Ty watched the new boy as he skated away, and he made a decision: Kevin needed some further adjustements. If he had left him the way he was now, at the age sixteen, the age difference with Matt would have be excessive. So, Ty whished to be at Matt's house at the exact instant of Kevin's arrival, and so it happened. Kevin opened the door with his personal keys.
"Matty, honey, I'm home!" said Kevin loudly.
"Karyn what happened to your voi..." started to answer Matt coming from the kitchen. Then stopped, looking at Kevin with his mouth half open. "What? How..." It was then that Ty immobilized them both.
"Damn! I forgot to change Matt's memories! I will correct the error immediately: Matt - said Ty looking directly to the man - your girlfriend is Kevin, the guy in front of you, okay? He was the lady named Karyn you love, and he will explain to you how he has been changed into that some moments ago, and you'll accept it and you'll like him in that form much more than the previous one." Ty nodded, seeing a look of acceptance and appreciation in Matt's eyes.
"And now your turn" said Ky turning his eyes to Kevin, still frozen. Ty made some mental orders, and the boy's body changed again. His body stiffed a bit, his height increased and so his muscular mass and hairiness while he aged to 20. He sported a short trimmed beard, now.
"That's enough!" Said Ty, as he let the two lovers move again, after making himself invisible to both.
