Monkeyboy is coming down from his orgasmic high and lines of worry begin to wrinkle his forehead again. "What am I doing... this is crazy! No sex is worth this." He hoists himself into a sitting position, although you're not sure whether he noticed that he just used his hand-like foot to adjust himself. "Please, sir. Can you change me back now? Maybe we can have some more fun tomorrow, but..." You sit up too and pull the young man close, stroking his well-groomed hair. "It's fine. You'll love this, Monkeyboy." You feel the delivery boy go tense in your arms. "Don't call me that. I'm Brock," he says quietly. You sigh. "Look, let's just sleep on it. We'll deal with it tomorrow, I'm feeling magicked out for the day." You don't want him to know that you really CAN'T change him again, even if you wanted to. Better he thinks you're some all-powerful warlock than him knowing about your magic ring and its limitations.
Monkeyboy is in a bit of a mood for the rest of the day. You try to soothe the situation with massages, playful touches, and a good attitude, but he's having none of it. It's really killing your excitement, you think, to have such an entertaining fantasy available and have it restricted from you. You can change Monkeyboy back into Brock (or something close enough) in a few days, but you want to have some fun. After all, you aren't usually this old, and your feet usually aren't these canoe-sized flippers either, but the delivery boy didn't complain when he was the one reaping the sexual enjoyment. He's probably still horny for you anyways, it's just he's so mad he's not allowing it. "Come on, Monkeyboy. Let's just fuck. You're wasting this opportunity. Next week, you'll be back to normal, driving your stupid delivery truck, and you'll be rock hard thinking about all the stuff we should have done together." The young man just stares at you blankly. There's no hate in his expression, but there is a LOT of annoyance. Past that, you have no idea what he's thinking. Honestly, it's boring to think about -- your interests are purely physical at the moment.
A plan starts to hatch in your head. It's not long before you can use the ring again, and you're going to see to it that Monkeyboy is a little more enthusiastic about the whole situation. You head out to the drug store, picking up a few supplies. You consider asking your temporary roommate and fuckbuddy if he wants anything, but can already tell that conversation won't go anywhere productive.
You decided to stay out for a few hours -- it's not like Monkeyboy was going to leave while you were gone, at least not unless he wanted to get thrown in some kind of testing facility. By the time you get back, its a little after 9PM, and the altered man is sprawled out on your bed, apish feet curled into a fist-like posture. He's asleep. You hide your purchases for the time being, and spoon Monkeyboy's fit body. He doesn't stir, and you relax, enjoying the feeling of his warm body. You fall asleep before long, and don't wake up for a while.

It's still dark outside when you wake up. Monkeyboy is still dozing, and you check the clock, seeing that it's around 4AM. Great, that means the ring is up and running again! You put your plan into motion, heading to the kitchen to start breakfast. Monkeyboy will be hungry when he wakes up, he didn't really eat anything yesterday. You had tried to offer him a banana, but he was not amused.
Your plan is pretty simple really, all you did was pick up some Viagra and testosterone supplements from the drug store. You figure if Monkeyboy is resisting his urges, you might as well ramp up his arousal a little. You grind up a tablet of Viagra and a few testosterone tablets and then make pancakes and bacon. You dump half of the powdered drugs into some batter, and stir the other half into a glass of orange juice. You're sure to separate the "special blends" for Monkeyboy, making sure your own breakfast isn't quite as volatile. Just as you're finishing up with the cooking, Monkeyboy drags himself into the kitchen, his huge gray feet slapping loudly against the vinyl tiling in the kitchen. You smile slyly and serve him his breakfast. "Thanks," the delivery man says, pressing his bare chest against your clothed one in a short hug.
You already know what you want to change, but you want the other man to finish eating first. You don't want anything to stop your enjoyment of his changed body, and your dick is already hard at indulging your foot fetish by rubbing your dick all over Monkeyboy's beastly feet. You decided that you'd like to make him less like Brock and more like Monkeyboy -- and the biggest thing getting in the way of his new role is his lack of fur. You have a picture of a chimpanzee from the local zoo pulled up on your phone, ready and waiting for a swap. As Monkeyboy takes his last bite of his dosed pancakes, you pull the ring from your shorts pocket, sliding it onto your finger. Turned away so he can't see, you kiss the ring, thinking of the chimpanzee's fur. You quickly pocket the ring again so that your companion doesn't see.
When you turn back around...
