Ah OK, I don't call it 'sexual orientation' (sexual orientation, it's homo or hetero), maybe 'sexual preference'...
Your best friend's mother ? What do you mean ? (maybe in PM).
My real interest for BDSM dates from internet (90's). It has always been virtual.
Beleave it or not this is a true story. My friend was a kind of naughty, he liked to play very special games.
One beutiful day he wanted to play "cock sucking games". We took turns to laying on a sawhorse,
like a logg, front down, the other sat under and sucking the cock.
Just as we played his mother showed up and caught us in the act.
She was not so very happy! She said: Now I am gonna trash your bottoms right here, naked as you are.
She didn´t, but I felt a very strange feeling of desire to let her spank me. She was very beutiful.
My friend got very servered punished, he told me so the next day. He had an elderly sister,
now when I think back, I think she had teached him.
It doesn´t make sence otherwise, we were so young. I don´t think he found out it by himself.
