Sakurai Imouto from the manga Kanojo no Imouto ga Kyonyuu MiniSkir JK de Koakuma-kei (彼女の妹が巨乳ミニスカJKで小悪魔系, which translates to something like "My girlfriend's little sister is a big-breasted, miniskirted JK with a devilish personality") by the Aohimo Familia circle (Aohimo & Chilt). Another character with changing breast size, it's mostly on the huge size rather than merely large.

Trained for 960 steps from a variety of manga panels. Was trained on some NSFW so take precautions if needed
