Your mother has dressed as the same thing every year, for trick or treating: a witch! Its cutsy, fun, but this year she decides to spice things up, and goes into town to one of Salem's many oddity shops, to find a new accoutrement. And find she does! An enchanted--no, cursed--necklace, harboring the spirit of a sex-crazed, taboo succubus hellbent on making the world her mother-son cum-filled playground!
Of course, this is also the year you and your friends decide to have a bet: who can get the most candy. Your mother thinks its a silly thing, but when you knock at your own door, costumed and--most importantly--masked, she seems to have a different feeling about this bet. In fact, she has a counter wager: whichever boy can give her the most cum will get an extra, bonus allotment of candy. Consolation prizes for the rest of you, of course.
You watch, transfixed, as your mother takes your friends cocks, stroking your cock under your mothers watchful gaze, as she dirty talks you...and...can she tell who you are? You're not sure at first but after she takes the first load, you know she does. And she loves it--loves teasing you, making you watch her take cock and cum while you stroke!
"I want all you boys to go home, go home and give your mothers cock and cum. Slip your young dicks between their lips," she purrs, stroking your edged, built up load all over her tits.
