Because he wanted to marry his grandchildren, his father-in-law cruelly raped his daughter-in-law until she became pregnant

Rio is under pressure to give birth to his grandchild. One day, at the suggestion of my father-in-law, I decided to go on a hot spring trip with my family. However, his mother-in-law ordered him to abstain from sex for a month before the trip to give birth. On the day of the trip, Rio was refused sex by her husband. On the other hand, his father-in-law also tried to hold on to his wife but he refused. Two people who were so sexually excited went to a hot spring to soothe their bodies. And the father-in-law happened to witness Rio taking a bath.
