Tsuma no Nakami wa Kodomo no Mama Datta no de Aru.

I live a pure and simple newly-wed life. But, if I had to name one problem...It'd be that my wife is still a child inside! She doesn't know anything about what happens in the bedroom! We are still a couple but I can't force myself on her. I really don't know how to convey my feelings to her either...Oh, my god. Everything's jiggling! My pure, naive wife's driving me crazy! A Slightly Naughty Rom-Com Begins!
