"I know," Charlie said, "This is becoming..."
Charlie stopped. He looked ill.
"What is it?" Greg asked.
"I feel..." Charlie squinted, "I feel so horny"
Greg started. He managed to make his equine face appear shocked.
"Oh no! You've got it too!"
"No!" Charlie pleaded, but his hands were moving without his direction. They unbuckled his belt and pulled off his pants and boxers. He thrust his erect cock toward Greg. Greg moved backwards and stumbled over his hooves.
"Come on!" Charlie said in a voice that wasn't his, "I did yours now you do mine!"
"Charlie! I'm so sorry," Greg cried, in a heap on the floor.
"Oh fine, I'll do it myself"
He clutched his cock with both hands and began to drive.
"Oh, shit, Greg!" he sobbed, himself again, "I can't stop it"
"I know! I know! I'm sorry!"
Charlie's shirt began to grow big. No, Charlie was shrinking. As he drowned in his shirt his hands continued jerking. His ears were the first to grow. The grew upwards and outwards, becoming huge spoon-like dishes. Whiskers began to force their way out of his nose. Fur began to flourish on his skin. And then he disapeared into his shirt.
"Charlie"
The shirt lay on the ground, amidst Charlie's pants and boxers, still jerking rapidly. After a while, the movement slowed and stopped.
A hare scrambled it's way from beneath the shirt, looking very panicked.
It then shot Greg a very malicious look.
"This is all your fault!"
