My brother is blackmailng me!?

So, I got a new justin beiber doll, and the first thing I did with it was shove it between my **** and squeeze them together. Then I sucked on it a bit, and shoved it between my *** cheeks and squeezed them together. After that, I started to rubs my clit with it, pretending it was really him, then I stuck it in me and came. Right when I came, my brothers friends came out of my closet laughing with their cell phones out, taking pictures! They witnessed he whole thing and put it on facebook! And my brother threatened to put it on YouTube tomorrow unless I give his friend a ********! What do I do!?!? Please please help! :(
