Stepmom provides stepdaughter an education after comical misunderstanding

[Brandnewbuddy]

MC is married to her wife and their stepdaughter goes to an all girls boarding school but comes home on weekends and holidays.

So one Friday, Stepmom comes home early and stepdaughter is there, shooting daggers and packing her wife’s things. Stepmom asks what the hell is going on and stepdaughter tears into her.

“I SAW WHAT YOU WERE TEXTING MY MOM!!! How you think she’s a dirty whore, how you’re going to beat her ass raw, and take the strap to her. Is that what you do when I’m gone? Just beat her with a belt? Well we’re leaving and you can’t stop us!”

Stepdaughter then feebly starts beating her fists against her much larger, much more muscular stepmom who puts her over her shoulder with one arm and then calls her wife. To get home so they can both explain.

Stepdaughter eventually calms down enough to listen and they explain, even pulling out the strap-on. Stepdaughter is of course mortified and apologizes but stepmom can’t help but see an opening when she sees how stepdaughter keeps eyeing up the strap-on and offers to answer any questions she might have. After all, she’s grown and other girls at her school might be having sex.

What follows is some sincere lessons as well as stepmom seducing her stepdaughter (with mom’s consent). I figure mom would participate, providing some visual reference but would be reluctant to have sex with her daughter, though Stepmom would slowly convert her to the idea

(I figure the big scene would be stepdaughter wearing the strap on and both stepmom and mom are eagerly sucking on the shaft and balls and stepmom gets on all fours to take it but daughter instead grabs mom by the shoulders, having seen her mom be submissive for her stepmom, turns her around and fucks her while stepmom watches)

I figure for tone it would be similar to a silkstockingslover story with stepdaughter being seduced and stepmom and mom introducing her to a wider community of lesbian swingers (one joke I thought of was that mom sent her to the boarding school with the hope she would hook up with the girls there)

I will say though, even if it doesn’t go full incest, one scene I would like to have in there is one where stepdaughter asks how sex works with a strap-on and stepmom fucks her mom to demonstrate.

Daughter is actually pretty inquisitive during it, like asking why her mom is sucking on a fake cock and playing with balls of stepmom isn’t going to feel it and what stepmom gets out of it.

So at the end when mom is panting and has collapsed, stepmom gives her answer,

“Well this particular one does rub against me a little but you’re right, it’s not enough on its own to get me off. What get me off is two things: 1. The power from watching a grown rational woman descend into a wild animal is intoxicating.”

“So it’s just more power dynamics?” My stepdaughter asked, seemingly a bit disappointed.

I waved a hand dismissively, “hold on let me get to point two. Baby, why don’t you flip over and show us your face.”

With Herculean effort, my wife flipped over, revealing a face that was red from exertion and had hair stuck to it from sweat hitting her hair and pressing against the sheets, her eyes darted around, barely able to focus as the aftershocks of her orgasm rocked her. Her full lips parted in desperate gasps as drool pooled out of her mouth.

I ran my fingers over her cheek and smiled at her, grounding my beloved girl as she rode out the storm inside of her.

“2. When I’m done I get to see the face of my lover, a face I could only see with the help of this little handy tool. And that brings me a near orgasmic level of joy.”

I figure this could then be set up for the end where stepdaughter want to try the strap…ok stepmom, with her revealing she’s a bit of a too herself and stepmom is really a switch who hasn’t gotten to bottom in quite some time

Generally speaking, I love what you've written here! Very sexy.

(I figure the big scene would be stepdaughter wearing the strap on and both stepmom and mom are eagerly sucking on the shaft and balls and stepmom gets on all fours to take it but daughter instead grabs mom by the shoulders, having seen her mom be submissive for her stepmom, turns her around and fucks her while stepmom watches)

I would change that a little. After both moms suck on their daughter fake cock, stepmom lies down to be fucked as they as they agreed before. But the daughter gets a new idea.

"Mom, get on her. Pin her down for me. I'm gonna get really hard on her and I don't want her to escape."

Mom thinks it's really hot, so she jumps into it. The wives' bodies are perfectly aligned when Step-Mom takes the pounding. But then...

