My cock thinks so.

"You want me to let you fuck Dan?" I asked, incredulous. "You can't be serious."
"Well, yes I am. Like Gina said, you've fucked her, it's only fair I get to try Dan's cock."
"But, you've had sex with Gina too."
"Yes, but only because you'd already been with her in the first place. Besides, you like the idea anyway. I can tell.
I was about to object but my eyes followed Melanie's gaze.
To my shock, my cock was hard again. The girls had drained it numerous times, and I'd thought I'd be out of action for the rest of the night, but it was as hard as it had been earlier.
Gina began laughing at my predicament, and I guess she was right. Here I was saying my wife wasn't allowed to fuck another man, but my body was betraying me. She leaned over and ran her fingers gently up and down my shaft, and then licked her thumb and began rubbing it against the head of my cock. She was pulling my foreskin up and over, and with her thumb firmly on the end my foreskin swallowed it too. The feeling was exquisite, something I'd never felt before, as if she was masturbating me from the inside out.
Gina lowered her head to between my legs. "Go on, let her. She probably will anyway now, so you've got nothing to loose."
I was having trouble thinking straight. Lust was overruling anything else, and Gina began licking her lips, her head between my legs.
"Go on. Let her, and I'll..."
"Okay, baby," I interrupted her, "you can have sex with Dan."
Gina's tongue shot out the moment I agreed, but the feeling wasn't what I was expecting. Instead of the familiar sensation of a tongue against my cock, I was surprised at the sudden wet, hot, and extremely pleasant feel of it caressing my arsehole. Gina vigorously stroked my erect shaft as she worked her tongue into me, and my wife kissed me hard before jumping up and riding my face. The combined sensations overwhelmed me and I managed to orgasm again, though this time without cumming, so I stayed hard, and horny while thinking about Melanie riding Dan.
