Fuyuhiko was surprised at first when he saw Peko training in her underwear, but that surprise soon turned into arousal as when she sliced down on a watermelon, her breasts, confined only by a thin black bra, bounced wildly. He could feel his dick stiffen immediately in his pants as he hid behind a tree.

Now, could you blame him? Despite the impression he gave off, he was still a teenager. He wanted to watch her, watch her body move and jiggle. She even turned around and gave him a great view of her ass moving around as well at one point.

He'd always found Peko attractive, but their relationship made it very difficult for him to really do anything about it, other than jerk off to his own imagination at night. But that currently left him wanting to take his dick out right now and do it while watching the swordswoman and her body. He knew he shouldn't; if she saw there'd be no way to explain it, but…

He couldn't resist. He unzipped his pants, and yanked his dick out from underneath his pants and boxers, and started to masturbate. He watched her chest move up and down with every movement she made, and got so into it that he leaned his head back and groaned, closing his eyes as he imagined his hands on those soft mounds. Yet, when he opened them again, she was gone. He felt a chill go down his spine that he couldn't explain.

"Young Master?"

Fuyuhiko jumped and turned around, falling backwards onto the sand as he heard Peko's voice from behind him. As soon as she saw his dick, still out in the open, she actually blushed a little.

"P-Peko! Th-this isn't what it looks like!" He said as he frantically tried to stuff his dick back into his pants.

"Young Master? Would you like me to…take care of that for you?" She asked, and immediately Fuyuhiko froze, his mind grinding to a complete halt for a few moments.

"U-umm…"

"If you are uncomfortable, it is my job to make you feel better, so…may I?" She asked, seemingly unable to tear her eyes away from it. Fuyuhiko stopped thinking, and let his second head take over.

"Y-yes." He squeaked. Peko nodded, got on her hands and knees, leaned down, and as Fuyuhiko laid there, she opened her mouth and gently put his head inside. As soon as her lips touched his skin, he groaned loudly, his body shaking. Peko smiled as she took in even more, sliding her tongue against the boy's skin. Her warm breath and hot tongue made the boy squirm and shake with pleasure. He didn't know it could feel this good!

She pushed him deeper and deeper inside her mouth, not gagging even a single time, having been rigorously trained against that, though admittedly for other reasons. Soon, his entire length was inside, and she wrapped her tongue around it, touching every spot she could, feeling it throb.

"F-fuck!" Fuyuhiko groaned. "That feels so…gooood…" He said, and Peko smiled more. She was happy to make him feel this way. She lifted herself up and then moved back down, never stopping at flicking her tongue over every inch of skin. Fuyuhiko could feel the familiar pressure building inside, and he knew he wouldn't be able to hold it back. It almost seemed like Peko was able to tell, as she took his entire dick in her mouth as he came, spewing his semen down her throat. Even then, she didn't gag, swallowing up every single drop, feeling it slide warmly down her throat. He shook as it flowed out, until he was completely empty, and she pulled away, wiping her mouth.

"Holy shit…" He said. That was one of the best things he'd ever experienced.

"Young Master?" She suddenly said.

"Y-yeah?"

"If you want…I can make you feel even better." She said, looking away with a slight blush. Fuyuhiko gulped.

"Yes please…"

The two went back to his cabin, where the spent the rest of the day with Peko relieving all the stress Fuyuhiko had been carrying through the power of sex.
