I was 27 she was 25 and for a few years me and my SIL were having sex on most weekends when my wife was at work. One night I went out and got drunk and text my wife to say I was gonna stay at my mates house.

I wasn't I turned up at my SIL house at 2am. She finally opened the door in her dressing gown and a short nightie. I pushed her back inside and within seconds I was kissing her, pushed her back onto her kitchen table stripped off her clothes and went to town kissing her naked body. I slid inside of her and fucked her hard like I never had before. I flipped her over and bent her over the table and forced my cock hard into her ass. I could tell she was in a bit of pain but she never told me to stop and I was so fucking hard I don't think I could of even if she asked. Finally I managed to get deep inside of her and she let out a little moan. I slowly fucked her ass and within minutes I could feel myself pulsing inside of her firing my hot load inside her ass.

As I withdrew from her ass I could see my load sliding down towards her pussy and I did the unthinkable and put my dick back into her pussy and fucked her again.

It felt likewe had been fucking for ages but I doubt it was.

It was the first time I ever spent the night with her and wasn't the last. The thrill of waking up next to her and having sex again before I had a shower and went home was amazing. Yes I felt like a dick but she was forbidden fruit and I had to have it.
