Confusing similar names keep you on your toes, like Serena/Selina and Reyna/Reina, in these sexy video examples of how even good girls have a bad streak.

Squelching the idea that beauty and brains are mutually exclusive of one another, students Reina Heart and Reyna Belle take a break from studying quantum mechanics theory by asking another student to give them the test answers—in exchange for them kissing one another for her voyeuristic pleasure. They do, and discover they like it, and this leads to a full blown first-time lesbian fling.

Angel Windell is Bailey Blaze’s brother's girlfriend, but Blaze reveals her feelings for Windell and, very orally, acts upon them. Serena Hill, caught stealing from their boss by an uptight Dharma Jones, convinces her for once in her life to be bad—which includes taking a reclined walk on the Sapphic side and a bedside in-depth exploration of one other’s bodies—inside and out.

In a moment of weakness, best friends Selina Bentz and River Lynn profess their love for one another. It goes a lot further and the living room couch becomes the place for their mutual inaugural lip service and fingering.

Overall, these girls don’t really do anything THAT bad, but what they do, they do well.
