In the dimly lit room, the initiate's heart races as she's presented with a thick, veined cock for her first verification challenge. She tentatively sticks out her tongue, tasting the veteran's salty, slick tip. With a deep breath, she takes him into her mouth, her lips stretching around his girth. She struggles at first, her inexperience evident, but she's a quick learner. She finds her pace, her head bobbing, her tongue swirling around his sensitive flesh. The veteran's grip tightens in her hair, guiding her, his hips thrusting gently to meet her movements. She looks up, her eyes watering, but her determination unwavering.
