Hours passed.
Charlie unlocked the door and walked inside.
"Greg!' he called into the apartment, "I checked out the Park. She was staying at a motel near there but she checked out this morning. I know where she-"
Charlie found Greg.
The half man, half horse was stretched out on the couch, very erect and breathing heavily.
"Hey, Charlie," Greg wheezed. He was speaking like an injured soldier, keeping calm despite a large amount of pain.
"Greg...?" Charlie exhaled.
"The change happens whenever I have sex, or do somethin' like that. It wears off after a few hours though"
"You changed back?"
"Yeah, but then I jerked off again. I couldn't help myself. The spell makes me extra horny when I'm human"
"What happenned?"
"Couldn't finish," Greg smiled weakly, showing Charlie his hooves, "It's been hell waiting for you. I need your help"
"Sure, what do you want me to do?"
Greg looked at Charlie, then at his throbbing erection, then back at Charlie again.
"Oh no! I am not doing that!"
"Dude!" Greg exclaimed, "I'm suffering here!"
"Maybe you'll just change back again"
"I know I won't. I know it. I can tell. It feels wrong"
"How can you possibly know?"
"Trust me. I do"
Charlie took a step backward.
"I'm not gay"
"You think I am?" Greg pleaded, "I'm not askin' you to enjoy it. I'm askin' you to help me out. You're meant to be my friend"
Charlie looked as though he was undergoing a powerful internal battle.
"Oh, you so owe me for this"
Charlie rolled up his sleeve and knelt next to Greg's crotch.
Charlie and Greg's cock shared a momentary glance.
"I can't..."
"Nobody else can help me, Charlie"
Charlie shut his eyes, let out a long squeak of disgust and reached out for Greg's cock. The moment his finger made contact, the intense pleasure returned. Greg let out a long moan of satisfaction.
And then the feeling left.
"I am NOT doing it if you make noises like THAT"
"I can't help it. It's the spell"
"This is just too weird"
"You think you've got it weird?"
Charlie could not meet Greg's cold stare.
"Just bite the bullet, man" Greg told him, "The quicker we get this done, the better"
Charlie nodded slowly to himself.
"Alright..."
He put his hand firmly on Greg's cock and began to move it up and down.
Greg's body trembled with euphoria. He could actually feel the change this time. His chest was pushing outward. His knees were turning backwards. His spine was stretching out. His feet were turning into hooves. Fur erupted across his body.
It met the crescendo and burst out of him.
He was now a chestnut stallion, laid on his back on a couch slightly too small for him.
He rolled over, got to his feet and made a gentle trot around the living room. He had never been happier, even if he was a horse. Being a horse wasn't so bad, especially as he knew it wouldn't last.
But then he considered what would happen next.
Charlie was in the kitchen, throughly washing his hands. Greg walked over to him.
"We need to solve this. When I change back, I'll just get horny and change into somethin' else"
"Well, make sure it's something with hands" Charlie shot.
"I'm being serious," Greg snorted, "We need to find this girl"
