You are spying on your sister, Katy Faery, as she chats on the phone with her friend in her room. “Oh my God, he is SO hot.” You overhear your sister talking to her friend about this new guy in school, and all the things she would let him do to her. Katy gets off the phone, and sees an ad for a “kinky dating site”…and she decides to sign up. You get the idea to run to your computer and make an account, too. You spy on your sister again as she is checking the dating site, and Katy sees that she has a new message and friend request. She’s surprised to have received anything so quickly, and immediately opens it up. Katy is excited to see that the boy she has a crush on at school made a profile and messaged her. (Your Sister is completely unaware that you created a fake profile, and sent the message yourself.) Katy is on the phone with her friend again, and she tells her about the kinky dating app and the “guy” that messaged her. Katy tells her friend that the message said that he wanted Katy to blindfold herself, send him her address, and sit in her bedroom and wait until he gets there and then she gives him a blowjob. Katy is so excited for this thrilling experience, and she hangs up with her friend to get ready… Katy walks to the bed in her blindfold, where you are laying down already… She still has no idea that it’s her brother laying there, and not the hot guy at school that she likes. Katy crawls over to your cock, and lays down and starts to suck your cock. “I’m so excited… I’ve been waiting on this for a long time.” Katy sucks your cock, taking all of it down her throat. “This is really exciting, I’ve never done anything like this before.” Katy licks up and down your cock, and starts to deep throat you. You grab your sister’s head and push it down on your cock. Katy licks and sucks your cock until you cum all over her face. “You came all over me! Does that mean I get to take this off now?” Katy rips off her blindfold, with mascara running down her face…. She immediately twists up her face and screams, “What the FUCK!?” Katy screams at you, asking what you’re doing and where her crush is. You tell Katy that you made the account, and she continues to scream at you. “You’re sick as fuck, I’m your sister!” Katy tells you that she’s going to need therapy… and starts to cry. “I thought I was getting to blow the guy of my dreams!” She flips you off, and storms out of the room.
