Well, since she did offer...

You eye her body and you spring up a circus tent in your pants that gives you away. She smiles with just half her lip, and she puts the orange down. You try to ask her if it's safe to fuck her but she's busy tearing the clothes off her body, her flannel shirt popping open like a bag of chips revealing her pudgy body and junoesque breasts that are restrained with a gray lacy bra. She only replies half distracted. "Oh, what? Oh yeah sure, it's fine, just fuck me already." It doesn't reassure you much, but you forget about it once she drops her shorts. Her matching panties cling to the form of her pussy tightly, and there is a dark, moist stain that is steadily getting bigger. You can practically smell it from here. She walks towards you swinging her wide, curvacius hips from side to side, watching you with burning ochre eyes. You're unsure if it's still her or if she's given in, but her motives are clear and you don't mind that. After all it is safe. She said so herself. She thrusts her body against yours dominantly, sandwiching you between her and the wall. She kisses your non resistant lips, her long gray tongue working its way into your mouth sloppily, while her fingers sneak through the waist of your pants and into your underwear, fondling your cock. But she breaks away, and walks back to the couch. With a single movement she pushes the rubbish that was on it to the floor, and she jumps on the couch, bouncing for a moment like on a trampoline, before turning to you with her legs spread wide open and a come hither look on her face.

"C'mon stud, come over 'ere an' fuck me silly."

You can still taste her in your mouth, the taste of oranges, but also something else, something else you can't put your finger on, something that the more you think about the more you feel fuzzy and warm and... Good. You follow her to the couch, gradually shedding yourself of your shoes and trousers and eventually underwear, revealing your pulsating member and bulging balls that swing side to side.

You climb on top of her on your knees, your body towering over hers, and you grab a handful of her pudgy hip flesh, one hand on each side to lift her lower body to cock height. You move her lacy panties to one side, revealing her smooth tight pussy to the air. Only a tuft of swirly pubes grow, just above the entrance, almost like a doormat. She nibbles her lip in anticipation. That's when you ease it in. If it were dry it would be rather difficult, but her slick femcum helps you enter with no resistance, so much so you accidentaly slip your entire length into her, hitting her cervix with a **** only an accident can make, but she squeals in pleasure, her eye twitching with its eyelid half open. You star to pound into her, sliding in and out almost too easily, as if her insides were covered with butter. The lack of friction is a little unfortunate, but it still feels amazing.

But you start to feel funny. Your thoughts seem to get simpler and simpler. You catch glimpses of an idea of what's happening, but they flutter away at just how good it feels to be fucking. Fucking, fucking, fucking. Fucking. Fuck. Fuuuuuckkkk... You don't notice yourself changing, your skin turning gray, your fingers painfully changing into claws... She notices, but she doesn't care, squealing away happily at having a cock fill her snatch. You thrust harder and harder, almost violently so, clutching her hips ever so tightly, your cock as if hitting a button that causes pleasure over and over again.

"Oh yeah stud, cum with me, cum in me!" She manages to say between her happy, full grinning moans. She orgasms first, a high pitched squeal as her body spasms, her back arching and her hips thrusting upwards, closely followed by your orgasm, where with a final thrust that you keep hold of for a couple moments, you shoot your seed into her, filling her up like a cum balloon. Cum sprays from the seal between her cunt and your cock. You gnash your teeth and growl like an animal. You spend almost no time taking your cock out of her, and you're about to flip her over and ravish her other holes, when her sister bursts in through the door, a gun and a cricket bat in her hand.

"Oh for fucks sake, not again!" She spends no time firing a shot at you. It pierces your skull, spraying blood all over the wall behind you. You slump off Stacey and onto the floor, twitching occasionally.

"Oh you're always like this! You never let me have any fun!" She yells back at her sister.

"You know you're not supposed to turn them! I can't feed em' all oranges! You know this!"

You slowly black out, the argument between the sisters slowly fading, until eventually you can't hear them. You close your eyes softly, and you give up the ghost.
