This is Alison and Zoeys first super slutty Halloween. They want to make it count, plus their parents are getting shwasted at some costume party. They invite a boy from school over to chill with them and get into some sexual Halloween shenanigans. Their stepbrother Rob did not only overhear their devious plans, but when the guy mentioned him they referred to Rob as a dweeb who is probably out trick or treating. It was time for Rob to not be a pussy and show his slutty sisters the dark side of his personality. He locked all the doors that were left open for the other kid, and found the spookiest mask he could. He entered his sisters room and pointed straight to his cock. The girls sucked his succulent serpent double time then took turns riding his face and cock. After jizzing all over their faces, he knew he had taught them to never underestimate him again. As the girls were winding down from their intense orgasms, they get a text from their original boy toy saying the doors were locked, and he figured their parents got home early, so he left. This left the girls feeling scared and used. Who was that masked man anyway? And why was his cock so familiarly yummy ;) ?
