I've grown up in a prudish family were nudity, sexuality, masturbation were so taboo! We were changing in stalls when at the public pool. Never undressing while on of us were in the same room.
my brother and i shared a bedroom for 8 years and never saw him naked. He was packing a lot and i was curious about what he looks like down there. Then, at 30 he asked me to show him how to play raquetball. Our locker room were far from one of the other. I went showering in the communal shower, he wasn't there. I then saw him in the spa. He saud Hey won't you come in the spa? I went there removed my towel and sit. He then said WOW! i didn't know you were as big as i am. I though you were small
i was in shock of him commenting my cock lol
