Three (and a half)

"I'm game, babe," Billy says, "Let's see how she likes this!"

He pushes his cock all of the way into her, not caring how uncomfortable it may be for her. As it turns out, she does kind of like it (even if she won't admit it)...

She lets out a muffled yell as the shock of his cock filling her up tighter than she's ever felt causes her to have a small orgasm right there!

Kim looks into Tiffany's eyes as the orgasm passes through her. The bound woman closes her eyes out of shame, but they are **** open.

"That was a good one," Kim says, "That counts a half one. Keep it up, big man!"

Billy nods and keeps fucking Tiffany. He's getting used to how tight her hole is, slowly building up speed and rhythm. The once-strong woman loves being fucked like this, even if she wouldn't admit it.

In spite of her resolve, it's only two minutes before she has another (this time full) orgasm.

"Mmmphhhh," Tiffany cries out, her exclamation still muffled by her full lips.

"That's a real good one," Kim says with a smile, "I want to hear her next time."

She pulls the now-clean dildo from Tiffany's mouth. She tries to spit out the juice, but her mouth is quickly covered by Kim's hand.

"Spit on me again and you'll really suffer, bitch! Now tell me that you love his cock in your ass."

"I...I love his cock in my ass," Tiffany says sadly.

"Good job. Now keep it up, Billy."

Billy nods and grabs a hold of the woman's naked ass. He uses the leverage to pound her even harder. Plus, he loves squeezing her ass. It's something that she wouldn't let him do before.

About a minute of this is all it takes to drive her to orgasm yet again. She absolutely loves this...but hates that it is being done to her. Is she really meant to be their ****? No...it can't be...can it?

"Fuck- I'm cumming again," Tiffany exclaims.

"Damn right you are, bitch," Kim says, leaning in and grabbing her throat, "Keep it up. Give her another!"

Billy doesn't stop his pace. He lets go of her cheeks, but starts to spank them instead. He swats both cheeks with each thrust, accentuating each one. Tiffany moans in spite of herself.

Sure enough, she cums for the third (and a half) time thanks to Billy's dick. Did the spanking help get her off or was this just a coincidence?

"I'm cumming again! Fuck fuck fu-uck!"

Her body struggles and strains against the ropes holding her down as she cums dramatically. Her inner muscles squeeze Billy's dick. He can't hold out any longer from this strain.

"I'm gonna cum, babe," Billy says, "I'm gonna cum in this bitch's ass."

"Do it! Cum in her ass like the dirty whore she is," Kim says excitedly.

Billy grunts and unleashes a long-held-in load into Tiffany's ass. She's so caught up in her own orgasm that the disgusting thought of his seed filling up her forbidden hole doesn't occur to her. It will eventually.

(Shit- he fucked me so good,) Tiffany thinks, (I came four times! Do I love being his slut?)

"Nice job, babe," Kim says, pulling the woman back to reality, "You stay there. I'm going to make this bitch suck my strap-on before I fuck her. How does that sound?"
