Derrick woke lying in the grassy glade, and groaned as he sat up. His whole body ached as if he had done a hundred laps and followed that up with a hundred pushups. His hair was still matted with sweat, and he felt sticky and warm. The nymphs had really given him a workout. He started to chuckle, only to gasp as his eyes drifted down to his crotch.
The immense sexual organs protruding form his crotch could not be real - they were ridiculous, horse-sized or larger. Yet when he instinctively grabbed at them, he not only felt the heavy foreskin with his fingers, his cock reported a pleasant sliding sensation. "Shit! What have you done to me!?" He scrambled up, having to stand slightly bow-legged to accommodate the tennis-ball sized testicles hanging swollen and heavy between his thighs. He thought he heard faint laughter, but when he spun around, he seemed to be alone.
Part of the stickiness he felt was from a constant discharge of semen that was drying on his legs. Walking was both a challenge and erotic. Damn! His cock tip was down to his knees and not even fully erect! Being bigger had always been a popular daydream, but not like this! No human would ever be able to accept him - fuck, smaller horses might run from him. The nymphs had made hi a sexual freak!
He looked around for his clothes - nowhere to be found. Then Derrick frowned, for the thought of putting anything on was suddenly repulsive. As in he would probably prefer to eat shit than wear pants and a shirt. On the plus side, he also found that he didn't mind being naked. It seemed normal, even if he knew that a few hours ago he'd have been mortified. After walking a bit around the glade, even his monstrous cock and balls felt... natural? Not quite - he knew he was a freak like this, but the heavy weight and slapping flesh did not bother him at all. In fact, walking around was enough to stimulate him, causing the already huge cock to engorge. Did he have that much blood in his whole body? Erect, the shaft was almost as long as his arm, pushing out of the heavy foreskin like a dark battering ram. Too dark, and shaped oddly. Somewhere between human and horse, he thought.
What now? Would the nymphs change him back if he begged them? How long was this going to last? Did he want to see what he could do with it? There were centaurs and minotaurs that could accept him, but would they? Would that cause more changes to him?
