Tell me, Saya's erogenous zones.

Developing the sexual sensibilities of active gravure idol Saya Tachibana! While my hands were shaking from nervousness, I had a parade of first-time experiences! She loses herself in sex in a closed room and continues to writhe in agony, gasps in shame as her joints are shown on a large monitor, and cums over and over again in her first threesome! Stunned by the huge amount of squirting! Reason collapses due to pleasure, and Saya Tachibana becomes an adult... 120 minutes of joy and climax!
