Twin Sister's Surprise

 (Author’s note:  This is a short little ditty I wrote on a whim; an idea for a very short story came to me and I wrote it while the idea was fresh in my head.  It only took me about two hours to write, and I sincerely hope that the quality of the story hasn’t suffered due to that.  I could very easily turn this into a series of stories, but that, I feel, would take away from the impact that telling about this one brief encounter would have, so this story will remain as just one short story of the first brief but intense encounter between a twin brother and sister.  I hope you enjoy it!

It was the last summer vacation before college started in the fall, and having just graduated from high school Paul was anxious to start the next stage of his life.  His summer job kept him pretty busy, but the money was good and came in handy for when he did have the time off, and he was enjoying some of that time off now.  He was relaxing on the couch in the den, his feet up on the coffee table with his legs crossed at the ankles, a soda sitting on the end table next to the couch.  His parents were gone for the evening, attending some big work-related gala of his father’s, and his twin sister Penny was gone as well.  She was out on a date, and Paul didn’t expect any of them to be home before midnight at the earliest, maybe later.

So Paul took advantage of having the house – and the big screen LED TV – all to himself by watching one of his favorite porn videos, a POV-style video where a woman who gets fired from her job as a secretary gets her job back by going to her boss’s house at night and giving him a blowjob that turns into him face-fucking her silly.  This particular porn actress was his favorite for a couple of reasons – she was a very good actress, an expert cock sucker, and was stunningly beautiful.

She also looked very much like his twin sister, so much so that if you put all three of them together in the same room you’d think you were looking at triplets. 

But the main difference between the porn actress and his sister was her chest.  Penny was built like the proverbial brick shithouse, and while the porn actress had a big chest his sister’s was easily twice as big.  Paul didn’t know what her actual measurements were, but if he had to guess he would have guessed that his sister was a 36DD, maybe even a DDD.  All Paul knew was that his twin sister’s tits were huge, and he would have loved to get his hands on them.

But of course, that was never going to happen for the obvious reasons. 

Paul was about halfway through the nineteen and a half-minute-long video when he heard the front door open and then close.  He could tell by the footfalls on the hallway floor that it was his sister and judging by how fast she was walking he guessed that she was upset.  He paused the video as Penny came into the room; he wasn’t worried about her knowing that he was watching porn because like most twins, he and his sister were very open with each other and didn’t keep anything secret between them.  She not only knew that he liked watching porn but watched it with him sometimes as she liked watching it too.  When she came into the room Paul could see that he was right – she was upset about something.  She stopped in the entranceway and looked at him, a slight scowl on her face.

“Tell me something, Paul,” she asked, standing there with a stern look on her face.  She was gorgeous and sexy as hell as usual, wearing a tight pink top with spaghetti straps that really showed off her big tits and a short as hell black and plaid “schoolgirl” type skirt that showed miles of leg and probably some ass when she bent over as well.  She had a pair of black flats on her feet, and a small clutch purse dangled from a silver chain slung over one shoulder.  He could see the straps of a pink and white bra going over her shoulders with the straps of the top, and from having seen her lingerie before he knew just which one it was – the hot pink with white lace one.

“What’s that, sis?” he said.

“If you had a date with someone who looked like me and showed up dressed like this, would you go get drunk and get a case of ‘whiskey dick,’ or would you throw me down and fuck the living shit out of me?” she asked.  Penny had a sailor’s mouth when she was mad or upset and could curse with the best of them.  She always spoke frankly anyway, but it was worse when she was drunk or mad – and right now she was mad. 

“I’d throw you down and fuck the living shit out of you, for sure,” he replied.  He and his sister had always spoken freely and frankly with each other, and this was no different.  “But I take it your date chose poorly?” he asked, already knowing the answer.

“Damn right he did, the stupid son of a bitch!” she said, walking over to the couch to sit next to him.  She dropped her purse on the coffee table as she sat down, propping her feet up on the coffee table as Paul had done, holding out her hand.  Paul handed her his soda and she took a drink, then handed it back.  He took a drink and then put it back on the end table as she continued.

“I was ready to suck his dick so hard he’d have to pull his underwear out of his asshole, and he goes and fucks it all up by getting drunk at the party before I had a chance!  Asshole…” she grumbled, crossing her arms beneath her massive chest.  She was showing Paul about a mile and a half of cleavage, and he really appreciated the view.

“How did you get home?” Paul asked.

“Katy brought me,” she said, naming her best friend from high school.  “She’s pissed too because her boyfriend did the same fuckin’ thing, so it looks like neither one of us is getting laid tonight!”

“And I daresay it’s gonna be a while before the boyfriends get laid as well,” Paul said, a smile crossing his face.

“You got that shit right!” Penny said, looking over at him and smiling herself when she saw his smile.  That broke her mood, and she nudged Paul as she turned back to face the TV hanging on the wall.

“Oh, you’re watching porn!  Perfect!” she said, meaning it.  “I’m in just the right mood to see some serious dick sucking, and this woman is the best I’ve ever seen – next to me, anyway!” she said, glancing over at Paul as she stuck the tip of her tongue out from between her teeth.  She nudged Paul again and he nudged her back, both of them laughing.

