2T4U/Jack/Raped Melony/Missy's room (P)/gentle/Tell her you want to pee on her too
Sometimes, the simplest answer is the best. "People usually do it on purpose. It's fun to pee on each other."
"Do you want to pee on me?" Her face scrunched up and she didn't look too happy about the idea, but it was distracting her from her embarrassment.
"Would that be okay? You peed on me already, so I 'd really like to pee on you now."
"I guess so. Should we go to the bathroom?"
"No, we're already going to have to wash your sheets so lets just do it here."
"Oh, okay. I guess that's alright."
You climb up on her bed and stand over her. She sits up cross-legged and turns her face away, closing her eyes and mouth tight. It's a little difficult with your growing erection that's only getting stronger with the excitement of what you're trying to do, but soon you get a stream going to shower your 6 year old sister with your piss.
Missy giggles when it hits her chest. "It's warm." She raises her hands up when you aim for one of her nipples. "Hey, that tickles!" She opens her eyes and smiles up at you. You flick the stream up toward her face and she ducks. Realizing you got her hair wet, she laughs and puts the top of her head under the stream to wet her auburn hair like she might in a real shower. Her hair is only partly wetted when your stream dries up. "Aw. you're already done? What other sex games can we play?"
