It's the morning.
Step-Son walks into Step-Mom's room and check around to see if step-dad is gone. (no one in the bathroom or closet, and no car in the drive way)
He turns his attention to his napping Step-Mom.
He takes out his cock and starts rubbing it on his Step-Mom's face.
Then is slowly slides it in to her mouth and pushes it in and out.
Step-Mom gradual wakes up and smiles/giggles as the step-son is gently pushing his cock in and out of her mouth.
She starts actively sucking then, pauses for a moment and asks if step-dad has gone yet.
Step-Son state...

It's the morning.
Step-Son walks into Step-Mom's room and check around to see if step-dad is gone. (no one in the bathroom or closet, and no car in the drive way)
He turns his attention to his napping Step-Mom.
He takes out his cock and starts rubbing it on his Step-Mom's face.
Then is slowly slides it in to her mouth and pushes it in and out.
Step-Mom gradual wakes up and smiles/giggles as the step-son is gently pushing his cock in and out of her mouth.
She starts actively sucking then, pauses for a moment and asks if step-dad has gone yet.
Step-Son states that he checked to see if they're alone.
As usual she vigorously starts sucking his cock.
She then remembers and reminds him that they have an addition to the lesson from couple days ago.
She restates how much she loves the taste and feel of cum in her mouth and how she also loves to swallow.
Then she adds that there is one other thing she likes even more than that, and it's when some one cums inside her.
With that remark, she lies down and tells the step-son to take her pussy and make it his.
That comment arouses the step-son extremely and he starts fucking her with intent.
Mum dirty talks to him, while they switch to various positions.
She starts to beg for him to cum inside her and make that pussy his.
Step-Son cums inside her as they both enjoy an orgasm.
She gestures him to bring his cock towards her mouth, and she sucks him clean.
Now that his senses are back, step-son asks mum if she's on birth control.
She states that he doesn't need to worry, because mum and step-dad have actually been trying to get pregnant, and had no luck.
So either way, they're covered.