“So hit ‘play’ already, willya?” Penny said, and Paul did.  The video resumed at the point where the actress was kneeling on the floor in front of her boss and between his spread knees and was just telling him how she’d crawl under his desk and pop his cock into her mouth and suck him off while he was on a conference call.  They watched in silence as the actress challenged her boss and he grabbed her by the hair and began face-fucking her, and after a minute or so of watching this Paul noticed two things:  his cock was starting to get hard, and his sister’s breathing was coming faster.  He looked over at her and saw that her mouth was hanging slightly open and her eyes were a little glazed; he looked down and noticed that her nipples were rock-hard and poking out against her shirt, her massive chest rising and falling with every breath she took.  Seeing this made his cock twinge and grow a little more, so he looked back at the TV before she noticed he was looking at her and was a little surprised when she spoke a moment later.

“Man, he’s really face-fucking the hell out of her, isn’t he?” she asked, her voice a little lower than it was.

“Yeah, and she looks like she’s really enjoying it,” Paul replied.

“I’m sure she is!” Penny said.  They watched in silence for a minute or so more, and then Penny changed position on the couch.  She moved away from him and put her legs up on the couch, then lay down and put her head on Paul’s lap.  This took him totally by surprise, and even though he was as open and honest with Penny as he was, he still didn’t want her to notice the hard-on he was getting from watching both the video and her physical reactions to it.

“Penny, what are you doing?” he asked, holding his arm up out of the way while she got comfortable.

“I’m laying down and putting my head on your lap, what does it look like I’m doing?” she replied, settling down next to him.  She put her head on his lap about three inches up from his cock, resting her right hand on the top of his right thigh.  He put his hand on her right shoulder and let it rest there, turning his attention back to the video.

‘Man, that guy really is face-fucking the hell out of her!’ Paul thought to himself, watching the screen as the woman pulled her head away from the man’s cock, a long, thick strand of saliva running from her mouth as she did.  She only had a second or two to catch her breath before the man grabbed her head and forced her mouth down onto his cock again, forcing her head up and down on his shaft as she sucked on it.

Paul could feel his cock continue to grow and get bigger, and he knew there was no way that Penny couldn’t notice it considering it was happening less than three inches in front of her face.  He was still watching the video when he suddenly felt a hand on his cock, rubbing it through his jeans.  He looked down to see Penny’s hand moving up and down on the lump of his cock, her eyes intent on the TV as she did.

“Uh, Penny?” he said, stunned.

“What?” she replied.

“What are you doing?” he asked. 

“Nothing,” she replied, still rubbing his cock through his jeans.

“Nothing?” he asked, confused.

“That’s right, nothing,” she said, still watching the video.

Totally confused and more than a little excited by his sister rubbing his cock, Paul sat still and said nothing more.  Penny continued rubbing his cock through his jeans for another minute or so, and then she unzipped his jeans, reached inside and grabbed his cock in her hand.  Before Paul could reach or say anything she had pulled it free of his boxers and jeans, tugging on it until it was completely outside of his jeans.

“Uh, PENNY…” he said again, catching his breath as his sister gripped his quickly hardening cock in her hand, pumping it to full hardness.

“What, Paul?” she replied, not moving her head or turning it to look at him.

“You have your hand wrapped around my cock!” he said, not believing what was happening to him.

“No, I don’t,” she replied casually as she tugged on his now-fully erect cock.

“Uh, yes, you do,” he said.

“No, I don’t,” she replied, a little more insistently.

Paul was astounded and totally confused.  He didn’t know what to do, so he did the next best thing – nothing.  He sat there and let his twin sister tug on his cock while her head was lying in his lap, both of them watching a porn video as it was happening.  The video had progressed to the part where the face-fucking had ended and now the secretary was “doing what she did best” – namely, giving her boss a wet, sloppy blowjob which she seemed to enjoy almost as much as she enjoyed getting face-fucked. 

Paul nearly jumped out of the couch when Penny moved her head down and put her mouth on his cock, sucking the head into her mouth and slathering her tongue around it as she continued to grip it with her hand.

“WHOA!” Paul cried out in surprise.  “Pen – uh, Penny?” he said, gripping the arm of the couch with his left hand and the back of the couch with his right, having thrown his arm onto the back of the couch for support when his sister sucked his cock into her mouth.

“What, Paul?” she said, taking her mouth from his cock just long enough to speak before slipping her mouth back onto it again.

“Uh, you’re…you’re sucking my dick, Penny!” he said, still in shock.

“No, I’m not,” she said, sliding her mouth back down onto his throbbing cock after she spoke.

“Yes, you are!” he said.

“No, Paul, I’m not!” she said firmly, slipping her mouth onto his cock again and resuming the blowjob she was giving him.

Paul was totally and utterly confused, but he was also totally and utterly aroused.  He knew what was happening shouldn’t be happening, but there was no way he was going to stop it.  His sister, as it turned out, was just as good at sucking dick as the porn actress was, and she was showing him.  So he decided to do nothing but sit there and watch, letting her suck his dick as much as she wanted.

