Our very private sex fun with a 2nd guy, a guy we do this with regularly has improved our sex life immensely. We are adults, our friend us an adult. We always do this together.
We don't use terms like this but...she gets the hell fucked out of her from him and me when he visits. She gets turned on like crazy. She obviously enjoys the sex, she likes the kissing, oral, getting split roasted and everything else that happens.
She's horny as fuck for days after so we have a lot of sex after he's been with us.
There's no humiliation, nothing negative, she's never said anything about his(bigger) dick other than it feels good.
We do this together because we both have fun.
