The swap should be interesting, considering you brought home a medium-sized dog -- a Boxer, to be exact. Last night you made a call to the pet shelter for an early appointment while Monkeyboy was in the bathroom. It was easy, all the shelters in the city are too full. They're desperate to offload any pets they can, no questions asked. They even gave you a bag of supplies -- mostly useless stuff like dog food, nail clippers, stuff like that, but a few things might be fun to use with Monkeyboy. You can hear the unnamed dog whining in its carrier, begging to be released. You open the bathroom door to let it out and finally check on your beastly fuck buddy.
You see a strange change affecting Monkeyboy, who is lying on the bed in a twisted posture. His lightly hairy legs seem a little thinner and shorter to you, maybe losing a quarter of their original length. His head seems to bend back farther than usual, too, and the former delivery boy is wriggling to find a comfortable position. Of course, you swapped the Boxer's place in society with Monkeyboy's, making him your pet. (And making the dog have the social status of a human, too.) But what is this other change exactly? It's something more subtle than the simple swaps you've been used to so far. You open the animal carrier beside your bed, and the Boxer crawls out awkwardly before standing upright on its two hind legs, paws resting limply at it's sides. Stretched to its full height, it reaches past your belly, and gazes up at you with drooping black eyes. "Buh," it barks quietly, clearly confused by its new form. You think you understand what's happened -- the dog and Monkeyboy switched their postures, and their bodies adjusted accordingly. If you're right, Monkeyboy has to walk on all fours now.
Monkeyboy turns his head and stares at you angrily, wriggling on the bed. "What did you do to my body? I thought you JUST said that leaving me all messed up didn't make sense?!" The Boxer pads around the room tentatively, taking small steps. His nails click on the hardwood floor of your bedroom, the sound layered over small whining barks. You'll have to let the dog free later, he's going to have to fend for himself as a dog in human society. After all, there's only one beast you want to keep around. "No, Monkeyboy, I just meant we had to change some things around to make the situation a little more fun!" Monkeyboy cringes. "Don't call me that! Please, can't I just change back?" You sit next to him on the bed, and help him shift his body so he's standing on all fours, propped up by his arms and shortened legs. He turns and plants his butt on the bed in a doglike posture, hands in front of his groin and legs sticking out on either side. "Look, I'm magic right? Just think of this as a vacation. You were having so much fun exploring your sexuality with me the past couple days, and I'm just helping you experience new depths. I bet you're turned on, aren't you?" You slide your hand down to the small of his back, tailless for now. That might have to be next on your list, you think, running your hand across his legs and stroking his apish feet. It's like you're holding hands, almost, the fingerlike toes grabbing your palm firmly. Your new pet just shakes his head in confusion. "I mean, yeah, but..." You interrupt before he can talk himself out of it. "Well, great! Then just trust me. You can be back to normal in a while, just enjoy a little bit of roleplaying with me before then," you say, sounding confident. You're not really sure if you can reverse all of these changes, but Monkeyboy will never go along with this if he knows that. It shouldn't be too hard to make him a full-blown human again, but whether or not he can ever be the old Brock again is another matter...
Monkeyboy cuddles into you a little with a smile. "Alright. I guess I am having fun, sort of. If you can change me back, I'll try to play along a little more." You grin, feeling a few extra wrinkles in your smile. Being a little older is fun, but sometimes it's hard to forget these weird little differences in your body. "Great, Monkeyboy. For starters, let's..."
