Sweetheart - Part 4

NOT SAFE FOR WORK!!!

─────

A week after Deku left, Katsuki got his first gift. He came home from work to find it waiting at the apartment complex's reception, a huge wicker basket stuffed full of the freshest fruit and vegetables, with a card attached telling him it was a subscription service. Every fortnight another huge basket would show up at his door.

Katsuki blushed when he read it. The damn nerd was a sneaky bastard, already finding loopholes in his “no money” rule.

He pulled out his phone, snapping a picture with the basket and sending it to the nerd. He hated his deer-in-headlights look, hated how pink his face was, but the nerd had made it abundantly clear that he liked that expression the best.

“You're walking a fine line here, nerd,” he typed out. “But I'll accept, they look really tasty.”

A few weeks later, it was a suit. Pure black, the softest material he'd ever owned, with a white shirt and a deep green tie. It fit him perfectly, because of course it did, and he stood awkwardly in front of a mirror to take a photo, running a hand through his hair. He'd just had his second spa appointment, at Deku's insistence, and Katsuki was not nearly modest enough to pretend he didn't look damn good.

“Wow, Kacchan!” Deku sent back immediately. “So handsome! Wish I was there!”

They settled into the arrangement easily, with Katsuki sending various selfies when the nerd requested (or when he felt like he was looking particularly hot – he wasn't stupid, he knew why Deku wanted photos) and Deku showering him in gifts.

For the first time since high school, Katsuki found himself with a savings account. Between the clothes and the groceries the nerd insisted on sending him, his bills had dropped significantly lower, and he was enjoying watching the number in his account grow. It was slow, but it was steady, and he was starting to have some hope that when the time came to leave Miruko's side and forge his own way, he might actually be able to hold himself over.

It took about six more weeks for the unassuming brown box to arrive, a little note stuck in the top.

“If you send me photos with this one, I'll lease you a new apartment ♥”

There was no way.

He opened up the paper with shaking hands, eyes landing on a shiny green... God, he didn't even want to think the word “dildo”. He wasn't an idiot, he'd known from the outset that the nerd's feelings were sexual in nature, even though he'd assured Katsuki he wasn't going to ask for sex. It wasn't like he was demanding photos with it, either. He'd never demanded anything.

His apartment was pretty shit, though. Things were constantly breaking, and it took forever to get the landlord to fix them each time. Deku had offered to replace them, when he was complaining on the phone one night, but the damn furniture came with the apartment, he couldn't do shit.

Except move, as the nerd knew well.

He grabbed his phone and started a video call, unsurprised to find the nerd's face was a little nervous when he picked up, rather than his usual beaming smile.

“Are you serious?” he asked with a scowl. “You're trying to bribe me into shit, now? When did bribery become a part of the deal?”

“You're allowed to say no!” Deku assured him. “I just... Well, you're hot, you know? And, well... It would be a fun photo to have, if you know what I mean.”

“You're seriously willing and able to drop rent money on a dumb photo?”

“It's not dumb,” Deku pouted. “And yeah. I'll... I'll lease it for a month for every photo!”

Katsuki snorted at that, eyeing the toy just beyond his screen with critical eyes.

“I want a penthouse,” he teased, as he picked the thing up and showed it to the camera. “Fully furnished, the works.”

“That's gonna cost you more,” Deku smirked, leaning in closer to his webcam. “What have you got?”

“I'll do it right now,” he said quietly, swallowing hard. “You can watch.”

“Fuck,” Deku hissed. “I'll buy you the fanciest damn apartment in the city.”

He set his phone up beside the bed, far enough back to give Deku a decent view of everything... important. He dug a bottle of lube out of his bedside table, coating his fingers in it and trying to forget about the nerd watching as he slipped one into his hole.

It wasn't like he'd never fingered himself before – a guy gets curious, after all – but the knowledge that he was going to stick something else in there made him nervous.

“Relax, Kacchan,” Deku instructed, a hint of nerves in his voice too, as he waited for Katsuki to yell at him for speaking. When the anger didn't come, he continued in his stammering tone. “Go nice and slow, I want to watch you take your time, okay?”

Katsuki nodded, tossing his head to the side as he slowed his pace a little, pumping his finger in and out. The first one never felt good, not until he loosened up a little, but he was used to getting it over with.

“Slower, Kacchan. Let me see you tease yourself, let me see you begging for more.”

With a little huff he slowed right down, rubbing his fingers across his hole and occasionally slipping one in.

