Cleanliness Inspection

Repeating the magic word in your head, you say,

"Whoa, relax. Whenever you take a shower, you always ask me to come in and make sure you didn't miss any spots. You ask me to examine you everywhere and make sure you're clean. We've been doing this for years, and you've never been bothered before. Remember?"

She looks at you confused, as if she's about to say something. She freezes, then slowly closes her mouth. A split second later she smiles warmly at you.

"Oh right! Jeez, I don't know what I was thinking. I guess it totally slipped my mind. Oh, but if you don't mind, I'd appreciate it if you would hurry a little bit today, please? I've got a job interview later."

With that, she turns to you and drops her towel, revealing her naked figure to you. You stare at her perky breasts, still wet and glistening from the water still clinging to her skin. A few drops of water fall from her hair and slowly roll into her cleavage. You follow the drop down her tight body, past her navel and down to her clean shaven privates (which, at the moment, were not so private).

"Hey. Hello? Anyone there? What's up with you?"

You pull yourself back to reality and exclaim,

"Huh?"

"What are you doing? You can't really tell how clean I am from over there, can you?"

"Oh, right."

You walk over to her, and put your hands up to her breasts.

"Well c'mon, what are you waiting for? Feel to see if they're clean." She said, slightly impatiently.

You bring your hands to the supple flesh of her tits, and start massaging around for a minute. They're warm, soft, and because of the small amount of water, slippery. You often slightly catch her nipple, grazing it multiple times. You glance up a few times, only to see her looking into the mirror seemingly deciding what outfit she's going to wear. After a minute or two, your sister gives you a stare.

"Well?"

You stop. "Uh, well what?"

"Are they clean?" She asks, almost disinterestedly.

"Oh, yeah. They're clean." You say stepping back. You both pause for a moment.

"Aren't you forgetting something?" She says, somewhat mockingly.

You look back, visibly confused. She sighs, slightly exasperated.

"What's up with you today?"

She turns around and begins putting a bra on. You've got a nice view of her ass now.

"Hello?" She says, not turning around.

"What?"

She sighs, and gropes her ass cheek. She then lets go, letting it jiggle around.

"Are you going to check if my ass is clean?"

"Oh, right."

She giggles. "You're acting like you've never done this before."

You walk over and get down until your face is level with her ass. You take a handful in each hand, and start rubbing. It reminds you of kneading firm dough. You can see the pink tinted anus between her cheeks. Deciding to give in to an urge, you push your face into her crack. Your nose presses up against the hole, while your mouth rubs near the crotch. The recent hot shower, combined with the humidity, makes it incredibly warm and moist. But you did have to admit, it was very clean.

"Almost done back there?" Your sister asked nonchalantly.

Removing your face from your sisters ass, you looked up to see she had already put a bra on.

"So is everything spotless back there?" She said, turning back around.

"Oh yeah. It's great."

"Thanks again. I know it's a little annoying, and you probably hate running your hands all over me like that, but I really appreciate it."

"Really, it's no problem."

She smiles at you before turning back around to finish getting dressed, her ass jiggling slightly with every step.
