"It's too beautiful."

I'm certain that S's favorite position is reverse cowgirl.  No matter how long he's lasting, when I flip into this position and my ass starts pounding down on him, he always wants to come so quickly.  In turn, it turns me on so much that something I can do makes him want to come so fast.  It's too much for him, he doesn't want it to end, I pull off of him...  He mutters to himself that "it's too beautiful."  I melt.  After only a moment, he's whimpering, begging me to to get back on him.  I love him in this state.
