Part 13 of 20: Well, That's One Way To Show Them What's Yours

Mettaton stared wide at Lust's purple member, flushing bright red. His eye twitched as he turned away, flustered.
"I-I'm a TV star! I don't really get bothered by many things." Nervous sweat broke out across his forehead.

Papyrus smiled in response, then reached down to grab the smaller skeleton's length. Lust's eye-sockets widened, his blush darkening to a deeper purple. Then Papyrus began to stroke it up and down, applying a steady pressure.

Lust gasped, and made a sound between a moan and a stuttered breath. He tried to cover his mouth, but Papyrus reached up and pulled Lust's hands down.

"Hngh! A-ahh..!" Lust cried out as Papyrus began to pump his member more forcefully.

Mettaton could only watch wide-eyed, his whole face heating up. He couldn't look away or speak. He was so shocked that he could only stare, frozen, at the scene in front of him.

"M-Master pl-please! St-Stop!" Lust cried, his erratic breathing making him stumble over his words. Papyrus only smiled down at him.

Suddenly, he squeezed Lust's member hard. Lust gasped, tears pricking at his eye-sockets. "H-Haah!"

Papyrus leaned down to whisper in Lust's ear. "Won't you cum for me, little kitten? It's always so hard to get you to do that." Lust's eye-sockets twitched, his breathing shaky.

Lust was very good at controlling his own physical reactions during sex, as he had had much sexual experience from his home universe. Because of that, he could stop himself from cumming if he wished.

Unfortunately, Papyrus was squeezing his dick so hard that his mind was beginning to black out.

"You're hurting him!" Mettaton cried, snapping out of his daze. "Stop it!"

Papyrus looked up, smiling sadistically at Mettaton. "Do you not find him attractive when he's moaning and squirming like this?"

Mettaton looked at Papyrus in disbelief as Lust's moans and whimpers filled the room. He couldn't deny that watching the attractive skeleton being manhandled this way was exciting him. But it was also sickening seeing how much pain the small being was in.

"I-I don't know! Just stop!" Mettaton's face flushed red. Mettaton was surprised at himself. He usually didn't care whether others were getting hurt, as that was a common occurrence around their universe. But he felt protective of the small, lavender-eyed skeleton.

Papyrus only laughed. "It seems you can't accept the truth yourself."

He squeezed harder, making Lust buck and arch his back, tears flowing down his face. Mettaton, swallowed, realising upholding his pride was doing no good if it meant Lust had to suffer. "Fine! Yes, I think he's attractive! Just stop hurting him!" Papyrus smiled, looking back down at Lust.

"Nngh.. hhh-haAAH!" Lust cried as Papyrus squeezed his dick so hard, the pain shot up his entire body. He felt something trickle out of the tip. Papyrus released him, making Lust slump against Papyrus's ribcage.

Lust trembled against Papyrus, purple cum dripping out of his glowing penis. White spots danced in front of his eye-sockets. He felt so humiliated, but he couldn't focus on that past the jarring pain coming from his sensitive length.

Mettaton stared at Lust. His cheeks were flaming red and his breath slightly laboured from watching Lust's torture. He couldn't believe what had just happened. A part of him was so horrified that he wanted to run out of the house, far away from here.

But another, more shameful, part, felt a coursing desire to make Lust do those noises again. Hear him moaning, crying, screaming, his beautiful voice filling the room with its melodious song. Him squirming underneath him, begging, looking up at him with those deep violet eyes..

Mettaton shook the thoughts out of his head, his face burning shamefully. Here he was, contemplating doing the same horrific thing as Papyrus had.

"I-I need to l-leave. I can't.. sh-shouldn't.. stay h-here.." He stumbled to his feet, making a beeline out of the house.

Papyrus smiled, stroking Lust comfortingly as the small skeleton trembled weakly in his lap. That rust bucket wouldn't be back anytime soon.
