Monster Ultra but it's Karlnapity

Chapter 5: Almost over

"Orrrr I could send Dream some pictures of you, Monster can up your ass with you drooling and crying because of it." Sapnap paused, biting Karl's nipple and growling at the mew he received in return. "I'd have to, he wouldn't believe me if I told him you took a whole Monster can up that tight little ass."

Karl whined softly "Daddy, please."

So Sapnap did.

He boosted the vibrator all the way up and watched as the blonde's hips thrusted up violently, the rope leaving dark red/purple marks on his skin and the head of his spent cock coloured the same way.

Quackity handed out Sapnap's phone, which Sapnap took without hesitation. Opening his camera and snapping some pictures, watching the way Karl's cum pooled in his stomach and his eyes were wide and leaking tears.

He didn't send them, and he probably wouldn't, but just the idea was enough to make Karl drop off of the edge for the third time, the dry orgasm was painful, and Sapnap and Quackity almost pitied him.

Almost.

Quackity didn't turn down the vibrator nor Sapnap either, keeping it at full power and the brunette picked back up the harsh thrusting with the can.

It hit his prostate every fucking time and Karl was back to screaming. "Too much! No, Quackity! Sap! I can't! No more!" The two only laughed.

"If you don't colour out, I'm not taking it out. One more time, yeah? Think you can handle one more? Four is my lucky number, baby."

Karl whined and nodded, his head dropping to the side as his body went limp, drool spilling at a rapid pace from his mouth and his eyes rolling back and if it weren't for the never-relenting gurgling of simultaneously 'more' and 'stop' he probably would have thought that Karl had passed out.

Quackity moved one hand, the one that wasn't rough-fucking the older boy with a Monster can, and brought it over to the dark head of his cock. He pressed his thumb to the head and he could still feel the vibrations, Karl letting out a high pitched whine as his dick twitched harshly, painful sounding moans tore from his throat and his stomach clenched tight.

And that was four.

Quackity nodded, as Sapnap quickly turned off the small black device, unfastening it and throwing it in the box on the floor. He moved to pull out the can second, relishing in the devastated whine that dropped from Karl's lips.

"No. Empty."

Sapnap smiled softly, rubbing at Karl's stomach as Quackity began untying the ropes that bound him. The ones on his legs left harsh burns that both of them knew would hurt and as he untied his wrists he saw that they were in a similar state.

He put the can on the bedside table before he stood up.

"I'm gonna get you some cream for the rope burns and a glass of water. Do you want anything else?"

Karl thought for a moment before his tired eyes fell back to Sapnap. "Cuddles?"

The brunette laughed softly from the doorway, Quackity lying next to Karl, wrapping his arms around him "Yeah okay, cuddles are good. Be back."

And as Karl watched Sapnap walk to the kitchen, his eyes trailing over to Quackity as he tried to let his hazy brain clear, thinking about it. Sapnap and Quackity just fucked him with a Monster can. And he liked it.

What the fuck?
