She shuddered and screamed as the rod ran over her tight asscheeks, caressing her flesh, stroking back and forth.

"Yeahhhhh!" Galvin murmured. "This is quite an ass! Gonna enjoy this!"

"Better than mine?" Robin asked. "Come on, tell me."

She strolled up to the chair and brazenly slid her hands down her legs, bending at the waist until her ass stuck up beside Jeanette's. She reached up and pulled her flared skirt over her ass, revealing her white panties and the lacy suspender straps that ran down to her stocking tops.

"Well," Galvin said, sliding his hand over Jeanette's flesh. "I think it would be better than yours, but she's carrying a few extra pounds."

"All that ice cream," Robin said, and stood up again. She went to Galvin and slid her leg up his, working her skirt out of the way. "Please, Mr. Discipline, can I fuck my boyfriend while you whip my sister?"

"Sure," Galvin said, and slid his hand over the front of his tight jeans. "I'll keep going until you tell me to stop, even if she's ready, how about that?"

"Oh, that would be great, Mr. Discipline," Robin said, and went back around to the front of her bound sister. She stood there, grinning at Jeanette as she opened the waist of her skirt and let it fall to the dirty floor. Her fingers opened her blouse just as fast, revealing her little uplift bra that only covered half her lovely tits.

"I'm gonna show you how to fuck, Jeanette," Robin said, grinning as Stan came up behind her and put his arms around her, holding her tits, stroking the twin mounds openly. "You know what Stan's doing now? He's shoving his great big cock into the crack of my ass. I love the feel of a cock in my ass. Ever had one? No, probably not, you almost freaked when Jeff Nutson fucked you, remember that? Well, we're gonna change all that."
