I was caught post-cum some years back by my brother in law. I had been living with them for about a month when they moved into a new house. I was bartending at the time and got off early one weekday afternoon. About 5 or 6 people went to Garcia's to get some drinks and food. A couple of the girls that went were hot ( I ended up dating one of them and sleeping with a couple others thereafter
)
Anyway, I had a couple of huge margaritas and ended up finishing my future girlfriend's as well as she was quite petite. I got home failry early in the afternoon/evening- around 4 or 5. Nobody was home and I was very horny being tipsy and flirting with the other girls. I went to my room, shut the door, put on some porn and proceeded to stroke. What I didn't realize was just how buzzed I was. After cumming, I passed out in my bed....cock in hand and cum still squirted across my chest.
My sis/bro-in-law had a couple of cats and one of them slept in my room quite a bit. My bro-in-law got home and eventually was wondering where the cat was. He ended up knocking on my door to look for her and since he didn't hear a response, he opned the door. Right then I hazily woke up and saw him take one step in and realize what he walked in on. He turned right around and walked out.
The funny part about it is that happened about 10 years ago. We never spoke about it and I assumed he probably told my sister as...well....they were married and married couples tell each other everything, right? About a year ago, my sis, bro-in-law, ex and myself went out to a blues bar and got fairly hammered for my bday. after, we went back to my place and proceeded to bs about who knows what. All I know is somehow I brought up that time he walked in and lo and behold, found out he never said a word to my sis! Needless to say, I spilled the beans on myself!!
