No way.

Although I didn't like my wife being upset and sure, I did want her to have pleasure, I wasn't going to let her fuck other guys. Okay, she'd let me fuck another woman, but so what? It's not 'an eye for an eye'. Women though...
"Sweetie," I started, while still figuring out what I'd say. "I'm sorry but I can't let you have sex with guys. It was your choice to let me have Gina, but that doesn't mean I have to let you in exchange."
Silence. Cold, stone-faced silence.
"If you'd like to play with Gina again though that's fine; with our without me there. Or if you like, any other women, just no guys, okay?"
Silence.
Gina rolled my wife over and kissed her. "I'd love to play with you again Melanie, it was so hot."
"Mmm, okay," my wife replied, melting into her, "but HE doesn't get to join in next time."
