Offers her sex

Minori wakes up with some weight on her. She realizes it's her boyfriend naked and sucking on her nipples. Once she comes out of a daze... "AAAHHH!!! What do you think you're doing sweetie?" She screams scooting back to the wall behind her. "Also why are you naked?" She looks at her crotch. "WAHH!!! Why am I also naked!?!?!?!? Pretty sure this is illegal!"

"Shhh, don't worry baby, no one here cares enough if you're naked to do anything." He says trying to get her to calm down. "I thought you'd be used to being naked anyway though, being a shinobi and all. While he's right on the fact that she's a shinobi, and Minori knew he knew this too since she told him, the real difference here is that it's usually with some shinobi magic that makes nudity not matter much so no normal people can see them. "Besides, who doesn't wanna see such a beautiful figure like yours in their birthday suit? Literally in this case."

"Minori doesn't quite understand what you're getting at."

"Uh, how do I put this? You know what sex is right? I was planning on making that your real birthday present."

"Well you could've just said so earlier! Minori would love that from you. Not sure why you took us to a water park first though." She flirts with by playing with his face. He kisses her back on the lips and nipples. Minori blushes.

"I thought it'd be more fun and hotter to do it out in public than in a bed. Plus we get wet before it even starts." He stares at her sexy naked body.

"Oooohhhh. Sweetie, do you have any clue though where our clothes are? Especially my top?" Minori asks, probably hoping they can get dressed after this.

"The bottoms are somewhere up there..." He points to ledge above them "...your top I'm not entirely sure though, though none of that matters right now. Have I ever told you how sexy you look by the way?"

Minori blushes redder than a tomato. "U-u-u-uh, um, thank you sir. Although I never took anything before this."

"Don't worry, I won't mess with your pussy anyway."
