Katsuki wasn’t even on one of those websites when he saw it. The ad itself wasn’t especially lurid but even a quick perusal was enough to have his face flaming and him glancing around his empty apartment guiltily.
It wasn’t so much the sexual nature of the product that he felt embarrassed about but the fact that Deku immediately came to mind when he read the description.
No, he shouldn’t. Their friendship was too precious. All the more so because of how he had treated him before. It wouldn’t be right.
But on the other hand, who was to know.
~~~~~
Four weeks later, the product arrived in discreet packaging and was left on his doorstep. Collecting it as he arrived home, Katsuki rushed it inside despite no one being able to tell what he had ordered.
After eating dinner and cleaning up, Katsuki finally opened his purchase.
The compressed doll sprang out as the pressure of the lid was lifted, startling Katsuki. He roughly pulled it free and it took shape before him. In full honesty, Katsuki had been prepared to be disappointed despite the product’s price tag but what was before him took his breath away.
All the company had required was a brief physical description and a good photograph of the subject’s face, so what sat in front of Katsuki was an eerie replica of Deku. Naked.
Naked, and ready for his use.
Heart hammering, Katsuki took his new doll to his bedroom.
~~~~~
Izuku had opted for a night in. He usually had such a busy schedule this rare night of doing nothing was a treat.
Curled up on the couch, Izuku stared at his television with the bare minimum of attention on the cusp of digging out the remote to change the channel when he experienced a sensation that he would have to call exploratory .
Looking around wildly confirming that he was indeed alone, Izuku was at a loss.
He held still, waiting to see if it would happen again. Perhaps he’d dozed off and dreamed it.
But there it was again! The feeling of hands sweeping down his body and, he choked, plucking gently at his nipples.
Izuku began to sweat as the brushfire of arousal started up in the wake of the phantom hands playing with his body.
Sliding down to lie more fully on the couch, Izuku found he could not bite back the whine crawling up his throat as his nipples continued to be played with. He’d never really thought of them as sensitive but he was already half hard from the gentle brushes and pinches.
Pulling up his oversized t-shirt to his armpits, he stared down at his nipples gone pink and hard from the ghostly hands working at them. Then suddenly, the sensation was gone. Izuku laid there panting and feeling vaguely disappointed. He reached up to tease at a sensitized nipple, and gasped at the hot feeling that poured through his veins.
Why did it have to stop, was the question that was uppermost in his mind though lower down there were other questions like, what was happening and who was doing this, but those didn’t seem important in the face of his frustrated arousal.
Then he felt something damp brush around his hole.
Oh.
A finger pressed in. Izuku had experimented during his “me time” on occasion but the slick, shallow in-out of this ghostly finger felt so much more interesting. He squirmed and bit back a whine as he widened his knees making room for, well, no one but he felt better as the finger worked into him further and further with each thrust.
He was fully hard now and just starting to think he might want to push his comfy sweat shorts down when the finger curled hitting the bundle of nerves deep inside him.
“Gahnnnnah,” Izuku cried, shoving at his shorts and boxers, freeing his rock-hard cock that had begun to leak.
The finger pulled out, and didn’t press back in.
Izuku could have cried.
It had felt so wonderful, now his hole clenched and fluttered around air feeling damp and hollow.
Grumbling, Izuku sat up a bit to push his underwear and shorts down but they had only made it to his knees when a far wider, blunt something nudged at his hole. Before he could draw breath, it pushed in.
Izuku screamed, flopping back onto the couch as the phantom dick, it had to be a dick, pushed inexorably into his ass as he writhed and clutched at the cushions. Gasping and heaving, he kicked the shorts down until they hung onto one ankle freeing his legs to be pulled up and out trying to at once relieve the pressure and revel in the fullness in his ass.
It seemed to go on forever, the ghostly dick molding Izuku’s insides to its length and girth until finally it stopped and Izuku could not help feeling stuffed and perfect. Rather than softening, he saw that his dick had remained hard and had leaked a puddle onto his stomach.
Until this moment, Izuku had made a valiant effort in not thinking of anyone in particular to go with the phantom touches but now with the ecstatic fullness he could not help but wish that it was Kacchan’s cock splitting him open, a smug grin on his face.
A single tear slipped out as Izuku squeezed his eyes shut imagining Kacchan over him, in him, when the dick inside him pulled almost all the way out before plunging back in with force.
Izuku moaned as the ghost dick fucked him, hard.
It seemed to change angles despite Izuku not moving from his place back flat on the couch until it was satisfied with the depth of its thrusts that nailed that bundle of nerves with every second thrust. Izuku keened with his head thrown back and his fist pulling furiously at his throbbing prick.
