your parents hiding the fact that your perverted older sister is out of prison, they didn't want to stress you out while you were away at college. they thought the restraining order would be enough.
waking up to the heat of a body pressed against your back. to a mouth on your neck, to fingers teasing over your hard nipples. to the feeling of dampness forming between your legs. you gasp, but when you try to speak to alert your roommate in the other room, you feel a cold blade press against your neck. your older sister just laughs and pinches your nipple. she holds the knife there as she gropes your tits with her other hand, moaning into your ear. she licks up the side of your face, tasting the tears that have been falling for her.
she moans deeply as her hand trails down your body, landing on your soaked panties. you bite your lip as she quickly, pushing you onto your back and holding the knife against your inner thigh. you look away, closing your eyes as she cuts the panties off. she rubs the hilt of the knife over your clit as she makes you take her fingers, one by one. one for every year she's been away. she warns you not to cum, not until you've taken all five fingers.
she pulls out and slaps you when you cum when she's only on the second finger. she shoves her fingers down your throat when you try to apologize, until you're gagging and choking. her fingers are dripping when she finally let's you breathe. though it's only a moment you get to catch your breath. she doesn't give you the chance to adjust to three fingers, she skips right to four. it's too much, you feel like you're being torn in half. but she forces you to take them. you don't dare to make another noise as she moves the knife back to your neck as a warning.
but she pulls out against just as you adjust to four fingers. you look at her in fear, worried you made a sound without knowing, but she straddles you. she thrusts her cunt against yours, before riding you roughly. your mouth falls open pathetically, your body is brought right back to the times you used to do this together as girls. how she used to make you cum underneath her like this every night for hours and hours. when she leans down towards you, you take her tongue greedily, sucking it like you've been starved of it for years.
she holds you close, praising you, telling you she's never letting you go again, that you're her's, she'll kill you before she'd lose you again. she bites into your shoulder as she cums all over your pussy, marking you right where the scar she'd left years ago was starting to heal. right where she always bites you during her orgasms.
she doesn't need the knife enough when she's back to fucking you on her hands. you take her fifth finger like the good little girl you were born to be for her. she let's you cum when you promise you're all her's again.
