"Joe!" Dash yells, bursting into his room. The door hits the wall with a loud thud, causing her and Joe to flinch. Joe was laying in his bed before, but now is sitting straight up. Joe is a tall, thin black man with crazy dark brown hair and green eyes. He wears a red shirt with dark red strips along the length of the shirt and a pair of blue jeans.

"Other than almost breaking MY door, what is with all the yelling?" Joe asks as Dash closes the door slower than she opened it before zooming by in a spray of rainbow mist before landing on Joe's lap like a dog. Her front hoofs press against his chest as she looks up at him in excitement.

"I think I found another sexy way of using the spell twilight accidentally gave me!" Dash says with a hug smile. Her tail wagging like a happy dog.

"I'm all for experimenting," Joe says, patting Dash on the head before running his fingers threw her mane. She leans her head into his hand as she closes her eyes. "What is it?"

"Do you remember how the flip of the trigger word causes me to return back to normal?" Dash asks as she opens her eyes again. Joe nods in response, still betting her head. "Well, me and Twi discovered that I can go past that with some pain," Dash explains, looking everywhere but him as she mindlessly rubs her rump against his nethers. His dick was hardening in his pants from her soft rump humping his legs. "But with some added pleasure, there is no limit to how small I can get,"

"So you basically want to be my fuck toy?" Joe responds with a big smile.

"No!" Dash yells, lightly punching Joe in the chest. She pouts in anger as he laughs at her reaction. "I just like i-it when.." Dash trails off as she rubs the back of her head with her hoof. She stops humping him as she looks down at his stomick.

"When what?" Joe asks.

"I like it when you dominate me," Dash looks up with a cheeky smile and a deep red blush.

"Hu.." Joe says as he tries to process the information. "Why does that make sense,"

"You in?" Dash asks excitedly. Her wings spring out to her sides in anticipation as she bounces in place.

"I guess it's better than destroying my bathroom," Joe responds as the two get a good chuckle out of the memory. "You still owe me a new shower door,"

"Really?" Dash asks.

"Ya," Joe responds. "Custom doors for me are expensive,"

"Sex first, then we go to the bath and shower store to get a new door for you," Dash says, pushing her chest against his and placing her head just under his. Her eyes were half-lidded as she bits her lip. She starts humping his nethers again before he can respond.

He grunts before responding, "Deal." He then wraps his arms around her body in a hug before kissing her on the lips. His smooth lips contacting her soft ones. She sighs as they close their eyes before the two push deeper into each other. Dash pushes her body against his as she keeps humping his hips. Joe glides one hand up to the back of her head while the other slides down to her rump.

He massages her rump, his fingers slightly pushing into her muscular rump, as he scratches the back of her head gently. Dash lets out a moan of pleasure as she tries to push into his body. Her wings were now fully out in excitement. Dash separates from his kiss as Joe takes his hands and grabs the base of her wings. Dash lets out a moan as his fingers gently wrap around the base of her wings.

"Ready for some fun?" Dash asks seductively as she pushes her rump down into his hips while pushing her chest against his. Joe smiles before rubbing the base of her wings. She lets out a loud moan as her body shakes in pleasure. She catches her breath before speaking one very specific word. "Oneevery," Once the word escapes her lips, the magic takes hold of her. A bright purple aurora surrounds her body.

Joe instinctively starts rubbing her wings, causing her to let out another moan as she starts to shrink. She grits her teeth in slight pain as it sounds like a few bones break in the process. The magic fades as Dash relaxes against his chest. She now sits about 2 inches or 5 centimeters, shorter than she was a few seconds ago.

"Damn," Joe says. "Somehow that turned me on more," Joe smiles as Dash looks up at him.

"It'll be better if you take your pants off and slide that dick of yours in me," Dash says before standing up. Joe unbuttons his pants and slides them off before taking off his underwear. He kicks them off the bed before Dash pushes him down with one hoof. His head lands on the soft pillow as Dash lines up her slit with his throbbing dick.

Dash looks down at Joe with a smile on her face before dropping onto his dick in one swift motion. Joe lets out a moan as he grips the bed. Her tight slit surrounds and clamps down on his dick throbbing against her insides. "F-fuck," Joe says as he takes a deep breath in. "You're tight,"

"You think that's tight? wait for later," Dash says, moving her hips in a small circle. Joe sighs in pleasure as his hands relax. "Especially once you can use me like a sex toy," Dash says as she slowly pulls off of him.

