Love a nice amatuer anon set up. Voyuer. Titilating watching strangers get down. That popper hit, instant rush makes you lose your inhibitions for awhile and just go for it.
I love the ass to mouth!! I always suck a cock clean after a guy fucks me. Some guys are very sensitive after they cum so I learned to just hold their cock in my mouth until they go soft. For me, it's a sign of respect to the Top, letting him know that I appreciate him fucking me.
