-Backstory-

Ever since her husband died, they've relied upon each other emotionally and physically.
However, her step-son had recently fallen for a girl (who _ Vanessa believed was a gold digging slut) and eloped in Vegas.
Thankfully to a technicality (their Elvis impersonating priest's fucked up on their marriage license), step-mom convinced her step-son to get a prenupt before the official marriage.

-Backstory-
Vanessa and her step-son have always been close.
Ever since her husband died, they've relied upon each other emotionally and physically.
However, her step-son had recently fallen for a girl (who _ Vanessa believed was a gold digging slut) and eloped in Vegas.
Thankfully to a technicality (their Elvis impersonating priest's fucked up on their marriage license), step-mom convinced her step-son to get a prenupt before the official marriage.
Feeling guilty the step-son agreed to it, but kept the details to himself.
During the morning, Vanessa came over to her step-son's house to drop off a couple things for their family dinner that night.
She heard noise come from the backyard, so she checked it out, and it was just her step-daughter-in-law on the phone.
She was about to leave when she overheard something about the prenupt.
She heard her step-daughter-in-law tell whoever was on the other end that "as soon as I get pregnant, with his, the prenupt is useless..."
She thought it was suspicious but didn't want to confront her step-daughter-in-law, since she would most likely deny any such scheming, and use that to further antagonize her and draw her step-son away.
Her step-daughter-in-law then called Vanessa 's step-son and reminded him they'll be starting tonight.
As Vanessa was quietly leaving she stumbled upon her step-daughter-in-law's agenda/schedule book on the kitchen table.
Due to her step-son's busy work schedule, it was stated that ever week on this day, they were going to try and conceive.
Another thing she realized was her step-daughter-in-law's daily multi-vitamin pills on the table looked quite a bit like the birth control pills she used to take before her step-son got married.
With those two things in mind, she thought up a way to stop her step-daughter-in-law's schemes.

Scene 1 - After the family dinner

After Dinner Vanessa is sitting with her step-son, talking.
Her step-daughter-in-law is in the kitchen finishing up on the dishes.
During the conversation, Vanessa nonchalantly asks him, "so are you two trying to get pregnant?"
Her step-son looks at her in surprise, "Who told you?"
"Oh, no one, lets say a little bird told me" replies mum, jokingly. "So are you trying?"
"Well matter of fact, we start trying tonight mum" replies her step-son.
"You know, all this talk about baby making is making me hot" states mum.
She grabs her step-son's crotch and rubs it.
"Um, mum..." says the step-son as he nudges his head towards the kitchen.
Vanessa unzips and takes her step-son's cock out, and shouts towards the kitchen "Do you need help with the dishes?"
The step-daughter-in-law shouts back saying that she's alright and should be done in about 10 minutes.
"See, we have time" Vanessa says to her step-son.
"Mum, I don't want to cheat on her" says the step-son
"Just a BJ then, that isn't cheating is it?" asks mum as she undresses partially to expose her tits.
The step-son is too turned on by this and just stays quiet.
She drops down to her knees and starts sucking her step-son's cock.
She vigorously sucks her step-son's cock, dirty talking to him in between sucks, such as telling him how much she loves sucking her step-son's cock.
She begs him to give her mouth his sweet cum, and he explodes in her mouth.
She shows her step-son what his done and swallows it to leave no trace of what happened.
She then tells her step-son to get cleaned up, and he leaves.
After he leaves, she takes out a pill bottle containing birth control pills, and swaps the content with her step-daughter-in-law's vitamin pills.
