Jay Romero and his stepmother, Keira Croft, have a bit of a history. There was a point in the past where they got together, but neither of them came. It never happened again, so Keira prefers to not speak of it. Jay, on the other hand, is super into his mom and can't help but get hard whenever he endeavors to see her in any state of undress. When he spies Keira half-naked, Jay gets an instant boner and takes the chance to wander into her bedroom. Keira tries to tell him it's improper, but Jay refuses to be deterred even after Keira kicks him out.
When Keira is doing laundry, Jay tries again to get back in mama's pants. He waits until her skirt rides up and then pulls his hardon out. Approaching Keira from behind, Jay starts feeling her up through her panties. Keira is pissed and tries to get away, but Jay is still feeling saucy. He chases his mom around the house with his cock out until Keira storms away. Still later, Keira is in the shower when Jay sneaks in and starts jacking off to her naked wet body. Finally after a bit of arguing, Keira agrees to let Jay jerk it while looking at her. Watching her big dick stepson get himself off is too much for Keira to handle, though. She wants in on that action. She tells Jay that she'll make him cum and then keeps her word. They go on about their business even though Keira is still unsatisfied.
Since she didn't get off earlier, Keira is too horny to bear it any longer that night in bed. She's just getting into the swing of masturbating when Jay comes into her room, naked. Keira wasn't expecting that, but she ultimately agrees to let Jay lay next to her and masturbate, too. Their mutual masturbation quickly turns into Keira agreeing to let Jay eat her out. Once she has her son's tongue between her thighs, Keira knows that she's lost the willpower to keep saying no. Instead, she decides that they'll fuck it out in a variety of positions. On her back is good for Keira, but on her knees is even better. Riding Jay's cock is just what Keira needs to finally feel sated. She rewards Jay by blowing him until he cums in her mouth, leaving them both knowing that this is just the first of many sexual encounters.
