"BABE, WAKE UP... SOMETHING'S WRONG..." Papryus was shaking you as your eyes slowly opened, revealing the skeleton looking directly into your eyes. He was sweating. You knew something was wrong since he didn't have his cheerful smile like he usually did. "What happened?" You asked, pressing your hand on Papyrus' sweaty cheekbone.

"UHH, SOMETHING FEELS WEIRD..." Papyrus placed his hand on his pelvis. An orange glow was emitting from it. "...DOWN THERE."

You blushed heavily and something came to mind. Sans had told you about it, but he probably didn't tell Papyrus. "Y-you're uhh, probably in heat..." You whispered. "Sans told me about it."

"I WAS GOING TO ASK YOU WHAT IT WAS, BUT I HAVE TO DO SOMETHING ABOUT THIS..." Papyrus pulled his pants down, revealing a long, orange member. It felt like he already knew what to do. The skeleton stripped you of your clothes. He leaned down to nibble on your collarbone, slowly navigating his hand down to your breasts. He fondled one, placing two fingers on it and pressing your nipple in between them. He wiggled his fingers around. You yelped quietly.

Papyrus let go of your nipple and dragged his tongue down to your crotch, licking the soft mound. You covered your mouth, trying to keep quiet. Papyrus yanked your hand off of your mouth. "COME ON, BABE, I LOVE YOUR CUTE FACE." You decided to bite your lip.

Papyrus started to press two fingers against your entrance, rubbing it gently before embedding his fingers into your walls. He was feeling around, wiggling his fingers inside of you. You were getting so wet. His fingers started to pump in and out of you, leaving you with your head rolling back and you letting out muffled moans.

You finally stopped biting your lip, realizing that it's no use at this point. Everything felt so good, and Papyrus already knew you were ready. He slipped his fingers out. You saw your juices now coated his fingers. He grabbed your hips and pressed his cock against your entrance. Papyrus gave you a dominant stare before thrusting into you, fucking you at a gruelingly fast pace.

Papyrus was already moaning. You felt his heated cock throbbing inside of you. You were taking in so much pleasure that it seemed unbearable. Every inch of his cock was buried into you, thrusting in and out until you couldn't take it anymore. Tears of pure ecstasy were pouring down your cheeks, and you couldn't hold it back. It was already happening.

You squealed as your walls clenched around his cock. You were getting so tight that Papyrus' thrusts were slowing down, finally letting him halt with his cock deep inside of you, covering every square inch of your walls with his seed.

You started panting as his cock dissipated. His heat was finally done, and you cuddled next to Papyrus before you both fell asleep.
