They bind you

The two men grab your arms and push you face down over something that looks very much like a piano bench, quickly strapping your arms and legs to it. There is a hard cushion under your belly, pushing your ass up higher. You cry out, once, but then are stifled because your professor stuffs your torn panties in your mouth as a gag.

You feel oil being rubbed into your ass, and you writhe, although you're not certain whether your writhing is from pleasure or from fear. You moan against the gag as a finger impales your ass, probing you. You've only once had a finger there before and now you're certain these men mean to fuck your virgin ass. You start to cry, your sobbing muffled by the gag, tears starting from your eyes.

Simmons waves something in front of your face. It looks like a glowing pink wand with smooth ridges down it's length. It's flexible, moving a little as he waves it. You've never seen anything like it.

"You've got the perfect spot for this, slut," he says hoarsely, and takes it out of your sight. A moment late you feel pressure on your tight rosebud ass again, but even less than the finger that was there before. Whatever it is slides in easily, and then deeper. As it enter you it feels like little balls being pushed into you and you realize that he's inserting the wand. You think of how long it was and squirm helplessly.

You're aware that once again your body is betraying you. Despite the humiliation and degradation you feel at what is being done to you, your body is quivering with arousal, your pussy hot and wet, your nipples still pinched by the clamps they put on earlier. You're grunting into your gag like an animal as the wand keeps steadily impaling your ass, going deep inside you. Suddenly it stops, not going in any further and you relax a bit, involuntarily enjoying the feeling of your ass being filled.

"She took it all," Simmons laughs, patting your ass fondly. "You're a champion, Lisa."

"Turn it on," Richards says. "Let's see how she likes that."

You don't have time to wonder what he means before pulse of vibration goes through you, the wand buzzing with frenzy inside your ass. You arch your back and neck and groan deeply, loving the sensations exploding in you despite yourself. In a moment you start to come, your body shuddering with spasms as orgasms rip through you.
