The busty, unsophisticated woman next door is a well-known underground account. She was assaulted during a live stream, resulting in nipple development. (Tanaka Nene DRPT-069)

After moving, I found out my next-door neighbor was a seemingly plain-looking girl with huge breasts! She piqued my curiosity, and I discovered she was a well-known underground livestreamer! Seeing the man next door getting excited watching pornographic livestreams, he secretly waited and attacked this underground livestreamer, starting to develop her nipples! Once they became his exclusive nipples, he joined in during his livestreams, performing lewd acts in front of his viewers! When he put on her bra and stimulated her, she even actively asked, "Touch my nipples...", completing a completely self-sufficient nipple development!
