Fiancee’s sister is doing laundry [MF][Cheating]

Short summary of my situation: I stayed with my fiance’s little sister, Mary, during a work trip. While drunk we started an affair, that lasted for the time I spent there. We agreed not to tell anyone.

However she came here for an extended stay to visit her family. We never discussed what we would do, if we saw again. As no one else could make the two hour drive to the airport to pick Mary up, I went to pick her up alone. We ended up fucking in my car in a secluded piece of wood on the way back. Following that we talked a little about us and where this all was going, we agreed it was just very great sex, but without emotional attachment.

My fiancee wasn’t home and Mary came over to wash some clothes. I am between work projects so I don’t have to be in the office, outside of doing work on the daily mail addressed to me. So I was home when Mary came over. I helped her getting her laundry ready and into the machine. As her big sister was at work, Mary decided to take the opportunity and have some fun.

She knelt down in front of me and started jerking me off. Mary doesn’t like giving head, but she knows I like it, so she made an effort, but I always can feel her not liking it, in the hesitation in her movements. I enjoyed myself as much as possible, which was plentiful nonetheless. When I was hard, Mary stood up and took of her skirt and panties.

I bent her over the washing machine and started eating her pussy. When she was moaning in enjoyment, I started rubbing her clit until she was wet. Mary asked for more and I stood up and started fucking her, while bent over. I lifted up her leg and put it on the machine in front of her. That was to get better access to her clit. While I was fucking her, I also rubbed her clit. The machine spinning and rumbling away under her Mary climaxed like that. The cliche about the vibrations of the washing machine intensifying sex seem to be true.

Mary laid down on the washing machine on her stomach. I pulled her back until her pussy was on the edge of the machine’s top. I held her legs up by her knees and fucked her, while she was placed like that on the machine. I fucked her as hard as I could and she moaned loudly. She turned around onto her back and started to play with her tits and breasts. She seemed ready to orgasm again and I was not wrong, shuddering she finished again.

Wanting to pause for a bit, she pushed me away, but knelt down in front of me and took her tits, by pulling the collar of her t-shirt down. While she rubbed along my shaft with her tits, she bowed down her head and licked my tip. This went on for a little while and she was ready again. I told her that I was close myself and she answered smiling, last round.

She sat down on top of the machine and locked her legs behind me, while I fucked her. I was massaging her breasts and her exposed clit. She told me, I should hold on, so we could come together. So I did my best to hold on. Mary helped me by playing with herself too, so she would finish faster. Just when I was about to cum, Mary shuddered in climax. I reacted by grabbing her in a tight hug, and as I already knew she took the pill and she liked me to come inside, Mary had actively insisted I do so, whenever I tried to pull out, I gave her a creampie.

After that we cleaned up, had drinks and welcomed my fiancee, when she returned home, delighted to meet her little sister.
