Shift to Kim's POV

-Come on, do it, bitch!-.

"Son of a..." You say to yourself: "He has the upper hand, if Mom discovers that I'm breaking my part she'll punish me!".

-Kim, please, this is wrong...- Cindy whines, but you hush her.

-Don't be a pussy, you're the lucky one here.-.

"And to think that it was my plan! He just wants a free ticket for nutland! You know what? I'm going to make it difficult!" And you put a childish sulk on your face, as if you're hating what you're doing. You're about to take off her top, but he stops you: -W-Wait, massage her tits first.-.

"Oh goddamn, if you want to be the boss make up your mind!".

-Kim I... mmm...- Her voice fades away when you drop her neckline, revealing her perky nipples, and you start groping. Her tits are just a bit bigger than yours, not enough to be called "knockers" but enough to cause some bother into handling them.

-Happy now?- You snort.

-Be more passionate! If-If you can...-.

"If I... Jesus Christ!".

-Mmm... Kim please... oh you're good...-.

-Can I proceed?- You play disgusted, it actually doesn't feel bad.

-Uh-uh.- He nods: -I mean, proceed bitch!-.

You discard her top...

...and toss it on the bed.

His eyes get transfixed by her naked chest, as if those two anonymous globes could be really enthralling.

-Wow Cindy, they're pretty.- He pipes out.

-Uh, t-thanks.-.

You look at her blush: is she beginning to enjoy it? And why isn't he asking you to get naked too?

-Hey!- You protest: -Eyes on me! Weren't you giving orders?-.

Your brother shakes his head: -Yeah, then, then you should...-.

You roll your eyes, this is becoming really embarrassing: -Oh I know, you want me to lick them right?-.

-Right. Lick them. Totally.-.

You do as you are "commanded", kneeling on the bed and lapping her right tit. She looks down at you and moans in pleasure...

...then she even cups her other boob!

"I knew she has a different boyfriend every night, but is she into submission shit or what?".

Then you have another flash, like the one while opening the front door. One night, when you were both drunk, she confessed to you that it was indeed the case. Not just that: she used some weird word, "raptophilia", that as Kim you didn't acknowledge but, as Tom, you know that it meant that she dreamt to be ****. This is a game-changer.

You decide to take the lead, making your way up to her ear with your tongue.

-Could you be a little less condescending, please?- You susurrate venomously: -Do you have hots for my brother?-.

-Uh? I-I'm not, I mean, I'm not really...-.

-Hey, what are you talking about?- He exclaims alarmed.

-Nothing big chief, just trying to make her comfortable.- You spit back: -Checking we're on the same side.-.

Basing on her gulp, you eventually are. With a sigh, you notice that he's agape again.

-You was telling me to take off her pants too, correct?-.

-A-ehm, correct, do it quickly.-.

You obey.

-Now her knickers...- But Cindy herself stops you: -Wait, maybe he wants to admire me a little bit... more...- the last word comes whispering as you give her a **** stare.

You then look at the tent on your brother's crotch.

-Are you doing anything about that or what?-.

He tinkers with his trousers, mumbling an embarrassed: -I was... about to...-.

Then the package is revealed. Seeing it again, you kinda miss having it. Cindy gasps, **** in her eyes. She turns to you looking for any direction, things are getting really serious and it's your brother's prick after all, but you're just eager to move on. He lasted long last time, but today you'll see. However, as you get close, he stops you by speaking with her.

-Cindy, since you like to use those lips to make fun of me, I want you to use them to make me having fun.-.

You both widen your eyes: her in fear, you in shock. The situation is already humiliating, and now he's choosing her over to you?? Her??

-What the fuck? She is just my poor imitation!- But he isn't even listening to you, too busy stroking his cock and staring at your friend, who reciprocates with dismay, half attracted and half disgusted.

You are indignant. More, you are outraged, you don't have to pretend, the pout on your face comes naturally. After what you did to him! And it was just yesterday!

-Don't tell me you're offended, bitch!- Great, now he's being stuck up. Tom puts a hand under your chin and grabs your cheeks to mock you.

-She's not even good at giving head. She told me.- You blurt.

-Kim!- She sounds really betrayed by your confession. Oh, right, you've promised it would be a secret, etc.

-Let me judge it. Come on Cindy!-.

Cindy finally makes up her mind and hesitantly swallows his throbbing tip. He moans, you just observe with contempt. After some seconds, in fact, she retreats to inhale.

-I can't do it, it's your brother!-.

But Tom is not discouraged and deigns to turn to you with a sly grin on his face: -Sis, she needs your help. Be a friend.-.

-Don't be ridiculous, she won't... Kim?!- Cindy realizes startled that you've just engulfed his length and you're starting to slide along. Watch and learn, you think, this is how to do it.

-Mmm... oh... ok, stop, stop just a sec.- You comply, you don't want to make him cum before you've reminded her of her role. Only after that their shared fantasy will end, and you will make sure of it.

-Oh my God, he's your brother!- Cindy squeals hysterically: -Kim, you just sucked his penis! It's wrong!!!-.

You share an "aw, fuck!" expression. You were so absorbed into your desires and plans that you forgot that the line you've already crossed before still exists for the others.

"Well, no more. No need to cry over it.".

But she is; and, since you want to teach her a lesson she won't forget, you are taking advantage of it.

-No Cindy, you did wrong. On the contrary, I showed you how to give a proper blowjob. Now, little brother, do you agree to let her try again, don't you?-.

He's surprised by your sudden changing of mentality, but he's not burning this occasion.

-Practice makes perfect. But she'll need your guide too. So, girls, if you please...-.

Cindy shifts her confusion between you two, halting at you and shaking desperately her head. Until now you were hampering his rave, and you suddenly became his accomplice. It's yet another blow to the perfect image she had of you. Ahh, she could never understand your motivations, even if you'd explain them. But it doesn't matter right now; what really matters is pulsing right in front of you, and it needs your attention.

-Go on Cinds. I'm behind you.- You urge her. She gulps and slightly nods, then she's another time on Tom's dick. This once, however, she won't be alone.
