Chapter Text
Sans didn’t understand why Mom had tied him down to the bed. He hadn’t been bad, right? Besides, he didn’t have an ass for her to spank as punishment, like he’d heard some of the normal kids mention before his latest birthday. He didn’t care, though. He didn’t care about anything. He couldn’t. He hadn’t been made to.
Then Azzy came in, and Sans felt his usual spark of belonging. That was his soulmate. That was his owner. He was Azzy’s. He was made for him.
Azzy came over next to him and caressed his cheek in that special way that, as it always did when Azzy touched him, made him feel alive and real. He gasped and leaned into the touch; he didn’t want it to go away.
“Heh. Hi, Sansy. I love you so much that we’re going to play a new game, okay? This one is called “fucking”. You’ve heard of it, right? Good. I thought Mom had told you. Well, yesterday was the last day that you and I were in stripes, so we can do this now. I’ve wanted to do it for a while, but I waited. Can I fuck you, Sans?” Asriel asked.
Sans eagerly nodded. He wanted Asriel to do this, and he’d wanted him to do it ever since he heard about it. He needed Asriel to fuck him. He didn’t quite know why, but he knew it had to happen. It was important.
Asriel leaned down and grinned at him, then planted a kiss on his teeth. Sparks flew just as fast as they had that first time. Then Asriel stepped back and asked, “Would you form something soft I can fuck, Sans? If you can’t I understand - I can still find a way to fuck you - but I’d really like to fuck something soft. I know Mom showed you all the pictures of the right parts, right? Good. Can you form one? I don’t care what you choose.”
With that freeing statement, Sans felt his blank ecto snap into place. He wiggled a bit with need, rubbing himself against the bed. Wetness was sliding down his body, but he didn’t care. The stimulation was too much - he opened his mouth in a silent scream.
Azzy giggled. “Heh, you can talk, Sans. I want to hear your voice, okay? I’m sure you’re going to make some wonderful noises for me.”
Sans swallowed, then, having been given permission, said, “yes, azzy.”
“Good boy,” Asriel said, filling his soul up with warmth, “Now, I don’t really know exactly how this goes, so it’ll probably hurt a bit, but I know you can take it. You’re mine, after all. Are you ready for it?”
“yes, azzy,” Sans responded instantly.
“Good. Here it goes!”
Sans couldn’t see behind him, but he sure felt it when Asriel’s dick forced its way into his canal. He screamed. It hurt! It hurt so, so much! Blank tears leaked into the blanket below him.
“Oh, Sans, I’m sorry, I’m sorry! I didn’t mean to… here, I’ll start moving. Mom said it would feel good after a bit, right? Let’s try to make that bit come as fast as we can.”
Then Asriel’s dick started thrusting inside him, and Sans whimpered. It didn’t feel good - it hurt! But, after a long, long time of quick, uneven thrusts, Sans started to feel something. His whimpers turned into moans.
His owner said, “It feels good now, right? I want it to feel good. I’m going to do this with you every day. Mom said we needed to make some kind of air? I’m sure we’ll figure that out later. Right now I just want to fuck you. You feel so much better than I thought you would, Sansy! You feel perfect! Heh, I guess that makes sense. Gaster made you for me, after all.”
The thrust continued, messy and sloppy with uncertainty. Sans didn’t care. It felt too good to finally be fucked by his owner. His tongue would have been lolling out if it wasn’t buried in the bed. He whimpered, “azzy, something- something’s coming! i feel so tight! what do i do?”
The thrust grew harder as Asriel groaned. “That’s an orgasm, remember? Mom told you about them. They feel good. Just let it happen. I want you to enjoy this.”
Sans didn’t get to respond before his body exploded with stars. He gasped as he felt his soul grow just a bit. Wait, what? He didn’t have long to think about it. Azzy’s sloppy thrusts stuttered and he buried his dick up Sans’ canal. It started spurting something warm into Sans. It felt right. It felt perfect. It felt warm as it spread through the lay lines he hadn’t known were cold. Temperature assailed him. Everything was so different! He gasped and came again, drawing a groan out of Azzy.
His owner pulled out of him sometime during his second orgasm, and Sans felt everything leave him… Everything but the feeling of temperature around him. What? He… He shouldn’t be able to feel that. Gaster had said so. Hmm… Sans didn’t want to tell him about this, though. He had a feeling Gaster would take it away. He had to tell Azzy. Azzy wouldn’t take it away.
Sans gulped, then said, “i feel cold without you, azzy. i thought i shouldn’t be able to feel that. can… can you touch me again? maybe? or give me a blanket?”
Azzy appeared in his vision, kneeling down next to him and smiling softly. “I’m glad you can feel that, Sansy. I want you to be able to feel everything. I hope you can, someday. I love you more than just a toy. I want you to be my other half.”
Sans blinked. If he’d been able to feel more he would have blushed. Azzy really wanted him? “are you sure?”
Asriel kissed him, lingering on his teeth for a long time. Then he adoringly stared at Sans and said, “I am, Sans. I’m more sure about that than I’ve ever been about anything in my life. Please, please say you want it, too. Please?”
With the truth ringing in his voice, Sans said, “I do.”
