I was so excited by the group of young wives with beautiful butts sticking out in tight pants! I joined a yoga class and I was the only man there! When I looked around, I saw a lot of young wives in tight pants with their butts accentuated in yoga poses, and it was just too erotic! In that kind of environment... I got a huge erection! Of course, if I got an erection, I was found out and had to make a fool of myself...
