Demi Hawks needs to borrow her stepbrother Sage Roux's phone charger. When Sage declines, Demi offers to let Sage see and touch her tits. Saage is a little bit uncertain, but Demi gives him a show and then runs off when she yoinks the cord.

Later, Demi comes in and grabs a pair of Sage's boxers. Then she claims it's all wet and peels them off. When Sage complains that now Demi is going to get his bed wet, she offers to let him put his dick in her. It takes some incremental coaxing, but soon the stepsiblings are getting it on. It starts with Sage pushing in and just staying still while Demi moves to use him as her dildo, and then escalates from there.

Getting Sage on his back, Demi takes him by the root and leans in to suck. She goes on to mount him in reverse cowgirl, then turns around so Sage can thumb her nipples as she gives it to him in cowgirl. After enjoying Sage's big one in doggy, Demi rolls onto her back so she can cradle her stepbro between her thighs. She keeps him going as long as it takes, and when Sage is ready to pull out and nut he finds that Demi is wrapped too tightly around him to leave. He gives his stepsis a creampie she swears knocked her up.
