Dr. Feelgood puts his unconventional sex therapy to the test with young Eva, a beautiful 18-year-old virgin needing a cure for her sexual inhibitions. In his office, he starts with a heated discussion, her voice barely above a whisper as she describes her fantasies. Then, he guides her hand to grip his throbbing cock, teaching her the art of a perfect blowjob. Eva's eyes widen as she takes him deep, her lips stretching around his thickness. He fucks her mouth hard, her moans vibrating against his shaft. Next, he bends her over the desk, her round ass in the air. He spanks her, leaving red handprints, then pushes his cock into her virgin pussy. Eva gasps, her tightness clenching around him as he pounds her hard, talking her through every sensation until she cums, her body shaking with her first orgasm.
