Thank you for getting here so fast, step-bro. I knew I could depend on you just like I've always been able to depend on you.

This problem I'm facing, well, you're the only person I can trust to really help me out with it. I really don't even know how to explain what I'm going through. You see, there's this secret that I've been keeping from you for a very long time. I didn't want to keep it from you, but I was also worried that you would judge me, and I couldn't bear the thought of you thinking bad about me or treating me any different.

But I guess it's time for me to tell you what my secret is. Or better yet, I should just show you...

This is it. This is my secret. My very big secret. I have a d*ck. A big, throbbing hard girlcock. And the fact that it is so achingly hard is my problem. I've been rock hard for two whole days now. I've c*m so many times I've lost count. My girlcock is sore from j*rking it so much. Yet, no matter how much I j*rk off and no matter how much I c*m my d*ck stays hard. It's aching so bad and I just want to no longer be hard! What can I do?!

You think that if someone else helps me c*m that it will go away? Well, who can I get to help me out? I've never actually been with anyone else before....

You want to help me out with this problem?! I would love that! I've actually had a crush on you for a long time now. I guess the first thing you can try doing is sucking my girlcock. Maybe having your mouth around my d*ck and making me c*m like that well drain my b*lls dry.

L*ck my c*ck from the tip to the base, massage and play with my b*lls, make me c*m, step-bro....

I'm getting so close, can I c*m in your mouth? You would like that? Yes, take all of my c*m...

Hm, it seems like my b*lls are still filled with c*m, maybe you should keep on sucking my girlcock. Keep on milking all the c*m out of me. Deepthroat my c*ck this time, maybe that will be what finally drains me.

Omg, I came again and my c*ck is STILL hard. Just keep on sucking it. You're so good at it and I think that if I c*m on your face next time and absolutely drench you in my c*m that will finally do the trick. The image of you absolutely coated in my c*m will be so amazingly hot...

Wow. Well, you do look absolutely fantastic covered in my c*m, step-bro. I can't believe that I am still so hard, though. We're going to have to try something else. You've been such an amazing step-brother and so worried about my c*ck that you haven't even been focusing on your own hard c*ck. So, I have a great idea. You love my c*ck so much inside your mouth, so I'm sure you will also love it in your *ss! And while I'm f*cking you in the *ss, I'm going to stroke your c*ck. I want you to feel pleasure just like you've been giving me pleasure. I want you to c*m all over yourself as I fill up your *ss with my c*m...

Now your stomach is filled up with your step-sister's c*m, your *ss is filled up with your step-sister's c*m and your face is drenched in your step-sister's c*m. BUT I AM STILL SO HARD. But f*cking you like that gave me yet another idea. I want for you to f*ck me in the *ss this time. After all, your d*ck is still hard. Let's see if having my step-brother's c*ck in my *ss as I j*rk my girlcock is what will finally make this aching erection go away and for my b*lls to finally be c*mpletely drained.
