Wrong room (got fucked)
Last week my husband and I were out of town visiting an old friend of mine. She's a single mom, and we stayed at her house with her teenage son. A small group of us met up and went out drinking and we were all pretty wasted. When we got back to the house we went straight to bed. My husband passed out in minutes, as did I.
My recollection is a bit foggy, but I recall going to the bathroom to pee in the middle of the night. I then tried to make my way back to the bedroom in total darkness and flopped back on the bed, still reeling from the booze. I felt some hands move down my ass and try to slip between my legs to touch my pussy, and I figured it was just my husband being horny in his sleep (he does that sometimes). I was on my side, back turned, and we were spooning. I lifted up my leg to get fingered, since it felt nice, and pretty soon the fingers were replaced by a hard dick. I quietly let myself get fucked and just lay back and let him finish inside me. It felt nice.
I then got grabbed by the arm and led down the hall to another room. At that point I realized that after peeing I had accidentally gone into my friend's son's room, not the one in which my husband and I were staying in. I had just fucked my friend's son. He led me back to my room, where my husband was stone cold asleep.
The next morning I was still pretty hung over, and didn't say a word. Neither did my friend's son. Some things are better kept as secret.
