     brushing your hair out of your face, giving a quick look at yourself in the mirror, you decided you were ready. Today you were going to tell mettaton, the love of your life, that you had figured out you were trans. This wouldn't be easy, but you were preparing for it for nearly over a month now, and now it was time. Slipping on your shoes, you walked out of your home, closing the door behind you. Mettaton said he would meet you outside.
     "Hello, darling? you wanted me to come over?" you heard a gentle voice say.
     "Mettaton! yes, I have something important to tell you," feeling too awkward to look him in the eyes, you took a seat on your front porch, Mettaton doing the same.
     Mettaton grabbed both of your hands, facing you with a concerned look. he was ready to know, you just hoped it wouldn't hurt him.
     "Mettaton, I'm trans. I hope this isn't too much, I hope I'm still enough for you, I just-" you were suddenly cut off by a hug.
     "[Y/N], you'll always be enough for me. Actually, I kind of went snooping through your phone and found out earlier," he said sheepishly. "I figured it was bothering you, so I asked Alphys to make you this," Mettaton pulled out a pink box, wrapped with a black bow.
     As you went to open it, Mettaton stopped you, and pulled you inside.
     "I just think it's more of an inside gift!" he said excitedly.
     As you opened the box, you felt your face flush. It was a robot penis? It looked like it had some connection points and would stick to your skin easily. It also had nice length and girth on it.
     "If you couldn't tell, it's a cock. Alphys built it so that when you wear it you can feel when it's touched! I was hoping you'd go down on me tonight?" he asked, grabbing your hand.
     You were so flattered, he brought you a prosthetic dick, and now he wanted you to fuck him with it?
     "Yes, I'd love to," you blushed, taking his hand and leading him to your bedroom.
     You watched as he laid himself on your bed, ass up, looking back at you needingly. You pulled down your pants, connecting the prosthetic to your body.  You felt a wave of feeling run through you as you stroked yourself. It really did work! Crawling onto the bed, you pulled his pants down. Looking at his bare metal ass made you feel a certain way, as you felt your newly attached cock stand itself up.
    Grabbing onto either side of Mettaton, you positioned yourself, slowly pushing yourself into his tight hole. For a robot, he was surprisingly able to stretch.
     "Gentle, dear!" Mettaton moaned out, feeling you deep inside him, his walls surrounding you.
     "I'll be as gentle as I can, love." you cooed into his ear, before slowly starting to rock your hips.
     Keeping a slow pace, you pushed yourself farther and farther into him, hearing Mettaton's moans echo throughout the room, your own echoing to match.
     "Please, faster!" Mettaton almost shouted, gripping onto your sheets in desperation.
     You rammed your dick faster into your lover, pushing as hard as you could, until you felt pressure building up in your body. You didn't want to release this soon, but it was your first experience, and by the sounds Mettaton was making it sounded like he was close too.
     "Love, can I cum inside you?" you practically begged, feeling yourself get closer and closer with each thrust.
     "Please!" Mettaton stuttered out, too overcome with pleasure to even speak properly.
     You sped up as fast as you could, pounding as hard as possible, until you felt your entire body go numb, releasing into the frail robot beneath you. With a quivery moan from Mettaton, you watched as he also released onto your sheets. You didn't even know robots could cum. You pulled yourself out of your lover, taking off your prosthetic.
     Exhausted, you laid down next to mettaton, facing him as he was you. staring longingly into each other's eyes, you felt content. The love of your life had not only accepted you as you are, he got you a gift, and he wanted you inside of him. The least you could do was give him aftercare, you just needed a moment of rest.
     "Oh yes~ that was magical darling, I'd love to ride you next time," he spoke with a smirk on his face. "You were an amazing dominant partner," Mettaton said, stroking the side of your face as you smiled.
     "I'm glad. You're not hurt are you? could I get you anything?" You said with slight concern.
     "I'm fine, I just need some sleep, but I expect you to spend the rest of tomorrow with me. We could have a lazy Sunday!!" He beamed.
     "Of course, anything for you love," you whispered, wrapping your arms around him as you both drifted off.
