Inazuma’s Embarrassing Secret. (Pixiv:October 30, 2015) (Patreon)

    Inazuma was seduced by Atago to wear a diaper to bed.  As a result, she realized the warmth, security, and comfort of peeing in diapers.

    However, the sister ship, Ikazuchi, found out about it.  With her meddling, motherly nature, and desire to be mean, Ikazuchi forced Inazuma to pee in her diaper and changed her diaper.  Seeing Inazuma so entranced by the comfort of his diapers, Ikazuchi began to enjoy treating Inazuma like a baby.  Furthermore, although she was not aware of it, she was also beginning to feel a certain emotion.

Since there are more than 10 images this time, I've attached a zip file to save them.