"OOOHH!" Mom suddenly yells when she's penetrated without the warning. But then the strap-on leaves her pussy and her wife starts moaning again.

"That's it, Moms! One pussy's not enough for me! I'm gonna fuck you both!" And then she proceed to do so, changing betwee then every few minutes for each of them to be properly fucked.

I figure for tone it would be similar to a silkstockingslover story with stepdaughter being seduced and stepmom and mom introducing her to a wider community of lesbian swingers (one joke I thought of was that mom sent her to the boarding school with the hope she would hook up with the girls there)

I don't like it, to be honest. I know that kinkflation is strong, but not everything needs to be about a society of fuckers - somehow a simple threesome incest story is enough.

The setup is hilarious and I love it. I think I'd try and avoid the direct incest angle though of the daughter straight up fucking the mother or vice versa. I also agree that the "wider swinging community" angle isn't necessary and would likely reduce from the intimacy of the three women's relationship.

I also think it could be that the lessons the stepmother initially gives are innocent enough, though the daughter realises that the stepmother is "accidentally" leaving the door open when she fucks her wife with the strapon, as well as getting more flirty and touchy feely with the daughter. I would keep the mother knowing what's going on as well.

But there's no direct incest! There is a strap-on between them, they don't touch! Or at least it's what they say.

Thanks for the advice! Okay, I’ll keep it small scale and downplay the blood related incest. I do think stepdaughter might watch them have sex or maybe mom holds her hand the first time stepmom eats her daughter out but the big focus would be on the stepmom and daughter.

I do think I’ll go with a first person POV with stepmom, with her being more than a little sleazy but not outright malevolent.

Like until she realizes stepdaughter is interested and more than a little turned on by what’s being discussed, she doesn’t see her with any sexual desire…once she does though…

“And as I saw those intrusive thoughts flicker through her eyes, those thoughts of ‘wait, what if that were me?…would I like getting fucked with a strap-on? Would I like it if it was my stepmom fucking me?’ I felt a transformation occur in my own mind. My adorable stepdaughter who I loved dearly when she wasn’t jumping to conclusions suddenly wasn’t just adorable. Suddenly as I saw her wrestling with thoughts of sapphic and taboo delights, my own mind started to churn out thoughts that were intrusive yet increasingly welcome.

In my mind I saw my stepdaughter strip out of her school uniform down to the Victoria Secret underwear which her little sheltered mind had thought was the height of lingerie. I remembered when she had bought it and me and her mother had feigned like it truly was an act of rebellion and not rather vanilla. But now I was no longer seeing a little girl but rather a young woman who had been developing a very nice bubble butt and had a pair of breasts which were destined to one day be just as big as her mother’s. As I thought that, I wondered if her nipples would be the same shade as my wife’s and the stepdaughter in my mind’s eye shed her bra to reveal that yes, she had rosy pink areola with hard nipples that were begging to be sucked.

“Oh god…” I thought, my tongue reflexively licking my lips, “I want to-no, I’m going to fuck my stepdaughter”


But even then she doesn’t creep on her, she just steers her and her mom into trying the idea out.

maybe mom holds her hand the first time stepmom eats her daughter out but the big focus would be on the stepmom and daughter.

I would change it into one of the following: either Mom half-lays down and Daugher leans into her (back-to-chest), or Mom sits down with Daughter's head on her lap. In such position, Mom can caress her head, wipe wet hair from her eyes, and whisper that she's a good girl. She can also keep encouraging her to hold longer, as the longer she restists, the bigger her orgasm would be.

I do think I’ll go with a first person POV with stepmom, with her being more than a little sleazy but not outright malevolent.

Why not a lovable stepmother who is rough in a bed only?

rather a young woman who had been developing a very nice bubble butt and had a pair of breasts which were destined to one day be just as big as her mother’s

Please stop describing 18+ years old as 15+ years old.

 

[Brandnewbuddy]

I figured she’s still growing at 18, lord knows people change throughout their life but I do see your point and yes, that would not be finalized dialogue

 

[GlennJenko]

I think the line works if it's even changed from "had been developing" to "had developed" and then the pair of breasts that had "begun to rival her mother's in size" or something to that effect.
