At around 20 minutes into Sensation, Luanne Gordon, is shown giving a simulated bj. We see Luanne’s breasts from the side and again as she walks around topless after. Half an hour later, we see Luanne’s breasts again as she is topless in bed. A few minutes later we see Luanne full frontal nude from the side as she is about to get a tan. Then 15 minutes later, we see her breasts as she switches clothes with another prostitute.
We also see the other three prostitutes Luanne works with at least topless briefly in the film. Unfortunately, I didn’t catch their names in the credits.
Finally, at 78 minutes, we see Kelly Campbell naked from behind as she gets out of bed.
