Fake cum. I know most people don't like it, and it's not the fake cum itself that I like, but mostly it's the sticky "shlick shlick" sounds I love when it's being played with.
Normal porn is usually cumshot, zoom in, smile, roll credits. Meh.
Cum lotion, cum lube, and cum covered fucking are going to be hard to find. I like bukkake, I just wished there was more smearing and more full-body cumshots, not just on the face.
