Schoolgirl chemistry with her teacher

This schoolgirl is awful at chemistry, she looks like she has no idea what the hell she's doing. It's because she indeed doesn't. She also looks one step away from drinking some of that stuff and that's kinda weird, too. Her big-dicked teacher with a goatee gets fed up with her lack of chemistry skill and since she had to take off her half-top and her lab coat, well... He has some different ideas about her now. Her lil' boobies are extraordinaire and she looks while still wearing those protective goggles that do nothing.
