Flipped roles

Usually I write about young men who are watched having sex by older men. This is a flip of that.

When the guy was a teenager he accidentally found out a friend's dad had a mistress. He blackmailed his friend's dad into letting him watch the older man have sex with his mistress. The older man had originally offered money to the young guy for his silence but the teenager countered with the watch him have sex. At first the older man was bland in his love making. But as the older man got comfortable with the younger man watching him he got more adventurous. He would hard fuck his mistress, eat her out after cumming inside of her, do 69, and anal. The young guy was not expecting to watch anal. He got a new found admiration of his friend's dad and learned a few things. The young guy watched his friend's dad several times.
