techniques she had seen in the videos.  She asked Mitch if she could come over that night and practice on him some more, and of course he agreed. 

A mere ten minutes after she arrived Mitch found himself once again sitting on the couch, his jeans down around his feet with Sandra sitting on her haunches between his legs, her hands wrapped tightly around his cock as she pumped it in her hands, trying her best to milk the cum from him.  She had brought a very popular and very expensive bottle of lubricant with her – a trick she learned from the videos, she said – and she used it to both get him hard and get him off.  She had also dressed for the occasion, wearing a pair of skin-tight denim shorts and a red plaid halter top that showed about a mile of cleavage, especially when she had both hands wrapped around his cock and her breasts were pushed up between her arms.  Mitch was pretty sure she was doing this on purpose, and the smile she gave him when she caught him looking at her tits only verified this.

It didn’t take her long to make him cum; when he did it was just as hard as the previous night, his cock once again erupting in a flood of jizz that flew out of his cock and splattered all over his cock, stomach, thighs, and Sandra’s hands and arms.  And Sandra enjoyed it more this time than she had the night before, grinning like crazy and laughing out loud when his cock erupted in her hands.  She had played his cock like a fine musical instrument, using the palms of her hands and her fingertips to stimulate the most sensitive parts of his cock – namely, the frenulum and the underside of the head – and the result was an earth-shattering orgasm and a flood of cum.  She was an apt pupil and was getting very good at giving hand jobs very quickly.

The following night Sandra came over again and this time she made him cum twice, edging a small orgasm out of him by holding back when he started to cum, then resuming her efforts after a few moments to bring him to another bigger, earth-shattering climax a few minutes later.  The sight of her huge tits wobbling around inside her snug V-neck t-shirt without benefit of a bra certainly helped.  He knew Sandra was enjoying it almost as much as he was because her nipples were rock hard the entire time, clearly visible through the thin cotton of the shirt she was wearing.  He could also detect the faintest trace of female musk in the air right before his cock exploded in her hands.

“Where the hell did you learn to do that?” he gasped when he stopped cumming.  Sandra grinned at him as she replied.

“From the videos I’ve been watching,” she said, maintaining her tight grip on his cock, slowly milking the last few drops of cum out of him.  “So did you like it?”

“I think I’ve created a monster!” he said in reply, still gasping for breath. 

“You ain’t seen nothing yet, mister!” she said, a wicked smile on her face.  “Just wait until I show you what I’ve learned about giving blowjobs!”

“So you’re still watching those ‘instructional’ porn videos on the internet?” Mitch asked, grinning back at her.  Sandra nodded as she replied, releasing his glistening, slippery, and softening cock from her hands and reaching for the hand towel she had brought with her.  She wiped the leftover lube and his cum from her hands as she replied.

“Yep, I sure have, and I’ve been practicing giving blowjobs on a dildo I bought just for that!  I can’t wait to try out what I’ve learned on a real cock, namely yours!” she said, her eyes sparkling.

“First things first,” Mitch said, sitting up.  “I was supposed to teach you about tit fucking first, remember?” he asked.

“I remember,” Sandra replied, picking up a second clean hand towel which she used to clean up Mitch’s cock and stomach as well, her big tits swaying inside her shirt with her every move.   “So is that what we’re going to do next?” she asked, her eyes bright.

“One step at a time, baby sister,” he replied.  “You have to crawl before you can walk, you know!”

“How about two nights from now?  That will give me time to do some more research and watch a few more videos!” she said, grinning at him. 

“It will also give me some time to recover; you’ve really been draining me dry for the past few nights, you know?” Mitch replied, grinning back at her.

“You’ve been handling it just fine, I think!” she said, standing up and looking down at him.  The view of her spectacular bustline was fantastic from this angle, and Mitch couldn’t wait to get those monster tits wrapped around his dick – and maybe he’d be lucky enough to get his lips on them as well.  He hoped he would, anyway. 

