Talking to Katy

You walk into your bedroom, feeling exhausted.

"I'm sorry," Katy says pleadingly, "She makes me do that. But she's able to do it because I like it."

"Well, it's a free country. Wait, is this a free country?" you ask, "No matter. You don't have to do it with her if you don't want to, Katy."

"But she has pictures of me," Katy says, blushing and looking down.

"Ew, why would a woman **** another woman like that?" you think out loud, not having realized your big sister was that sadistic. "She won't do anything though, really. What's she going to do, admit she was having **** with her little sister and blackmailing her into it? Our family's had enough drama. Just tell her to go pound sand and that you're going to sleep in here with me and Heather."

Katy doesn't look sold on that proposal, but the words do resonate with her anyway. Everything in your family is always dramatic with hurt feelings and emotional manipulation, slammed doors and guilt trips. You realize this summer you've been breaking away from that, working a job, getting a girlfriend, living your own life. Even if Mom tells you to move out from her house, which you wouldn't be surprised to have happen given that her motto has always been "My way or the Highway", you'll just deal with it. You're not going to play this awful games of guilt and manipulation anymore.

"Whatever happens, I'll take care of you," you continue, "And besides, I've gotten Ellen pretty close. She is obsessed with my cock."

Katy laughs at that, evidently having not been expecting it. "I love you, but I doubt that. She won't even let me use my fingers on her. She's afraid of even small things in there... and yours is way bigger than average."

You shrug. "I think she's fascinated as much as she's afraid. And she's just afraid of how far she'll go once she starts," you say, "Anyway, if she won't become a size queen for me, then fuck her. Except not literally, but that's her loss."

Katy looks amazed at your confidence. Ellen has bossed you around for years, and apparently she's really had her way with poor Katy. You'd never imagined even Ellen would **** her own sister like that, but it makes you all the more determined to help Katy now. And give Ellen her come-uppance, right into her womb... if you can manage it.

"So you'll keep me safe from Ellen? And Mom?"

"Y-yeah," you say, surprised at the extent to which she feared them, "You know it's all just drama and emotional manipulation with them. Let's just become adults and not play their dumb games. You don't have anything to worry about them."

Katy smiles. You feel better too. It was scary to have Ellen seem to take Katy away from you like that, to demonstrate her power and make you not feel like such a big man for a while. But it was all smoke and mirrors, Katy likes you better because you'll actually protect her, and don't just see her as a pawn.

"Okay," she says, laying down on your bed on her back. Totally naked as always. "I didn't entirely dislike what Ellen does to me... part of me loves it. But... I like how you treat me a lot better. She makes me cum, but she doesn't make me feel safe like you. If you keep me safe, then I'll be your ****. You can do anything with me, big brother."

You grin and your cock starts to stiffen. You wish you could say this was your brilliant plan, that you'd played it this way to make Katy want to be your ****, but you know most of it comes from some urge deep inside her. This summer you've just been a halfway decent guy as events progressed and protected her a bit, and combined with her **** fetish, that makes her want to be your ****.

"Anything?" you can't resist asking.

"Anything," Katy says softly, closing her eyes as she lays there, very much offering her naked body up to you. The door cracks open and Ellen is blatantly spying on you. Your cock is hard now and you make a show of shaking it, which seems to thwart any intention Ellen might have had to barge in and enforce her earlier threat. Like you told Katy, she can't control you. Even if she could, she wouldn't want to anymore. Now she just wants to watch you use your big cock and probably fantasize that you're using it on her. You have both of your perverted sisters totally figured out now.

But what to do with a naked girl who will do anything you want? You climb on the bed on your knees, positioning yourself over your sister's face, looking down over her ripe body. Ellen looks horrified at this dominating, humiliating position you've put her little sister in and shakes her head at you, as if saying "Oh don't you dare". Of course, this only makes you want to do it more.

"Will you lick my balls, ****?" you ask aloud lewdly.

"Of course, master," Katy says almost gleefully, and without any hesitation she leans up and you feel her lips around your sack, shamelessly taking her big brother's balls in her mouth. They're so big she can only fit one at a time, but the pressure around your flesh feels amazing. She was so high-strung at the start of the summer but now she's happy to be sucking on her brother's balls. She squeezes them with her lips and tongue and you grown in pleasure.

You hold your body over Katy's, letting your cock flop over her chin and point at her smallish breasts while you lower your head between her legs. Your see little sister's bald pussy, totally forbidden to you for so long, but now she spreads her legs eagerly, opening up her tight coinslot labia lips and showing you her pink. You lean in and lick down Katy's slit, already glistening with her excited wetness.