It was building, and Izuku could not hold it off any longer. He came. The fucking did not stop though and Izuku whimpered as his hole went sensitive until finally the cock thrust in all the way and throbbed filling his channel with hot, wet cum.
Izuku lay rather stunned on the couch for some minutes before he felt cum leaking from his ass.
In a rush, he jumped up kicking his shorts off of his ankle before waddling quickly to the bathroom. Once there a little investigation revealed that nothing was leaking from his hole despite the feeling, though the rim was puffy and sensitive.
While there might not be cum leaking out of him, Izuku did have his own cum all over his stomach, chest, and thighs from what was undoubtedly the best orgasm of his life so he stripped off his baggy t-shirt and hopped into the shower.
~~~~~
Katsuki lay panting beside the Deku doll.
That had been . . . the best orgasm of his life. Now what he wanted was to pull Deku into his arms for a snuggle and a nap but the doll was cool to the touch and Katsuki could not bear that.
Best to get up and to get clean rather than lying around wishing for things he could not have.
Swearing, Katsuki stood snatching the doll up as he headed to the bathroom. Might as well clean it up before anything got gross and dried.
~~~~~
Izuku stood under the spray, eyes closed, face turned up into the water.
Wow. That was something. Should he be worried?
Loose and dreamy from the orgasm, Izuku couldn’t find it in himself to be too worried. Well, not worried enough to tell anyone about it anyway.
He mumbled to himself, until he felt a shower jet on his ass. And then fingers in his ass holding his hole open for water to gently rinse him out.
His eyes widened as he realized that he was being cleaned out.
~~~~~
It could have been a one time thing. But it wasn’t.
Izuku found himself being fucked by what he came to think off as his Kacchan-ghost. Shut up, it wasn’t like anyone could hear his private thoughts.
It was worrying but it felt so good, Izuku couldn’t bring himself to even try to stop it.
~~~~~
Katsuki found that using the doll to vent his sexual frustrations surrounding Deku only worked until he got cleaned up before coming back in full force.
Morning was the easiest time to use it and use it he did. Every morning. The evenings were good too, especially if Deku had been especially annoying or adorable that day. But never past 9pm, proper sleep was essential to maintaining peak physical condition.
Thankfully, Katsuki’s off days often coincided with Deku’s allowing them to spend time together which was wholly satisfying and maddeningly teasing all at once. When they did not and he didn’t have plans with his other friends, Katsuki planned to indulge.
~~~~~
Izuku came awake like he did every morning after that first ghost experience, with the wonderful feeling of fullness as he was fucked into consciousness. He moaned, arching, it didn’t matter how he slept, side, back, or stomach, he woke up full of cock because apparently his Kacchan-ghost was an early riser.
He sniggered to himself.
Despite the fact that he could feel the phantom touches even with clothes on, Izuku took to sleeping naked to more fully appreciate the wake up call.
Rolling to his knees, spread wide, Izuku wished that he could properly push back on the cock spreading him open but nothing he did affected the tempo of his fucking. He just had to take what was given to him.
He moaned, and jacked himself in time cumming just before a phantom load was shot into his ass.
Another great morning.
~~~~~
The evening wasn’t like the clockwork of the morning were he would be fucked without fail. After patrol, he’d head straight back to his apartment eager to find out what the evening held.
Some days, there was nothing. That was always a bit of a let down, but it also increased his anticipation for the next time.
Other nights, it was only teasing touches. One night, Izuku writhed on his couch, uncaring of the movie he’d put on to watch as his nipples were plucked, pinched, sucked, and twisted. He noticed very early that the ghost hands rarely touched his cock, seeming to prefer playing with his nipples, his hole, and occasionally his balls, so he had to finish himself off. Not that he minded.
Another night, his hole was mercilessly played with, phantom fingers pushed in scissoring pulling his hole open, teasing the rim. It went on for what seemed like hours, adding more fingers, stretching him out, getting him to gape.
But his favorite always seemed to come on the evenings when the day had been extra hard, and he really needed to get out of his own head. He was lucky if he got home before he felt wetness at his hole before the ghost dick was pushing in fast and insistent.
No lazy morning tempo, but a good hard fucking that usually had Izuku trying to slither out of his clothes while draped over the couch, table, or counter while he held on for dear life as his insides got rearranged.
It was one of those nights and all he’d been able to do was unfasten his pants and get them shoved down to his ankles before he flopped over the back of his couch and took the dicking of his life. He whined and moaned and found that he couldn’t work up enough strength to push back and get ahold of his cock.
Izuku found that that didn’t matter when he came unexpected and untouched onto the upholstery with a cry of “KACCHAN”.
He collapsed further onto the couch as he was fucked through his orgasm before his ghostly partner finished with a few more hard thrusts.
