She's not actually blind
Tara Ashley and her stepbrother Justin Hunt have a strained relationship. As they watch television together they argue over the remote wile Justin sneaks touches to Tara's boobs. Later, while Justin is passing by Tara's room, he spies his stepsister naked on the bed and hears her talking. Her words are for her boyfriend, but Justin mistakes them for him, so he does as Tara suggests and sneaks into her room where he finds his stepsister wearing dark glasses and wrapped up like a Valentine's Day gift. Since Tara's glasses are blacked out she has no idea that it's her stepbrother instead of her boyfriend when Justin settles between her thighs to lap at her bare pussy. Soon her super skinny hips strain towards Justin's mouth so he can make magic with his tongue. He replaces his mouth with his big dick, pounding Tara's creamy fuck hole as she fills the room with her moans. Taking the time to stroke and suck Justin's hardon, Tara works her way on top of him so she can slide down on his fuck stick and give him an enthusiastic ride. When she turns around for a reverse cowgirl fuck fest, Justin can only hang on so long before her adjusts her so he's on his knees matching her stroke for stroke. Tara's orgasmic cries are a musical accompaniment to Justin's last few thrusts before he explodes with a creampie of cum for his stepsister. Only then does Tara take off her glasses and see that it's her stepbrother instead of her boyfriend pleasuring her cream filled twat.
