Bro! What are you doing in here?! I'm trying to make a bubble bath in peace, omg. I don't care if you have to go to the bathroom, just go outside or something. Ugh, fine. You can come in and go to the bathroom. Just be quick. I'm trying to relax, after all. ...Omg. I didn't know that you were so big, bro. Hey! You can't blame me for looking! I mean, your dick is just right there. What am I supposed to do? Not look? Besides, I'm your sister, so it's okay if I look. Here, look at me. Now we're even. Although, I do wonder what your dick would look like completely hard. Are you a shower AND a grower? We are home alone... maybe I can do something to get you hard so I can see what it looks like. Don't look at me like that! I know I'm your sister and you're my brother, but it will just be a blowjob. Okay? It's not like it's actual sex, so it's totally fine. Hehehe, well look at you. Just hearing me talk about sucking your dick has gotten you hard. You've probably never thought about your sister like this, but one of my favorite things to do is suck big, thick cock. Just like yours. I'm going to love sucking your dick. And when you cum, I want you to spray your load all over my pretty face.
