Her master stood, and took hold of his cock, so he could guide it against her freshly tightened asshole. He grunted as he slipped his erect shaft into it's favorite place, the ass that he thought was made just for him. He smashed his hips against her ass, before he put his arms around her and lifted her up out of the tub, and out of the room without even bothering to try her off. Trevor had a few things planned out, first... he very much wanted to get inside her cunt, he'd been putting off for to long. Then she could have those clamps off, and...well, he had something planned for her nipples, maybe the pain from the clamps would help get her ready for that.
"Are you ready to try Master's cock in your your pussy, Mandy?"
He asked as he walked them back into their room, before he sat down on the bed. He let her go so she could move around, after all he wasn't going to put his cock in her cunt himself...she could do that for him.
"Once we're done then we can free your nipples. Go ahead little Mandy."
