Watching Cassy get enslaved sounds like good motivation for the rest of the girls...

The host stepped away from Sarah, but not before giving her adorable tits another good squeeze. The tits certainly weren't small, but he had plans to make them quite a bit bigger. After all, he wasn't worried about the girls getting a back-pain, since they were going to spend most of their lives on all fours from now on.

With a sadistic smile, he pulled himself out of his reverie and looked back to one of the hidden cameras. "Now that we've all gotten a good view of the birthday-bitches, it's time for them to give us a good show. But before we continue with the birthday games, let's check in with the Bitch inside the Losers' Lounge. After all, we want to make sure that the rest of this fuckmeat is as motivated as they can be, so let's show them the consequences of losing!"

On his signal, the two-way mirror turned see-through again at the same time as the large screen inside the party room sprung to life. The girls left on the couch almost jumped insitinctively as the speakers around the room blared out Cassy's gagged screams from inside the losers' lounge in dolby surround. The girls were forced to watch as Cassy was dragged over to one of the pieces of bondage furniture, a bondage horse, which consisted of a narrow wooden plank held up horizontally on four wooden legs. In the middle of the plank, two large latex dildoes protruded from the wood, which were waiting to impale poor little Cassy. The rapists had checked out all the girls' pussies during the orgy, and since they hadn't found any trace of a hymen in Cassy's cunt, she was going to get the full experience, rather than getting the virgin-treatment, which would have spared her the dildo up her cunt. As it was, the two rapists lifted the squealing and squirming girl up onto the contraption. They barely paused to slap a small amount of lube onto the dildoes before enjoying the experience of pulling the teenager's helpless, squirming body onto the horse, fully impaling her two primary fuckholes in the process.

Cassy screamed into a gag, a sound that echoed through the party-room, as her pussy and ass convulsed around the enormous intruders inside her, then squealed even louder when the dildoes buzzed to life, vibrating viciously inside her. The two men trussed Cassy up by her wrists, letting them dangle from the ceiling by a taut chain, then grabbed her feet and bent her legs by the knee and tied her ankles to the back of the bondage horse. Finally, they grabbed two short chains on the side of the horse and clipped them to Cassy's bondage belt, forcing her body even more onto the dildoes and making it impossible for her to inch back up even a little. Presented as she was, with her body helplessly spread, with the dildoes violating her cunt and ass, and with her clit rubbing against the narrow wood, she was ready for the first phase of her induction into slavery.

The other girls had to watch the entire ordeal, whenever one of them tried to turn away, or closed her eyes, she was quickly rewarded with the cattle-prods. The entire gaggle of bound-and-gagged girls had to witness the process of one of their best friends being welcomed into her new life of permanent sexual servitude as the two rapists locked in with the petite blonde bitch took two bullwhips from a shelf stacked with bondage implements and began to rhythmically slash the leather whips across Cassy's body. Welt by welt, her ass, her back, her tummy and even her tits were turned pink as the rapists proved themselves as experts with the whip, knowing exactly where to hit her to cause pain but not serious damage. The whips didn't even draw blood, as they had been specifically crafted from soft leather to tenderize girl-flesh. All the while, Cassy screamed and pleaded into her gag, sweat running down her body as she was brutally violated, both by the latex intruders inside her fuck-holes as well as by the criss-cross pattern of a proper lashing.
