This isn’t necessarily a lemon. More of a lime. Basically, Error is in heat and needs to deal with it. Though the way he deals with it is instead masturbating to Y/N while she’s in the shower, imagining what he could do to her. At the end, there’s a slight twist… 

Error woke up with a quiet groan. His eyesockets were closed, his face flushed with a bright yellow. “Dammit…~” He cursed. He couldn’t help but let the slight purr in his voice escape. “Fucking heat…~” 

It was heat month for him, starting today. He opened his eyesockets slowly, lust filling them. He didn’t even comprehend how he had already stood up and was walking over to his lover’s room. He quietly walked in, making sure she wasn’t inside or awake. He released a small breath before tensing once more. 

He could hear her in the shower.

Error cursed again, though it was much quieter than before. ‘Guess I’ll have to sneak in…~’ He thought to himself. He looked around, a small bulge appearing through his shorts and boxers. God, he could just see the pure innocence his lover had. It wasn’t helping his heat.

He walked over to the bathroom door silently, listening as his love sang softly. ‘Fuck, Y/N…~ My little, innocent, Doll…~’ He sighed softly. The bulge in his shorts grew as he thought about her.

It was eventually to the point where he couldn’t help himself. He palmed his bulge through his shorts with his hand, leaning slightly against the door. Luckily, Y/N couldn’t hear him. Error released a breath as he continued. 

Soon enough, Error couldn’t take it. He slowly slid down his shorts and boxers, his yellow cock springing free. He lightly took ahold of it in his hand, another breath being released. His blush rose, moving his hand so his finger teased the tip. Error shivered quietly, imagining it was Y/N touching him with innocent curiosity. His hard cock dripped precum onto his finger.

‘Sh-Shit…~’ He mentally cursed. He slowly moved his hand to wrap around his length, smirking to himself. Error imagined feeling Y/N’s warm skin running along his member, the slight wetness of her entrance coating it. He cursed once more for what seemed to be the millionth time, moving his hand faster. 

He imagined seeing Y/N’s face contort from pain to pleasure almost instantly, her hands tied together above her head. This made him go faster. Error didn’t even realize Y/N had turned off the shower.

Error quickly came, crashing for a moment. He quickly rebooted, his cock twitching slightly. He controlled himself from moaning loudly, not wanting Y/N to hear him despite the fact she probably already could. When he finished cumming, Error shivered. 

But was then quickly faced with a confused Y/N.

“Error what the fuc-”
