I’m your fiancé’s bratty/slutty twin step-sister trying to get back at her for stealing my boyfriend years ago. But I decided go a step further by tricking you into having sex with me (you thinking I'm your fiancé).
I slowly wake you up with me straddling over you dressed in red lingerie/high heels. I start talking to you straight away saying I've got home early from my work conference and thought I would surprise you by waking you up like this. You say I look amazing and are also surprised that I'm dressed like this. Plus we’re weren’t supposed to be having any sex yet as we wanted to save it for when we got married in couple of weeks.
I start smiling mischievously saying that I’ve changed my mind. Saying that we should not wait anymore and I want to do it now. You are hesitant because you're not so sure & we’ve waited this long, so we should hold off.
I don’t agree and slowly start to seduce you playing with my tits & slowly grinding on you, talking dirty at the same time. Again quite out of character. You actually make the comment “you sound like your step-sister” which I repeat back to you and start to laugh, saying what’s wrong with that.
As I start to pull out your cock, again you try and resist, but I keep on saying it will be fine, We will love it, I start kissing you and whispering "don’t you want to fuck me?” I take your cock into my mouth and keep talking naughty as I blow you. You wonder what’s gotten into me but I keep brushing you off. I get on top and slowly brush the tip of your cock against my clit as if i’m going to put it in my without a condom. You stop me and say that we are DEFINETLY not doing with without a condom at least.
At this point I reluctantly get a condom out and say it’s fine, we will use protection. But as I slowly unwrap it, I start to kiss you and distract you so that I only pretend to put the condom on. I toss it to the side and straddle you without you noticing.
We then start fucking and I start making comments on how great this is and I then say I knew I would be better than my step-sister, which you question, but I just say, Don’t you agree?” You say yes, not realising that you're fucking the wrong step-sister.
I then start to put words in your mouth, saying “isn’t my body sexier than normal”, “I have better tits than my step-sister”, “I look sexier”, “I’m more slutty”, which you agree with of course.
As you are getting close to cuming I start revealing things... like first of all how I didn’t put on the condom, but it’s all ok and I’ll get off when you're about to cum. I just keeping kissing you and grinding on me. You're a little concerned, but keep on going.
Then as you're about to cum, you ask me to get off, but I look at you and say no, "I want your sperm in me as this won’t count without it, I want you to shoot it up into me."
As you sort of struggle you then cum and I look very pleased/aroused that I have your sperm. I then sort of change back into my bratty/slutty self and tell you, “not to worry, step-brother-in-law.”
You're all worried/concerned but I just laugh and slowly get off you saying how ridiculous of you to think I was actually my boring, prudish step-sister. I tell you how pathetic she is and how much better I am. She’s woorthless and honeslty I made you cum harder than you ever have. Also, here’s the big kicker, I lean over and grab my phone to reveal that I recoreded our entire fuck! My step-sister is surely going to love her wedding gift: our sex tape... enjoy me, xo HOMEWRECKING/CHEATING/STEP-SISTER IN LAW/STEP-BROTHER IN LAW/TWINS/LINGERIE/POV SEX/DILDO SUCKING/CONDOM/IMPREGNATION FANTASY/IMPLIED CREAMPIE/FEMDOM/DIRTY TALK