"You know.." Joe says in between breaths. "Oneevery is a stupid trigger word," Right as Dash starts to drop back down on Joe, the magic returns at the sound of the word. Dash grits her teeth and shuts her eyes as she also lets out a moan as his dick slides into her. His dick seeming to get bigger, but she is really getting smaller.

Joe grasps at the bed sheets as her slit turns into a vise around his dick. His hips buck up into her, causing Dash to let out another moan as his dick goes deeper into her. Her body shakes in pleasure as the magic stops, leaving her 6 inches smaller, or 15 centimeters, than when she walked into the room.

Joe and Dash recover from the pleasure before Joe speaks up. "Look at you, you must be at least a half foot shorter," Joe says, patting the top of her head from his resting potion. Dash rolls her eyes and pushes his hand away before she rolls her hips in a circular motion. Joe lets out a grunt of pleasure before Dash retorts.

"If you were going to call me cute. Don't, I'm sexy," Dash pulls off of him again.

"You're cute and sexy?" Joe asks with a smile.

"That's a bit better," Dash respond. "Oneevery," Dash whispers before slamming down on Joe's dick. Joe lets out a loud and surprised moan as she shrinks again. The walls of her insides tighten even more around his dick. Dash's face now beat red as she lets out a loud moan of her own slip from her mouth. She now sits on Joe's lap a foot, or 0.3048 meters, shorter than she was when she first walked in. Joe sits up as he wraps his arms around her now small body. Her head now only coming up barely to his chest.

"Now you're cute," Joe says, hugging her against his body.

"I'll show you cute," Dash pouts back as her face turns red. She goes to move but is stopped by Joe's hands. Her eyes go wide as he lifts her up to face level with him. Plastered on his face is a wicked grin. She gulps as a small smile forms on her face.

"What were you saying?" Joes asks.

"Nothing," Dash responds quickly.

"This is going to be fun," Joe says as Dash starts to get a little worried about what he was going to do.

"What are you going to do?" Dash asks. Without a response, Joe pushes her back down on his dick as his hips buck up into her. He then quickly pulls her up before slamming her back down again. Over and over he does this. Dash's face turns red as her eyes roll up into her head and her tongue slips out. A goofy smile plastered on her face indefinitely. The two let out moans of pleasure with each thrust. Pressure starting to build inside the two.

Joe stops and slides Dash so the two are face to face again. "So, how did you like that?" Dash's legs twitch as she recovers from the sensory overload of pleasure. She blinks as her eyes return to normal before she brings in her tongue and closes her mouth.

"It was ok," Dash says, crossing her hoofs over her chest. Joe raises an eyebrow at the response.

"Looks like somepony needs to learn a lesson in lying," Joe says as fear stricks into Dash's heart. Before she can ask, he starts ruthlessly thrusting into her while bashing her down into his hips. Instantly Dash's face turns red and melts again. Joe's fingers dig into her skin as he lets out grunts of pleasure. His face turns bright red as his breath quickens.

"Ah! F-fuck!" Dash lets out a loud moan as she cums onto him. Her legs kicked as her body convulsed. He lifts her up to eye level again as her body recovers from the orgasm. Her breath slows down as her face returns back to normal. Her eyes are now half-lidded as she lays limply in his hands. "Just do what you want, but make it good at least," Dash finally admits. Joe smiles before pulling her off of his dick and lying her on the bed. This action confuses Dash until he moves to lean over her with the end of his dick poking at her slit. She shivers a bit as the head of his dick slides into her very tight pussy.

Rainbow Dash then lets out a high-pitched squeak as Joe thrusts the rest of himself into her as hard as he can. He pulls out and pushes back in as quickly as he can. He grunts with effort as he tries to thrust his dick deep into her. Dash's eyes roll back up into her head as she lets out her tongue. Happy moaning sounds slipped out of her mouth with every thrust. His dick pushes against the inside of her walls. His dick was almost too big for her small insides.

Joe speeds up as his orgasm starts to build up. He grunts as he thrusts hard into her, letting out his seed into her. His cum spills out onto the bed as Dash lets out a loud moan in response. Joe thrusts a few small times before pulling off of her and laying next to her. The magic returns to her body and slowly grows her back to her normal size. She tiredly drags herself, with a little help from Joe, on top of Joe's body. The magic fades as she rests her head on top of his chest.

"I think I liked it better when you were bigger," Joe says, looking down at Dash.

"I think so too," Dash says, nuzzling into Joe's chest as he mindlessly rubs her head.
