She knows how to have fun
Male and Female
“Your wife’s friend only agreed to stroke your cock, if she was allowed to beat your balls. Hopefully it was worth the risk…”
Edge her. Then fuck her face. She’ll be more enthusiastic than you’ve ever seen her. Especially if you mention she can have a ruined orgasm after.
You’re gonna cum? Are you close? Oh too bad…did I just ruin an orgasm for you? Poor thing.