“So same time, two nights from now?” she asked, her fists on her hips, a hand towel in each.  Mitch nodded as he replied.

“Works for me!” he replied.

“Great!  See you then, big brother!” Sandra replied before she leaned over and kissed him on the cheek.  “I’ll put the hand towels in the hamper on the way out, okay?” she said, and Mitch just nodded.  A few moments later the hand towels were in the hamper and Sandra was gone, driving away in her car, while Mitch was still sitting on the couch with his jeans around his knees, smiling at how things had turned out and about what was going to happen next. 

After a few moments he stood up, pulled up his jeans, then went to get another beer before sitting back down on the couch to watch some TV.

* * * * * *

The next two days passed slowly for Mitch, who was unable to get the images of his sister’s big tits swaying and bobbing around as she jerked him off out of his head.  That, coupled with the anticipation of actually getting to see them, maybe getting to touch them, and absolutely having them wrapped around his hard cock made it next to impossible for him to concentrate.  He was absolutely positive that his sister had been teasing him, and he couldn’t help but wonder what she was up to.  This whole thing had started out with him being the teacher and her being the student, but that was pretty much all over now – Sandra had taken the reins from him by going on the internet and learning all of what she wanted to know and more, and instead of him being the teacher he was now the visual aid.

And to be honest, he was just fine with that.

The night of Sandra’s first tit fuck finally arrived and so did she, right on time as usual.  And as usual, she was wearing a very snug-fitting outfit that clung to her body in all the right places and in all the right ways.  She was wearing a gold silk sleeveless V-neck top, the neck of the top cut low enough to show a more than ample amount of cleavage courtesy of the push-up bra she had to be wearing, and the same snug black high-waisted skirt and wide belt that she wore the first night she came by.   A pair of black high heeled shoes and a small black patent leather purse suspended from a chrome chain completed her outfit.  If she had worn that outfit to work then Mitch was sure every male who saw her ended up walking around with an erection for the rest of the day – and he was fairly certain that she had in fact worn that outfit to work.

“Hi, big brother!” she said cheerily, a big smile on her face as she breezed past him into the house and headed towards the living room.

“Hi, yourself!” Mitch replied, closing the door and turning to follow her into the living room.  He couldn’t help but notice and admire the flexing and wiggling of her ass in the tight skirt as she walked in front of him, and he felt a stirring in his crotch.  He didn’t notice any panty lines, so she either wasn’t wearing any or she was wearing a thong.  Either way, the view was spectacular, and he was a little disappointed when she sat down in what had become her usual chair.

“So I have to ask, baby sister, did you wear that outfit to work?” he said, sitting down in his usual place on the couch.  A big smile crossed Sandra’s face as she replied.

“I sure did, and from what I saw the guys in the office loved it!” she said, cheerily.  “I knew that I was going to have to work late and would have to come here straight from work, so I dressed in something I knew you’d like.  Besides, I have to admit that I like teasing the men in my office by wearing things like this!  It’s so much fun to watch them struggle not to stare at my tits and to see them trying to adjust their erections in their pants without being seen!” she said, giggling at the last part.

“Just be careful, that could get out of hand if you tease the wrong person,” Mitch cautioned.

“I know, big brother, and I appreciate your concern, really I do,” she said, a serious look on her face, “but lube isn’t the only thing I carry in this purse!”  She put the purse on her lap and opened it up, reaching inside and pulling out a small taser.  She grinned as she held it up for him to see, then put it back in her purse and pulled out the bottle of lube.

“So shall we get started?” she asked, holding up the bottle of lube and smiling sweetly at him.

“Anxious, are we?” Mitch replied, teasing her.

“Yes, very!” she said, standing up and putting the purse on the chair behind her, then walking over to him and kneeling down between his outspread knees.  “I’ve learned so much about pleasing a man and how to make him cum that I’m anxious to put what I’ve learned to use,” she said, reaching up and unfastening his shorts as she spoke, showing Mitch a generous amount of cleavage and letting him watch her huge breasts as they moved inside her shirt and bra. 

