[Fu4M] Your new stepsister is a ridiculously hung, tall, gentle Dommy Mommy
You and your father have been by yourselves for a while now, since things haven’t really worked out with your mother. Truth be told, both your father and yourself were pretty typical beta males; Not very tall, not particularly built or strong. And especially ever since he became single, your father has been struggling to provide for the two of you as well. Thankfully though, once he gets back into the dating scene, he comes home with the news of having found a perfect new partner. He says that he has been talking with this woman for a while, and that things really click well between them. So they have already decided to get married. Clearly, this comes as a big shock to you with how sudden it all develops.
At first, you’re not sure if you really approve of it all. But soon, you realize why your father is so sure of his decision, and how this new marriage can actually be a good thing. His new wife is a very successful, assertive woman who doesn’t take bullshit, yet is a very caring individual towards you and your father at the same time. But the best part out of everything? Turns out, she has a daughter too, which means that you will be getting a stepsister; Me! And once the two of us meet, your mind is nearly blown at what you’re seeing. I’m a much taller than you (and your father) girl, a gorgeous one at that. I have a huge pair of full tits that you can’t seem to take your eyes off of. And even though you don’t know it yet, I have a massive cock under my clothes as well.
With how shy you naturally are, you haven’t really talked to me at all ever since we’ve moved in together. I am pretty laid back and confident, yet you seem to avoid me at all cost. Probably because you feel intimidated, but also because you very undeniably can’t deny how attracted you are to your new stepsister. You can’t help but steal glances at her amazing physique. And you think that you’re being subtle, but I’ve been noticing your looks from the beginning. Lucky for you, I was actually pretty fond of eager little boys like you too…
Just barely a week later, our parents decide to go on a camping trip to get to know each other better and hopefully have you move a little out of your shell. You’re not comfortable with the idea, but don’t really have a choice. Just when you thought things couldn’t get worse, once we get to the camping site and are unpacking, we find out that your tent has been torn somehow. With no stores to get a new tent anywhere close, we decide that the best possible option is that you and I will be sharing my tent for the trip. Surely you and I well manage to create a bond in there, don’t you think lil’ bro?
