Something else

John used the App on Brianna. Brianna is immune to all sexually transmitted diseases. Brianna cannot get pregna. Brianna craves sex. Every day, Brianna craves a cock in her mouth, her pussy, and her ass. She has no idea why she craves it, but she must get a cock in her mouth, another in her pussy, and another in her anus every day, and it cannot be the same guy more than once a day. This makes her feel like a total slut, but she cannot help herself. She orgasms easily and often during sex, and her pussy and anus are always tight and virginal.

John gave a loud, exxagerated evil laugh.

1) Go check on Brianna

3) Invite some friends over to take advantage of his new slutty step-sister
