Inaka no Kuro Gal JK to Kekkon Shimashita

Koichi quit his salaryman job to try to become a writer. However, he suffered from writer's block and he was unable to produce a novel. He decides to move out of the city to live in his grandfather's studio for a change of scenery. Koichi is stunned by the empty countryside, but there he meets Ichika, a tanned high school gal who seems out of place in the rural town. She is a sexually uninhibited girl who seems to be down to fuck at a moment's notice, but she is also a caring person, a good cook, and wants to settle down and get married, too. Koichi is attracted to Ichika, and he wants to make her the heroine of his novel… Somehow, they end up living together! When Ichika invites him to have sex and make a baby with her, will Koichi be able to hold back long enough to finally complete his novel? This is a slightly naughty story about how a sexually uninhibited girl becomes married to a novelist and have a child together. (Source: ComicWalker, translated)
