I walk into my room, not noticing you in the closet having a quick jerk. I push open the door and am taken back by you, my little step-brother naked jerking your dick. I laugh and you begin to cry. You explain to me that you have been curious about the female body, so being the nice older step-sister that I am, I am going to give you lots to jerk off too little step-brother. Im going to make you cum a huge wad for me!
