Bonnie Rotten is a mad scientist who has set out to find the perfect sexual partner. So far, she's had no luck, and every single subject she's brought back to the lab cums way too quickly! She runs test after test, but nothing seems to work. Nothing, that is, until she gets a new specimen for her erotic experiments: Brick Danger. It turns out that Brick has everything Bonnie has been looking for this whole time, from his big fat cock to his impressive stamina. In order to prep her subject, Dr. Rotten gives Brick some super sloppy head, slobbering all over his big dick and deepthroating it down to the base. She takes it balls deep in her pink pussy, pretty face, and finally in her tight little asshole, pussy squirting as she cums all over her lab. Finally, Brick gives her a big facial cumshot, officially making himself Bonnie's best experiment ever!
