I Took The Cock

48 yo married but getting blown by a bi married friend for a number of years now. The back story is irrelevant.
He's been asking for years if he could fuck me. I've always said no but have allowed him to jerk off on my ass after he's taken my load.
This morning was no different, he sucked me, swallowed and I was then on my stomach while he jerked off with his cockhead touching my hole.
Something in me switched and I told him if he had lube, he could try it. We'll, he did, lubed me and him and jerked off pushing the tip in me and POP.. The tip goes in, It hurt, a lot. He told me tighten, hold it and release, that hurt too but as I released, he pushed in a little more. A couple more times of this and he said he was in all the way. Yeah, I could feel that for sure. Then he told me to push out, I did and he pulled out about half way.
Take a deep breath. I did, he slowly.pushed back in. Eyes watering, seering pain but he kept pouring more and more lube and I started getting the push, relax, breath and take it rhythm and soon, still hurt like a mother fucker, I was getting my first ass fuck, losing my virginity and hating it all the way through. I suppose it was a way of me thanking him for all the blowjobs over the years and I did actually like the pulsing of his cock as he was cumming in me.
He softened and to be honest, the feeling of him slowly slipping out of me caused spontaneous orgasmic feeling and I came from that. I laid still, in pain, eyes watering as he cleaned me and him. He promised I'd never have to do that again. He was satisfied.
So here I am, 6 hours later, 2 showers and 3 pair of underwear into it, sitting on the couch hurting and wondering how the fuck am I going to hide my pain from my wife when she gets home in a couple hours...
