OK, Bro, ever since I let you watch me blow my boyfriend, you've been acting differently. Before you were barely around, and now it seems that every time he comes over, you have no other plans. It's not really a problem, I just want to know, why? See, my boyfriend and I were talking about it, and he thinks it's because you have a crush on me, but I think, it's because you have a crush on him... Wait... omg... you have a crush on both of us don't you! Wow, you dirty little perv. I bet you've been thinking about that day a lot, haven't you? Well, bro, I have to admit, I've been thinking about it a lot too. And, actually, I talked to my boyfriend about it, and we agreed that we both want you back in the bedroom with us... not just to watch, but to participate. Now, I don't mean, like, you get to do whatever you want. I mean, you'll be more like, our cuckold! You don't know what that is? Look it up. Haha. Yes, we want you to serve us in the bedroom; to do the things to one of us that the other can't be doing... like, if my boyfriend and I are making out, you can be sucking his cock... but only if I command it. You will not do anything unless my boyfriend or I command it, and you will not even touch yourself until both of us have finished. Which brings me to an important part of your role: you will be consuming both of our cum every single time you're in the bedroom with us. Then, once you've done so, you will jerk off as quickly as you can while we humiliate you and make you eat your own cum and compare the tastes. Haha! Doesn't that sound wonderful? Great! Because, my boyfriend actually just left, and I have the condom we just used, filled with his cum and coated in mine. You're going to swallow and lick it all up, and then you're going to cum into your hand for your sister and eat it all up. And you know what, little bro? It might just turn me on so much that I'll text my boyfriend and tell him to come back right now to start our new life together... the three of us.
