step-Mom and step-dad are away and we're supposed to be cleaning the house. You ask me to hand you your game controller instead. So I suggest we play one of our step-brother step-sister bonding games that we love so much, instead. It's hot so I take my sweats off and start cleaning in my panties. The games we decide to play is called The Electrocution Game. The rules are you hold you dick in your hand and don't move unless I call out electrocution. If you cum before I let you, you lose. If you last long enough you get to pick where you "finish the storm." I keep making excuses to change my panties while randomly electrocuting you. Finally, I let you pick where to finish. I get horny and make my pussy cum before shaking my ass in your face until you nut all over my ass.