Penny slid her mouth down onto his cock, working more and more of it into her mouth until she had all of it.  She moved her hand out of the way and rubbed his balls through his jeans as she slid her wet, sucking mouth up and down his rock-hard shaft over and over again.  She’d slid her mouth up his cock until just the tip was between her soft lips and then slide her mouth back down again, her lips sliding over the head of his cock and down the shaft.  She ran her tongue around his cock as she sucked it deep into her mouth, sucking on it as hard as she could.

‘Holy shit, she’s really good at sucking dick!’ Paul thought as he sat there and watched his sister working on his cock.  Her head was bobbing up and down as she slid her mouth up and down his length, his cock wet and slippery with her saliva.  She pulled her mouth up his shaft until just the head was in her mouth, then reached inside his jeans with her hand and gently pulled his balls up and out of his boxers and jeans.  Then she gripped them in her hand, squeezing and kneading them as she resumed sucking his cock.  Paul moaned as she worked on him, sliding her mouth up and down his turgid shaft while she moved her head around to twist her mouth on him just a little.

Paul suddenly had an idea, and almost without thinking he lowered his right hand down and gripped Penny’s big right breast in his hand, squeezing it firmly.  She moaned loudly around his cock as he did this, tugging on his balls to urge him on.  He began squeezing and massaging her breast, feeling the nipple get hard and poke out against the top she was wearing.  If her shirt hadn’t been so tight on her body he would have slid his hand up under her shirt and bra, but the tightness of her shirt and the way they were positioned made that next to impossible.  So he settled for gripping her breast through her clothes, which seemed to be okay with her as well.

And in the meantime the video played on, with both of them glancing at it every now and then as Penny sucked Paul’s cock while Paul squeezed and massaged her right breast.  As the video approached the part where the woman made the man cum Penny increased her actions, and Paul realized that she was trying to get him to cum at the same time as the man in the video did.  He knew she had seen this video several times before because she had watched it with him at least twice before this, and the closer they got to the cumshot scene the harder, deeper, and faster Penny sucked his cock. 

She was sucking him hard, taking his cock deep into her wet mouth with every stroke, sucking on his shaft as hard as she could.  Paul could see her cheek hollowing in with the suction she was applying, and he felt himself approaching orgasm.  He was pretty sure that Penny was going to accomplish her goal, and as the critical scene approached Paul could feel his orgasm building.  He felt his balls twitch and his cock widen, and Penny must have felt it as well as she moaned around his cock in her mouth in response.  She increased her tempo just a bit, and a few moments later it happened.

Paul groaned as he came, his cock erupting in Penny’s mouth, pulsing and pumping as it shot stream after stream of hot, thick cum into her mouth.  She squealed in delight around the throbbing cock in her mouth, gripping his balls tightly as his cock jumped and spurted in her mouth and on her tongue.  She swallowed quickly, not wanted to let any of his cum leak out, and kept her lips clamped around his cock as it pulsed in her mouth again and again.  She slid her mouth up to the head of his cock and held it there, releasing his balls from her grip to wrap her hand around the bottom of his shaft and squeeze, pushing upwards and forcing the last of his cum out of his dick and into her mouth.

“MMMMMMMMM!” she moaned around his cock, pumping the last of his cum out of his shaft.  She pulled her head back and slid her lips from his cock, keeping her mouth closed as she kissed the tip.  Then at the same time as the actress on the screen did, Paul heard Penny swallow his cum, not missing a drop.  Then she opened her mouth and engulfed his cock once more, closing her lips around the softening shaft and sucking as she dragged her lips slowly up his length, cleaning him up and swallowing the little bit of cum he had left. 

“Holy shit!” Paul said, gasping as he tried to catch his breath.  His sister gave the tip of his cock one last quick kiss before stuffing it back inside his jeans.  “I can’t believe you just did that!” he said, still in shock.

“Did what?” Penny said, tucking his cock away.

“What do you mean, ‘did what?’” he said, incredulously.  “You just gave me the best blowjob I’ve ever had and swallowed all of my cum like it was nothing!”

“No, I didn’t,” she said, pulling up his zipper and then sitting up.  She looked at him with a deadpan expression on her face, a tiny bit of his cum still in the corner of her mouth.

“Yes, you did!” he said, looking at her.

“No, Paul, I didn’t,” she said, smoothing out her shirt.  “All we did was watch a porno on TV, and that’s it.  Nothing else happened,” she said, totally confusing him.  Then she got up from the couch, turned and walked away, headed towards her room.  Paul watched her go in amazement, but through his amazement he still noticed that his twin sister had one hell of an ass as well as a great pair of tits.  When she got to the entrance to the room she stopped and turned, looking back at him as she spoke.

“And if you’re a really good boy then maybe you’ll get lucky and nothing will happen again tomorrow night,” she said.  Then she turned and left, leaving Paul sitting on the couch wondering what the hell had just happened.

And looking forward to tomorrow night. 

Fini.
