Summary:

Hikaru is the size of a fairy, and Magnus couldn't be more intrigued.

Reluctant consent because there's a big power dynamic at play.

Chapter Text

When Magnus felt like being nice, he would just put him on his desk and leave him alone. He liked to watch Hikaru struggled in his tiny dress, trying to make sure that he wouldn’t expose himself whenever he moved. That was all futile, Magnus never bothered to tell him that whenever he reached down to cover his front, the back would just flare up to reveal his hole like he was asking to get fucked. It was much better to sit back and watch the literal tiny figure move about as if he still had any power left. 

At the moment, he had Hikaru laying on a little vibrating ball that was much bigger than him. At the size of a small computer mouse, it was hard to find anything that was smaller than Hikaru anyway. 

Magnus had stripped him naked and poured baby oil on him, leaving the tiny figure a slippery mess, before planting him on the toy and told him to clung on to it for as long as he could. 

“Ah!”

He looked at the mess on his desk with a frown. Hikaru had somehow slipped all the way down and was trying to find a way to climb back up without hurting himself. He had cupped his penis with one hand, and was trying to find a way to climb up the equally slippery ball with the other. 

The air conditioner was a tad too cold, and Magnus should have adjusted the temperature a long time ago, but watching the quivering figure tried to cover and warm himself at the same time was too fun to miss. 

Hikaru was already starting to sob. The hand that was supposed to support his body up was shaking, too busy wiping away from the trailing tears that were spilling from those pretty eyes. 

Magnus promptly turned the vibrating toy off, “Get on with it.”

What followed was a small whimper and a tiny sob, then the small man made his way to the toy again, wiping off hands on his body as if he could chase the slippiness away. Once he got his hands properly on the curved surface, Magnus reached out to support his tush with his pen, pushing him up lightly. 

Hikaru almost breathed a sigh of relief at the help, but then the sigh turned into a loud moan when Magnus twisted the pen so that the tip of the pen was poking at his rim instead. It took one slip for the tip to enter him, his hole still open from all the opening that Magnus told him to do before this. 

Magnus pushed the pen up, digging further into Hikaru’s ass as his lithe body got tugged up the toy along with the movement. Once he got Hikaru where he needed him to, Magnus took the pen away, leaving the tiny man a sobbing mess on the toy, body still glistering from the baby oil from before. 

“D’you wanna cum?” He asked, knowing that Hikaru was probably too far gone to say anything. Said man answered him with a nod, his long-forgotten dick still hard and attentive despite his apparent tears. Magnus quirked his lips, “Hump the toy then.”

“Huh?” Hikaru dizzily asked. He looked ready to be devoured, mouth agape, like he was waiting for Magnus to shrink down to his size and face-fuck him. He should do that soon, buy some sort of long mini toy and make Hikaru suck on it as he waited for Magnus to shower him with his cum.

“Hump the ball like the needy slut you are, Hikaru.”

Hikaru gave him a scowl, but he obliged, nevertheless. He had learnt from his many lessons. Magnus used to have to force discipline onto him, needed to make him learn how to properly thank Magnus for housing and dressing him, even when he had turned into such a pathetic state. 

Now, Hikaru knew what to do. He softly grind his hips down against the ball’s surface, resting his face at the nook of his elbow as he tried to hide from Magnus. It was as if he believed that Magnus wouldn’t be able to see him if Hikaru couldn’t see Magnus. 

It took a few limp and sloppy thrust for him to cum, especially with Magnus slowly patting his ass with the pen earlier. Hikaru continued to lay flat, clinging onto the ball, right on top of his own mess. 

“...Magnus…”

“Good boy,” he lifted him up from the toy and lowered him down to a cleaned jar. Hikaru immediately curled to one-side, his slippery, cum-stained body pressing against the clear glass as he rearranged himself. The sight never gets old, “Say ‘ah’, Hikaru.”

Magnus didn’t need a lot to cum. The familiar sight of Hikaru with his chin tilted up, mouth opened, and tongue poking out was sinful enough. It was useless, of course. He could never really swallow his load, always ending up with more of a shower where Hikaru was usually left drenched in his semen, and having to beg his way out of the jar to clean himself up after. 

“Please, Magnus.” He'd even learnt to beg so nicely. 

Magnus was so proud that he let him out of the jar after nearly an hour instead of the usual two.
