A deal made

Her mouth pulled back, just as her fist hit my balls! What should have been the best orgasm of my life was stopped in its tracks as pain erupted in my groin and shot up to my stomach. My already non-existent appetite got crushed even further as I started feeling nauseous.

I had come across ballbusting porn in the past and it was somewhat enticing to me, but I can't say this was a good introduction to the kink. I managed to mostly hide what was going on by coughing, pretending I choked on my drink. But it couldn't have been my best look of the evening, as Lily looked a little confused.

"You okay?" She asked, eyebrows raised.

"Yeah, just hard to concentrate right now."

"Okay." She settled back down and took a sip of her drink. "I really thought you were gonna cum there, but seeing as Monica is still going at it I guess you managed to hold on."

She seemed to trust Monica. And with Monica holding up her end of the deal, I guess I would have to keep going. A prospect far less pleasant after being punched in the balls.
