Dr. Chrystin, a seasoned gynecologist, begins Isabelle's comprehensive exam with a gentle thermometer check, her professional demeanor betraying a hint of excitement. She lubes up a speculum, parting Isabelle's thighs, revealing her glistening, eager pussy. But today, Dr. Chrystin has something extra in mind. She retrieves a slim, metallic anal speculum, her eyes meeting Isabelle's as she lubes it up. Isabelle gasps as the cool metal presses against her tight asshole, her heart racing as Dr. Chrystin slowly inserts it, her fingers brushing against Isabelle's clit, sending jolts of pleasure through her.
