"Darren, what are you doing here?" you ask when you see a fellow worker at the office you just started at.
He responds with, "Whoa, that gear was potent! I mean, look at you. You're a beast!"
"What the hell is going on?! You sent me this junk?" you ask as you lift your shirt to reveal the harness.
"Junk? I paid a 'specialist' in such matters to craft that enchanted device."
"Enchanted, you mean this is magic?"
"Did your brain leave when you got that brawn? Yes, the leather is magic. I guess an explanation is due."
Your mind is racing. Darren is talking about magic, you are trapped in the body of a bear, and it appears he was the cause of this. Lacking any better idea, you decide to hear him out.
"You see, I'm gay. But only really masculine men turn me on. I wanted a lover who was the epitome of 'bear'. Unable to find one, I sought out a, let's call him a wizard. He said that I could choose one person to craft trans formative gear for. I chose you. Your personality was great but your body wasn't butch enough, and you were straight."

"I don't want any part of this," you begin. "Change me back right now. I don't want to make love to a man."
An evil grin appears on Darren's face, "At what time did you think you any choice in the matter? Ever since you opened that box you have been under some degree of control. You were compelled to wear the leather, and to wear it here. So long as you wear it you are under my direct control. Now get on your knees as a sign of obedience!"
Unable to resist, you drop to your knees.
"Now it's time to live out MY fantasy. First of all, you need to look the part of the leather bear. Let's go to the..."
