Chapter Text
Laying on his side , sakutaro had his nose buried in his phone which was propped up by yuuya’s chest . His lover was doing the same , facing sakutaro and holding his phone to top of the others head as he scrolled . Their feeds were drastically different , and not just because of the difference of app usage . sakutaro scrolled through gore and pictures of others self harm on twitter , meanwhile yuuya spent his time watching movie trailer and looking at movie reviews .
This was what time together looked like for them , silently enjoying each others company while focused in their own activities and enjoyments . It was beneficial for them both , as neither were the most talkative and mutually enjoyed the silence .
After awhile of scrolling through his feed , sakutaro laid eyes on a more suggestive photo , of one holding a knife to anothers wrist .
Sakutaro cuddled up against yuua , burying his face into the others chest as he shuddered slightly , imagining yuuya being the one with his knife to sakutaro’s throat . the shudder caught yuuya’s attention , and the boy set his phone down to sit up on his elbow slightly , gazing down at his boyfriends head . he gently grabbed the others chin to make him make eye contact , gazing at his partner .
“What.”
He asked blandly, squinting a little in confusion . sakutaro wasnt one to show his embarrassment , or be cuddly either . yuuya was the cuddly one , while sakutaro enjoyed kissing more than anything . was he horny or something ? yuuya couldnt name a single time sakutaro had evenr shown and sexual interest , other than asking him to cut him . oh , was that what he’d been looking at ? again ?
“Yuuya. I want you to cut me.”
Sakutaro looked serious despite the tint in his cheeks , expression flat despite the obscenity that hat left his mouth . it wasn't unusual in their relationship , something sakutaro asked for often and yuuya declined just as often . yuuya loved him , and didnt want to harm him when the other was feeling self depreciative or hating himself . he wanted to hurt him and get a good reaction out of it , while the other could mutually enjoy it in his own twisted sense .
“You want me to do that now?”
“Yes”
Yuuya sat up without missing a beat , as did sakutaro . the taller one hummed softly , one hand sliding to sakutaro’s back as the other cupped his cheek . and then yuuya kissed him , tender and affectionate . he loved sakutaro morishige more than anything else on this earth , and he was willing to do most anything for him . Yuuyu kissed sakutaro , slowly starting to lay him against the bed before he felt a hand at his chest , pushing him off .
“Knife.”
Sakutaro stated flatly , and yuuya gave a breathy chuckle .
“Right.”
Kizami moved to kneel on the floor , pulling out from under it a box of knives . he called it his knife collection , but sakutaro called it one of two murder boxes that yuuya kept in the house , the other being a variety of tools you would find strange if not thinking of murdering someone . yuuya grabbed a bowie knife . had reserved this knife for sakutaro over the years , to use on him and him alone . while he did have a few favorites he’d grown a fondness for this one over the others , because the every once in awhile that he did agree to use it on sakutaro they tended to feel closer than before .
Yuuya rested himself against the beds headboard , gesturing with the knife for his lover to place himself in his lap and get comfortable . sakutaro did so , using his hands to scoot himself back into yuuya, back to the others chest . yuuya gently placed his left hand to sakutaro’s waist , knife hovering over his right thigh as the other pulled down his skirt . he felt odd having his tan thighs on display to yuuya , barely any scars there . sakutaro was an arm cutter , the only scars on his legs were from yuuya the few times the other agreed to cut him like this . usually he didn't go along with the idea .
The two of them sat there for a long moment as yuuya admired sakutaro’s thighs . He loved every inch of sakutaro , and despised that there was always something about expressing it that irked him . He wasn’t aware of how toxic his masculinity could be , oblivious to the fact that he wouldn’t express his attraction because he felt it made him weaker .
suddenly , yuuya leaned in to sakutaro’s ear , nipping at it as he dragged a shallow line across the boys thigh . his eyes were quick to watch , admiring the way crimson red flooded the width of the cut. in response , sakutaro exhaled through his nose and leaned his back against yuuya , body melting into the other . he had to resist the urge to grab yuuya’s hand and dig the knife deep into his thigh , a spur of the moment thought that came to him . yuuya cooed assurance , making sure continuation was okay before he dug the knife into him and yanked it across , making a thick cut in sakutaro’s skin . sakutaro’s breath remained steady , but his hands moved to yuuya’s wrists and gently squeezed them in response . kizami let out a low chuckle at such an action , amused with the fact that he’d gotten sakutaro to react . usually the other was completely still during things such as this . he ran his left hand downs sakutaro’s side , letting it wander to his inner thigh . he grabbed and squeezed before tracing a heart into the other with his thumb for a reaction , watching his face as it burned up . The actions made sakutaro bite his lip , eyes fluttering shut and thighs tensing ever so slightly with arousal . Yuuya knew how to press buttons sakutaro didnt even know he had .
The two sat like that for a long while , until the room reeked of blood and sakutaro winced when he moved his leg , coated in overlapping lines . Yuuya didnt care for neatness like sakutaro did , instead leaving messy , fast cuts rather than the slow and methodical ones sakutaro would do himself .
Starting with a small objection from sakutaro when yuuya went to cut again , they wordlessly began their cleanup ritual . yuuya carried the other to the bathroom and praised sakutaro for sitting so quietly as he patched the other up . Sakutaro smiling ever so slightly , not so much as wincing as yuuya went over each mutually thick and deep cut with ointment before applying gauze . The cutting meant sakutaro got to be spoiled for a few days until they scabbed over , so more like a week this time . Then yuuya would bring sakutaro back to bed and they would sleep , knife cleansed and sheathed before it had been placed back into the box .
