Amanda is undeniably beautiful and was pretty good in this scene, though she seemed a bit overwhelmed by Rocco and maybe a little "too good" for the scene.
On the other hand, her sucking his dick and getting fucked from behind in broad daylight, in the middle of a public park, with people wandering around was pretty cool. Buttman finally made them stop and rushed them to a hotel room. Here is the IAFD page on the movie, along with links to six reviews of the movie. Hopefully they'll help you decide:
