Ren makes her masturbate & strip on the train

"Ren, I-"

"You promised, Makoto."

He slowly turned the vibrator up, causing Makoto to let out another moan into her hand. The first three months of their relationship was normal. It was what she expected from the research she's done online... But eventually, things got a lot more perverted. Most of the time, she was fine with it. They were a couple and couple did lewd things after all.

It may have been embarrassing to be groped or spanked by her boyfriend, but because it was him doing it...and because it felt a bit good, she didn't mind that much. Things slowly started going further though. Ren convincing her to take off and hand over her panties in public. Ren taking her bikini bottom off while their in the jacuzzi. Ren convincing her to give him a handjob under a blanket at the beach.

Despite things going further and further, she was fine with it. Not just because they were dating and because part of her was turned on... but also because he had a good reason for it. He wanted her to get out of her comfort zone. In the past, people had called her a robot and the more she thought about it, the more she could understand why. It took meeting the Phantom Thieves to understand that life wasn't just about studying and trying to get a good job.

Ren took it upon himself to try and help her get out of her comfort zone. To embrace the other parts of life that most other girls engage in. Including embracing her sexual side... Part of her knew that Ren was being perverted and was asking her to do all these things for his own satisfaction, but she also believed that he was doing it to help her. She was right... but at the same time was underestimating just how perverted Ren was. His own lust was the number 1 reason for the things he was making her do.

One of those things included using a vibrator on the train. Originally, Ren was supposed to finger her but after the two talked about it, they decided on a vibrator instead. It felt less risky to Makoto. People would be less likely to notice a vibrator inside her compared to Ren's fingers.

Of course, she completely ignored the fact that by the end of the train ride, everyone around them would see her naked. Though she really didn't want to think about that. She still couldn't wrap her head around the next part of the task.

As the train stopped and new people got on the train, Ren and Makoto stood up, letting others take their seat. Not out of the kindness of their hearts, but because of the next part of the task. Makoto already had the vibrator inside her and was close... now she just had to lift her skirt and flash her pussy and the vibrator to someone and cum infront of them...
