LOS ANGELES – (May 16, 2008) – "Chemistry, Volume 4: The Orgy Edition," the latest movie from Vivid Entertainment's multi-award-winning director Tristan Taormino, will ship on May 21 and be in stores on May 28. The unique erotic experiment series was launched with "Chemistry" in 2006 and quickly garnered six top awards.

"Chemistry, Volume 4: The Orgy Edition" follows the same basic premise as each previous volume in the series: no script, no schedule and no rules. The hottest volume to date, all the sexual hook-ups are spontaneous and completely up to the performers. The cast includes Penny Flame, Adrianna Nicole, Sinnamon Love, Evan Stone, Tyler Knight and newcomer Johnny Sins, with special appearance by Tantra teachers and authors Mark Michaels and Patricia Johnson.

"Each time I shoot a volume of Chemistry, I think, 'It can't possibly get any better,' and then it does! I call this one "The Orgy Edition" because it's full of threesomes, foursomes, and moresomes," exclaims Taormino. "To say that this group clicked is a huge understatement: they couldn't stop having sex!"

Viewers see what happens when Sinnamon indulges her insatiable appetite; when Tyler is left alone with all three women; when Johnny arrives late – and must make up for lost time and much more. Sex begins as a one-on-one affair until whoever has the "Perv Cam" joins in the fun.

"We shot a lot of fun stuff in Chemistry 4: foot jobs and foot fucking, a Tantric Sex class led by award-winning Tantra teachers, Adrianna Nicole's signature oral sex position she calls 'Danish Suicide,' Penny Flame's very first scene with newcomer Johnny Sins, and a staggering amount of group sex," said Taormino. "Plus wait until you see what happened when Evan Stone put on his tiger suit!"

Shot in high-definition, the two-disc set features four hours of scorching sex in a non-stop orgy as the all-new cast of six adults are brought together for 36 hours to live out their fantasies.

"Tristan has outdone herself once again! This cast in particular is just really hot and it's so clear how much fun they were having," according to David Peskin, National Sales Manager for Vivid. "They let their guards down in their uninhibited sex scenes and they really bare it all in the confessionals, too!"
