CHATSWORTH, Calif. — Nina Hartley's "how to" line from Adam & Eve Pictures has a special new installment arriving this week: Nina Hartley's Guide to Great Sex During Pregnancy.

Featuring adult stars Tiffany Mynx and Violet Blue, both in very advanced stages of pregnancy, the instructional vid was directed by Ernest Greene and attempts to dispel the myths and taboo association many attach to sex during pregnancy.

"I've wanted to broach this subject for years," said Hartley, who at one time was a practicing nurse. "There's a real curiosity and a lot of misinformation on sex during pregnancy. I felt it was time to set the record straight ... and I believe the public is ready to accept that a pregnant woman can be a sexual, desirable woman."

Along with in-depth question and answer sessions, the title features two hardcore demonstrations, one a lesbian bout between Hartley and Mynx, and the other a straight coupling with Blue and her child's real-life father.

Will Tori Spelling star in the sequel?
