Series: Oneesan and Yukkuri 6 (Boshiherondasu)

Oneesan has a pet marisa. She mated with a stray reimu (which obviously only did it to "enslave" the owner). Oneesan disapproves this marriage and abandons marisa, though she's kind enough to not hurt them and even provides a cardboard box as their new home. Let's see if a marisa who lived her entire life as a pet can survive being a stray with a pregnant deibu wife...

There's a sequel to this (pool #1608)
