She tosses me onto her bed. I wriggle into my usual position.

"Not this time," she says. Seems I'm to be on my side, with knees drawn up. The blindfold isn't normal either. The gel is cold, the instruments colder. 

I feel the mattress sink. Someone else is here. The first tingle of electricity... "Good girl," she says.

Now it begins. A gloved hand pushes my knees closer to my chest, and I know it will be good. My climax comes almost immediately. 

Something is put inside my mouth. I hear more voices.

It goes on for hours.
