Derrick eyed the nymphs - they all looked like beautiful girls, slender and small, and green. From what he remembered from Internet sites, they were connected to trees somehow, and they also were supposed to be very... um... easy. All it took was the thought to get his teenage hormones ranging and he started to pound erect. Anywhere else he would have turned beet red and slunk off to try relieving the pressure himself. But here? Derrick walked over to a cluster of three nymphs, shifting awkwardly a couple of times to get his erection out of a bind in his shorts.
They all turned to watch as he approached, giggling to themselves. Then they moved, almost as one, to surround him. Hands were suddenly all over his body, lips and tongues pressed against him, firm, warm bodies rubbing against his. At first Derrick was afraid they would take him right there in the lobby. But he was tugged and pushed gently off to a side exit that opened up into a beautiful forest glade. Trees and flowers surrounded a clear pond, though Derrick had trouble paying attention to anything but the nymphs.
Somewhere between the lobby and here his shorts and shoes had been removed, freeing the almost painful erection. Derrick gasped as one of the nymphs leaped up suddenly and impaled herself on his aching shaft, bottom out and then rocking with her legs wrapped around his thighs. He had never done more than masturbate before, and the shock of her slick, tight flesh around him blew away all thoughts. Instincts took over, and he thrust blindly, falling onto the soft grass and rolling with the nymph in wild abandon. He did not last long, jetting into her with a cry, straining in final release, and finally falling back in a confused daze.
A second nymph leaped on Derrick, and he shook his head. "No way! I'm...." Then his eyes widened as she slid back over his still partially-erect cock and began to masturbate him with her slick cunt. If anything, he seemed to get harder than before, and when he was fully aroused, she settled down on him and rode him like a bucking bronco. Derrick cried out, his back arching and arms flailing - it was too much! Was it pleasure or agony? Oddly he lasted longer this time, and shuddered in powerful release. The nymph continued to ride him until he slid out of her, then sat on his crotch grinning down at his sweat streaked face.
"Oh... wow." Derrick wheezed out the words, too exhausted to even sit up. He hadn't dreamed, hadn't imagined anything like this. But then the nymph on him stood up and the third settled in her place. "No!" he moaned weakly. "I can't. There's nothing left."
She slid off, and at first Derrick thought he had a reprieve. Then he felt her tongue on the base of his shaft, caressing his testicles, lips pulling at oddly loose skin. Still breathing hard, he lifted his head enough to look down. The sexual equipment getting attention from the last nymph wasn't what he'd started with. Even if you discounted more than double the length and width, a heavy foreskin now covered what had been a circumcised penis. A penis that, impossibly, was coming erect again. And he felt pressure building in testicles that had to also be at least double what he'd had to start with.
The third nymph grinned feraly at him and crawled back up over his chest like a prowling cat. Derrick panted in fear and excitement. He was half afraid he would have a heart attack at 15, or have his suddenly oversized cock explode. The nymph's tongue pressed into his mouth, tasting oddly of grass, and gave him some lessons on passionate kissing. Then, still lip-locked, she slid back and engaged his fully roused shaft.
Unlike the first two, this green girl took her time. She slid slowly down, bottomed out, and then pulled herself back up with equal deliberation. Derrick couldn't breathe, couldn't speak, his head slammed back into the grass. His body was on automatic, thrusting up, muscles locked, his mind overwhelmed by pleasure/pain that did not stop. Part of him wanted the sex to continue forever, part of him wanted it to stop. She dragged it out impossibly long - Derrick shuddered and sweated, the world closing in to be nothing more than joining of their bodies. When he finally was allowed release, it seemed like he had a firehose between his legs. He convulsed, the nymph crying out in pleasure as he screamed and thrust... and passed out.
