Play with his nipples

"Now it's time to make those titties a little perkier, sweetie. You like having your breasts played with, Christina, don't you?" Beth was obviously taking pleasure in humiliating him.

Still burning with embarrassment, Chris didn't say anything in response. He merely looked down, unable to meet her gaze.

Beth sat Chris down on the sofa, leaned him back, and straddled him, pinning his arms down in the process. She slid the bra staps down his shoulders and pulled the black satin cups down his chest to expose his nipples. She grabbed Chris's nipples, and started pinching them and pulling them. At first she wasn't playing that hard with them, but after she got going, she started to get more ferocious, squeezing and biting them brutally. Chris started to yelp as the pain was amplified, and after one nasty bite, he cried out in pain.

"Can't have our girl disturbing the neighbors," said Sally, who otherwise seemed to be enjoying the show. She took off her soaking-wet panties and stuffed the pungent undergarment in Chris's mouth.

Despite the pain, or perhaps even because of it, Chris kept getting more and more excited. He had never thought of his nipples as being particularly sensitive, but now it was as if they were tapped right into the pleasure center in his brain. Between the sensation in his nipples and the silky material containing his privates, his cock was as hard as it had ever been. He began panting, getting closer and closer to orgasm.

Before he could gain release, Beth saw how excited he was and stopped. She reached down, grabbed his ball sac and twisted, pulling them away from his body. The sudden pain in his sensitive balls jarred him out of his reverie, and his eyes refocused again, looking up at Beth.

"Don't even think about coming without permission, Christina. You don't want to find out what happens to bad girls who have to be punished."

His mouth still filled with Sally's panties, Chris merely nodded.

Lisa was ready to move things along. "Well, I think Christina's breasts are nice and ready now." And they were. Chris's nipples were swollen much larger than they had ever been, well beyond the normal dimensions of male nipples.

Lisa handed some silicone breast forms to Beth, who slipped them onto Chris's chest, then slid the bra back into place. Chris sat there for a moment, than began to squirm.

"What's the matter, sweetie? You don't like Icy Hot on your puffy nipples?" Beth began to laugh, and the other women joined in.
