I sat back on one leg of the sofa, recovering from the most intense orgasm of my life. Just moments earlier, I erupted inside of my girlfriend's little sister, my cum filling her 18 year old mouth and spilling out of the corners. I had watched as my girlfriend, Kim, and her sister, Katie, shared a cum-filled kiss. I felt paralyzed as I watched them grope at each other wildly, Katie fully naked and Kim wearing her usual tight cotton panties.
As they settled down into a sort of nipple sucking 69, my head cleared enough to take in the scene before me. Kim's legs were resting at a 90-degree angle on mine, her knees wide, exposing the damp crotch of her panties. I always loved the way her panties seem to be a ½ size too small, clinging to her folds and leaving just enough to the imagination to make me shudder. Her thighs are creamy white, smooth, and probably not quite thin enough for a runway model. They lead up to womanly hips that give her the hourglass silhouette. Kim still has a cute gap that I can see when she stands. Her ass is probably her best asset, at least the best one viewable with clothes. It's tight, apple shaped, and just begging to be spread.
Katie was on top of Kim, sucking on her older sister's hard nipples. Kim's areola are light brown, leading up to beautiful hard, sensitive nipples, and they form the peak of her firm B cups. Sometimes I like to alternate sucking on them for twenty minutes, getting her ready to explode at any touch. Her auburn hair was strewn behind her on the couch.
Kim's lips, glazed with Katie's pussy juice and my cum, are wrapped around Katie's right nipple. Katie's nipples are paler brown, almost a dark pink. Katie's areola are wider than Kim's, and her nipples are wider and lower, like a plateau as opposed to a hill. Her full D cups look soft as they hang in Kim's face. My girlfriend was in a personal nirvana, her hands squishing her little sister's tits in her face. Kim was practically devouring Katie's young breasts. I wonder how long she secretly harbored the desire to feast on those soft pillows?
Katie's skin is a bit darker; she obviously tans or lays out, although she lacks any tan lines. After what I've seen over the last few nights, I would believe that she lays out in her parent's lawn naked. Her flesh has that baby fat glow to it, the girlish softness that seems to trigger a wanton lust in those around her. Her ass stuck up in the air as she buried her face in Kim's tits. It was probably about the same size as Kim's, but with just a touch of sag. Almost a baby fat look, I bet her butt folds over just a tiny bit when she stands. You know, the type where you could hold a pencil underneath each cheek, but in a good way.
Katie's full lips are wrapped around Kim's left nipple, suckling like she hungers. Katie's hair is dark brown and straight, although it had a charming bed head look as it sprawled across Kim's stomach. As I lay there, my boxer briefs around my ankles and cock half-full, half-drained, time seemed to stand still. My girlfriend, fresh off catching her little 18 year-old sister sucking her boyfriend's dick, just got done tasting her barely legal pussy and sharing a hot, cum-filled kiss. Looking back, I could almost piece together a puzzle leading up to this moment.
A month ago, Kim got the idea to surprise me with the gift of porn. Not just any porn, but 2 girls and a guy porn. I took that as a good sign, of course, because what guy doesn't want to experience such Sapphic delights? She played a video of a young Asian girl babysitting for a young "couple." Pornos do what pornos do, and soon the "wife" was cumming hard on the Asian girl's face, with strings of pussy juice going from pink lips to pink lips. That part always sets Kim off. Well, that, and when I smack her face, or choke her lightly, or talk dirty to her, or smack her tits, or pound her up against a wall...
Three weeks ago, after a long week of dirty fucking, Kim started sending me dirty texts.
"I'm tweaking my nipples at work and they're poking out I think everyone can see."
"The secretary definitely stared at my tits I'm going to flash her my panties." The secretary at the doctor's office that Kim manages is a cute little Latina who dresses very sexy. Professional, but sexy. Her usual outfit, according to Kim, is a tight pencil skirt that shows off her curvy hips, a blouse that showcases her ample cleavage. Is Kim into her or just getting aroused by being an exhibitionist?
"I just bent over in front of Rita I think she saw up my skirt." Kim was getting bold.
"Don't get fired lol." I replied, half-seriously and half-jokingly.
"Mmm conference call with door closed panties around my ankles." At least the door is closed. "So wet want to see?"
"Of course, send pics!" I had no illusion that she would actually do it, but within 2 minutes, I had 5 pictures. The first was a view of pussy, her tight lips mostly closed and a little hint of dew near the bottom of her pink slit. In the second, she was pulling her lips apart with her right hand. The third picture showed her pushing 2 fingers inside. She must be really wet; usually it takes a few minutes to work a second one in. In Kim's fourth picture, her fingers were out and a little string of juice went from her fingers to her pussy. The last picture, though, was amazing. I saw her wet, sticky fingers getting licked by her pink tongue.
"So tasty, you want sum?" Of course I did! I sent her pics of my cock, now hard and throbbing. She especially loved the picture that showed some pre-cum sitting on the tip.
"mmm I want to lick that up give me a taste!" I hope she's not missing anything on her call. "Come over to the office at 6 exactly!" She texted. It was 4:30, and that last hour before I left work (early, I'm not missing an invitation like that!) seemed to last forever. Kim sent me more pictures, including her wet panties laying on the floor, a sticky spot clearly visible.
I arrived 5 minutes early. "Is Kim available?" I ask Rita, noting her curves as she walked around the counter.
"No, sir, she's on the phone, sorry. I think she will be done soon. What are you doing here so early?"
"I, uh, want to get an early start on dinner. I figured I'd meet her here. And I've told you, you don't have to call me sir!"
"Habit, I suppose. Sorry, sir, won't happen again, sir."
I laughed. "Okay, okay."
"Where are you guys going to dinner?" This small talk is going to catch me up in a lie if I don't stop thinking about sex and start thinking clearly. What I wanted to say was "I'm going to dine at Kim's juicy pussy and fuck her for desert!" But that wouldn't be very, um, polite. Or appropriate. Still, the thought crossed my mind, and I understand Kim's desire earlier to be bold. I wonder if Rita really noticed.
