Marilyn Chambers serves as the narrator for this succinct guide to the art of anal sex. The instruction is very basic, and anyone with a fair amount of experience in this area probably won't glean much helpful information. However, the effort could be a very beneficial tool for beginners.

Lessons in proper lubrication, pace, breathing and safety are provided, and Nikki Nievez even good-naturedly demonstrates an enema to make sure the rectum is completely cleaned out before a dude sticks his penis in there.

Three very brief anal scenes follow without any other sexual acts included. All three ladies appear to have a fine time getting ass-boned, and they can take extra pleasure in the fact that maybe they're helping some viewers out.

Retailing: Reserve this one for couples and those looking to experiment with anal sex for the first time.
