day three: toys 🧸 👀 #bkdk #bakudeku

katsuki had been told that they were going to put up christmas lights tonight. it meant no more decorating, so it worked out.

what he didn’t know was the the lights would be used in…other ways.

it started off so innocent. katsuki came in from patrol, saw that izuku had already gotten the lights out and ready, so they quickly went to work.

they started in the main room of the apartment, izuku gathering all of the strings and handing the bundles over to katsuki as he used Float to get to the highest points and wrap the lights around. honestly it was easy work, with more than 3/4 of the lights done after 1.5hrs.

“kacchan, let’s take a break.” izuku said, walking to the kitchen to grab the now half-empty bottle of wine they had been sharing all throughout the night.

“we’re almost done nerd, let’s just finish now before i get bored.”

“but kacchan, i’m already bored!”

katsuki could hear the whine clearly from the other side of the room, rolling his eyes as he kept putting up lights.

“it was literally your idea deku. don’t bitch out on me now.”

katsuki didn’t need to turn to see the pout that had certainly grown across izuku’s face.

he could feel it, those big round eyes boring holes into his back. the whines got louder and louder as he kept ignoring the greenette, eventually giving in and dropping the bundle of lights he held.

katsuki moved to the couch, watching izuku’s face light up as he got closer.

but instead of reaching for his boyfriend, he grabbed the bottle of wine off the coffee table and took a biiiiiig swig before returning it to its spot.

“you can sit there and whine, deku. i’m going to finish putting up the lights.”

“though i don’t know what to do with these big round ones, so you figure that out whenever you stop laying around.”

izuku looked down at the lights in question, a long string of orange and green spheres that were just a hair smaller than izuku’s fist.

and suddenly, he knew exactly what to do with them.

a wide grin split izuku’s face and he bounced up from the couch, practically skipping to their room. katsuki just rolled his eyes again and went back to work. there wasn’t much left now, though it would’ve been done quicker with two people.

oh well.

katsuki didn’t notice that izuku had come back into the room, too engrossed in the best way to hang the lights across the bannister of the stairs. he also didn’t notice the new sounds coming from the couch in the living room at first, too busy muttering under his breath.

“nngh, so warm,” katsuki froze, ears straining for a moment from the top of the stairs.

“ahh, yes, that one’s in,” soft squelching could be heard over the moans, almost lost behind the sudden rush of blood that went past bakugo’s ears and straight to his dick.

/fuck the lights/ was the first thing that came into his mind as he not-so-calmly walked (read: ran) down the stairs to enter the living room.

he could not have been prepared for the sight that was waiting for him there.

izuku was spread out on the couch, laying on his back with his ass hanging over the edge. he had pulled the coffee table just a hair closer and was resting his toes on the wood, legs spread side as his hands worked around his hole.

it was what was inside that make katsuki gape.

those lights, the orange and green spheres, had been worked halfway into izuku’s ass. bakugo couldn’t tell how many midoriya had fit in there so far, but the way he was sweating and panting —and the way his cock stood straight up, leaking— made him guess it was more than a few.

as katsuki approached izuku gave him a sly smile, maintaining direct eye contact as he began to press another against the puckering rim. the blonde didn’t know whether he wanted to watch his boyfriends face or his ass more: his face was flushed, mouth hanging open and tongue +

lolling out to the side. his ass was shiny and glistening, bright orange and green lights shimmering off all the lube he had used in the first place.

quiet little sounds escaped his mouth, a chorus of ‘ahs’ and ‘ooohs’ and ‘nghh’ and the occasional lewd moan.

from his current position katsuki could see it all, could see the way izuku’s muscles strained around the glass ball, eventually giving way and spreading around the widest part.

“fuck, izuku. that’s not what those are for and you know it.” katsuki’s voice had lost all of it’s +

venom, tone close to quivering as he watched his boyfriends asshole try to push the ball back out. izuku just smiled, bitting his bottom lip and stifling a moan as he pushed it all the way in.

it disappeared inside his hole, leaving nothing but the black cord hanging out.

katsuki moaned loud enough for the both of them, dropping to his knees and palmed both of izuku’s cheeks, pulling them apart to look inside. he could literally see the lights glowing in there, stuffed deep and clacking against each other with every shift of izuku’s hips.

“ahhh, yes kacchan, do you want to put the next one in???” izuku loved the way katsuki’s face hovered so close to his hole and the lights inside. the little gusts of air against his wet hole were absolutely maddening, and izuku’s cock leaked, pre slicking against his skin.

“don’t ask stupid questions deku. of course you fucking idiot. before i do that though…” katsuki’s sentence trailed off and izuku’s moans grew louder as his boyfriend wrapped his mouth around his rim, sucking and licking at the wrinkled skin.

“/fuck/ kacchan, feels so good…” izuku’s moans grew louder and lewder at the same rate katsuki’s mouth moved quicker and sucked harder, tongue wrapping around the cord that hung out, plunging inside to taste, pressing the wet muscle inbetween the warm glass and velvety walls.

he pulled his mouth off with a pop, drool and lube dripping down his chin as katsuki grinned.

“and peppermint flavored lube? really izuku?”

“i knew you would like it,” izuku breathed out, between his own moans as katsuki continued to play with his hole.

“oh i love it. and i’m going to love seeing you stuffed full of all these lights even more.” katsuki tugged at the string, watching with sharp eyes as izuku’s hole widened to accommodate the intrusion.

“and next i’m gonna stuff your stocking with something even more special.”

“though since you couldn’t even wait for me to finish with the lights before you started touching yourself, that means you’re going to have to wait to come.” katsuki had a glint in his eyes that sent a shiver down izuku’s spine, a shiver that quickly +

intensified as katsuki began to pull all of the lights out. slowly at first, eyes glued to the lewd scene in front of him, with less patience and more malice as it went on. eventually he got tired of waiting, pulling the last four balls out in one go as he bit into the flesh +

of izuku’s ass, and bit /hard/.

the shivering turned into full on shaking as the balls were forced out. to go from being so full to being so empty, plus the sweet pain of kacchan marking up what was his, it just pushed over deku over the edge and his body shuddered though +

his orgasm.

he came back down to earth only to hear the disappointed tch coming from his kacchan.

“didn’t i just tell you to wait, deku? sounds to me like you’re asking to be punished.”

izuku couldn’t help the moan that escaped his lips at the prospect of punishment.

oops.

katsuki grinned, shifting his position to bring the glistening string of lights to izuku’s mouth.

“open up baby, time to taste your mess. and then, we’ll start again from the beginning.”

it was going to be a long night. finishing the rest of the lights could wait.
