How did you feel . . .?
I said that the topic has reminded me of such a similar thing that happened in those memorable days.
To me it is unheard of and completely unimaginable that somebody will go and eavesdrop on his dad and mom doing the thing. What does he/she want to hear.
Satan don fall for gutter, marcham, marcham.
I remember very well in my University days in the late 80s we use to eavesdrop and even watch each other a lot while doing the thing. We are four in each room and whoever has a girlfriend that will spend the night, the only condition for others to go on 'exile' sleep outside was that the light must be on so that they can watch the action for a while.
We enjoyed it so much and the act became so popular in the hostel. Nobody was exempted even me, they watched me when it was my turn to send them on exile.
Weird, weird, weird, weird, weird, weird some people will say, but it was great fun then.
