Your sister has always been, well, fragile. But since we moved to a new town, she’s really had a hard time. It seems like you’re the only one that she listens to and connects with. As your mother I think that, maybe, you two should start dating. No one has to know that you’re really siblings. I love you both so much, and I’d love to be involved, too. Thinking about my son and daughter having sex gets me so excited that I start playing with myself on your sister’s bed, with her sex toy. I come hard as I tell you all the dirty things that I want us to do together. I want to make you fuck her with my cum on your dick, make you lick me out then kiss her full lips, have you both sucking on my tits at the same time—I go on and on. You’re so lucky to have such an open-minded slut for a mom
