Live out your secret naughty fantasies at this Halloween swingers party, courtesy of Mass Pleasures, the "World’s Premier Luxury Pleasure Club." RSVP for an invite to a secret LA mansion at this classiest of sex soirees, touted as a "unique playground for the world's sexual elite." Mingle with pretty professionals indulging their hedonistic desires. Dress (and undress) to impress, and be prepared to lose your mask, if you so choose, at midnight during this Fantasy Ball. In a not-so-subtle move, "hot single ladies under 35" can email the company to request a ticket, while couples have to shell out $150 for a BYOB pass.