“I’m especially anxious to get to the part where I get to give you a blowjob!  I’ve watched a lot of videos on that and have been practicing on my dildo, but I can’t wait to do it to you!  You’ve got a great dick, Mitch, you know that?” she said, smiling as she tugged his now-open shorts down over his hips and sliding them down his legs, with him stepping out of one of the legs of the shorts when they were around his feet.  His cock was semi-hard already, and she smiled when she saw it lying across his thigh.

“I see I’m not the only one who’s anxious!” she said, looking up at him and smiling as she grasped his cock in her hand, squeezing it and then pumping it slowly.

“Can you blame me?” he said, smiling back at her.  “After all, you’ve been teasing me with those big tits of yours ever since you walked in, just like you did to all the guys in the office!  Of course my dick is gonna get hard, seeing those big things bouncing around like that!”

“Well, let’s see if I can make it a little bit harder, shall we?” she said, sitting back and pulling her shirt out of the waistband of her skirt.  Quickly and without hesitation she pulled the shirt up and over her head, tossing it onto the chair behind her, then turned and gave Mitch his first unobstructed view of her magnificent tits.  She was wearing a black lace push up bra that held her tits up high, the cups barely covering her nipples and areolas.  She grinned as she saw the look on her brother’s face when he saw her big tits for the first time.

“You like what you see, big brother?” she said, her voice low and seductive.  Mitch nodded as he replied, his eyes locked on her huge tits.

“Oh, yeah!” was all he could manage, and Sandra giggled at him as she reached out and grasped his cock in her hand again, wrapping her fingers around it and squeezing firmly.  She started pumping his cock slowly, reaching up to fondle his balls with her other hand, keeping her eyes on his the whole time.

“I love feeling your cock growing in my hand!” she said, her voice low, a smile on her face.  “It’s getting bigger and harder, and I can feel it pulsing as it grows!  I love it!” she exclaimed, her smile getting bigger as she continued to slowly pump her hand up and down on his quickly hardening shaft. 

Mitch sat back and watched her work, his eyes going from her massive tits to her hand on his cock and back to her tits again.  She had his cock rock-hard and throbbing in no time, and it wasn’t long before a big drop of clear pre-cum appeared at the tip.  Sandra grinned when she saw it.

“That’s what I’ve been waiting for!” she said happily, sliding her thumb over the head of his cock to spread the pre-cum around and making him jump in the process.  “That means you’re ready, so it’s time to get down to business!”  she said, grinning at him.  She reached around behind her and unfastened her bra, the sides falling away as she held the cups in place with her hands.  She looked at Mitch and giggled as she spoke again.

“Are you ready to see my tits, big brother?” she asked, teasing him.  “I know you want to; you haven’t been able to take your eyes off them ever since I got here!  So are you ready to see them now?”  she said, giving him a sly smile.  Mitch nodded as he replied.

“Beyond ready,” he said, smiling back at her.

Sandra pulled the bra away from her big tits, and Mitch’s mouth fell open as he saw them naked for the first time.  They were huge, full and firm with very little sag, standing out proudly from her chest like twin torpedoes.  They were capped by two light pink areolas of average size, and in the center of each was a hard nipple that was a darker shade of pink.  Her tits were longer than they were round, but they were still huge.  He was immediately reminded of the famous adult model from the ‘60s, Cynthia Myers, and this only made his cock throb more.  Sandra sat upright, her arms held down by her sides with her hands in her lap, thrusting her mammoth tits out to him for him to admire.  She looked down at his cock and saw it pulsing slightly, and she felt the first traces of moisture begin forming in her pussy.

