Derrick looked around, then made his way to the center desk. The receptionist smiled as he approached. "Hello, Derrick! You certainly made some changes! Your family will be surprised!" He nodded glumly. "Yeah. Or have screaming fits." His family's reaction was worrying him way more than hat he looked like now. Weird. In just a few minutes he was almost used to being a monster sex beast.
The woman chuckled. "Might as well have fun, then. Most parents would have a fit over something as harmless as satyr horns. If you have to listen to the complaints, it might as well be worth it."
That made Derrick think. "Hebe said she had made me 13 years old. Is there someone here who could make me 17 again?"
The receptionist's eyes widened as she stared at his immense cock and balls. "That's a 13 year-old's?"
He nodded. "I figure it can't get much freakier than this, and I want to see if it makes a big difference."
"Ageing up is easier than getting younger. Just a second." She picked up a handset and said "Hey, Eros? I have got someone you HAVE to meet."
There was a flicker, and an incredibly handsome young man was suddenly standing next to Derrick. Maybe 18, he was well-endowed and athletic, with long dark hair and eyes that sparkled gold. Just looking at him got Derrick aroused, and that immediately drew the youth's attention. "So, what did you want.... HOLY SHIT!" The exclamation drew attention from everyone, but it was Derrick's massive shaft pushing out that kept them staring. Eros' mouth fell open and he looked up at Derrick. "That is the most amazing ting I have ever seen!"
The receptionist also stared as the huge organ pulsed up and the boy's massive testicles started to tighten. "Better than that, he is only 13 and wants to be 17." She grinned. "Hebe has been playing around some."
"Thank her for me!" Eros grabbed Derrick's hand. "We'd better get out of here before you make a really nasty mess."
Derrick started to say it was already too late, but as he shuddered and shot his massive load, he found himself in a different, and far more private setting. Eros nodded in approval. "That cum would make an elephant jealous. So, 13 going on 17? This id going to be great!"
Moving around Derrick, Eros inspected the boy as if he were a beast on sale, feeling his muscles, hefting the massive cock, and even pushing back the foreskin. The attention should have brought another erection, but Derrick felt nothing. Finally the young man seemed satisfied. He winked at Derrick and said "You are gonna love this!" The he grabbed Derrick's cock and squeezed it with both hands.
Derrick gasped - where he had felt nothing just moments before, Eros' touch sent a wave of pleasure, lust, and pressure that seemed to make his entire body explode. He cried out, falling backwards into a pile of thick cushions, overwhelmed by the intense sexual experience. His back arched and he felt himself erupt with multiple blasts of semen, his testicles aching as they were forcefully emptied. When the spasms finally ended, he lay among the scattered pillows, panting. That had been way more intense than before, and he felt so strange.
"Oh, yeah." Eros chuckled. "That is definitely an improvement."
Derrick struggled up and stared at his cock. There was hair around the base now, not thick but appropriate for a 17 year-old. However, the base was a good ten inches in diameter, and the cock itself had to be more than a yard long. The huge bulges of two soccer ball-sized testicles were evident. He forced himself to stand and found that he was towering over Eros. He as still slender, but now he had muscle tone and a little bulk on his seven and a half foot body. He'd be a basketball coach's wet dream, except that it was obvious he only had one purpose. Even soft, his cock dragged the floor, and there was a steady discharge of semen from the massive tip. His hips had altered even more, so he walked with a forced swagger.
Eros grinned as he admired Derrick. I've seen 13 year-olds who are not as big as your cock. And I think you'll find that any contact is quite... stimulating." He motioned for Derrick to lean over so he could speak into the boy's ear, but then pulled him into a passionate kiss. Derrick gasped and shuddered, the contact of lips just as pleasurable as stroking his cock. "Oh, you are going to have so much fun!" Eros chuckled. "Nearly nonstop orgasms! You are going to be the hit of the Pleasure Pit!"
