For some time now, my stepsister has been pushing me to have sex with her. I admit that I really enjoy fucking my stepsister, but she manipulates me and threatens to show pictures of us fucking to everyone if I don't fulfill her fantasy. Her fantasy is to have a threesome with her, me, and a friend of mine. So one day I called my best friend, Dany, and between the two of us, we fulfilled my horny manipulative stepsister's fantasy in Sharing My Stepsis With the Bestie.
