You come home early and stumble upon your Step-Mom & Step-Aunt making out, wearing lingerie & handcuffed to each other in the kitchen. You quietly unzip your pants and begin to jerk your dick to them while they get freaky. You imagine that they invite you to join them even imagine them moaning your name while they rub their asses all over you. The sounds of their yells snaps you back to reality. Step-Mom & Step-Aunt know that you have been watching them and try to get away.
You think fast and throw away the handcuff key leaving them at your mercy.
