Blackmailing My Sister Kimmy

I found out my sister Kimmy has been cheating on my good buddy! So, I did what any single guy would do...I blackmailed her fine little ass for a blowjob! Hey, it's not my fault she cheated on her man and got caught; I'm not a bad guy. After a nice cock sucking, I blew my fat load on her face and got out of there.
