Pranking My Stepsister Kitty By Turning Off The Power To Fuck Her with Creampie

I had enough of my sister, Kitty, walking around the house naked. I could not take it anymore, I really need to fuck my sister. I go down in the basement to the breaker box, I turn off the power to the bathroom knowing Kitty would call for my help. As planned she yelled for me to come help, this time I am gonna more then help my sister. She takes off her towel and I show her my big cock, she drops to her knees and starts to blow my huge cock. I can not believe what's happening but I keep my cool and fuck my sister's tight pussy till I just fill her up with my cum....
