[Crimson CROWN (Nikubou Maranoshin)] Training of a Childhood Friend ~The True Nature of the Female Hidden Behind the Boyish Appearance~

Dawn, a boyish schoolgirl with a tough reputation, discovers what happens when her childhood friend decides to expose the submissive girl hiding behind her tomboy image, beginning with a collar and chain in an empty classroom. Ordered onto him and made to obey, the flushed, sweating short-haired girl quickly proves how eager she is to serve, then squirms through vibrator play where she's forced to count every climax until she loses track. By the final act she's pinned and moaning through mind-melting penetration, her hidden feminine nature fully coaxed to the surface.
