I hadn’t noticed the tag 乳テント (“boob tent”) until recently. I’d noticed the effect of fabric being stretched taut in a well-filled blouse, just not the name for it. It’s not a huge category, although there’s definitely a tendency for huge things to get filed under it. Such as Ryotas, although fan-artists also go for the vacuum-sealed look with her as well.
Markdown formatting and simple HTML accepted.
Sometimes you have to double-click to enter text in the form (interaction between Isso and Bootstrap?). Tab is more reliable.
