Description: Gia Derza and Daya Dare are clinical researchers at B.R.I (Brazzers Research Institute), and they've got a model test subject today: Johnny Love! He's got a huge cock, he's responded to their ad, and he's ready to fuck! These girls aren't exactly robots, but they stay focused on fuckery and indifferent to Johnny Love, raunchily researching and overwhelming him with their perviness. The tests start simple (measuring the girth, length, and taste of his cock) but quickly intensify! The girls grind their juicy pussies all over him before leading him through a Gloryhole frenzy on their "free-use wall!" It's here where Johnny Love realizes there's no way out of this study unless he gets to the end: cums into the sample cup, wedged in Gia Derza's pussy. At the test's conclusion, with balls drained and researchers glazed in cum, Johnny Love only has one thought: "I'm glad I answered that ad!"