Fading fast, Izuku kicked off his shoes and pants before rolling down onto the couch with the throw blanket feeling loose and drained and perfect.
That was just what he needed.
~~~~~
Katsuki was disappointed that Deku had been called in so that they couldn’t spend the day together, but it did mean that he could spend as long as he’d like with the doll, in the doll.
Katsuki smirked.
He put together his usual off-day breakfast, large and heavy on the protein, before fetching the doll from his bedroom and sitting down. He pulled out his already hardening cock, jacking it to full hardness with slick before settling the doll in his lap and thrusting his way in.
Once Katsuki’s cock was seated fully, he turned his attention to his food. What he won’t give to have Deku speared on his cock while he went about everyday things. Well if he couldn’t have that the doll would have to do.
~~~~~
Izuku was grumbling into his coffee about being called in on one of Kacchan’s off days but there wasn’t any way to reschedule. The other thing he wanted to grumble about was that his ghostly lover hadn’t woken him in his usual way so Izuku was feeling a little too keyed up and empty while riding the train.
Just as he took another sip of his coffee, Izuku felt a blunt, wet pressure at his hole.
He choked.
Covering his cough, Izuku ducked his head as his eyes went wide and wet while his hole was filled in a few short thrusts.
This was the fullness he had missed waking up to, but to have it happen while he was in public!
Izuku stayed curled in on himself, his hole clenching greedily, while he braced to be fucked on this thankfully uncrowded train.
Only, he wasn’t.
The fullness was there holding him open, but it wasn’t moving. Izuku squirmed. It was so good that he was half hard already, but it didn’t move .
Finally, Izuku uncurled and resumed drinking his coffee trying to pretend that he wasn’t full of ghostly dick and loving it. He knew that his face was red but he hoped that his fellow passengers would put that down to his hard coughing fit.
At his stop, Izuku spared a moment to be thankful that his coat was long enough to hide his semi as he tried to walk as normal as possible while feeling so stuffed. This must be what walking with a fat plug in feels like, Izuku thought.
Just before he made it to the meeting room, he felt the cock pull out. And as he settled in his seat Izuku mourned its loss as his hole felt like it was gaping.
~~~~~
Having finished his breakfast, Katsuki pulled the doll off his dick. He was so hard, but he loved the tease of just staying that way so he cleaned up his dishes and set his kitchen to rights before heading for his treadmill.
Usually, Katsuki would run through his neighborhood but today with his persistent hard-on he was not fit for the public.
Once finished with his run, Katsuki stripped and headed for the shower bringing the doll with him. After a quick shower, he filled his tub pulling the doll in with him.
He pumped his dick which had flagged from inattention back to full hardness before pushing into the doll in his lap again.
Katsuki loved the thought of sharing a tub with Deku. He’d probably think it was romantic, Katuski wouldn’t care just so long as he got to snug his cock up inside him.
~~~~~
The meeting was almost over, having thankfully not taken as long as they’d expected. Izuku had already finished his contribution when he split open once again. It was all he could do to keep himself from crying out.
The presenter went on thanking everyone for their hard work, while Izuku sat stiff and glassy eyed full and fully hard once again.
Squirming in his seat while trying not to be obvious, Izuku needed to be fucked but this phantom prick just wouldn’t move!
Suddenly, everyone was standing, Izuku shot to his feet, mumbling polite excuses before rushing out. He had planned to surprise Kacchan if they finished early but could he do that while he was full of this ghost-Kacchan cock? It felt like electricity in his veins, the thought of being full but with Kacchan there .
Nothing seemed more important in that moment than to get to Kacchan.
~~~~~
Standing up from his bath, Katsuki pulled out of the doll and set it aside to dry off. He had a movie he wanted to watch.
~~~~~
Halfway to Kacchan’s apartment, Izuku felt the cock pull out.
He broke into a run, making it into the elevator before being filled once again.
The cock thrust in and out a couple of times before settling in and going still, leaving Izuku gasping and panting as the elevator doors opened onto Kacchan’s floor.
Struggling out of his coat and fumbling with the spare key Kacchan had given him, Izuku burst into the apartment panting.
There was Kacchan shirtless on his couch with someone in his lap! No, not some one , some thing . A doll, a doll that looked like him!
Izuku’s wide eyes met Kacchan’s startled gaze over the doll’s shoulder.
They stared at each other for an endless minute before Kacchan shifted and Izuku fell the cock in his ass shift as well.
Dropping his coat, Izuku kicked the door shut while unfastening his pants, shoving them and his underwear down to his knees, his hard cock springing free, before turning and bending at the waist holding his cheeks to present his hole to Kacchan.
~~~~~
Katsuki was frozen with the doll in his lap. Oh god, Deku’s seen the doll. The doll that looks just like him!
