The person who lived next to the new residence was a plain-looking big-breasted woman! I became strangely curious and investigated her, only to find out she was a famous underground streamer! The man couldn't calm down after watching his neighbor's perverted stream, so he lay in wait for the underground streamer and barged in to develop her nipples! After making them his personal nipples, he would even interrupt her streams, performing nipple development live in front of viewers! If she wears nipple tights and teases him, she'll beg 'Touch my nipples...' to the point where worthless nipples are completed!
