I've been lucky enough to run across a few wives that cum best that way. 🙂
A nurse here in San Diego, is fun, but kinda quiet through oral, and traditional intercourse...
but once I get to her backdoor
(it would be unthinkable to her that I would not address that, on every, single visit)
she absolutely comes to life, moaning and screaming encouragement. It's very sexy!
Don't get me wrong: She likes the other stuff...but she's also mostly waiting to feel her ass full of cock.
