Big brother lives a harem life of babymaking sweet *luurrrrv* with four adoring imoutos!

Welcome to the countryside, where a protagonist returns to the house he grew up in to find his little sisters have done some growing up of their own. Which one will become oniichan's bride? They're all competing for your affection and throw themselves at you, wombs fertile, in a soft girlie attack. Kick back and enjoy the dewey sweet slow life with your harem of, at home, around town and at the local festival.
