He's beautiful. Kenny's body is a cosmos, mapping out the stars and planets in a way that makes his throat tight and heartbeat quicken.

Pale and bruised but still alive, he's gotten better at not dying. Lips like flowers, plush and pink and quite welcoming to Cartman's own.

Even though he's nothing but a visitor Kenny takes him in as well as the lead, fingers touching and stroking and constantly moving around, never stopping and never leaving Cartman's body.

Suddenly it's like electricity and Cartman see's the world through his lids, white and yellow and turquoise colors flash in unison. He finishes onto Kenny who laughs like he's in love.

He pressed his leg between Kenny's thighs, demanding and hurried and very much like himself. The blonde takes his lips and presses them to Cartman's neck, gasping. He takes Cartman between his legs and clenches with a resonating intensity they both feel rushing through their limbs.

He jerks awkwardly, the feeling of Kenny and his hands that are roaming around again are just too much. His body reacts faster than his mind and he grunts, pulling the other into him roughly. Kenny complies and his hand reaches down past Cartman's stomach to his own body, pulling and twisting and whispering the most wonderfully obscene things into Cartman's ear.

Then a tongue across the edge, dipping into the shell and…!

If what he'd felt earlier was good, the orgasm that gripped Cartman was borderline painful. His legs tensed and his body pulsated with a feeling like warm honey, spreading sweet and heavy from his toes to his tongue. The noises coming from the blonde under him confirmed Kenny had reached his limit as well.

His head now empty and pleasant, Cartman rolled over onto his back and Kenny leaned into his side and they lay like that for a while, absorbing the lingering heat. He glanced down and met the other's eyes, which were bright and lidded with a smile.
He supposed it was the shock of just sleeping with his childhood friend that caused him to stop breathing for a second and abandon any form of a thought process. Some invisible force gripped his heart just as strongly as Kenny's hand had been on his dick moments before.

Normally he would have been thinking properly and normally would never even imagine touching the smaller boy, but Cartman knew he'd lost all logical thoughts and emotions long ago the minute he entered Kenny's never ending universe, and their beings meld into one.
