I think this scene is 45+ years old What makes it timeless are a couple of things. Terri is fawking gorgeous. She looks like a college student. I bet she's no older than 19 or 20 here. The lucky professor looks the part. He's clearly at least double her age. It's funny. As she continues her amazing BJ her grade rises like the professors load in his nuts. The BJ takes only a minute, a realistic time given Miss Dolan's beauty and skill. Finally the natural lighting on her is perfect as he releases his load on her smoking hot body. Humor, youth, beauty, and cinematography combine to produce a clip for the ages.
