Of the beauties in this feature, Susan Vegas, Stephanie Rage and Tamara Lee turn in the hottest sex performances; and all the girls are all very much worth watching. But if customers choose this title because they think it’s a comedy, forget it.

In a tried-and-true plot form, couples sign up for a sex research project and they “study” away from the cameras. Maybe the comedy is in a couple (Eric Price and Stephanie Rage) who think being the subject of sex research would make a good vacation, but who never manage to find the house where the study takes place. Well, it turns out that when they return home, the researchers (Peter North and Tamara Lee) have bugged their house and are watching every luscious move. Some good sex, no comedy in a decently mounted sexvid.
