The erotic sensations distracted Derrick form paying much attention to how they got there, but he found himself following the satyr out into a rolling meadow. There were tress surrounding the grassy area, and dozens goats and sheep were grazing. Several looked up at the intruders, but none seemed alarmed. The satyr released his hold on the boy's now-rigid cock and slid a hand under the massive dark testicles below to heft them. "I bet you are feeling some pressure now." He grinned up at Derrick.
"Fuck, yes!" At first Derrick was going to ask why he had enlarged the testicles so much, but then he saw some of the male sheep and goats and realized the heavy sack was normal for the animals, at least. Even so, he groaned and shuddered as a spurt of semen escaped. The swollen balls should have been uncomfortable, but Derrick was even more turned on. His cock was dribbling liquid, the flat equine flare slick with cum. "I think I'm going to shoot six feet when I finally let loose!"
"Then we should get you take care of." The satyr gestured around. "Quite a bit of choice here for you. I'll be glad to take care of your hard-on, or you can make a ewe or nanny goat very happy."
Derrick was ready to mount anything. He'd never been so hot and horney in his life - having sex had become a need.
"One word of caution." The satyr chuckled. "Once you start, it will be hard to stop. Fuck a ewe and you'll want another, and another. Somewhere along the way you'll find you are on all fours as a total animal, but you won't care. You'll be a ram or a billy goat and spend the rest of your vacation having sex. Or you can go a few rounds with me and end up a satyr."
