❤️Love you guys!❤️

"THANK YOU ALLLLLLLLL FOR TUNING IN! SEE YOU ALL NEXT TIME!!" Mettaton sung into his microphone, fog spreading into the stage as the curtains fell. Loud clapping could be heard throughout the whole theatre.

"Ahh..I'm such a star! They love me.." He mumbled to himself, walking to his dressing room to fix himself up.

"There he is! Okay..just go and say hi.." You mumble to yourself, surprised you even got past the security.

You moved from behind the rack full of dresses and dashed to his dressing room, knocking without a second thought.

"Whoo is it?!" Yelled Mettaton as he opened his dressing room door.

You stared at him, eye to eye, his expression changing from aggravated to soft and sweet." Oh hello darling! Are you a fan?" He asked, seeing you could only stare.

"I'm..um.! Mettaton.." Was all you got out. You finally snapped out of your daze when you heard yelling to your right.

"Uh oh! Looks like someone else tried to sneak in.! Come on in!" He said quickly, pulling you into his room.

He locked the door like he usually did and sat in his make up stool." I don't have much time..what was it that you have to say or do?" He asked, staring at himself in the mirror.

"W-well I had a few questions and wanted to know if you would sign my wrist!" You said with a smile, rolling up your sleeve to show Mettaton your wrist.

"I was going to get it tattooed." You added, seeing mettaton's eyes get glossy.

" oh you are the sweetest!!" He quickly came over but tripped over a misplaced scarf.

"Oh goodness!"

Boom!

"OooOOoHHhh.." Mettaton groaned on top of you, his arms on your chest and your hands on his waist.

Your face darkened but before you could apologize, Mettaton gave you a smirk and said in a whisper,"Well helllloo there darling.~"

You sucked in a breath as you felt your member rise in your pants, hoping Mettaton couldn't feel it since robots can't feel anywhere except for their hands...right?

Wrong.

"I think someone else came to say hi too..~" Mettaton chuckled, pushing himself up so he was sitting on your waist.

"Well well your such a naughty boy..you need to be taught a lesson..~" sung Mettaton in almost a lustful tone.

Your dreams were coming true and it was all from him slipping. You didn't say a word, only nodding and getting a giggle from him in response.

He moved back and undid your belt and button, pulling your pants off only to leave you in your boxers.

Mettaton took a finger and grabbed the hem of the boxers, pulling down ever so lightly before your dick sprung out.

You bit your lip, not knowing what he would say.

"M-my..my goodness.." He said shocked.

"W-what is it..?" You asked nervously, watching his hand snake around your dick and give it slow strokes.

"I've never seen anyone this big before.." He purred, his metallic tongue slipping from his mouth and slowly running up your shaft.

"Ngghh!" You moan, his tongue being ice cold.

"Such a surprise huh?" He chuckled, pushing your dick into his mouth, bobing his head up and down.

His mouth and tongue did most of the work, his hands giving you a few pumps here and there.

"Ah! M-Mettaton.." You moan, holding yourself back from tackling him and taking him there.

He pulled off of your dick with a popping sound and wiped some saliva that went down his face, his lustful eyes speaking for him when you both locked eyes.

"Now I'm not like no regular female.." He started, touching the heart on his belt that looked very glossy. When he pulled his fingers away the goo followed with his fingers.

"I mean I have a hole of course but this makes it easier~" he sung, wiping the goo into your dick, pumping his hand a few times to get it all over.

A smirk grew on your face as you sat up, tackling Mettaton. You couldn't hold back now. You held him down and watched him stare up at you with wide eyes.

"Well darling I didn't know you were a dominant one~" he chuckled, watching you hover over his hole.

"Well hurry now..we don't have much time.." Mettaton sighed, watching you position yourself.

"I'll make this fast." You growled, pushing yourself into him quickly.

"OoOohhHh.!" He moaned, his legs wrapping around your waist.

Mettaton's insides felt like any other woman's womanhood. Warm, soft, and gooey.

A sudden knock upon Mettaton's door rang through our ears.

"5 minutes Mettaton.!" Yelled a girl, her footsteps trailing off.

"Ohhhh tha-oh! Right Th-there!" He moaned, his face showing pure ecstasy with every thrust.

"I-I'm going to cum!" You groan, watching Mettaton nod in response.

"S-same d-darling! Hurry! I'm so close!" He moaned and that sped you up.

After a few more pumps you both cummed together.

Panting and covered in sweat you pulled yourself from him and watched your seed spill out of him.

"S-so much..." He mumbled, slowly sitting up."I think I almost blew a fuse.." He chuckles nervously.

You chuckle lowly and stood up, fixing yourself."I think I should be going before they start asking for you.." You said with a smirk, grabbing the pen Mettaton dropped when he tripped.

"About that signature.." You asked, handing him the pen.

He nodded and signed your wrist, his handwriting still so steady and beautiful.

" th-there you go darling~" he purred, then placing a kiss half a inch above the signature, his black lipstick staining your wrist.

You smiled and helped him up and ready for his next show.

"I'll tell security to not touch you." He chirped at you before walking out with you.

You nodded and hugged him, kissing him on the cheek before walking off.

After Mettaton finished his show and walked back to the dressing room, he saw on his mirror, in beautiful handwriting, your number with your name and a lipstick mark.

"Oh my darling!~" he said happily, taking a picture of the message.
