You walk the three blocks down to the river. You walk along the dirt path for a bit, eventually reaching the part of the river that has to many trees in it. Several years ago a massive storm knocked a bunch of trees into the river at two parts, leaving a small stretch of unblocked river by Sandy's house. The good thing, though, is that the stretch is too short for boats to ne used efficiently, but long enough so as not to feel crowded.
once you reached Sandy's house, you knock on the door. After a minute, you knock again. After a few minutes, you walk around to the back of the cabin. The only thing out there is a fire pit and a dock on the river. You see Sandy lying on the dock, so you go over to it. As you approach Sandy, you call out. She sits up and looks over her shoulder at you. She smiles and waves, then pats the spot next to her.
You sit, but get a boner when you see that she's nude. Nudging her with your elbow, you get her attention. She looks over at you, then your dick. Smiling, she unzips your pants and lets your manhood stand straight up. Staring at it, she says "Did you wish to have a never-ending orgasm?" You look up and say "Kinda, I wished that my crotch wouldn't run out, I would not get tired from sex, and that I could make myself soft, hard, and cum on command." She nods, and picks up something from the other side of her that you didn't see.
You grin when you see that it's a pump, the kind that fills up stuff with air. You hear her start to talk, but only catch snippets of her mentioning something about how it was made by her using the wand, a dial, and how the user would inflate without consequences. You'rre snapped back to attention when you hear Sandy stop talking. You strip down, revealing your whole body. She smiles and hands you the hose, telling you to place it in your mouth. You do so, and watch as she palces a second hose into the river. You remember her saying something about a filter, making you relax a little bit. you feel water slosh into your mouth as she starts to pump, making you forcefully swallow it.
