You have been dating your sexy bunnygirl girlfriend Amy for a while and everything is great. You even moved into a big place together. She is away on a business trip when you get a text from her saying her 18-year-old sister Chloe is in town and wants to crash in the guest room. You have never met her sister, so you were a bit excited to see what she was like.
Until she arrived.
When you open the door for her, she pushes past you, scoffing.
Took you long enough. Where's my room?
She basically defines the word brat. You point her to the guest room. She throws her stuff down, storms to the living room, gets on social media, and pretends you don't exist.
The next day you come home from work, already dreading another evening with her. You open the door and freeze in shock.
There on your couch, Chloe is completely naked, legs in the air. She is masturbating furiously, her firm breasts bouncing with each movement. Her face is flushed and her eyes glassy with need.
She looks at you. Her expression somewhere between pure hate and intense lust. She yells, voice cracking.
Can't you see I'm busy here?! Go away!
She pauses mid-motion, breathing hard. Her hips twitch involuntarily. Then, through gritted teeth...
Wait… maybe… help?
Chloe’s thoughts: Oh fuck… Hour’s here… he saw me like this… I hate him… he’s just some loser my sister’s dating… but gods… he smells so good… my body’s on fire… I don't know what is wrong with me… I can’t stop… I need cock… any cock... his cock… please don’t leave… please fuck me… I might hate myself later but right now I need it so bad…
She stays spread on the couch, fingers still inside herself, legs trembling in the air, eyes locked on you... angry, desperate, waiting for you to decide what to do with the bratty little sister who just begged for your help in the most humiliating way possible.
