-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.
After a couple months of trying, the step-son and his wife are still not pregnant (thanks to Vanessa switching her multi-vitamins with birth control constantly)
The step-son's even more stressed out because his wife seems to be exceptionally bitchy these days (also thanks to Vanessa switching her multi-vitamins with birth control)
His wife isn't "feeling well" again... so he goes grocery shopping instead.
He gets whatever his wife wrote out, including her daily multi-vitamins, which is about to run out.
On his way back, he feels home sick and longs for an actual home-cooked meal; it's been almost a month of take out.
He heads over to his step-mom's house.
His step-mom is happy to see him and she fixes him up some dinner.
After dinner he tells her how agitating it's been.
He ends up doing all the house work / chores these days, "...like buying her damn multi-vitamins... doing the laundry..."
It also doesn't help matters that sex has become some kind of mundane chore as she just lies there until he cums in her, weekly.
Vanessa realizes that this is a great chance to switch out the pills, in addition to helping her step-son relieve some stress.
She starts undressing, and his step-son diverts his eyes and says, "Step-Mom, I can't cheat on my wife... especially now... that we are trying and all..."
"It's just a BJ, and from your step-mom at that. Don't worry, I won't ask you to take it any further" says step-mom
She kneels and starts sucking her step-son's cock.
The step-son initially diverts his eyes and tries to be indifferent, but he can't help himself.
He soon starts groping mum's tits as she sucks his cock.
Mum dirty talks to him in between sucks and tells him to cum in her mouth so she can swallow his load.
He cums in her mouth, she shows it to him and swallows.
The step-son then tells mum, "Step-Mom, I'm still hard. Do you mind?"
"Of course not, honey" replies step-mom and goes right back to suck her step-son's cock.
For the last couple weeks, Vanessa has been giving her step-son bjs every time they met up.
They both have come to enjoy their "step-mom & step-son" time more and more.
However, the step-daughter-in-law has become suspicious of the constant visits to and from step-mom.
So step-mom and step-son decide that they should have their meetings in a more secretive fashion.
Step-Son is in the office working on his desk.
To his surprise, step-mom comes in quietly.
"Step-Mom, does she know you're here?" asks the step-son, referring to his wife who's outside in the waiting area/living room.
"No she doesn't" says Vanessa
She comes around the desk/table and says "scoot back"
Step-Mom stands in between her step-son and the desk/table, takes his cock out for him while takes off her clothes, and the step-son fondles her in process.
When she's almost done taking off her clothes, we hear the step-daughter-in-law in the hallway "Hey, honey, how much longer do you need?"
Step-Mom quickly ducks under so the desk/table is in the way and she can't be seen.
The step-daughter-in-law enters the room.
"You know we have that appointment to get to..." says the step-daughter-in-law in an agitated tone.
"Um, let me see..." replies the step-son
He looks down in surprise as step-mom disregards the presence of her conniving step-daughter-in-law, and starts sucking his cock.
While still looking down at his step-mom who is looking right as him as she sucks his cock, he replies "I have to go over the PO and some of the logistics, so can't really say..."
During the conversation step-mom continues to suck her step-son's cock.
The step-daughter-in-law sits down in the office and goes over things on her phone, while the step-son watches his step-mom suck his cock.
Step-Mom silently mouths words like "I love this cock"
The step-daughter-in-law gets up in frustration and asks again, "Just give me a rough estimate, when are you going to be done?"
Step-Son acts like his looking over work related content and replies "Let's see... hmmm maybe a minute or two?..."
At that instant mum looks up at him disapprovingly and bites his cock.
"Ooooooow... um.... better make that around 5 minutes for good measure" replies the step-son.
The step-daughter-in-law makes a frustrated groan and replies "alright" and walks out back into the hallway.
Step-Mom continues to suck his cock, talking to him in between sucks.
He then blows his load and step-mom continues to sucks his cock clean, knowing that if he can't just zipup and head out with his wife, she'd expect something... that paranoid bitch...
