Inspired by trinnerti's "The Day Sakura Helped Kakashi." If you haven't, it's worth checking out (look on the kakasaku livejournal community). Reviews are always welcome!

The problem all started at the fifth annual Icha Icha Festival. What had started out as a festival honoring the legacy of Jiraiya quickly devolved into the debauched celebration (forcing a name-change from "The Legendary Toad Sage Festival" to its current one). Nowadays, it was a festival aimed at boosting Konoha's falling birth rates with sex-themed festival games, and it was at one of these games that our story begins.
The prize had not been too spectacular. Just advance tickets to the next Icha Icha movie and a copy of a valuable Icha Icha book Kakashi already owned, but it did nothing to dampen Kakashi's competitive streak at the "Bobbing for Sex Toys" game. Probably because Gai was taking part and issuing a challenge for bragging rights with his partner Lee.
The game was simple. In a large basin of water, there were various items of sexual paraphernalia with points attached, ranging from nipple-clamps for five points to a large plastic dildo valued at 200 points. With a minute on the clock, competitors were to grab as many items as they could with their mouths with the largest point total winning the prize. Sakura had the misfortune of being partnered with Kakashi for his little charade.
With more pressure than needed, the hand firmly gripping her head forced her face under once more.
"Twenty seconds left, Sakura. Go for the vibrator!" Kakashi encouraged, seemingly oblivious to the pink-haired medic's inability to breathe under his hand. However, in spite of this, Sakura dutifully obliged and aimed in the vague direction of the fake phallus. Feeling it under her lips, she opened her mouth and pulled her head back, only for the lack of air to catch up to her, dropping it with a vicious cough as water entered the wrong pipe.
She could feel Kakashi's dismay as the fingers gripping her head tensed a bit.
"Come on, Sakura! I know your gag reflex is better than that!" he shouted.
Almost instantly, Sakura pulled away from the pool, whipping her head around in mortification. Even Kakashi seemed to sense the mistake that just left his lips as the fairgrounds suddenly grew quiet. The music had stopped; Tsunade was now standing over the shattered remains of her vintage sake bottle; Gai was in the process of halting Lee's attempts to drown himself in their team's basin; Genma dropped his senbon straight into his foot. The announcer, who had a vague notion of who the villagers were, didn't know quite what to make of this, microphone screeching as it hovered halfway between his lips and his chest.
Near the basin, a neon purple dildo fell from Sakura's lips, bouncing harmlessly on the concrete near Kakashi's feet as the buzzer rang above their heads. With a total of 356 points, Kakashi and Sakura had won the challenge, but it was an afterthought compared to the fact that the entire adult population of Konoha now knew she had been screwing her former teacher.
Meeting Tsunade's furious gaze across the crowd, Sakura vowed to herself that this would be the last time she ever did her boyfriend a favor.
