... testing the straps "for safety" before moving over to stand next to Carmen. The shorter Engineering major held her smartphone at the ready as she addressed the group.

"OK, boys. You know the drill. You also know what's at stake this time around. Not only could you earn the extra $100 if you win, you will suffer a bit of extra stroking if you don't. Here's your chance to put everything you've learned today to good use. Good luck!"

With that, Carmen tapped a button on her smartphone and all five of the ECT machines began their work. The pre-programmed routine began again, progressing inexorably through the slow, medium and fast strokes before adding the rotation and beginning the quick top and bottom strokes. The intense stimulation of the four quick strokes at the top of our shaft, followed by four quick strokes at the bottom and wrapped up by two full-length strokes was too much for Tommy and Cody.

To my dismay, they held me so tightly I barely was able to twist my body, let alone break free. All the while, the jelly sleeve was relentlessly polishing my apple, using my churned cum as lubricant.

Seeing my plight was too much for Brendan as he shot his load and began his own round of post orgasmic torment. His grunts during ejaculation quickly escalated to a couple loud shrieks as the ECT device made his cock feel like it was on fire. With what was clearly a great effort, Brendan got control of himself, reducing his cries to persistent whimpers at his continued pleasure and pain.
