Emma Starletto wants her stepbrother's cock, and she'll stop at nothing to get it. She starts her quest to get into Seth Gamble's pants by wandering into his room wearing nothing at all but a t-shirt while chatting about fucking other boys. She waits until Seth reacts to her scanty attire, then whips off the covers so she can call him out on his boner. Later, Emma corners Seth in the bathroom while he's taking a shower. She claims she has to pee, but while she's on the toilet she starts talking about Seth's dad's dick. As Seth is left speechless over his stepsister's topic of conversation, Emma climbs into the shower and stars stroking him off. He finally snaps to his senses and beats it out of there.
Still later, Emma renews her determination to get her pussy pounded by putting on some yoga clothes and joining Seth in the living room, where he has already laid out a yoga mat for his own workout. She shoulders Seth out of the way and starts stretching right in front of him. She takes advantage of the position she's in by scooting backwards to rub her ass against Seth's crotch. When Emma tries the same trick she used earlier of calling him out on his hardon, Seth finally snaps. He whips it out while telling Emma that what's about to happen is her own fault. Rather than argue, Emma accidentally-on-purpose tears a hole in her yoga pants for Seth to give it to her without waiting another moment. Then she backs up to impale herself on Seth's fuck stick.
Moaning with delight as she finally gets the pussy pounding she's been craving, Emma rolls onto her back and spreads her legs to let Seth have full access to her snatch. Then she hops on top to ride Seth's man meat with fast and deep thrusts of her hips. Turning around, Emma continues her ride in reverse cowgirl. She winds up back on her hands and knees so Seth can truly do her in doggy, but when he tries to pull out to cum she shoves backwards to keep him inside. He gives up a creampie, glutting Emma with the cum she's been after from the beginning.
