LOS ANGELES, Calif. – Brenna McKenna, the tight and toned, all-natural alt Jersey girl, is “returning to college and taking a chemistry class” in her Reality Kings debut, setting off a chain reaction of sorts in a hot three-way scene.

In “Risky Reactions,” Brenna dons a lab coat and goggles for a class lead by GI Joey. Along the way, a new transfer, Selina Bentz pops in for her first day of class. Selina is looking to establish good chemistry with her new professor, so she unbuttons her top to show off her pert breasts while cleverly using her lab coat to shield the view of her fellow students. Professor Joey is somewhat less discreet, grabbing his cock and whipping it out for Selina to suck.

Like Selina, Brenna is another eager-to-please pupil, who introduces herself and says she’s looking for a lab partner. Soon, Brenna and Selina are competing for Joey’s attention, but he’s inclined to distribute his interest across them both, if you catch my drift.

Brenna and Selina lick each other and Brenna soon finds an alternative use for a test tube: Using it as a dildo until she squirts! The girls take turns riding their professor’s big cock, driving him towards an inevitable climax. In the end, it’s a good thing they’re wearing eye protection, as Prof Joey takes aim at their pretty faces as a target for his hot cum load. None of this is likely to help the school maintain its accreditation (or Joey keep his tenure), but it sure makes for more interesting viewing than a typical day in a college chemistry lab.

“It was fun returning to college on a porn set,” Brenna said. “Fucking a test tube was a genius and is a great squirting technique. I love this scene, and it’s a great debut for Reality Kings! Watch it, tell your friends, and let RK know how much you enjoyed it, so you’ll see even more of me on the site!”
