You come home one night and notice a few cars outside you dont recognize. You go in and hear your wife moaning from the bedroom. You head back there and discover a shocking sight. Your wife is in bed on her back, nude, legs up, and a strange man is between her legs thrusting into her. She yelps and groans each time his hips push his cock into her. But there's more. Three more men are in your bedroom too, all naked or bottomless, their cocks visible and erect. As if patiently taking turns using your wife's cunt, one after another after another...
You cant help yourself, and take off your shoes, undo your belt, take off your pants, underwear, and then get onto the bed next to her. You lay face down so your little penis presses against the bed, to get that selfish sensation.
You lean over to kiss her. She kisses you back. As she fucks this other man whom you dont know. She breaks it off, and then whispers, "Husband, I need his cum inside me. I need it from all of them. Because your little shrinking balls cant make enough for me. Not anymore. Perhaps they never could. We both know it. But I do want you to watch. And do anything our generous guests need of you. Like a good little boy. Which I know you know how to do. I've seen the porn you play with yourself with."
You nod. And then try to get comfortable as the other man continues fucking your loving wife.
