it's always older sibling who's a mean pervert x sweet innocent little sibling. what if your little sibling is a bit of a slut. still a sweetheart - still fun and affectionate and always looking up to you, but. they're just a bit of a slut. skimpy shorts in the hot summer and tinted chapstick and physically affectionate in a way that would be cute if it weren't for those fucking big eyes and pouty mouth and you can't figure out why it makes you so fucking angry to see them in someone else's lap, during those little summer parties they throw when your parents are gone, but it makes you angry to think that someone has probably been touching your baby sibling. you push it out of your mind.
it just feels like- like they're looking at you differently, lately. like they're looking longer and closer with a feeling you're scared to try to pin down. they're touching you just as much as always, but it's... different. it feels like maybe they want something from you. but that can't be true, you must be making things up, must just be projecting this weird sick want that won't leave you alone.
and then one night you wake up to the faint creaking of your bedroom door and soft footsteps across the carpet. you'd been sleeping deep - you're out of it and not really thinking, so when you hear your younger sibling say they had a nightmare, you forget to question it, forget that they haven't snuck into your bed out of fear in years at this point. you lift the covers without opening your eyes, feel the mattress dip, and you drop your arm, expecting to feel - something. pajamas, maybe. a tank top. you don't. you drop your arm and you feel skin, you feel skin and you move your hand down because you must have just landed in an awkward spot but it doesn't change, it's just smooth and warm and fuck, fuck they're naked and before you can pull away in panicked arousal they grab your wrist and drag your hand lower and you think to yourself oh. oh, this was always going to happen, wasn't it?
