In this adult role-play, my childhood friend accidentally sends an explicit photo of herself to my phone, then desperately messages me to delete it. Turned on by a side of her she would never willingly show me, I jokingly reply that I will erase it if she has sex with me. To my surprise, she agrees but makes me promise to keep my word. We end up having sex, although I secretly plan to treasure the photo and keep using it as leverage for more free sex.
