In the intro, the gooey stuff is poured over a girl from above her and she plays with it for a little while.

On the first scene, a man fondles her all over while the slime is slowly poured over her. She gives him a wet and messy lotion blowjob and then they have sex in the goo.

On scene two, a guy in a classroom pours a bottle of that goop over her and then they have sex and as it keeps being poured over them from the top. She wears glasses in this scene.

On scene three, a girl is in bed and the stuff is poured over her while she plays with herself and gives some guy a messy, slimy blowjob.

On the fourth scene, she's dressed up in a pink nurses uniform and pretty much uses the guy as her own slip-n-slide massage toy and gives him a blowjob and has sex too.
