Logan Long is excited to receive his x-ray glasses in the mail. He tries them out on his stepsister Alexa Grace, and is shocked to find that they work: He can see right through Alexa's clothes to her bare tits and panties. Once he realizes how cool the x-ray specs are, he keeps on creeping on Alexa so he can enjoy her sexy body and big ass. He quickly learns that Alexa often doesn't wear a bra, and occasionally goes commando besides.
Eventually Alexa gets sick of the creepy looks Logan is giving her and she steals the glasses from Logan. She puts them on and realizes that Logan is actually seeing her naked whenever he puts the glasses on. She gets an eyeful of his big dick, though, and can't get it out of her mind. Alexa agrees to Logan's suggestion that they can just fuck and no one needs to tell either parent. Soon she's on her knees with Logan's big dick buried in her mouth.
Falling onto her back on the couch, Alexa spreads her thighs so Logan can sink balls deep into her creamy bare pussy. Reaching down to rub her clit, Alexa brings herself to a big O as Logan pounds her fuck hole. Then she gets on her hands and knees to do it all over again in doggy style until the room is filled with the sound of her orgasmic groans. Moments later, Logan responds to Alexa's pleas to cum on her by pulling out and covering her ass in jizz.
