My ideal female boss, Ai-san. Strict during work hours, yet undeniably beautiful and captivating. Begging her repeatedly to practice sex with me, we end up doing dry humping in the office. Before I know it, I accidentally slip inside—“Ah! It went in!”—and let out a moan. Once my hips start moving, I can't stop; her pussy feels incredibly good, and I absentmindedly (or so it seems?) end up cumming inside her. Under the guise of "practice," things quickly escalate into full intercourse, making this gradual progression into actual sex the highlight of the story.
