Bored Little Girl/Pipe/Little boy ask for pee
A bit surprised by his sudden request, you nonetheless accept and nod to him. Thankfully, you had plenty to drink before coming. The both of you adjust positions to give you a clearer shot, and you move your hands down to spread your lips open. You've never done this before, so it takes a bit to start, though your stream is strong once it does start. It hits him square in the face, him unprepared for your full bladder's force. He corrects though, and moves his mouth to catch your pee.
Your stream flows into his waiting mouth, his tongue lapping it up. He seems to enjoy it. Much of your pee splashes out of his mouth though, as he can't manage to swallow all of it. Soon enough, you both end up with a sizable puddle underneath the both of you. The boy gasps for breath as your bladder eases and you begin to finish, though he almost looks kind of disappointed.
