A/N: I dunno if it's cause I've been reading a shit ton of gay smut lately, but I really think my lemon writing is terrible. Oh well, I'll give the people what they want.

Perhaps you were just a little out of your mind. You had to be in order to do what you were doing. It was pretty crazy, even by your standards.

What was it that you were doing exactly?

Well, you may have accidentally called up your robot friend that was in love with you and asked him to come over and that you urgently needed to speak with him in person about something. You were pretty sure he was expecting a confession. You were actually planning on fucking him, but that idea hadn't really been properly conveyed. Oops. He'd find out soon enough, and you were pretty sure he'd be down for it.

You had good solid reasoning though: he made you very, very, very, horny and you had just happened to accidentally have been watching his show. You figured that there wasn't much of a point in getting off yourself when you could have him there to help you out.

This whole situation was purely an accident, by the way. You continued to tell yourself as much as you heard the knock on the door and opened it without hesitation, revealing a frazzled robotic star standing on your doormat.

He rushed in and took you in his arms, "Darling, what's wrong? Over the phone you sounded so desperate, is it anything bad?"

"No, no it isn't, Mett," you replied, struggling out of his crushing embrace. Time to play the game. "I just really, really need to tell you something, something I couldn't say over the phone."

"What is it?”

You took his hand and slowly stepped backwards in the direction of your room as casually as you could, hoping that he was too occupied with worrying to notice it.

"I, uh, do you remember how, or what you said a few months ago?" So far so good. You'd need to get in front of him soon.

"I say a lot of things, darling. You'll have to remind me of what exactly I said."

He knew what you meant. You knew that he knew, but he was nervous and trying to play it off as being suave. You could tell.

"You know, when you told me that you-”

"Oh, that." He released your handm

It was probably a painful memory for him. You shot him down when he told you. You spewed cynicism out from your mouth in order to discourage his feelings. You weren't ready for him.

You took his hand back into your grasp. "Well, I think I realized that maybe I love you back?" You felt kind of bad. Sure, he was really fucking attractive and he got you all hot and bothered to no end, but you didn't really love him. Not the way he loved you.

He looked at you in bewilderment, ad before he could speak, you crashed your lips upon his own. He reciprocated as soon as he could do so, and you grew more heated and passionate. You turned around and peeked your eye open before shoving him through your open bedroom door.

His eyes shot open in confusion and you locked the door. "I want to go to the next level, Mettaton. You and me, all the way."

"I don't quite under-"

"I wanna have sex. Simple as that." You shrugged off his confusion.

"Oh. Oh my. I didn't think you'd… If it's what you want, I want it." He spoke with finality.

"Perfect. So, if you're really going to do this, I should warn you that it'll be different. I have some rules for you." You stepped forward, forcing him backwards and into a sitting position on your bed.

"Rules?” he asked.

"Number one," you started, grasping his chin firmly, " Don't question me. Second one, don't curse. I'd hate to fuck a little foul-mouthed whore. Thirdly- wait, can you take those off?"

He hesitated, afraid to question you.

"Your arms, Metta. Can they be removed?"

"Yes, I believe so."

"Even better, tell me how."

He walked you through the process of altering his body safely so that his arms were gone and his cock was out. Not that one led to the other, it just happened to be opportune timing.

"Okay, lastly, if you want anything, anything at all from me, you had better earn it. If you break a single rule, I'll punish you. You're okay with all of that?"

He hesitated in answering and you softened, assuring him that he didn't have to do any of it if he didn't want to.

"Of course I want to fucking do this, I've fantasized about it for an e…ter…ni…ty," he stopped his talking as he realized what he had said.

"Oh wow, you're forgetting already? I'm almost tempted to gag you for that," you were over him, looming.

He gulped hard.

"Still, I think I have a better punishment in mind. Get your ass over here."

He stood in front of you and you turned him to face away from you. He tensed as you bent him over, and you assumed that he knew where this was going.

You pulled your hand back and harshly brought it down on his rear. He whimpered and seemed to try and move away.

Slap, slap! Twice more, back to back. He pulled his shaking knees together and cried out.

"I thought you'd handle this better, Mettaton. I'm a little bit disappointed, if I'm being honest." You hit him three times hard. He moaned in pain.

Once more. And this time he actually moaned, lustful and loud. You laughed at him, "You're such a little slut. Perhaps I should leave you like this, just for that."

"Oh, no, p-please, my darling."

"I'm not quite convinced yet." You hit him again and he moaned out loud yet again.

"O-oh, darling, please," he nearly begged.

"Please what? I don't know what you want."

You hit him again and he cried out loudly, nearly falling before regaining as much of his composure as he could.

"Did you just?" You looked at him for confirmation and received it. "I can't believe you came so easily. You really are a slut, aren't you?"

"Only for you," he insisted between panting breaths.

"Yeah, right. I'm sure. But I didn't give you permission, now did I?"

"…No," he muttered.

"So then why did you cum? You know, I never thought you'd be this much of a whore," you scolded. The look on his face almost made you feel guilty. Still, this was turning you on so goddamn much.

"Something obviously needs to be done about you, Mettaton. And this isn't working." You told him, lifting his chin to he'd look at you. He looked like he was drooling slightly. This was gonna be the fun part.

"You're quite the slut, aren't you?"

"Y-yes," he stammered out.

"Yes what?" You grabbed him and violently jerked him around to face you.

"…I'm a slut," he mumbled.

You pushed him back and he sat on the bed, "I'm sorry, but I didn't hear you. Speak up, darling."

"I'm a slut. I'm your dirty, dirty, whore."

You pulled off your pants and your underwear. "You don't sound very confident about that."

"I'm your slut!" He exclaimed with finality.

You pushed him down and straddled his hips, "Then fuck me like one."

You didn't care that he was probably still sensitive or that you could drag it out longer if you liked. You wanted relief now. You held his dick and positioned him before bringing yourself harshly down. He whimpered aloud.

"Well, get on with it." You ignored your discomfort as you tried to adjust the feeling of him inside you. He wasn't exactly a modest size. "I'm not going to do all the work."

He seemed to internally struggle with the best way to handle the situation. He eventually sat up and leaned forward until you fell back with him under you. Your legs wrapped around his waist and he began to slowly work himself out of you.

"Holy hell, I'm not made of china. Be rough with me." You ordered.

He slammed his length back into you and you struggled not to moan aloud. You didn't want to give him the satisfaction yet.

He, meanwhile, was a complete mess, making no effort to hide anything he felt from you.

He continued to thrust into you as mercilessly as he could and you tried your best to seem impassive. Then he hit you just right and you saw stars.

"Do that again," you commanded him.

He was to occupied for his typical quip, and instead did as he was told. You moaned loudly, holy fuck this was good.

Again and again and again he slammed it and suddenly you came violently. Your walls tightened around his cock and you could feel him twitching inside you. You smiled mischievously and unhooked your legs, pulling off of him.

"What...?" He sounded betrayed.

"You didn't think I'd actually let you cum, did you? Please, I had to punish you somehow." You stood up and walked away to clean yourself up. You came back over to the bed where he was now sitting.

"You have to get going now, right? Isn't Alphys expecting you for something?"

He pouted at you, but you knew it was true. "May I have my arms back?"

You feigned incredulity, "So you can jerk yourself off? Never! Your audacity is surprising."

You helped him clean himself up and ushered him out the door. He'd be back. He'd be back time and time again until he earned what he needed.

A/N: This is pretty shit, sorry for the cringe. Anyways, that gets one of the planned one shots outta the way. Gnight, beautiful robotfuckers!
