A Brother's Betrayal (Patreon)

"I'm sorry, Alan. I used to be your brother before I met my Sissy Queen. She has made me such a needy slut. When I told her I had a brother, she said she just had to meet you. Don't worry, it doesn't hurt. It feels so good. And soon we'll be sisters. And you'll worship Her on your knees with me. Just wait until you learn how good it feels to suck cock as a sissy sub."
