Not as well as Dana

As you think about what to do next, you come to a realization. Thanks to you giving Dana a 9, you have an idea of how people react to a high score. However, you still have no idea how people react to a low score, since you were hesitant to be too hard on your baby sister. But you reason that it would be better if you figured it out sooner than later, and while you weren't necessarily thrilled to subject your older sister to that either, there wasn't the same 'older sibling' instinct making you feel like you had to coddle Caitlin to make it completely out of the question. Plus, with how often you see her, it would be easy enough to issue a 'retest' to fix the score if it really becomes a problem. Still, no need to go crazy with it: just a small test will do. You can afford to be more honest in some areas.

Now committed to your plan, you proceed to fill out the relevant scores on the sheet, finalize it by adding your signature to the bottom, and take it off the clipboard. You turn over in you bed and tap your sister on the shoulder, telling her, "Alright, I'm done. Do you want to see how you did?"

Caitlin, who had up to this point been rubbing her aching bare bottom, rolls over and sit up on the bed. She eschews the modesty of your younger sister, and neglects to cover her large breasts from your view in favor of snatching the paper out of your hands, "Of course I do! Now, how'd I do...?"

Additional Notes: Sex talk was uninspired, sounded like she was phoning it in rather than actually trying. Knows how to properly lube with her mouth, could improve her Oral Proficiency with more practice.

Inspector's Signature: John Doe

Caitlin's eyes dart across the sheet, and as she reads a frown starts appearing on her face. By the time she reaches the bottom of the sheet, she is visibly upset.

"'Sex talk was uninspired?'" she reads aloud incredulously, "'Sounded like she was phoning it in'?!? What the hell, John? Why would you say that? I was doing the best I could!"

"Didn't sound like it," you said. That wasn't entirely true: you were into it at the time, but looking back she wasn't exactly as good at dirty-talking as your supposedly-innocent little sister.

"Yeah, well what's the deal with my Oral Proficiency being a 2?" she asks angrily, "If I was so bad at it, why did you keep making me do stuff with it? All the kissing, licking, sucking..."

Oh crap, that was actually a good point. Maybe you should've chosen a different score to have her 'tank' in. Well, it was too late to change it now, so you better roll with it. Thinking quickly, you tell her, "You being so bad is exactly why I kept going back to your mouth. I couldn't believe that someone with a mouth like yours could be so bad at using it, but the more I tested your capabilities the more I realized just how poor of a job you do. I mean, you couldn't even make me cum with your mouth, and I was already rock hard! I had to resort to using your ass to get off, since you also couldn't convince me to use your pussy. The only thing your mouth was good for was lubing me up, and anyone with enough spit can do that."

Caitlin visibly deflates at your improvised reprimand of her oral skills. Looking at her sheet again with a much sadder look on her face, she says, "I can't believe this... I always thought I was a good kisser. And Carter never complained when I blew him. I thought he enjoyed them."

Okay, you had to admit, it felt a little weird having your older sister just casually admit that she gave BJs to her college boyfriend right in front of you. Then again, this was right after you jack-hammered her ass with your cock, so you really didn't feel right calling her out on it.

"He probably wasn't experienced enough to tell how bad you were," you say to her, "Or he just didn't want to hurt your feelings."

"Yeah, maybe. He wouldn't know as much as an official Female Body Inspector," Caitlin mutter dejectedly. Looking over her sheet again, she says, "All I scored good in was my looks, breasts, and ass stuff. I knew there was something wrong with how my pussy tasted."

"I wouldn't necessarily say 'wrong'," you clarified, "More like, 'non-descript'. Your vagina isn't really bad, just... dull, I guess."

"Oh," she says, "Well, I guess the distinction isn't that important. With scores like this, the only thing guys will want to do with me now is anal. Or titjobs, I guess. Better get used to those."

You both hear a faint beeping sound coming from somewhere else in the house. Your sister sighs and says, "That's the wash. Better move it over. Thanks for getting this over with quick." Caitlin crawls out of your bed and walks out your bedroom door, giving you a good view of her reddened ass before it closes.

