Must. Cum. NOW.

10:10.

Like clockwork, the familiar sensation of desire budded between my legs. It was like an itch you yearn to scratch ... only I couldn't move my fucking arms.

"Okay, guys, this isn't funny," I said. Each of them was looking at me with a different expression. Amanda looked curious, Candy uncertain, and Karishma was positively pleased.

"No, it is funny," Karishma said. "And anyway, you have to learn how to control yourself."

But I couldn't control myself. It wasn't medically possible! My need for an orgasm was building more intensely, and I felt a dull roar inside my vagina. It was like my insides were shouting at me, demanding satisfaction.

"Fuuuuuck!" I shouted and started bucking my hips in my chair. I'd never felt such an intense need to touch myself nor such overwhelming powerlessness and distress.

10:11.

I started to pull my hands against the cuffs, digging the metal into my wrists. Obviously, that didn't help. I wriggled my ass on the chair, trying in vain to scooch the corner of the seat between my legs. I tried to stand up, but a feeling of dizziness overcame me, and I plopped down in despair.

10:12.

This was torture. By now, I was crying and pleading. "Please!" I shouted. "Please, please, please, pleeeeeease!"

If my vision hadn't been clouded with the fog of desire, I would have seen Amanda staring at me in utter shock. I would have seen Karishma gloating, drinking in every excruciating spasm. And I would have seen Candy biting her lip and doing everything she could to look away.

10:13

But she couldn't look away.
