You walk in on your goth step-sister as she's getting dressed and she looks so hot in her mini skirt and fishnets. You just waned to hang out cause you were bored but she notices you get hard and calls you out on it, then she asks to masturbate together. She shows off her cute pink butt plug and starts encouraging you to stroke your cock. She starts playing with her clit as she tells you how hot you are, and teases you about how you want her to ride you and get cream pied. She plays with her butt plug and bounces her ass for you, then she starts to play with her pussy again and asks you if you're starting to get close. She wants to cum together, so she gives you a countdown from 3.