Despite the horror of this thought slicing through his mind, Katsuki couldn’t help staying hard with the sight of Deku flushed and flustered and in the flesh. He shifted.
Suddenly, Deku was a whirl of motion that ended with Katsuki getting an up close look at Deku’s plump and freckled bare ass. The rim of his hole was gaping wide showing his pink insides.
Katsuki could not help thrusting up into the doll, but his mind re-fired when Deku’s hole spread while he let out a moan.
Ripping the doll from his cock, Katsuki heard Deku yelp as he stood, catching him by the waist preventing him from falling on his face. He spun Deku around pulling him to his bare chest with one arm the other hand reaching up to tangle in green curls at the back of Deku’s head.
“Deku,” Katsuki growled.
“Kacchan,” came the breathless reply.
Staring into Deku’s wide eyes, Katsuki couldn’t help kissing him.
~~~~~
Izuku was drowning.
Drowning in the wonderful feeling of Kacchan kissing him. Kissing him like he could just eat him up, and Izuku wanted to be eaten.
More than that, Izuku wanted to be full. Finally full not of air or of ghosts, but full of Kacchan!
Izuku pulled his mouth back to gasp, “Kacchan, please.”
Kacchan buried himself in Izuku's neck, kissing and nipping. While the hand at his waist moved down and around grasping a hand full of his needy ass.
“Gahhnaahh, Kacchan please,” Izuku whined, “I’m so empty, Kacchan.”
Kacchan reared back, eyes dark and wild. Staring.
~~~~~
Katsuki’s lust-addled brain usually worked faster than this but Deku was there whining for his cock.
Suddenly the fog cleared and Katsuki stepped back a pace gripped Deku’s shirt and skinned it off him. Thankfully, Deku was quick because he heeled off his shoes just in time to be pulled from his pants and underwear leaving him naked except for his socks.
Katsuki plopped back onto his vacated spot on the couch with the warm and wriggling Deku spread over his lap.
Deku giggled and kissed him before pulling back and pushing the bottle of slick into his hands.
“Come on, come on Kacchan. You’ve been teasing me all day!”
“Have I?” Katsuki fumbled with the bottle, “Wait, have you been feeling it this whole time?”
Deku blinked up at him replying, “I don’t know. I’ve been feeling ghost touches for a few weeks now.”
They both looked over at the abandoned Deku-doll laying on the floor.
“That’s about when I got it,” Katsuki confessed. “I’m sorry, I had no idea. . .”
Deku cut him off, “No, don’t be sorry! I-, I loved it. It felt so good, Kacchan. And, well, I wanted it to be you so bad.”
Deku trailed off and Katsuki had to kiss him again.
But Deku pulled back too soon crying, “Are you ready Kacchan?” And then not waiting for a reply before lining Katsuki’s cock with his hole and plunging down on it.
Moaning, Deku worked himself down onto Katsuki’s dick while Katsuki grit his teeth to keep from cumming right then. He had thought that the doll was a good approximation of Deku, but nothing had prepared him for how tight and warm and wonderful it was to be inside his Deku.
~~~~~
Kacchan was inside!
He was a perfect fit, hot and thick with his hands gripping at his hips.
Kacchan sat unmoving but Izuku couldn’t wait any longer, he began to bounce fucking himself on Kacchan’s perfect cock.
~~~~~
Katsuki could not remember why he thought the doll was even serviceable because here was Deku fucking himself, using Katsuki to get off and he had never been more turned on in his life.
He went to reach for Deku’s cock that was pressed between them only to have Deku bat his hand away.
“No!” Deku gasped, “No, I can come on your cock. I want to.”
Groaning, Katsuki buried his face in Deku’s neck and planted his feet so he could fuck up into him even harder.
Suddenly, Deku plunged down freezing, the walls of his ass clenching Katsuki’s dick in a vice as he came between them. Katsuki watched him, awed before jerking up twice more and filling Deku with his own spend.
After a few minutes of catching their breath, Deku gingerly slipped off Katsuki’s lap but Katsuki refused to completely relinquish his hold on him. Once he was up, Katsuki turned and stretched out on the couch pulling Deku down to sprawl on top of him before gathering him close for a cuddle.
“Oh,” Deku began nervously, “I thought you’d want to get clean right away? You always seemed to before.”
“Mmm, yeah. I wanted to clean up my toy but I’d rather cuddle my boyfriend first,” Katsuki said feeling suddenly vulnerable.
Deku’s face blossomed into a sunny smile and he leaned down to kiss Katsuki before snuggling close.
“That sounds perfect.”
As they drifted off, Katsuki glanced at the discarded doll then back to the warm beauty in his arms. There wasn’t so much of a resemblance as he’d thought, but since it had led to this he figured that it did deserve the five star review he’d leave.
The End.