Her lips tug at your balls as you lick her slit. This position is too much of a stretch... literally... but conveniently, your cock is much better positioned with respect to her mouth. You press your cock against her lips, finding she opens her mouth instantly and you slip into a 69 with your little sister. You press your tongue inside Katy's feminine folds, tasting her as she moans into your cock.

You lick Katy as she sucks your cockhead with soft whimpers. Her hand goes to your ass, pushing it, as if begging for more cock. Well who are you to refuse? You look over to the door to check on Ellen and find your big sister practically falling into the room, she's so obviously watching you 69 with Katy. Your little sister taps your ass again impatiently and you give her what she wants (or needs?) sliding half your cock into her mouth, thinking this will please her, or even **** her. You feel her throat around your cockhead just barely as you shamelessly feast on her pussy, eating that cheerleader cunt you've always dreamed about. You jam your tongue into her pink depths as she sucks your cock with her vacuum mouth.

You think this is enough to satisfy both of you, but she taps on your ass again. She wants more cock. You look over to big sister Ellen, who shakes her head no imperatively. Maybe she thinks you'll **** Katy, but you rather suspect she doesn't want her little sister to be able to deepthroat your big cock before she can. It will make her jealous.

So of course you go for it. You give Ellen a smug grin and plunge your cock into Katy's mouth. You feel her tense up and then her throat is all around your shaft. But then she relaxes somehow. She didn't throw up, she took your cock. Maybe she's been practicing, maybe she just really wants to deepthroat. Horny as hell, you start fucking her face, pretending her mouth is a pussy. It really feels like a cunt, you can push your cock as deep as you want. You go balls deep, your cock all the way in Katy's throat, your balls on her chin. You look at Ellen and her mouth is agape. You nod confidently resume fucking your sister's face hard. Katy doesn't try to stop you, and you can hear her moaning as you ram your cock in and out of her mouth with animal lust.

You go back to licking her teenage pussy, which is soaking wet by now. You find her clit and flick it with your tongue confidently, sucking on her womanhood noisily, as if you own it. You buck hard against her face, sliding your whole ten inches in her throat again and hearing her gag. You think you've gone too far but then you feel something on your balls. She's tonguing your nuts with your whole shaft in her mouth. You lick her clit eagerly and she starts to shake, having a powerful orgasm under you.

You pull your cock out, hearing her gasp for air as she cums at the same time, her body also reduced to a primal sexual state. You keep licking her hairless clit as she cums, squirting her juices, gasping for air, rubbing her tits against your chest, licking your cock and moaning with pleasure. You shove your cock into your sister's cunt-mouth one last time, making a delightfully guttural slurping sound as you penetrate her fully, then pull out and start to cum hard, painting her face with rope after rope of your sperm.

You collapse on your back next to Katy and hear footsteps. You almost panic, but it's not Mom back early, it's Ellen. You'd forgotten about her in your lust. You ignore her and look to Katy. "It's okay, she won't tell mom," you say, reassuring your little sister and making her smile.

Katy's face is an absolute mess. She has slobbered all over herself from your intense face-fucking and now you put a layer of cum over all of it. She gives you goofy smile, obviously not the least bit ashamed of the perverted mask you've given her.

"Amazing deepthroating," you say, to excite both of your sisters, "I love fucking your face."

"I love you fucking my face, master," Katy says sweetly with a big grin.

Ellen is standing there naked over the bed, her wannabe dominant facade totally gone. "Can I... suck it too?" she asks you. Without even breaking a sweat, you've broken your big sister. And she totally deserved it, so you don't feel guilty.

"No," you say, "You've been a bitch for so long, you have to earn the right to suck my cock."

Ellen nods! Katy gasps at the transformation, but you feel like you've earned this by playing your cards right, and now you want to enjoy it. "Clean all the filth off Katy's face, then MAYBE I'll let you suck my cock in the future."

Ellen just kneels down and starts licking her little sister's face, which is covered with cum and slobber from the brutal face fucking. Katy acts like she's at some kind of fancy spa, relaxing on her back on your bed as her big sister licks her face clean. You realize that despite her **** fetish and bisexuality, Katy might not have liked submitting to her sister. Or maybe had a love/hate relationship to it. She's sure smiling triumphantly now.

"You like Ellen's new position huh Katy?"

"Hell yeah," your sister says as Ellen scoops up your cum off her face and hungrily swallows it, "Not so hot are now you now big sister?"

Ellen blushes and looks down. "I suppose I deserve it after how I treated you for so long."

"Damn straight," Katy says, "Or damn lesbian, maybe?"

You and your little sister laugh at her dumb joke. Even Ellen grins then makes her face go expressionless.

"Hey, don't stop licking, big sister!" Katy yells, and Ellen resumes, all the while stealing glances at your cock.

Thing's are going to be even more interesting around the apartment... if Mom doesn't find out and throw you all out on your ****-loving butts.
