He suggested that you'd like it if I watched you get fucked. You had already been made very wet by our previous playfulness, and the prospect of being such a slut in front of me was too much for you to resist. You asked if I'm okay with that and were not at all surprised at how quickly I said yes. You pulled John into the bedroom, while I followed.
The two of you tore each other's clothing off while I watch. He started by having you suck him for a while, so I'd have a good show, then he laid you down and enters you, fucking rhythmically, for a long time. You moaned, grunted, and finally shouted in orgasm, but he didn't stop until you told him you've had enough. He pulled out and looks at me. I was greatly enjoying this private porn show. He then said something that floors you. He asked if I want a taste of him. I couldn't control myself and almost jumped to my knees in front of him, putting as much of his cock as I could in his mouth. You reached over to me and opened my pants, jerking on my cock. I was sucking and licking him over and over, just overwhelmed with the ecstasy of having dick in my mouth, tasting and swallowing his precum.
After an unknown time of this, he told me to get my clothes off--he had something for me. I was naked instantly. You asked if you could play, too, and John was fine with that. You got on all fours and had me inside your pussy. John got behind me, his wet cock rubbing in my ass crack. We both knew what he wanted to do with me--use me like he uses you. Slowly, he forced himself into me. It hurt--I hadn't had anything there in a long time, certainly not a dick like his. But he was inside me soon enough and pumping in me. It was all to much for me and I came immediately inside you, but you had naughty thoughts--you wanted me to be totally overloaded and move around to start jerking my softening cock.
After I came, John stayed in me and I drop from my knees to my hands and knees. Then he started working my ass with his cock, over and over, and you worked my incredibly sensitive cock with your hands and mouth, driving me crazy--but I couldn't move to get away, I was trapped by John's dick in my ass, making me his pleasure toy. Finally, he shot his load inside me. I was fucked, thoroughly fucked by him just as you have been.
