After being chased out by the young women, and then by the neighbor's dog, Stan and Billy in goat form head into open pasture. A strong male bond had formed between the pair and all that afternoon, in the shade of the trees the pair mated. First Billy fucking Stan and then Stan fucking billy.
The pair rested by a small swimming hole after grazing in the evening and slept near the swimming hole's edge.
Toward nightfall, the clouds had gathered and there was a dreadful downpour. Billy and Stan woke and were startled. Being completely disoriented, Stan followed the more dominant Billy and that led them into the pond.
The pair thrashed around in the mud on the bank and lost their footing several times, collapsing and rolling in the mud as they tried to get out of the pond.
Finally, Billy bleated and began swimming toward the far side of the little swimming hole, Stan followed. The pair climbed out but something was different. As with the women, the men were changing back into human form. Slowly Stan and Billy shed their goat hair and form and were left as the men they had been except, better. The rain ended as they finished changing back and the moon came out.
The women got beauty and slim yet buxom figures for their experiment with the Satyr cream. Stan and Billy got muscular hairy bodies and much more than average sexual equipment. Billy scratched his full salt and pepper beard.
"Damn!" the older man said, "I think we got a good deal out of the bargain!" he said looking at the bearded youth in the moonlight, "You look good enough to eat!" The middle aged trucker grinned.
"Yeah, well all I've had all day long is grass so I'm pretty hungry too." Said Stan lustfully, "Why don't we feed each other some fresh protein?"
For the next half hour the pair sucked each other and then, the goatish lust still with the pair, Billy fucked Stan again.
It was two or three in the morning when Billy and Stan made it though back ways to Billy's truck. He had a spare key hidden away on his truck and they both entered.
Over-sized flannels and jeans were all Billy had, but it was better than being naked even if the were a bit tight.
The smell of the cab's sleeper was still rank with goat piss, but this only aroused the pair more. The drove to a motel and checked into a room to continue their mating and of course, to rest from a very long day of being goats.
The next morning, the two naked men awoke. As they lay together, cuddling and kissing, they thought up ways to pay Sarah and Amy back for kicking them out so callously.
