First, she let's him explore her body!

Denki led Akemi and Momo to the nearest unisex restroom, and locked the door behind them. "...okay, normally I'd find this a bit creepy, but I honestly don't care right now," Akemi noted, shifting from foot to foot.

Denki smiled, turning to Akemi. "Bikini top off," he ordered her confidently.

She blinked, but grinned, and moved her hands, up her sides, and to the knots behind her back. "Okay, whatever you want!" she replied, undoing the knots and shrugging the bikini down her arms. Her breasts jiggled slightly into view, and she placed her hands over them, with a faint smile. She knew full well that he would just order her to move them, and she would, but that was the point.

"Hands behind your back and stand still," he chuckled, and she nodded, dropping her hands and clasping them behind her back, jutting out her chest. He then approached her, and lightly cupped her breasts, making her moan and press her chest into his hands.

"Unh... so... how are you making me do this, and why am I enjoying it so much?" Akemi moaned, more curious than anything. She was having a better time than she had ever had before.

"...you can make her forget later, if needed, right?" Denki asked Momo, continuing to fondle Akemi's boobs, lightly tracing her nipples with his fingers.

Momo nodded. "Of course, Master..." she assured him. "You shouldn't have any problems telling her, even if this is a catch and release situation..."

Denki nodded, lightly pinching Akemi's nipples, and considered what to tell her. As Akemi crooned, he then reached down, pulling her bikini bottom strings to undo them, and let the garment drop. She squirmed slightly, but remained in the position he had ordered.

(Side note, should Denki go through with the catch and release thing with Akemi, or should he keep her? Given she's just a random OC inserted, I'll let you all vote on that. Some people seem like they'd rather keep her around as a regular fuck buddy.)
