孫便器　先行＆おまけ (Pixiv Fanbox)

父親は娘を調教する場合、歪んだ愛情の発露という線もありそうですが、おじいさんだといよいよ鬼畜感が増す気がします。共働きが席捲する今、調教役としておじいさんが活躍する話も増えたりするんでしょうか…。4枚目、5枚目がfanbox限定絵です。 ===== In the case of fathers training their daughters, it may be an outburst of twisted affection, but in the case of grandfathers training their grandchildren, I feel the sense of devilishness will increase. Now that co-workers are taking over, I wonder if there will be more stories of grandfathers playing the role of trainers.... The fourth and fifth pictures are fanbox exclusive.
