While visiting a friend's house, my older sister or mother accidentally saw my erect penis. She then gently gave me a blowjob, causing me to lose my virginity. (SW-179)

I went to my friend's house and unexpectedly discovered his mother's lewd behavior, with her underwear and cleavage showing, which made my penis instantly hard and erect. Unexpectedly, when my friend's mother saw my erection, she secretly and gently reached her hand towards my penis, giving me an incredibly passionate first experience.
