A sister's quirks

Obviously, a sister like mine must have some defining personality traits. After a moment of thought I decide to give her one.

"Alright bro, I'm going to take a shower here," she says as she raises a foot and steps into the bathtub. She begins turning the water back on. "Just watch me, okay?"

"Okay sis," I nod.

Jets of water sprinkle out of the shower head as my sister lets it pour over her body. She continues to clean herself for a few seconds. A dab of body wash here and facial foam there, and it was looking like any normal shower. Or at least, as normal as a shower including a brotherly voyeur could possibly be. A brother, mind you, that was visibly rubbing himself against the wall as his sister left the door and curtain open to show off her naked, lithe body to his two hungry eyes. This wasn't just great. This was a miracle of the highest caliber.

Then, suddenly breaking the ordinary routine that had been sustained thus far, Jessica lifts up her leg and plants her foot against the wall. Her calf and thigh are now at a 90-degree angle but grow wider apart as she pushes against the wall, stretching her leg across its length. She continues until her foot is now nearly above her head. I watch as, with as calm a face as ever, she turns backward to grab the shower head. Then she proceeds to bring it under her now exposed pussy and spray it clean.

"Sis, is this how you normally wash yourself?" I ask testily.

She looks at me and says casually, "Well, yeah." Shrugging, she continues spraying her pussy with jets of water with one hand while mushing against it with another. "It's just how I do it. Don't ask."

Obliging, I don't. Instead I focus on her pussy, which needs a trim. I think that it would be better to see it bare.

In the next second her hair disappears with a poof, leaving her pussy completely hairless and smooth. I grow hard.

She finishes up her pussy cleaning routine, but that isn't everything yet. Placing the shower head back in its place, she now pulls her ass cheeks apart, exposing her butthole. "Alright..." she murmurs, as she lowers herself. Sitting her butt against the bathtub floor, I hold back a chuckle as she begins dragging her ass across it, like a dog on a newly furnished slab of rug.

She moves forward. Scree, scree.

Then she moves back. Scree, scree.

Then so on and so forth. Ripples begin forming throughout the pool over the basin with each motion as she tries to get her butthole as clean as it could be with each shimmy. She looks completely silly, and I let slip out a chuckle. Suddenly I hear Mom's voice calling us down for breakfast. I check the time, and realize school is starting in a half-hour. I look back to my sister.
