Had this with my ex and his ex, hahaha. He needed a place to crash, we let him stay with us a few days. He spent a lot of time walking around in underwear, half hard, and I caught my ex eyeing it a lot. I had always known he was a good fuck, and got the feel he was better than me. It hadn't turned me on until then, though
Long story short, my ex invited him to bed with us one night, whether I liked it or not, and I figured we were having a threeway. No such luck, but waking up to my man getting fucked HARD was one of the hottest things I've experienced, as was licking cum from his ass! We kept it up for a few weeks, usually me in his exes undies, not allowed to touch, waiting to suck a load from my mans ass, then being sent to the bathroom to wank alone while they cuddled. Haven't had anything comparable since, would love the situation again though
