This is a true story about my gf from a few years ago, I’ve changed names and some other small stuff but ages and physical descriptions are true for the time.
A couple months into our relationship, my [20M] gf[19F] Jess and her whole family went on a family vacation for a couple weeks. We were still in our honeymoon phase and would fuck as often as we could. These two weeks would be the longest we’d have gone without fucking since we started dating. Jess had a very petite figure. She was about 5’3” with a tight ass and small but perky boobs. Her face was beautiful though, and her best feature was definitely her plump lips which she loved to wrap around my dick. Jess had an older sister Nina [24F]. Nina looked a lot like Jess but she was slightly taller and had a thicker curvier figure. I’ve always found Jess’ face more sexy but even though Nina had a killer body, she had a cute innocent face. I’d be lying if I said I’d never fantasized about her, even while fucking Jess.
During their vacation Jess would keep me updated with pictures of her changing in and out of her swimsuit as well as in the hotel shower. She’d tell me how horny she was, how much she missed me, and even sent a couple videos of her playing with herself. When they got back I thought it’d be a good idea to surprise her at her home with a bouquet of flowers, she loved that. I greeted her family including giving Nina a hug. While I was there they remembered they had left the family dog with a relative that lived about a half hour away. Nina quickly volunteered to drive to pick him up, and Jess tugged on my arm to go with them.
They had a late flight and by the time we were driving to pick up the dog the sun had been set for a while. That drive was fairly uneventful. Except that Jess had suggested the two of us sit in the backseat together. The girls told me about their trip and would laugh at stories about their time there. All while this was happening Jess would reach her hand over and gently rub on my dick. 2 weeks of no sex and this got me hard very quickly and I could feel precum begin to come out. I was nervous that Nina would see so I’d gently move her hand aside while we all talked… but it always found its way back.
We eventually picked up the dog who found his spot in the passenger seat. When Nina began to drive home Jess loudly announced “I’m pretty tired I’m gonna try to nap on the way back” and she put her feet up on the car seat and laid her head down on my lap. At this point the car wasn’t lit very well and Nina and I didn’t continue to talk either. The only sound was the radio that Nina had left on rather quietly. I assumed Jess did actually fall asleep when all of a sudden I feel her hand begin to squeeze onto my penis again. Her head was resting on my lap and my bulge grew right in front of her face. I played it cool pretending to just stare out the window in case Nina looked back. Pretty soon I could feel Jess’ gentle kisses over my pants, and then her tongue begin to rub on the bulge. She got me so hard from teasing me. Then in an instant she unbuttoned my pants and pulled out my hard cock and slipped the head in her mouth.
I jumped a bit. I didn’t expect her to do that, not with her sister sitting right there. But I continued to try and play cool. But her tongue swirling around the head of my penis felt so good. Then a moment later she forced her head forward and took my dick in as deep as she could. She was always good at that. She began to move her head back and forth taking my dick in and out. I had to hold in my moans, but I also noticed that as she sucked she’d let out quiet slurping noises. I looked to Nina, worried that she could hear, but nothing she didn’t turn she looked very focused on the road. I kept my focus on her as Jess tried to throat me quietly. I could hardly make it out but I think I noticed Nina’s eyes move to look back at us through the rear view mirror. The thought of Jess’ hot sister watching her suck me off turned me on so much. And I know I got harder while in her mouth.
Unfortunately we made it back before I could finish. As we pulled into the driveway Jess slipped my wet dick back into my pants and wiped her mouth. I. Had to readjust to hide my boner and tried to subtly re zip and button my pants as I got out of the car. I hung around for a bit after that they told more stories and unpacked some stuff. Eventually I had to go. I was about to let myself out when my girlfriend followed and again announced “ok I’ll walk you to your car” as she purposely rubbed against my dick. We went to my car and she let herself into my passenger seat while I got in the drivers seat. The moment the doors closed she said “take your dick out again I want to swallow your cum” no objections from me. I pulled my pants down a bit while she sat on her knees on the passenger seat. She leaned over and immediately started slobbering over it and slurping it up while she stroked it with one hand. There wasn’t any need to be quiet anymore. I put one hand on her tight little ass and watched her head bop up and down. All while thinking about her older sister earlier watching us. She didn’t stop until I came into her throat. She licked my dick clean, said Thankyou for the flowers and kissed me good bye.
We still bring this up some times, she says there’s no way Nina could have known, and that they’ve never talked about it. But I like to imagine she was sitting in the drivers seat watching through the rear view with one hand rubbing herself, maybe even thinking about joining.
