IBW-266 - 15 Girls Obsessed with Sports Bras: 4-Hour Full-Time Lesson

I was looking forward to this since there aren't many works like it, but... they put her in a sports bra only to lift it up and expose her breasts immediately. There are so few scenes where she actually keeps it on. It was a letdown. If you're just going to expose her breasts, what's the point of the sports bra? I wish they had kept the sports bra or junior bra on even after taking off her clothes. Plus, I wanted to see her cum on the bra at the end. Since underwear is a no-go in junior idol IVs, I'm hoping for works where loli-style actresses keep their sports bras or junior bras on throughout.
