I (30m) fingered my (27f) sister-in-law to completion next to my sleeping wife

This was a while ago now, but my SIL was always a bit extra friendly with me and then one day we took it further..

She’s 27 and on all accounts I’d say attractive

It was a weekend we all stayed together at a large shared AirBnb, and had all been drinking some wine. My wife and I shared a room and she had opted to sleep in the extra bed in our room instead of the couch.

After we all stayed up and hung out my wife and I went to bed, my wife falling asleep almost instantly. I laid in bed and eventually found myself feeling a bit horny. I got ready for bed and laid back down, beginning to stroke my cock a bit by myself next to my sleeping wife.

That’s when I noticed that my SIL was in the bed next to us. She’d walked in when I didn’t notice and got into bed. I froze, but I heard some soft breathing, faster than normal and could see her hand under the covers slowly moving, she was touching herself.

So, I continued stroking my cock, hearing her continuing a little faster. And slide the covers down. I could hear how wet she was in the darkness. I decided to take a chance, standing and walking over, and she grabbed my wrist as I got close, pulling my hand down.

I felt the heat from her pussy and my two fingers pressed into her slowly, I began fingering her and with my left hand covered her mouth gently. She immediately began to breathe faster and move her hips with my hand. She reached up and grabbed my cock, stroking me fast.

I sped up and eventually, my hand covered in her wetness, she quivered and slowed, and I removed my hand. She held my cock tightly and I could feel myself pulsing…

I think about it a lot and, though it wasn’t something I ever planned on, I’m eager to see her again. She’s always extra nice to me when I’m around and her and my wife are of course, extremely close.
