The first time my mother walked in on me jerking off, she didn’t freak out or anything like that. What she did do was insist that for her peace of mind, that she demonstrate how to place a condom on properly.
So she went to her room and returned with one, sat down beside me on my bed, and kind of pressed on my tummy motioning me to lean back some. I did as she asked as she proceeded to open the condom. I figured this is weird but I’ll just put it on fast and get it over with.
Well, I was wrong, it became apparent that she had every intention of putting it on me herself. I just watched as she rolled my foreskin back, and telling me that this was proper because otherwise the condom could slip off. Then she started to slip it on. She had to flip it over because she had it the wrong way, but she very easily had it run down my cock and to the base.
Well, that was all it took, that one downward motion. I was cumming in the condom as I was apologizing profusely, implying that it was part her fault because she came in at a bad time.
She just smiled and patted my tummy, and said something like “well, at least you didn’t make a mess.” She got up and left at this point, leaving me to wonder wtf just happened.
