You are staying at your aunts house on vacation and your cousin has been walking around with her thong hanging out and it seems like she's flirting with you, but she keeps insisting she isn't. One day she's cleaning and wearing low rise jeans with her thong hanging out as usual and you can't help but stare at her and even sneak some pictures while she's bent over. She catches you and calls you weird and just laughs it off but then she goes and changes into some super tiny shorts where you can see her entire ass cheeks hanging out the bottom. You again can't help but stare and sneak some more pictures but she catches you again and this time she starts teasing you about you being into her. She says it's not her fault that you're all horny for her, even thought you're pretty sure she did it on purpose... but you can't be sure. She shows you her ass and teases you about you being weirded out and making it awkward. It's just her ass after all and everyone has one. No big deal, but then things escalate. She notices you have a boner and she just can't help herself anymore. She starts showing off her tits, ass and pussy until you finally agree to jerk off a little in front of her. Eventually this leads to her inviting you into her bed where she blows you and rides you until you blow a huge load in her pussy.
