The final installment in the series features a mysterious storyline where my childhood male friend suddenly transforms into a girl. Always cheerful and carefree, he used to pull shy me into class events and support me kindly. But one day, he suddenly stopped coming to school, and when I visited him, I couldn't hide my shock at his transformation. Returning home, still thinking about a female classmate in her school uniform, I decided to jerk off—just as my phone rang from his number. A high-pitched girl's voice shouted, "Dude, I'm in serious trouble!" I couldn't believe it—he had become a girl. That night, he showed up wearing just a loosened uniform shirt, pants pulled down, and panties. The sight sent chills of excitement through me. Speaking in a girlish tone, he said, "You're such a serious nerd, always keeping secrets. Please help me." I couldn't help but reply, "I'll help you." Delighted, she grabbed my hand, rapidly turning me on. She began touching my chest, stroking my hair, teasing my tongue—gradually dominating me. Then she whispered, "Sorry... you can do whatever you want with my body, just don't get mad at me," surrendering herself completely. Her words ignited my desire, and I started pushing her further. At first confused, she gradually lost herself in pleasure, begging, "I want more," and eventually pleading politely, "Please, give me more." Watching her like this, I realized she had completely become a submissive woman. As a virgin, I fulfilled my deepest desires by dominating her. Shocked by her transformation, yet thrilled by the thin line between breaking her or not, I reveled in every moment. This work captures the intense clash between her metamorphosis and my awakening lust. Experience it for yourself.
