I get a text from my boyfriend requesting nudes. I smile and gladly send them to him. Afterwards my step brother barges into my room and tells me that he pranked me and I actually sent the photos to him instead. I am shocked and angry with him and tells him to delete them immediately. He refuses and blackmails me to do sexual favors with him in order for him to keep this a secret. I first say no, but he turns to walk away and tell on me and I give in. I suck his cock, ride him, and get fucked. I tell him not to cum in me and he doesn't listen and cums in me anyway. I tell him that I didn't take my birth control, and therefore risk getting impregnated
