Shyly looking down, smiling with a flustered and confused expression—this is Keiko. The latest release from popular M girl Saeko Honda features a compact, intense play session where her perfectly round ass is repeatedly slapped and teased. In a girls' dormitory bedroom, an older female senior playfully touches her breasts, navel, groin, thighs, and anus, each touch sending waves of nervous excitement through her. Bound with handcuffs and a collar, she's dragged around and forced to crawl on all fours across the floor. Despite her embarrassment and hesitation, the pleasure slowly takes hold, and her struggle to suppress her arousal feels intensely real and captivating. Keiko, overwhelmed by the pleasure of M training—clearly, she's still deep in her masochistic upbringing.
