As Kylie Quinn is doing her laundry, she discovers that her panties are covered in cum. She's disgusted, but also intrigued. She goes to her room and leaves a trap for her stepbrother Juan Loco where she has a whole laundry basket full of panties. After taking her own thong off, Kylie hides in her closet and watches.

Once Kylie has confronted Juan, she relents. She tells him that she'll watch him jack off into her underwear if it turns him on. The minute Juan's dick comes out, Kylie wants it. She comes in to stroke and suck him off. Then she lays down and parts her thighs so Juan can dive deep for a pussy feast.

Since Kylie is already splayed out for him, Juan has no trouble getting to his knees and shoving himself into her twat. They spoon together next as they keep on fucking. Then Kylie gets Juan on his back to ride him in cowgirl. Once he's dicked Kylie down on her knees, Juan gets to cum on her face. The stepsiblings are just basking in the afterglow when their parents walk in on them.