“Touch your dick, Kacchan. Rub your thumb over the end, just lightly.”

“Wasn't aware this was an interactive experience,” he grumbled, reaching for his cock all the same. “You just gonna sit here and tell me how to jerk off? Been doing this shit since I was a teenager, nerd.”

“I wanna see you play with yourself they way I would play with you,” Deku told him bluntly. “Wanna see you dripping wet and desperate before I finally fill you up.”

“Good luck, nerd. I'm not a damn bottom.”

“Anyone who has to say they're not a bottom is definitely a bottom.”

“Fuck off.”

“Your thumb, Kacchan. Gentle.”

He ran the callused pad across his head, hissing as his hips bucked up a little, his finger moving in and out again at its slow, steady pace.

“Another finger, Kacchan. As slow as you can, until you can't wait anymore.”

“Can wait all damn day if I want to.”

“Uh-huh. Slow, Kacchan.”

He wiggled a second finger inside, pulling a face as he made it fit, shifting his lips a little to get a better angle. He moved slowly, just like the nerd said, stretching himself wider as he moved his hand in little circles. When he curled them a little and hit the spot he wanted, his hips bucked again, his cock sliding through his fist, and he heard a little huff come from his phone.

“You look so good, Kacchan,” Deku told him. “So gorgeous. Stroke yourself a little – just a little. Don't go getting off before the main event.”

“Hah, you think I can't go more than once?” Katsuki snorted. “Someone needs to work on his stamina.”

“And someone is gonna get a spanking if he keeps answering back like that.”

A little gasp escaped Katsuki's lungs, sinking a little lower onto his fingers as he stroked himself, and he heard a distinct laugh from Deku.

“You like that idea,” Deku chuckled. “You bottom.”

“Fuck you.”

“Yeah, right.”

Katsuki growled, but continued stretching himself regardless, wondering – not for the first time – how the hell the nerd went from his friend, to his enemy, to his rival, and now to whatever this was.

Deku had been silent for a whole three minutes by the time Katsuki noticed it, glancing over to make sure the call was still connected. He was still there, watching attentively, leaning on his elbows with his hands over his mouth.

“It's even weirder if you don't talk,” Katsuki groaned. “Go back to the other shit.”

“Are you sure?”

“Fucking yes, nerd, don't question me.”

“That's not very nice, Kacchan. After I bought you a pretty new toy, too. Look at it there beside you, isn't it nice? It's such a pretty colour, isn't it? Look at it, Kacchan.”

Cursing under his breath, Katsuki turned his head toward the toy, glimpsing the shiny green material again. What was the thing, anyway? Weren't they usually silicone or some shit?

“It looks hard,” Katsuki grumbled.

“So are dicks, when you use them right, Kacchan.”

“You know what I mean, fucker.”

“You want to try it out that bad?” Deku teased. “Go on, I bet you could fit it now. Use lots of lube!”

“Fuck-”

“Nuh-uh, don't talk, just do what I ask, Kacchan. Save your pretty voice for the moaning.”

Seriously, when the fuck did the stuttering nerd get so confident?

Katsuki lubed the toy up obediently, holding his breath as he reached between his legs and rubbed it over his entrance. Now that he was a little looser, it felt much more pleasurable than awkward, and he found himself sinking down onto the toy before Deku had even told him to.

“Aww, look at my eager baby,” Deku teased. “Taking it so well! Does it feel good, Kacchan? I bet it feels amazing, filling you up just right. Wish I could be there to help, I'd make you feel amazing.”

Katsuki groaned, thrusting down on the dildo, and he heard Deku's breath hitch.

“God Kacchan, you look so good. Sit up for me, baby. Turn this way.”

“Haaah?”

“Lean against the wall there, I wanna see you playing with yourself, wanna see my present inside of you.”

With a frustrated groan, Katsuki turned himself around, pointing his ass at the camera and propping himself up on pillows to find the right angle again. Deku watched eagerly as he began to pull it out, reminding him to slow down and take his time.

He had a clear view of the toy emerging from Katsuki's ass, and when Katsuki squirmed around it, searching for friction, he seriously considered jumping on a plane then and there to go help.

“Pinch your nipple for me, Kacchan.”

“Haah?”

“Come on baby, just a little pinch.”

Katsuki hissed a little as he shifted, fumbling his way up to his chest. He squeezed lightly, a long moan escaping him as he started to push the dildo back in, and Deku bit down hard on his lip.

