She gets sandwiched

Boss approached Nicole menacingly. You can tell she was getting more and more excited with each step he took towards her. As soon as he was just a foot behind her, she began to pull out of a whimpering Miranda, but Boss stopped her, keeping her looking forward.

With the gigantic strap-on Nicole was wearing still in Miranda's ass, he pushed Nicole forward, impaling Miranda even more. "No one said you had to stop what you were doing to the other bitch," he growled. Nicole looked back and smirked at his statement, resuming her sawing back and forth into Miranda's ass. However, her smile was short lived, as Boss lined up his cock at the entrance of Nicole's own asshole. He grabbed a fistful of her blonde hair and pulled back hard as he thrust even harder into your girlfriend's ass.

"FUCK YEAH," Nicole screamed, lust completely taken over. At this point, she has stopped moving her hips on her own. Boss' thrusts were enough to not only move Nicole back and forth, but a increasingly tortured Miranda as well. "Harder!" Nicole screamed, reveling in not only the approaching orgasm she about to get, but the pain it was causing Miranda.

"AGHH!" Miranda shouted. You take a closer look to see that her predicament hasn't gotten any easier with Nicole sharing the pounding now. In addition to her sore ass, her nipples were still being stretched as she was being mercilessly fucked. The scream just egged the other two on.

"Give me the remote of the shock dildo, slut," commanded Boss. As Nicole dutifully obliged, Miranda heard and started pleading again.

"No, no, no, please, just---OH WHAT THE FUCK!" Miranda face made such a drastic change of surprise and shock (pun intended) as Boss turned the dial delivering an unspecified shock to the dildo in Miranda's pussy. Her spasms causes her to move up and down (in addition to the continuing back and forth fro the fucking), pulling her nipples even more. If she was getting tired from the poundings, this woke her up!

"Do it again, I'm so close!" Nicole clamored. She was clearly turned on by the sight of what happened. She was holding on the the shoulders of Miranda, essentially 'riding' her spasm. After what she transpired, she wanted to see more so she reached back and tried to take the dial from Boss--a bold move to say the least.

Boss slapped her hand away. "You are enjoying this way to much, whore. We ain't equals, don't try and take things from me," he said menacingly. With that he took a piece of remaining rope in the stall and tied Nicole's hands behind her back. "You're just a hole, remember that." He picked up the dial with one hand, and resumed pulling Nicole's hair with other, continuing his barbaric fucking. "Screws, if there's another shock dildo, put one up this girl's cunt too!"

If the turn of events caused any distress to Nicole, she didn't show it. Instead, it seemed like she was even more turned on. "That's right, treat me like a slut," she whispered. "Treat me like the biggest slut there is."

Boss was getting close to cumming, and the others could sense it. Those that weren't preoccupied with Sarah were lining up waiting their turn for Nicole (and by default, Miranda).
