Selina Imai loves Halloween. She's preparing by decorating the house, including a life-sized coffin. Her stepbrother, Sage Roux, asks Selina what she'll be for Halloween. She responds that she wants to get bred so she wants to wear an outfit that'll make that happen. Sage comments that if Selina's cute friend comes over and hides in the coffin, he'd breed the fuck out of her.
That's all Selina needs to hear to know what she has to do. After fantasizing about taking Sage's dick herself, she springs into action. Hiding in the coffin wearing a Halloween getup, Selina waits for Sage. He closes the door and reopens it, and Selina has lost some of her clothes. Every time Sage closes the door, Selina loses more clothes until she's naked. Going to the back of the coffin, Sage finds a glory hole that lets him fuck his stepsis from behind.
When Selina comes out of the coffin, she gets on her knees to suck her stepbro's hardon. Then she hops onto the counter so Sage can eat her pussy. Moving to the couch, Sage takes a seat so that Selina can ride him in cowgirl and then reverse cowgirl. When Sage gets Selina on her knees, she gleefully takes that pussy pounding. They wind up with Selina on her back and Sage dicking her down until he gives her the creampie that she hopes will breed her.
