"Hahahahahaha!" Hiyoko laughed maniacally as she waved around Hajime's trunks in victory. Meanwhile Hajime, who was now naked, stayed in the pool, at the edge, trying to coax the girl into giving them back after he had lost them from a poor dive. He knew he should've tried to find some tighter ones.

"Seriously, give it back, this isn't funny." He said.

"Oh I think it's quite hilarious!" She said, and to demonstrate her point, she lowered them down just within Hajime's grasp, only to pull them back as he lunged for them. She cackled as she played with him like this several times.

"Hiyoko, just give me back the trunks." He said, wanting to punt the little brat as far as he could.

"You'll have to come get them~" Hiyoko teased. Of course, she was only going to play with him for a while before she gave them back. But then, she saw him sigh, and swim over to the ladder, which only made her smile widen. Usually she didn't really care to see those weird small things that guys had, but she did like seeing them get embarrassed over having them so exposed. "Wow, didn't think you'd actually be man enough to come out of the water!" She expected to see him holding his hands over his small dick as he got out, and watched, waiting. But then, to her shock and horror, he stepped out, without bothering to cover himself at all. And on top of that…he was…BIG. Bigger than any others she had ever seen before. The way it swung from side to side as he raised himself out of the water, and how the water dripped down the shaft, catching the light as it hung on his head for a moment before falling off. It made Hiyoko's body feel…hot. She felt…tingly, and was unable to tear her eyes away from it.

"Can I have them back now?" He asked, his cheeks a light red. Hiyoko found herself struggling to speak for a while, but when she recovered her voice, she tried to save face.

"Wh-what, are you an e-exhibitionist or something? Wh-what a pervert, showing a girl your…your…b-big…AH!" Hiyoko had to stop herself from saying more, and Hajime raised an eyebrow at her. She noticed it twitch, and she squeaked.

"Are you okay…?" He asked.

"I'm fuck—I mean fine! I just feel a bit cock—I MEAN COLD…no, wait I meant hot! Fuck!" She sputtered, still unable to look away from his dick as it twitched.

"Hiyoko? Are you…horny?" He asked with a smirk.

"N-no! Eww! P-pervert!" She shrieked, blushing deeply as she finally looked away. Suddenly, she felt hands on her shoulders and jumped at the touch. She looked up to find Hajime staring down at her smiling.

"You've been staring at it." He said.

"Th-that's—!"

"If you want…I can show you what you can do with it." He said calmly. Hiyoko glanced down at it, watching as it started to stiffen, the veins popping out against the skin, then looked back up at him.

"O-okay."

The rest of that day was full of Hiyoko learning just how amazing dicks could really be, and all the wonderful things you could do with them.
