Math

"...Math," I chirped, watching the hot water cascade down the curves of the three girls standing in such close proximity to each other, and to me. "...Tr-tr-trig. Trigonometry."

"With Ms. Mailer?" Amanda asked, still stroking me from between my best friend's legs. She said it as if she already knew the answer, or had known it, my succinct answer suddenly jogging her memory. "That's fine, you'll be a little late. Nurse Olivia will let her kn--" she lost her breath mid-word as the kneeling blonde freshman behind her slid a finger into her asshole. "Ooh... good work, kiddo, you found it." Amanda bent forward somewhat to give the girl more access, reaching around Kathy with the hand not occupied with me to grasp one of my friend's medium sized breasts. She started working my shaft in bigger movements, which had the added effect of dragging the side of her wrist back and forth along Kay's slit. Kathy closed her eyes and breathed heavily.

This was admittedly one of the hottest things I've ever witnessed, and I watched the three girls carry on this way for a minute before something inside compelled me to interrupt. "Should I go now?" I asked. I'd just ejaculated not ten minutes prior, and I knew if this continued I'd go another.

"Patience, young Doe. Aren't you having a good time here?" It was a rhetorical question. "Can you finish washing his back, Kathy? John _does _need to hit the road here soon."

Kathy composed herself quickly, nodded, and stepped around me. Amanda had withdrawn her own hands and was lightly kneading her nipples between thumbs and forefingers. She stepped forward and the head of her strap-on touched my own cock, head to head.

"My ass is clean enough, Blondie. Do me a favor and soap up my dildo, would you?" Tori walked on her knees around the nurse's assistant and wound up between us.

I watched in awe for a moment, before Amanda reminded me what I was supposed to be doing. "Did three naked school girls make you forget how to jerk it?" she asked. I tentatively started masturbating again.

Tori was in the midst of lathering up Amanda's strap-on when suddenly the nurse's assistant grabbed her by her hair and forcibly dragged her cheek across the thing's plastic surface. She might have been crying, slightly. Perhaps it was just soap getting in her eyes.

Kathy, from over my shoulder, meekly objected to the treatment of the underclassman, "Amanda, go easy on her."

"She loves it," Amanda replied. And sure enough when she took her hands away, the girl kept rubbing her face against the plastic phallus. Taking a handful of her wet blonde hair, she put it in my own hand, then pressed the whole resulting damp wad onto my dick. "Have you ever masturbated into a girls hair before? I can't say I've seen it done, but I was feeling inspired." She was right, it felt amazing.

Kathy finished washing me then turned with apparent disapproval to Amanda, who was thrusting at Tori's young freckled face. "The bell is about to ring, shouldn't John be on his way?"
