Ryder almost finds him out, but Alex manages to hide the package. When it comes time for Alex to take on Ryder's challenge, he secretly puts the fake dick on and gives it a few strokes for show. He claims that he needs some help from his stepsister, so Ryder flashes her titties and even gets down in a crouch three feet away to receive Alex's cum shot. She finds herself unbelievably turned on, something she didn't expect from her stepbro. Peeling her shorts down, she gets into bed and wiggles her ass to invite him to fuck her in doggy. She is thrilled with what Alex has, from deep throating it to riding it in cowgirl and reverse cowgirl. That drives Ryder wild! She rolls onto her back and spre herself wide open for Alex to stick it in her and get her off one more time. Throwing her head back in pure bliss, Ryder rides out her orgasm and then watches with greedy eyes as Alex pulls out to cover her belly in a cum shot of his own.
