Fiance’s sister again [MF][Cheating]

I know I am going to get hated on again for cheating, but I need to tell someone. I shared the story of how I hooked up with my future sister in law, Mary, when I stayed with her during a work trip. Well she came to visit her family.

I had to pick her up from the airport, which is quite a long way away. My fiance has no idea I hooked up with her sister and neither does anyone else. So it is safe to say I was pretty nervous after our affair, during my stay with her. We hadn’t really talked about anything, but about the fact we wouldn’t tell anyone.

I met her at the luggage claim and after an awkward hello and welcome, I brought her luggage to my car, while she went to the bathroom. I picked her up at the airport entrance and we started the two hour drive back to where my fiance, her family and I live.

I knew I wanted to talk to her about our affair, but didn’t know how. Any thought about talking however died, when Mary took off her jacket and hiked up her black dress. She was not wearing panties, which, as she let me know, she had removed in the airport bathroom in preparation for our drive back.

While I was driving she started to very distinctively masturbate and moan beside me. With an occasional rub of my cock through my pants. My attention was split and in a relatively secluded piece of forest I turned and followed one of the little forest roads, till we were out of sight.

I leaned over and pulled her dress aside to get access to her breasts. I started to suck on and massage her breasts with one hand and my mouth, while rubbing her clit with the other. Mary was already wet through all the work she had done before. So it was no wonder she climaxed already after only a little bit of rubbing and fingering.

Mary pushed me back and leaned over to free my cock, when I leaned back, she started to suck me off, despite her hating giving blowjobs. While she kept jerking and sucking my erection, I reached over her hip and kept masturbating and fingering her snatch.

The way we were positioned was not the most comfortable one. Luckily I drive a big car, with two rear benches, the backrests of whom can be lowered to form an even surface. So we moved to the bench in the middle of the car and I laid down and she got on top of me. I wanted to take out a condom, but she told me it wasn’t necessary, she was still on the pill.

Mary started riding me like that. She was just as tight as I remembered. With access to her boobs I started to massage them and her clit. We fucked like that until she orgasmed once again. She turned around and continued to ride me reverse cow-girl style until I was nearing my finish.

I moved out from under her and took a minute to rest. Mary laid back on the bench and I got on top of her continuing to fuck her like that. I kept continuing to rub her clit and breasts though, to give her more stimulation. Me being taller than Mary however led to me banging my head on the car ceiling a few times. Mary just smiled about my yelps everytime I hit my head and turned around to kneel on all fours. I leaned over her completely and fucked her doggystyle hard and fast until she was moaning loudly underneath me.

I would’ve liked to last longer and give her another orgasm, but it was too much. My groaning and grunting told Mary I was about to cum. She urged me to shoot it all into her. And I don’t think I could’ve pulled out anyway.

Spent like that we rested a while and got us presentable again. It was safe to say the affair was not over.

She is still in town by the way.

  1. Wish i had a sister in law like that! So hot the way she told you a condom wasnt necessary and urged you to explode inside her.

  2. Thats it!! Got no regreds about this … Most women don’t understand that we men can fuck without feeling just FUCK. She is doing that only because she want to feel pretty and stronger compare to her sister, but who cares YOU get her pussy :)!!
    Good job bro keep doing it!
