Introduction
* Synopsis
I am a simple man who is overwhelmed by the hustle and bustle of everyday life. The only moment I relax and unwind is when I watch my favorite streamer, Tsubasa-chan, on the video site “MiruDOGA.” She is friendly, has an addictive personality , can sing very well, and on top of that, she’s got really big boobs. She seems to use her large breasts as a weapon, often drawing attention to them in her videos when the opportunity arises.
One day, during a live broadcast, she said, “It feels like my breasts have been getting bigger lately…” From that day on, Tsubasa-chan’s breasts began to grow dramatically, quickly reaching an impressive size that is rarely seen on gravure or even porn actresses. When you compare archived footage, the extent of her growth is astounding.
Tsubasa-chan quickly became popular on the internet for having such large breasts, but it seemed like she was having a hard time with the clothing due to her ever increasing bust size.
One day, an accident occurred during a broadcast where her clothes could no longer withstand the weight and size of her breasts and they burst open. Tsubasa-chan was immediately banned from “MiruDOGA,” but the broadcast was re-uploaded to various other sites and her breasts became widespread on the internet.
A month later, after she stopped updating her social media account “tsubuyaita-,” I wondered if I would ever be able to see her broadcast again. However, one day she suddenly uploaded a video to the adult broadcast site “45DOGA.”
Tsubasa-chan, whose breasts had grown even larger than before, said the following in the video:
“I really love it when a lot of people look at me… So please, I would like everyone to subscribe and follow me as my breasts grow larger…”
After moving her activities to the adult site, Tsubasa-chan’s breasts continued to grow even larger and heavier, and she began to lactate. It seemed every time she streamed, the content of her broadcasts and videos became increasingly explicit…

Editorial Review
Virtual idol culture collides with breast expansion fantasy in this premise-driven doujinshi that leans heavily on the voyeuristic appeal of watching a streamer transform in real-time. The work occupies a niche intersection where parasocial fandom meets body modification fetish—a combination that remains relatively underdeveloped in the broader adult manga landscape despite the obvious thematic synergy between livestream culture and growth narratives.
What distinguishes this entry is its framing device. Rather than depicting a standalone fantasy scenario, the narrative centers on archival comparison and the gradual documentation of physical change across sequential broadcasts. This gives the work a pseudo-documentary quality that contrasts with more abstract expansion fantasies. The synopsis emphasizes the protagonist’s role as an observer tracking incremental transformation—a curator of evidence—which taps into the specific appeal of before-and-after comparison content that dominates expansion communities. The choice to anchor the fantasy in a recognizable digital platform (MiruDOGA, a clear parody of streaming services) rather than isolated scenes grounds the escalation in a familiar social context, making the impossible transformation feel almost plausible within its fictional ecosystem.
The production format (CG with illustrations, offered in JPEG and PDF) suggests a hybrid aesthetic typical of independent digital artists working this space—likely balancing illustrative variety with photorealistic rendering, though the exact visual approach remains unclear from available details.
This will resonate strongest with audiences already invested in both parasocial streamer dynamics and dedicated expansion fetish communities, particularly those who appreciate narrative justification for their preferred content rather than scenarios presented without context. The work’s specificity to streaming culture may alienate readers seeking more traditional fantasy framing.
A competently executed fusion of niche elements that knows exactly which audience to target.
