Jack Off for a good cause

For the price of $25 you can get in the door and surround yourself with people doin' the 'freak nasty' with themselves.  The San Francisco Center for Sex and Culture hosts its annual Jack 'N' Jill off.  Masturbators can come together in a pansexual group setting and endure bold erotic adventures.  You bring the hard-on they provide the lube and toys.  This isn't like your normal orgy - rules do apply: 'Substance free and no penetration.'  You can get more details at www.sexandculture.org
