Peoples expressions when having an orgasm

Kind of a tough angle for a good view when my wife used to sit on my face , but what I remember was a look of total bliss . Best view was when she was riding me cowgirl , also she would get wild and vocal and roll her eyes . That was my favorite . Me , I have no idea . When our sone was little it was amazing how quiet we could be , after he moved out we tended to become a bit more vocal .