You start to feel a little guilty about how you talked to her, but you'd be lying if you said there wasn't a part of you that was enjoying having this kind of power over your older sister. Still, you figure you should at least make sure she's okay. You grab your clothes off the floor and get dressed, then head to the laundry room. When you get there though, you find that Caitlin isn't alone.

"Come on, sis!" Dana begs, her own sheet in hand, "I want to see how you did! You said we could compare scores!"

"I never said that," Caitlin retorts, doing her best to hide her own sheet from your younger sister's prying eyes, made difficult by her still being completely naked, "It won't matter for very long, anyway. I'm going to ask for a retest in a little bit, so we can compare them after that."

"Really now?" you say, walking up to the pair, "So soon after our last one? I'm not sure how much you could improve your technique in only fifteen minutes."

Caitlin's face reddens and she looks over at you sheepishly. She opens her mouth to say something, but before she can, Dana takes the chance your distraction provided to swipe Caitlin's score sheet from her.

"Hey, give that back, you little brat!" Caitlin snaps angrily, reaching out to try and grab it back. But Dana's gymnast training gives the smaller girl the advantage, allowing her to nimbly avoid the retrieval attempt.

"Not until I see what you're trying to hide!" Dana says, eyes glued to the paper in her hand. She grins mischievously as she looks it over, "Oh man, it's not looking good so far. A 4 for your Vagina, a 3 in Vocalization, and... is that a 2 I see for Oral Proficiency?"

Caitlin looks down at the ground in shame, as if she had just been caught trying to hide an 'F' on her report card, "...Yeah..."

Dana looks up at her older sister, and upon seeing her reaction the smile on Dana's face falters. "Hey, hey, it's okay," Dana says sympathetically, "Yeah it's bad, but you still got an 8 in Attractiveness, and your breasts blow mine out of the water. And you at least have a proficiency score above a 5."

"Yeah, for my ass," Caitlin grumbles, "I don't even know what I did to score that high, and now all anyone's going to want to do with me is anal. According to John, my pussy is too boring and I can't suck a dick to save my life."

"Yeah, I can't deny that," Dana says, looking at her sister's crotch, clearly unimpressed, "Your pussy's kinda... 'bleh'. But maybe if you shaved it, you could get it up a point or two in the retest. Mine's hairless, and I got a 7."

Caitlin looks down at her pubic hair, then between you and Dana and asks, "Would that really work?"

"Hard to say without seeing it bare," you reply, curious as to how she will take it, "But Dana's vagina is indeed shaven, and it certainly made using it a smooth, pleasurable experience."

"Thanks, John," Dana said with a smile, before blushing and asking, "But did you really have to say that in front of Caitlin?"

"Just being honest," you tell her with a playful shrug.

Caitlin looks down and rubs a hand over her pussy hair, and mutters, "Well, I guess you two would know better than me. It's not something I usually do, but I'm willing to give it a try."

"Don't worry, I can show you how I do it while your stuff's in the dryer," Dana says, "I'm also willing to help you with spicing up your sex talk if you want. With a teacher like me and a little effort on your part, I bet we could easily get your Vocalization up to at least a 6!"

"You'd really do that for me?" Caitlin asks, eyes lighting up with hope.

"Sure thing!" Dana replies happily, reaching up to pat Caitlin on the shoulder, "What are sisters for? Not sure what I can do about the oral stuff though... it says you need practice, but I'm not sure I'm experienced enough to help you there."

"Yeah, I'm not sure what to do about that either," Caitlin mutters dejectedly.

You are both shocked and amused by this turn of events. Growing up, Dana had always looked up to Caitlin in nearly every way imaginable, from fashion to sports to even dating advice, all of which Caitlin helped with when she felt like it. But now thanks to your scores, the entire dynamic of their relationship has been flipped on its head. Caitlin was practically treating Dana like the smartest girl in class and taking her advice almost without question, and all because Dana had an overall higher score than her. Imagine what she would do if you told her that something could improve her score. There could be a lot of fun to be had for you there.

Though... did you really want to take advantage of your sister like that? You've already been skirting the line pretty heavily with her. Maybe it would be better to let Dana have her moment in the spotlight and use the opportunity to go out on the town and really get wild with this thing.
