Both Carl and Chase were nude in the former's bedroom. The two ten year olds were bothered by the heat even with the AC in the mansion, so they stripped down to nothing, knowing Carl's parents' wouldn't check on them. Both boys were used to seeing each other naked. Both boys were also avid porn watchers, and sometimes got hard seeing each other in the nude, though they usually took it in good fun. Today though, Carl was feeling butterflies in his stomach as he watched a nude Chase splayed on the bed, playing on the console. His plump ass looked inviting, the little pink anus twitching. So, mustering his strength, he spit on his index and middle fingers and touched Chase's anus. Though it tightened on contact, the two fingers slip past the ring. "Dude, what the hell!?" Chase said. Carl shrugged, and kept fingering his best friend. The pressure on the prostate and anal glands made Chase moan, and though he tried to return to the game he could no longer get in the zone and lost. He angled his butt to the left, half-assing at getting away from Carl's fingers. "Dude, stoooop" Chase moaned, the fingers withrawn, his pink anus gaping and wet from the saliva. "Why, you're enjoying it you little slut" Carl said. Carl tried to insert his fingers again, but Chase wagged his ass, escaping. The two of them laughed. "Just let me in!" Carl said. "Nope" Chase said, laughing. Eventually though the otter got tired, and Carl lined his fingers. Chase said nothing, bracing for impact... ...and for the first orgasm of his life.
