Fem!Ren sucking Shinya off in one of those enclosed arcade machines that you sit inside

The moment that the door to the arcade machine had closed, a naughty idea had slipped through Rin's mind. Under normal circumstances, she might not have even thought twice about actually going through with it, but something about Shinya brought out the worst in her, only the naughtiest ideas, and she had the drive to go through with every single one of them, even if she knew deep down that she shouldn't give in to temptation. Her hand found his crotch, and in the time it took him to ask what she was doing she had already slipped down onto the floor of the machine and had moved between his legs

"What are you doing? I can't—" 'Focus on my game,' were going to be the next words out of his mouth, Rin guessed, but when her hand slipped up against his belt and she began to undo it, he paused all attempts at vocalising his protests. It seemed as if that protest had melted away entirely, with his hand soon moving to the back of her head as she pulled his appropriately-sized shaft out of his underwear and pressed a kiss against the tip, the shaft itself already partially hard from her prior teasing.

He turned into a panting mess long before she took his member inside her mouth, but it was only when she did that he began moaning, his head tipping back while his cock disappeared between her lips, inch-by-inch. Suddenly, his eyes snapped open. He looked around him. When his gaze dropped to her again, it was clear that he had just realised the significance of her sucking him off in a public place, but he was so overwhelmed by her mouthwork that he couldn't even stammer out the questions he wanted to ask.

Reaching up, he grabbed onto the lip of his cap, tugged it forward and pulled it down to cover his face, his cheeks deeply flushed as his member throbbed inside her mouth, his orgasm coming long before either of them had been expecting it to. Rin didn't chastise him for that, though, or even pull away from his cock. She wrapped her lips tightly around the head, sealed in the cum that followed and swallowed every ounce of it down as if it were a requirement for her to do so. She pulled up, settled her hand against his thigh and sat beside him again.

"You are going to play the game, aren't you?" she asked with a knowing smirk while he sat there, blushing.
