No, she should just enjoy herself.

"No, it's fine, just... Do what you want. You should enjoy yourself," you say, your face burning. You don't think you have the composure to give her instructions!

Hina smiles gently down at you, a light giggle escaping her lips. "You're sweet..."

She runs her fingers along the length of your shaft, fingernails giving a light scritch up to your throbbing head. Her fingertips explore your foreskin, her face flushed and her breath coming out heavy. She's staring at your turgid member, eyes wide with fascination.

"It's... kind of beautiful. Like a pool noodle... Only alive, like a pretty fish..." she breathes, her fingers wrapping around the top half of your shaft. She seems to be just enjoying the feeling of it in her grasp. "It's beating, like a heart... And it's hot, even though you were just in the pool. It's smooth, but textured and... hard, but soft too." She giggles nervously. "Like a pool noodle or pretty fish!"

She leans to the side a bit, her interest in your hard cock increasing. Seems the more she touches it, the less like a wild animal it seems to her.

"What's this gunky stuff coming out of the tip? It doesn't look like cum or pee..." she asks, blushing at her own question.

"Uhhh, it's... pre-cum. It happens when a guy gets really, really turned on," you admit, reaching an arm up to cover your eyes in shame at what you just told her.

She lets out a breathy "Wow..." Her fingertip rubs and spreads the pre around your head. She seems to be gaining confidence as she realizes how fun a cock is to play with, but... You're honestly not sure how much more of her exploratory teasing you can take. Should you tell her to stop, hold it in as long as you can, or just let your boys swim?
