My brother George enters the bathroom while I'm in a towel getting ready. I'm a little embarrassed because my towel won't stay up, and I don't want him to see me naked. He says he's hiding from mom and dad though, so I let him stay while I get ready. When I'm getting ready though, I notice him staring at me, and then see his huge boner in his pants!! Why do you have a boner while looking at your sister?? He says he has to get rid of the boner before he goes out, and asks me to help. I don't want to, but I do want him to get out. My towel falls off, and I give in. I go down to my knees and start to jerk him off. I spit on his cock, stroke it, and even suck it and lick it. I dirty talk him while I touch him and try to get him off. I rub his cock against my tits, and titty fuck it too. Then I hear mom in the hall way and tell him that he needs to hurry up and get off! I dirty talk about him fucking my pink wet pussy and finally that does the trick. I beg for him to cum on my tits and he does. Guess I need to shower again!
