Megan Marx spies her stepbro Nick Stokes coming home from school. She tells him happy hump day and gives him a hug, leaving Nick confused. Later, Megan tells Nick happy hump day yet again and shares that she heard his girlfriend talking about how big his dick is. It may not be Wednesday, but it's the day Megan has decided to hump him. They're interrupted by Megan's mom arriving home.

Megan hasn't given up on hump day. She waits a few days and then tries again. This time she gets Nick's hand down her shorts to feel how wet she is. Megan can feel how hard Nick is, too, and she wants to suck him off. Fortunately, it's hump day so she can blow Nick as long as her heart desires.

Straddling Nick's hips makes it simple for Megan to slide down and ride her big dick stepbrother in cowgirl. She turns around for reverse cowgirl and then drops to her knees for doggy. Megan finishes off on her back with her thighs spread for Nick to dive nice and deep. He pulls out and covers Megan in cum just as Megan's mom comes home.