“Okay, you can go faster now, baby. Show me how bad you want it, show me how much you like my gift.”

Katsuki was too far gone to care about the embarrassing words, too occupied by the pleasure washing over his body. He pinched again, a little harder this time as he thrust the toy in, no longer able to maintain a steady pace. His hand shook as he moved it in and out, fucking himself hard and fast, but when he reached for his cock, he heard the stern voice again.

“Don't touch, Kacchan. Not until I say you can.”

Katsuki whined wordlessly, but he took his hand away, moving it back to his chest to pinch at the other nipple this time. He threw his head back, eyes closed and gasping for air, and Deku could only watch, spellbound, as Katsuki came all over himself.

“I guess that's one way,” he smiled wryly, when Katsuki cracked an eye open. “Not allowed to touch, so you cum without touching. I guess that's fair.”

“Shut up, nerd.”

“Go get cleaned up, Kacchan, before you're too sleepy.”

“Fuck you, I told you I'm gonna do it again.”

“Wh- I- R-Really, Kacchan?”

“Mmm, just need a sec.”

He sighed as he relaxed back into his pillows, stretching his wrist where it was cramping from his thrusts. Deku took in every inch of the beautiful scene, of Katsuki covered in fluid with sleepy eyes, the green glass dildo still sticking out of his ass a little.

“I wish I could kiss those cheeks,” Deku mumbled, blushing when he realised Katsuki heard him. “You look so cute like this, Kacchan. Laid out all comfy and spent.”

“Take a screenshot,” he grumbled, flinging an arm over his eyes. “Too tired to take a photo.”

“That's a good idea. Move your arm for me, let me see your pretty face.”

“Do I have to?”

“Please?”

Katsuki huffed, peeking out from under his arm, and Deku took a couple of pictures of the cute gesture while it lasted.

“I want a big kitchen,” he grumbled.

“Only if you cook for me when I come visit.”

“Fine.”

He moved his arm away, giving Deku a clear view of his little pout, and he took a dozen screenshots just to be sure they saved.

“So handsome, Kacchan.”

“Duh.”

He reached between his legs, pressing at the end of the dildo and humming to himself as if he were contemplating something.

“Did you pick it out yourself?” he asked, toying with the end and making tiny, shallow thrusts. “Is it green so that you can pretend it's you?”

“So you wont forget where it came from,” Deku corrected him. “It looked pretty, too. Like you.”

“Ugh.”

Deku smiled at him, watching the flagging dick quickly start to perk up again.

“I'm gonna come visit next week,” Deku informed him, glancing off to one side at his desk calendar. “I have some free time, I'll make the trip up and help you move.”

“You're gonna find me a sweet-ass penthouse in a week?” he snorted.

“If I see you cum again tonight I will.”

“Freaky nerd,” Katsuki huffed. “Fine, my shitty oven broke again anyway, takes them at least three weeks to get it fixed.”

“You can touch now,” Deku smiled. “Show me how much you want a nice new oven, baby.”

“Don't say it like that, asshole.”

He wrapped a hand around his cock, feeling it quickly return to full mast as he ran his sticky hand up and down. He was covered in sweat, cum, and lube, it was all pretty disgusting really, but he could see it in the nerd's face that he loved the mess.

It only took him a couple of minutes to be squirming again, listening to Deku mumble praises under his breath unknowingly and finally realising that, fuck, he kind of liked it.

He came over his hand, more of a trickle than a spurt this time, and Deku sang his praises as he fell back on the pillows again.

“So impressive, Kacchan! Go run yourself a bath and get cleaned up, okay? I'm gonna start looking at apartments.”

Katsuki snorted, fumbling for the phone and holding it up closer to his face.

“You're gonna go jerk off,” Katsuki accused. “I'm not stupid.”

“Kacchan!!”

“It's fine, you can,” Katsuki shrugged. “And it doesn't have to be a penthouse.”

Deku giggled at him, and Katsuki cracked a tired smile.

“Just want a nice kitchen and shit that doesn't break all the time.”

“I'll find you something amazing, Kacchan. I promise. Go take care of yourself, I'll check in on you soon!”

“Have fun, nerd.”

With a last little wave he disconnected, tossing his phone aside and sighing. It was tempting to just go to sleep where he was, but the mix of fluids was just a little too gross to put up with while he napped.

Instead he pulled the dildo out, cursing at himself for doing it too quickly, and headed for the bathroom.

Dumb nerd was probably moaning his name by now.
