(Few weeks later)

"H-Hngh!"

Lust gripped the bedsheets behind him, slamming his eye-sockets shut to keep the tears from spilling over.

Papyrus thrusted his cock deep into the smaller skeleton, making him buck and arch his back.

"H-Hah!" He trembled fearfully under Papyrus. "Pl-Please, master, sl-slow down.." Papyrus only smiled in response and continued his fast rhythm.

Papyrus suddenly paused his thrusting, looking at Lust with a predatory smile. Lust shook under his gaze. The Papyrus hummed thoughtfully, a sudden idea coming to him.

"Hmm.. I've never played with your soul before.." Lust froze, staring up at the taller skeleton with wide eyelights. He instinctively covered his sternum with a hand, where his soul lay underneath.

"N-No, please m-master.." Lust trembled, his ears flattening down fearfully.

Papyrus gently removed Lust's hand from his sternum. Then, his own hand lighting with blue magic, he pulled the smaller skeleton's soul out of his ribcage.

Lust swallowed, staring at the upside-down heart encased in blue magic in front of him. He looked up with scared, desperate eyes. "N-No.. please.."

A monster was only supposed to show their soul to the ones they truly trusted. That was usually limited only to close friends, family, or lovers.

However, Papyrus didn't care. The blue magic extinguished, leaving heart-shaped object to hover peacefully in front of him. Papyrus stared hungrily at it. It was glowing an alluring lavender, pulsing softly with each of Lust's soulbeats. Lust swallowed, shivering at Papyrus's expression.

Papyrus brought a finger up to hover in front of the floating vessel, pausing. Then he ran his finger lightly over the surface.

Lust's face flushed light purple.

"Hnngh!" He gasped as an unexpected wave of pleasure washed over him. Papyrus watched Lust, smiling in amusement. Then he started to play a little more rough.

Papyrus took the soul into his hand, squeezing it in his fist. "G-Gah..!" Pain rocketed up Lust's spine, making his tears spill over. He huffed, his breathing erratic. A sticky liquid began seeping from the soul through Papyrus's fingers.

This was a whole different kind of pain, one that you felt at the very core of your being. Lust was suddenly even more afraid.

Papyrus brought Lust's soul to his mouth, licking it teasingly. Lust spasmed under Papyrus, a desperate noise escaping him. His eyes rolled up as he gasped for air, trembling.

"H-hah..! Pl-Please master.. Aa-aaH! I-I can't.."

Papyrus chuckled as he watched Lust become a trembling mess underneath him. He should've done this ages ago; it was so much more entertaining!

Papyrus brought Lust's soul to his mouth again, this time putting the entire thing inside.

"Nngh..! Hah.. hah.." Lust breathed shakily. His vision was blurring from his tears and he couldn't concentrate on anything. The pleasure and the pain were both so intense that it was all he could do to hold himself together.

Lust screamed as Papyrus pulled his soul out of his mouth. Pausing, Papyrus let the soul hover above his outstretched palm. He could see a faint line from where his teeth had probably scratched it when he had pulled it out.

"Really Kitty, there's no need to scream like that. It's only a little scra.."

Papyrus stared down, shocked, at Lust. The fragile skeleton was still shaking and crying, but now a line of blood dripped out the side of his mouth, staining the bedsheets red.

"Pl-Please m-master.. I o-only h-h-have 1 HP.." His heart-shaped pupils flickered weakly. He was so scared that he was going to die and he could barely speak past the pain.