Mitch didn’t know it and had no way of knowing, but every time she went home after she finished making him cum she would go into her room, strip naked, then fall back onto her bed and masturbate herself to orgasm while thinking about her brother’s cock and the massive cumloads it had shot all over her.  She could only imagine what it would feel like to have that thick cock sliding in and out of her wet pussy before he came, pumping his massive load deep inside her.  She fervently hoped that one day this particular fantasy would come true, and soon.

And if she had her way it would.

But right now she was intent on giving him the best tit fuck she possibly could.  From what she had read and seen on the internet there was nothing to it.  She slid her hands up her body and held her tits up for him to see, lifting the firm, heavy, torpedo-shaped mounds out for him to see.  She grinned when she saw the look on his face and giggled at his reaction when she pulled on her own nipples.

“You like my big tits, big brother?” she asked, tugging on her nipples again.

“Oh, yeah,” Mitch said, mesmerized by her huge mounds.  “Those are the biggest tits I’ve ever seen – at least in person, anyway,” he said, looking up at her for a moment before looking back down at her tits again.

“I’ve been looking forward to wrapping my big tits around your hard cock and making you cum between them,” she said, moving in closer, still holding her big tits in her hands.  “It’s going to feel so good for both of us!” she said, smiling at him.  When she was right up next to him she lifted them up and dropped them on his hips on either side of his cock, then picked up his cock and held it straight up as she wrapped her tits around it, pushing them together firmly.  His entire cock disappeared between her tits, not even the tip showing, and Sandra immediately began sliding them up and down around his shaft.

“Mmmmm, that feels good,” she cooed, looking at him with a sly smile on her face. “I love the feeling of your big dick between my tits, big brother,” she said as she slid her tits up and down on his cock.  His precum was really flowing now, and it was only a matter of about a minute or so before his entire cock and her cleavage was coated with it, enabling her to slide her tits up and down on it with ease.

“You like that, Mitch?” she cooed, her voice soft, a sly smile on her face.  “You like my big tits wrapped around your dick like this?”

“Oh, yeah,” Mitch replied, watching her as she tit fucked him, sliding her big tits up and down on his cock.  Every now and then the tip would poke through her cleavage, but only when she pushed down really hard.  Other than that, his cock was completely swallowed up by her huge mounds.  She pushed them together tighter around his cock, her mouth open slightly as she smiled at him.

“How’s that?” she asked, her voice low and soft.  “You like it when I squeeze them tight around your dick?” she said as she slid her tits up and down on his cock.

“I love it,” he replied, reveling in the feeling of her soft, warm titflesh pressed tightly around his cock.  He’d fucked a girl’s tits before, many times before, but none of the girls he’d done that with had tits that were even half the size of his sister’s, and his cock being totally engulfed like this was something entirely new to him.  He felt the first stirring in his balls as he watched his sister sliding her tits up and down, looking down as she did, and he knew that it wouldn’t be long before they both got what they wanted.

“I can’t wait to feel you cum between them,” Sandra said, looking down as she continued to slide her tits up and down on his cock. 

“I don’t think you’re going to have that much longer to wait, baby sister,” he replied.  She looked up at him quickly, smiling.

“Really?” she said, her eyes sparkling.  “Will it help if I do this?” she said, squeezing her tits together even harder and moving them up and down faster.

“Oh, yeah!” Mitch replied, feeling his balls shifting a little bit.  Sandra tit fucked him hard and fast for the next few moments, each stroke of her big, firm tits around his hard cock bringing him closer and closer to cumming.  She looked up at him every now and then, grinning from ear to ear, anxious for him to cum between her tits.  After a few more moments Mitch let out a soft moan, and her face lit up as she realized what was about to happen.

“Cum for me, Mitch!  Cum for me!” she said, looking him in the eyes as she moved her tits up and down.  “Shoot that hot cum all over me, cover my big tits with it!” she urged, grinning from ear to ear.

