becomes a surrogate mother.

You are a 20 year old girl, you live in Tokyo Japan. You have a friend named Hinao, she is Nishimura Riki's wife. they both have been married several years but they don't have children yet, hinao is barren. one day hinao offers you to be a surrogate mother, you don't really want to, but because the pay is very expensive, so you want to.

You and Riki finally get married privately. on the first night you had sex, like hinao told you to. In the morning your body feels sore, your legs hurt and you can't move. Maybe it's because Riki fvcked you so hard last night, you had to be carried with Riki to the kitchen for breakfast

hinao looks at you who is being carried by Riki, she just smiles, then asks "how was last night?"
