No-frills sex scenes in luxurious surroundings, with the girls in neat white blouses and plaid skirts and the guys, well, in various clothes, who cares. Each scene opens with a solo by the girl, well-edited with black and white and color footage slapped together. After that, the coupling begins, with the well-known her-oral/him-oral/three-positions/pop flow chart thumbtacked to the wall as a guide. But hey, there's a reason it's a classic.
Good camera placement and excellent choice of female talent with enthusiasm to spare. The guys are two serviceable pros and a guy who passes muster, no problems there. Phoenix Ray shows particular promise. Keep your eye out for her.
