Brock's eyes are staring at his changed crotch. Although he had already been reduced in size only a day ago, he had undergone a much more dramatic change. His dick (well, yours originally), had been a respectable 6 and a half inches only moments ago. Nothing compared to the 11 inch, vein-covered monster that was painfully hard in your boxers, but respectable. Now, Brock was looking at a penis that couldn't have been much more than an inch. You had done some light reading about gorillas this afternoon, to see what Brock might be in store for, and had read that most apes and monkeys have very small genitals. You hadn't known this before today, and clearly, neither had Brock. His eyes were wide, and tears were already wetly streaming down his face onto his bare chest. "What is this... is it... am I... no. No, no... this isn't real. It's..." Betraying his confusion and woe, the leathery black nub that was now his dick was leaking precum and pointing towards the ceiling. The delivery boy looks at you, waiting for you to say something to explain his unreality.
You smile coyly. "That's interesting. I like these more, though. They look good on you." You gesture to his meaty gray feet. Brock's eyes travel down and his mouth is hanging open now in shock. Where the young man's ankles meet his shins, his brown leg hair transitions into a thick coating of coarse black fur. It completely covers the top of his feet, which are now huge. Probably as big as... no... maybe BIGGER than your head. The bottoms of these feet look tough and calloused. Brock jolts forward and grabs one, pulling at the tough hide and the fur, and gasping with the pain. He flexes his left foot, incredulous when it responds by making a loose fist shape. "They're real and they're yours," you say, "feet to match the meat." Brock's sadness is gone in a flash of anger. "You turned me into a freak! A complete freak!!! Why did you do this? How am I supposed to go out like this?" Your smile widens, and your massive dick is begging for some attention. "You're not. At least not for a while. You're going to stay here for a few days. You'll be my Monkeyboy."
Brock is aghast. You continue. "Don't worry, it'll be fun. At the end I can even change you back," you say, although here you know you're telling a bit of a fib. You can't guarantee you can get him back to normal, half of the ring's changes will be random, after all. "Or if you'd prefer, I can make some improvements... to your specifications of course." You wink. Brock seems to think about this. His eyes are a little glazed over, and his hands are back to his feet, each roughly clasping the other. "Besides, I still find you sexy. And I think you find me sexy too." Brock blushes a little, looking shameful. His dick has still been hard this whole time. You hadn't thought he would be so submissive, but it definitely turns you on. Your boxers are practically dripping with precum. You rip them off your body. "So what do you say Monkeyboy?" Brock eyes your glistening cock, and licks his bottom lip a little. His beautifully tan skin is moist with sweat. He gives a small nod.
He reaches out with his feet and grabs you by the waist. Even you're surprised by the strength behind the grip. He uses this leverage to hoist himself closer, and you take the opportunity to rub his apish package. It's so small, practically all you can do is stroke it with your thumb. Brock, now your willing Monkeyboy, releases his grip from your waist with one of his grasping feet. He wraps the powerful digits around your thick cock and begins to pump. Neither of you last very long, the strange situation inexplicably heightening your arousal. But that's alright. Br... no... Monkeyboy will be here for a few days. And you're already thinking of his next change.
