Kabuto always seemed to fall asleep at the most inopportune times. The medic had a knack for being unconscious right when Orochimaru most required his assistance, and this was one of those times. "K-Kabuto!" The snake yelled for the eighth time, silently cursing himself for stammering. Beneath the sheet (a thick blanket laid off to the side, as Orochimaru would be overheated one minute and freezing cold the next), a pale hand gripped at his crotch in an attempt to stave off the accident that was beginning to seem inevitable. "KABUTO!" When there was no forthcoming answer, the snake swore quietly and struggled to lift himself out of bed. The instant he removed his hand from between his legs, a stream of urine escaped him, wetting his underwear and making his chalky face turn red. Orochimaru bit the inside of his cheek and gripped himself tightly, terrified that he would lose control and be found in a puddle of his own creation, cementing his status as an invalid in Kabuto's eyes. He could already hear the boys condescending tone. "I'm sorry, Lord Orochimaru, I didn't realize you had to go so badly. Forgive me." Then he would adjust his glasses, never once bothering to hide the smirk on his face, and help his master to the bathroom, where he would insist on bathing him because "you're clearly very ill".
Several agonizing minutes passed, and Orochimaru now had his legs pressed tightly together, his entire body trembling with the effort of holding back a flood. "KABUTO! PLEASE!" Yelling only made the pressure worse, and not even a minute later, the snake felt a deluge of liquid escape him. Hot shame engulfed his stolen body, and he closed his eyes to fight back the tears gathering there. He was one of the three great sannin; he'd sooner jump off a cliff than cry over something as juvenile as...as pissing himself in bed. The full force of what he'd just done hit Orochimaru in the face. Here he was, immortal, nearly all-powerful, a genius, an adult, sitting in a pee-soaked bed with clothes that reeked of urine and no way to move or clean himself. Utterly humiliated, Orochimaru fell back onto the pillows and waited for his useless assistant to come in and see what he'd done.
A/N: I'm not sure if you'll thank me or hate me for this, but I went ahead and wrote this Orochimaru bedwetting one-shot. We can call it Omochimaru. *ba-dum-tss*
