Manfred held the chain, forcing her facedown over the chair back while the two girls grabbed her ankles and pulled them out, lashing them to the legs of the chair.

Mirabelle screamed, telling herself that she had to put up with any pain rather than submit to their perverted desires.

Manfred sat down on the floor, leaning on the chain, stretching Mirabelle over the chair back until pain shot all over the bound blonde's back and legs. He grinned and called Nichole over. The little whore slid to the floor and took Manfred's already-hardening cock into her mouth, sucking it softly while he watched Mirabelle's suffering.

William stood in front of Mirabelle, holding a thin rod. "I'm gonna whip your panties off. So we can fuck you when we want. I think Dustin's just about ready."

He lifted the rod and rubbed it over Mirabelle's trembling lips.

"Be sensible, bitch. Beg to suck cock, this sucker really hurts!"

Mirabelle shuddered, her hands at the collar, trying to pull it off. A terrible ache ran down her back.

"Eileen, hold her hands," William said, getting behind Mirabelle.

"You bastards, you – you perverts!" Mirabelle screamed, trying to keep her hands away from Eileen, but her niece was faster.

"Hey, Auntie, come on, give in. I mean, fuck, it's the best getting your brains fucked out every week," Eileen said.

Faster than Mirabelle could react, Eileen slipped the collar-clip on the chain and held Mirabelle's arms down easily.

"Please, you've got to let me, go – pleaaagghh!" Mirabelle screamed as William lashed into her ass.

She heaved up in the most horrible agony. William hadn't been lying, the pain was worn than anything she'd felt before. Another blow landed and she knew she'd have to surrender. There was no way she could take the agony. Sweat broke out all over her body as another blow landed.
