Couple sex with our best friends
Sometimes my wife and I fantasise about having couple sex with our closest friends while we have sex. We talk about sharing a holiday with them. The sexual tension between us all. I whisper in her ear about how Matt (friend), gently glides his penis into her, while softly rubbing the inside of her thighs. About how I love watching her orgasm with Matt's penis deep inside her.
We've never done this before, but I love that my wife enjoys orgasming with these thoughts, while I fuck her. Unfortunately I don't think this will ever eventuate. But who knows where this might lead.
