Ms. Tyra I used to do that too! I loved flipping my man over and rubbing my clit on his boy pussy til I came. Omg his build was similar to how you described too he had such a nice round soft ass I just loved playing with it.
I have always wanted to try it again and to take it a step further and use toys/ a strap-on but as I am not experienced I believe it would be unfair for me to advertise it until I'm semi-pro status
One of my naughtiest fantasies has been to do a doubles session with another lady and drown one lucky man's body in pure ecstasy with sweet toys and two deliscious tools that will go in any hole they please...omg...ok I need to calm down now lol. Great confession/topic!
