Might as well.

You nod. "Sure, we can go for a walk..."

She smiles, floating giddily in the water. Hina swims to the edge of the pool and reaches a hand to pull you out. You're momentarily distracted by her huge breasts flimsily contained by her bikini top swinging and hanging from her chest as she leans over the pool. Blushing a bit, you take her hand and let her pull you out of the pool, though you have to expose your cock to use your other hand to help climb out.

You stumble a bit, but Hina catches you. Her breasts squish into your chest and you feel your penis harden against her soft thigh. Only a thin, flimsy bikini is between her bare flesh and you, and Hina seems to have that realization too. She can feel your dick against her thigh and she bites her lip, blushing in embarrassment. "Um, c'mon, let's... head out." You're grateful for her changing the subject.

As you head out of the pool, and you can't help but note her bikini-clad tits wiggling with each step. Hina grabs onto your arm, hugging it between her breasts. She even puts your forearm under her bikini top, pretty much giving your arm a tittyfuck! She looks embarrassed but overjoyed to be walking with a boy, even though he's naked and she's in a bikini. Several girls out in halls look at you two and you can help but cup your cock with one hand, though under their gaze and with Hina's softness on your arm, you can't help but feel your dick get a bit harder against your palm...

Hina giggles. "This is nice... I've never been on a date with a boy before!" This is a date? Hina pouts though, reaching to tug at her bikini strap. "I wish I could take this off... I've heard some people go on dates in matching outfits... it'd be nice to match yours... I've had a few wardrobe malfunctions at pools, so maybe if I just think of it as skinny dipping, it would be less humiliating to be naked out here..."

Your face burns at the implication. But if Hina so much as flashed a nipple, you'd get a penalty from Monokuma...

"So, um..." Hina looks up at you from where she's attached to your arm, a shy smile on her blushing face. "Where did you want to go?"
