Strict mother always warned me, "Don't enter my room without permission," and kept tight surveillance. Yet, when I returned home, I found her already inside my room, cleaning. In her hand was a tightly gripped DVD—her long-hidden, personal collection of porn. The scene unfolding before me was an intensely risky situation. Flustered and unsure how to explain, I panicked—until she surprisingly showed an odd understanding, claiming she needed to judge whether such material was educationally beneficial or harmful. In the end, we ended up watching the porn together. For the first time in her life, my mother watched adult content. At first, she curiously fired off questions, but gradually, she became absorbed in the images, growing silent. Glancing sideways, I noticed her lower body subtly shifting. As I witnessed my mother's transformation into a woman, I summoned the courage to take one final step—I made the decision to show her my erect cock for the first time.
