Rub, of course

As Mark looked upon the voluptuous redhead he couldn't find it in himself to refuse her. He was only helping her after all. He nodded and Vix smiled widely leading him to the contraption and guiding him onto it. It was a weird thing, unlike anything he had seen before and he was moved into a sort of crouching position, his rear sitting on a narrow bench and his legs bent under him, resting on a cross pole.

Vix placed his arms on bars that extended above him, the end result leaving Mark sitting up and leaning forward, his back stretched out. It made sense, he thought to himself despite never seeing such a weird massage set up before.

As soon as his hands gripped the bars above him the other two girls appeared out of nowhere, hurriedly lashing his wrists to the contraption with duct tape. He cried out but Vix immediately slapped him hard across the face. His ankles were similarly lashed and just like that, Mark found himself at the mercy of the three young women.

As Tish and Andi began cutting away his clothes, Vix pulled open the curtains before him revealing a wide assortment of sex toys. Dildos and vibrators, whips and chains and things he didn't even recognise. He was about to scream when Vix whipped a ball gag from the wall.

"Better keep quiet little man, unless you want to wear this. Oh, and we already have plenty of pics of you drinking with us that we can show your lovely little wife, if you don't play along."

Mark fell silent. He knew he was fucked and at their mercy. Just how fucked, well... he was about to find out.
