Me and my wife had started sharing in our early 30s, but not a lot, on holiday, special occasions, wasn't a regular thing. It all started from us talking dirty during sex, and that was mostly all it was.

When we fucked she'd go wild talking about other guys fucking her, what she'd do to them. How she wanted to fuck as many as possible, wanted to fuck strangers she'd just met, let them fuck her face, her arse, anything. Sometimes even women she wanted to fuck. The strangers, hook ups, cheating was a big turn on for her though.

We're both in our 40s now. She is petite, tight ass from years of yoga, perky tits, she's pretty shy and reserved when you first meet. Not when your fingers on her clit though. More and more she'd talk dirty about meeting strangers for sex. I loved it, and begged her to do it. I'd jerk myself off watching cuckold porn imagining it was her. When I fucked her I always made her say she'd do it, "tell me you're going to fuck some guy at work" "yes, yes fuck"

One day I get home from work late at night, but I had called earlier and said it's more likely to be the early hours, but in the end must have been about 9. I come in tired, assume shes in bed and get a drink. As i sit in the kitchen I start to hear noises from upstairs.

I walk up the stairs slowly, it sounds like more than one person. I'm a bit nervous at this point but i dont shout out for some reason, wanting to see who it is. Maybe it a friend, maybe she's on the phone. I get closer to the door and it's definitely two people, one is definitely a guys voice, one my wife. Then as I take my next step I suddenly hear my wife's voice "fuck we haven't got all night, get that big cock over here again"

I froze to the spot as I heard it, maybe it was a joke, but then I hear him properly "that's it spread those legs, let me see that married pussy" I stand furious but stuck to the spot, I can feel my cock hardening as I start to hear them kiss, their bodies pushing into each other.

She let's out a massive moan as his cock must be pushing into her, "fuck yes, I've needed this" she moans, "Harder, harder" fuck I don't hear her moan like this very often. "You're so hot" "your pussy feels so tight" he moans. Who knows how long they've been fucking.

My cock is rock hard now, I'm trying to see through the crack in the door, all I can see is a blur of skin as my wife's moans get louder. My hand pulls my fat married cock out and I start to pound it furiously. All my fantasy's in one, my wife getting pounded whilst I jerk to her

She's getting fucked good, I can tell by her grunting, I jerk harder. I can just about tell she's on all fours, face pushed down. I can see her skins red and sweaty. She starts to beg him now "yes, fuck me, fuck me like my husband doesnt, please harder" fuck she's a good dirty talker. He starts to give it back "fuck I love fucking older women" he shouts. Some young stud fucking my wife, knowing she's married is nearly too much for me

He's fucking her hard now "fuck your cocks so big" "fuck" "mmmmhhhhppphh" is all she's giving now. I hear his hand slapping her arse as his grunts get louder, hear his body slapping into her. I'm pounding hard, it's a good job they're making so much noise as I'm enjoying myself.

"Fuck I need to cum" he moans, as her moaning gets louder as he must be speeding up. Nothing but grunting and shouting coming from them both. It's too much for me as I spunk all over the floor. "Fuck me, cum in me" she shouts, as he grunts hard, clearly filling her married pussy full of cum.

Post cum clarity hits hard as I realise I need to move away from the door so I'm not found here. I move slowly into the other bedroom and hide. It feels like forever as they chat before he gets up to leave, and even longer before she gets up. I wait as she goes in the bathroom before I rush downstairs, out the door, to my car, ready to pretend I'd just got home.
