Doing the male swimsuit challenge

Futaba couldn't believe what was happening. Everything about it just felt unreal for her. For the entire day, Futaba would have to be completely topless at the waterpark and instead of a bikini bottom, she had to wear some swimming shorts that Ren bought her. It was supposed to help her blend in and look like a guy, but Futaba was pretty sure that people would still be able to tell that she was a girl!

Her breasts may not be as big as Makoto's or Ann's, but they weren't completely flat! People would still notice them! And even if they don't, there's still her body shape and face that are perfectly feminine!

Despite her worries that she would 100% get caught, she still agreed to the challenge. Not because she wanted to and not because of any peer pressure but because of what Ren promised...

The deal was that if she avoided being caught, she'd get to watch Ren and Makoto have sex. Makoto was definitely embarrassed by the idea, but by some miracle Ren convinced her to agree to it and Futaba knew that Makoto would honor her word... Of course, it wouldn't matter since she'd get caught... But there was still a prize if she got caught. She'd get to do anything she wanted to Makoto's bare butt for 5 minutes.

Even after Ren and Makoto started dating, Futaba couldn't help but continue to perv on that perfect butt and Ren definitely noticed. Still though, she was surprised that Makoto and Ren would come up with those ideas. They said its because they want to motivate her to do the male swimsuit challenge, in hopes that it'd help her get over her shyness... but was it really that bad?

She was definitely more shy than other people, but she gotten a lot better over the years... At least, she thought she did.

She tried not to think about it as she stepped out of the changing room, her breasts completely on display. According to the text that Futaba got, Ren was at the waterpark somewhere and would secretly be spying on her throughout the day to make sure she didn't cheat and to see if she got caught or not at any point.

She tried not to think about him hiding in the shadows, secretly spying on her breasts... Just like she tried not to think about the way her nipples were hardening as she walked past dozens of people. Any of them that could discover her secret and realize just how exposed she really was.
