Sister Mesmerized And Impregnated

My brother has been practicing mesmerizing me and having his way with me. He comes into my room one night and we have sex and he cums inside of me. He keeps coming back for more and then I get pregnant by him. I tell him I knew all along what he was doing and just pretending not to but that I really had cum super hard each time. Now that I am full of pregnant hormones I want even more.
