As the two boys are sleeping the beer they drank starts to take effect. It happens first to Jesse. Jesse starts to dream about running through a green meadow with the grass between his toes. He run about laughing and giggling with pleasure. The he dreams he feels the wind whipping past his tail.
As he is sleeping, he rolls onto his belly then stands up on his hands and knees sticking his sleeping rear up into the air. A first its nothing but slowly a fleshy lump appears on his rear. Slowly, inch by inch the lump grows away from his rear tenting his briefs and his sheets as he sleeps. When the things has grown to almost a foot long his briefs tear in the middle and the tail rises as high as it can lifting the sheets well up behind his rear. By morning Jesse has grown a 2 foot long tasseled donkey's tail.
About halfway through the night, Josh starts to dream. Josh's dream was about him lying on a large field of green grass. He slowly gets up and walks over to some buttercups and smells the one at a time. In his bed, Josh spreads his legs apart and slowly a tail grows between his butt cheeks and out between his legs slowly stretching his boxers. They are slowly pull off his body by the growing tail and near morning he too ends up sleeping on his hands and knees. His boxers fall down to his knees.
Morning light slowly wakes them both.
