MIDA-570 | Her younger sister is a glamour model with massive K-cup breasts! She pretends to be extremely protective of her nipples, but at home she's incredibly careless! Her breasts are so big that they slip out unintentionally many times. Koikawa Komomo

I was going to stay at her house for the first time and met her younger sister, Komomo-chan, for the first time. Komomo-chan usually keeps her chest flat and well-protected when going out, but at home she's completely unguarded, with her breasts spilling out of her bra. And then I found out she's also a gravure idol that I secretly support...! Every time I saw her breasts slip out, I got incredibly excited!! She was wearing such revealing clothes, it was like she was showing them off on purpose! With such a parade of breast slips, I couldn't contain my excitement any longer...
