My step sister thinks she is so smart, but today a letter came from school today. It's for Kira's mom, it says that Kira is failing 2 of her classes! Kira knows she will get in a lot of trouble, and probably get the car taken away from her. She begs me not to tell, I am not gonna lie my sister is kinda hot. Time to time i'll watch her take a shower and jack off on to her panties. I advice Kira that if she wants me to keep my mouth shut she will have to watch me jerk off.. her reply is I am gross and perverted but it's the only way to keep my mouth shut. I make my step sister show me her tits, spread her legs, suck my cock, and take my huge cock in her tight pussy! Kira tries to run away from my huge dick but I pound her pussy till I fill it up with my cum! Kira freaks out and kicks me out the room as the cum flows out of her pussy!