“Oh, shit, I’m gonna cum!” Mitch moaned, and a split second later he did.  He bucked his hips upward and groaned through gritted teeth as he came, his cock exploding between Sandra’s huge tits.  She pushed her tits down hard and let the head poke through, a long stream of thick cum shooting out up into the air to fall back and land all over her tits and hands.  She cried out in gleeful surprise at this, pushing down on her tits hard enough to let the same thing happen two more times.  Mitch came hard, very hard, and it felt like he was shooting a gallon of cum out of his throbbing, pulsing cock.

“That’s it, big brother, that’s it!” Sandra cried as his cock kept pumping out more and more cum, “Cum all over me, cum all over my tits!” she said, sliding her tits up and down again and again.

Mitch had never cum so long and so hard in his life, and when his orgasm finally faded away and his cock stopped pumping out cum, Sandra’s hands and tits were covered with it.  She pushed her tits down and pressed them hard around his cock, squeezing the last bit of cum out of him with her tits, and when she was sure she had it all she released her tits.  They separated and his cock fell out, covered with his cum and slapping wetly against his stomach.  His orgasm had left him gasping for breath; they both looked down at his cock and Sandra laughed as she spoke.

“Holy crap, Mitch, that’s a lot of cum!” she said, looking up at him with a smile on her face, holding her cum-covered hands out to the sides above his cock and her tits. 

“Well, you told me to cover your tits with it, didn’t you?” he gasped, returning her smile.

“And you sure did, no doubt about that!” she replied. 

“I think I need a towel,” he said, looking up at her.  She nodded and started to get up as she spoke.

“I got it,” she said, getting up and using her elbows for support instead of her cum-covered hands.  “You stay right there and I’ll be right back,” she said, getting to her feet and then turning to walk out of the room towards the bathroom.  She returned a minute or so later, two hand towels in her hands; her hands had been wiped clean, but her huge tits were still covered with his cum.  She walked over to him and handed him a hand towel, smiling down at him.

“Here you go!” she said. 

“Thanks,” he said, taking the towel from her.  They spent the next minute or so cleaning up, Mitch finding it arousing to watch Sandra wiping his cum from her huge mounds, and when they were both finished she took the hand towel from him and went back to the bathroom to put them in the dirty clothes hamper.  He stood up and pulled his shorts back on while she was gone, and when she came back into the room she picked up her discarded bra and shirt from the floor, putting them back on and giving Mitch another show as she tucked her big tits back into her bra.

“Well, what do you think?” she asked as she tucked her tits into the cups of her bra.  “Did I do good?”

“You made me cum, didn’t you?” he replied, and she nodded, a smile on her face.

“Boy, I’ll say!” she said, pulling her shirt back over her head and then tugging it down into place.  “I didn’t think you were ever gonna stop cumming!  I mean, you shot cum all over the place!”

“Is that a problem?” he said, kidding with her as he walked over to the kitchen to get a beer out of the refrigerator.

“No, not at all!” she replied, following him into the kitchen and holding out her hand.  He looked at her and she looked back at him, both of them silent for a moment before she spoke again.

“Hey, if I’m old enough to give my own brother a hand job and then tit fuck him, I’m old enough to have a beer, don’t you think?” she said, smiling up at him.

“Yeah, I guess so,” he said, returning her smile and handing her a beer.  They went into the living room and sat down, he in his chair and her on the couch, each of them opening their beer and taking a drink.

“So what’s next, big brother?” Sandra said, obviously eager for the next step.  “Do you think I need to tit fuck you again before we move on to the next step?” she asked.

“Not unless you want to,” he replied, crossing his legs and sitting back in the chair, beer in hand.  “Other than that, I think you’re ready to move on to the next step,” he said, and Sandra smiled as she replied.

“And the next step is giving you a blowjob, right?” she asked, her eyes sparkling.

“It is that,” Mitch said, nodding and smiling.  “You think you’re ready for it?” he asked, and it was her turn to nod and smile.

“You have no idea, big brother,” she said, her voice going low and sultry, “you really have no idea!”
