Obsessions (1969)

Obsessions (1969) is about a student who moves into an apartment that has a peephole. He can't help his curiosity and starts looking through it to see what his wild neighbors are up to, but he thinks he witnesses a horrible crime. He becomes obsessed with spying on them and finding out exactly what happened. 

We're totally obsessed with the beefcakes in this movie! Dieter Geissier makes us feel dirty when we see his bare ass as he gets out of the shower. Tom van Beek vigorously makes out with a woman naked, but we only see sidebutt. That bit of buns is enough to leave us wanting more...which we get! Tom and Dieter both bare their buns and we are obsessed!
