I had a friend who had a sister who was interested in me; obviously I knew her and her entire family to some degree. She was very shy, and one day she invited me over for dinner, her brother and another older sister were there.
My friend, her brother, laughed and said Becky was so excited, he was making fun of me, but then settled down and said she's really going out on a limb here, she is very shy and he was surprised she was doing this.
So, I go over, my friend is there, we all are having drinks, her sister had some weirdo boyfriend over, then we sat down to eat. Becky had went all out, even going so far as to decorate her dining room very nicely.
Her sister (who lived there too) was upstairs with her boyfriend, we are in the middle of dinner, and Becky is being cheerful, nice to me... then I heard loud knocks... we all looked around, it would get loud stop, then slow, then fast as hell!
We all know what is going on, then her sister starts to moan and scream!
And if that was not enough, she started talking dirty... 'don't stop you f'ker', 'are you a man, f'ker?'!
Well, we all laughed it off initially, but then Becky excused herself, I could hear her crying in the living room. Her brother felt bad, I felt bad, Becky was embarrassed, but her sister felt good I guess. Nothing ever happened between us.
