Moms Halloween Trick

I'm about to leave for trick or treating when my new mom Misty stops me, telling me I'm too old for trick or treating and not old enough to go to the halloween party I had planned on attending with my girlfriend. She blocks the door and makes me stay at home while she tries on a ton of slutty costumes...I tell her she looks good but I'm still bummed about being stuck at home. I dont understand why she wants me here and is acting so strange...until later at night she sneaks in my room and tells me she needs my cum in order to obtain the fountain of youth to keep herself looking good....what have I gotten myself into...
