Step-Daddy's Obsessed With Me

I'm your step-daughter and I'm at your house with my husband and the rest of our family for a pool day. My step-mom pulled me aside earlier and told me that she found something awful on your phone... pics of my ass in my swimsuit!! I am super pissed and disgusted and I tell her I'm going to have a serious chat with you. I cant believe my step-dad was sneakily taking pervy pics of me!! You're in your room and I walk in wrapped in my towel. I greet you as I sit down on the bed and take my towel off. I immediately start rubbing oil on my arms and explain that I am just getting ready to go back out to the pool. I ask you if you would help me rub on my lower back. You agree but can't figure out why I'm acting so weird. I start to tease you about how you probably like rubbing oil on your step-daughter. You ask what I mean and I just brush it off and say I'm joking. It's clear I'm making sly comments but you don't know why. I start to rub oil all down the front of my body while I look you in the eye, you start to get really nervous because this is so hot but... why is she seemingly coming on to you?? Out of nowhere I get really pissed off and yell at you for having these gross pics of me on your phone. I call you a pervert and ask you why and how do you even have these pics?? Don't you realize I'm your STEP-DAUGHTER!? I tell you that I even found the fully nude ones in your hidden folder, those were for my husband...not my step-dad! Step-Mom didn't find those thankfully, but I am so mad at you! You tell me that you're sorry but step-Mom hasn't had sex with you for so long and that it's not your fault I'm so attractive. I start to soften a little bit through the conversation and ask you when this all started. I seem to like hearing all the compliments and I start to get more curious. I begin comparing myself to step-Mom and make you tell me what you like better about me than her. I start to actually feel bad for you in a weird way, I say that just to get it out of your system I will let you see me naked just this once. I slowly take off my swimsuit and show off a little for you. I keep asking if my ass, tits, and face are better than step-moms. Then I ask you if step-mom ever sucks your cock anymore. I make you tell me that you want your step-daughter to suck your cock. I give you head with lots of taboo dirty talk and comparing myself to step-Mom. Eventually I ask you if you would ever actually fuck your step-daughter... since you're so obsessed with her, would you actually stick your cock in her? I lay down in missionary and start rubbing my wet pussy over your cock. Step-Mom calls me to make sure everything is okay, I tell her that I'm in your room giving you a really serious talking to. She totally buys it! You fuck me in missionary and then doggy style until I beg you to cum inside of your step-daughters pussy. Then afterwards I take some nudes for you on your phone that you can save for later. I know I said just this once but... no one can compare to my step-Daddy. I need your cock again as soon as possible.
