Rose2 is calming down again. She thinks for a long turn, and as her tears dry, a smile shines through. "I can do that. No problem. Easy-peasy, squeezy... lemon." She blinks a couple times, confused at her own mistaken phrasing. "Anyway... I can do that... if that's what you want, I can be the best imouto in the world."
"Arigato," you tell her. You stand, as if to make for the door, but she stays you by grabbing your wrist. "Hmm?" You say, turning back.
She scoots her plump little butt backwards, and gets her back propped up against the wall. Spreading her legs, she says: "Ally... being an onii-chan is a pretty big job too, isn't it? Aren't you gonna fuck your little sister?"
All these girls treat you like you're the nymphomaniac here, but they're always the ones begging for dick. It's crazy.
"I could do without the nii-chan stuff," you say as you get back into the bed with her.
She laughs. "What, you don't like it? I know Amber calls you Daddy -- and that's ten times weirder!"
"I don't like that, either."
"You're so lame. AND a liar~"
She boops your nose.
You swat her hand away. "Stop that."
"Liar, liar~" she chants in a sing-song voice. "Nii-chan is a pervert, I know he is!"
You cup a hand across her mouth to shut her up. Her eyes bug out in fright -- and then they smile, glimmering. She pokes your forehead. When you let go of her mouth again, she says: "do you remember, the first time you had sex with me?"
You nod. "What about it?"
"You put me in a mating press... that felt SO good, Ally. That small little karaoke booth and just the two of us, with you forcing yourself on top of me... and the way you--" she gulps. "The way you came inside me without even *caring* whether I'd get pregnant... or anything else..." she strokes your chest. "I wanna try it again... just like that."
You give no response to this, just stare down at her as she strokes your chest some more and smiles at the memory. When finally she realizes that you haven't responded, she glances up, confused. "Ally? I said--"
You grab her roughly and spin her around, forcing her onto her back. You crawl over her, propped up on her elbows, face above hers. "I heard what you said," you tell her.
"A-Ally--"
You drown out whatever else she was going to say with a deep French kiss. You probe her mouth with your tongue, roughly, and wetly. In her fright over your sudden forcefulness, she hiccups a couple times. It's cute. She's a cute girl. Overfed, obnoxious, occasionally bratty, always weird, and dim bulb to boot -- but cute regardless. You like fucking her just as much as she likes getting fucked by you. Driving your cock in and out of her womb and dumping a load inside it at the end... it just feels natural, little sister or not. She's too cute not to soil with your cum like that. That's the kind of cuteness Rose2 has: the kind of cuteness you want to stain with jizz.
You get your hands under her kneepits, and force her calves back over her torso, doubling her up. The cotton of her panties, patterned with little cartoon strawberries, goes taut. You can see the roundness of her ass and the plumpness of her mound. With a flattened palm, you rub that mound of hers, reveling in the way it squishes and gives. She can only stare helplessly at the way you grope her. Her bright, wide, innocent eyes are so adorable. She's got the pussy of a little sister, all right: puffy and a bit immature, sweet-smelling and ready to plunge into.
You grab her panties by one of the legholes and tear them. Sccrr-rrchh, just like that: you rip a hole in her underwear that reveals the bubblegum cunt she begged you to fuck. The torn garment hangs in shreds around her crotch.
"What the heck! Those were my favorite pair!" She whines.
"Be quiet," you snarl.
She makes a little squeak, and then shuts up. No more speaking out of turn.
You quickly get naked from the waist down, and when she sees your veiny dick bobbing in the air, her eyes glaze over. That's what she wanted, this hairy meatpole of yours -- big brother's big dick, ready to ram into her and mess her up. Getting on your haunches, you squat over her. Her thick butt and thighs are a perfect pad to support you as you line your prickhead up with her oozing, tight little honeyslit. She's still, after all the times you've filled her with your dick, got probably the tightest pussy of anyone in your harem. It's actively painful to get wedged in at first. It constricts your dick with such vicelike tenacity that it turns the shaft an angry crimson. That crimson color is such a lewd contrast to her pale, tiny pussy mound that it only makes you even harder. Rose2 bites her lip, trying not to scream with the pain of that initial penetration, and you grunt as you press down on her with your entire weight.
The tight ring of her cunt loses its resistance -- all of a sudden you sink inside her body, half your dick getting swallowed up in a single stroke. Once you're in, you're in, and it becomes so much easier. The difficulty of that first pump is so deceptive, after all -- inside, she's as soft as velvet and so fucking wet that you feel like you submerged your dick in a hot puddle. The sticky walls of her vagina cling to every ridge and bump of your cockshaft. Tight little Rose2's cunt has truly conformed to the shape of your manly dick. She's as easy to fuck now as anything.
Rose2 is in her own private heaven. Her eyes roll back and she grabs the edges of the blanket up by her head, holding on for dear life. Her own knees knock repeatedly against her own face as you begin to really fuck her. Her body jiggles and shakes and shifts beneath you, such a lewd sight to drink in. But her cunt, her silky, grippy cunt, is all you care about. You thrust and rut inside her like a beast, with your tongue lolling out. You make deep, guttural growls of pleasure. It's a picture-perfect mating press, just as she requested. This position allows for total penetration -- your entire cock, up to the root, stuffed inside this hole that's way too small for it. After breaking open the entrance of her cunny-chute, busting through her cervix is no bigger problem, and you have zero reservations about fucking her right down to her womb. You're well aware that when you cum, the head of your cock will be in there -- peeking up past the mouth of her uterus. Yeah, you'll piss a wad of spunk directly into her baby room, and the force of gravity will keep it sloshing around in there.
She must be thinking along these same lines herself. Her face is contorting into a mask of obscene, mind-destroying pleasure. This ahegao is for real -- having her big brother rape her womb is making her cum as powerfully as she ever has before. And what she says might be a hentai cliche but she means it whole-heartedly: "Cum... cum inside my babyplace, onii-chan! Please cum with your dick and knock up your little sister!"
When this pushes you over the edge and you start to squirt your seed, you smile -- an evil, perverted grin of sheer debauched enjoyment, as you fill this pink-haired slut with rope after rope of gloppy, sloppy jism. The mating press is great because for as much as you cum -- and you always cum gallons -- not a drop leaves her body. It stays deep, deep within her, where it belongs, filling her completely with your milky load. It's also great for this reason: when she cums with her candy-smelling cunt, she's cumming not on you, but all over her own body, and all across her own face -- soiling herself even further.
As at last you feel yourself emptying, you let her legs come back below her hips, and settle into a true missionary with her. Your load begins to seep out from her body, all around your crotches, and down to the bed below, as you make out. You've made a terrible mess of your clothes, the bed and the room. You don't care. You fuck her slow and gentle, then, and she whispers over and again: "Nii... chan... nii... chan... I love you... Rose2 really loves you a whole lot... so please take care of her, okay?"
"Nii-chan loves Rose a whole lot, too," you say back. You swipe her hair from her face. "Don't call yourself Rose2."
"I'll do my best..." she murmurs, close to passing out. You kiss her again.
