My wife and I both have movies we remember as being wild and hot for our developing minds in the 80’s. We want to see each other’s.

1. 80’s movie set at a school,  likely a college. Scene of a dean type character having sex with secretary while he is dressed as a shark and she as a swimmer.

2. second movie is a 80’s beach movie. Looked very much like Miami beach. Scene I remember involves lots of girls topless with guns. Anna belt on. Maybe a tank?  This is not Revenge of the Nerds 2 which I know has a similar sounding scene. In this movie I think the people are trying to save the hotel they work at? Not sure why the guns or who they were going to fight.

Thanks!
