Jason is having a bit of a problem with his private parts. He's embarrassed, but eventually his stepmom, Fiona Moore, figures out that there's an issue. She talks to Jason about it, and though he's embarrassed, Fiona points out that she's a nurse. Of course she can help him. When Jason reluctantly lets Fiona get a look at his stiffie, she is quick to wrap her hand around him and start stroking. Then, reassuring Jason that mama's going to make it all better, Fiona starts sucking him off.
When his bigtit stepmommy pops those boobs out of her shirt and uses them to deliver a titty fuck, Jason can barely believe his good luck. Things just keep getting better for him when Fiona decides that it is, of course, medically necessary to peel off her pants and slide down onto Jason's fuck stick. He gets to watch that big booty bouncing as Fiona fucks him on the couch. When Jason and Fiona relocate to the bedroom, she resumes her stiffie ride with total enthusiasm.
Turning around, Fiona keeps on riding the D in cowgirl as she rubs her own clit. That position lets Jason admire those big jugs as they bounce with every thrust of Fiona's hips. Then Fiona decides it's medically necessary to get on her hands and knees so Jason can bang her from behind. Her diagnosis continues as she rolls onto her back and lets Jason go to town on her bald fuck hole. When Jason is finally ready to cum, his stepmom is there waiting to take his hot load on her stomach. As she enjoys the aftermath of a lusty romp, Fiona pronounces Jason cured.
