Reluctantly, yes.

Here I was saying my wife wasn't allowed to fuck another man, but she was right, I'd had sex with another woman, and the fact that she'd joined in afterward was kind of irrelevant really. Besides, she was upset and I always hated it when she was unhappy. As I sat there reconsidering, Gina 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. "You know I hope I can keep playing with this... if Melanie continues to let you..." Gina whispered in my ear as she began pulling my foreskin up and over the head of my cock, 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 lose."
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 rolled back over and 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.
