Mother of a friend - the final chapter - Matsuoka Sanna

Sanna cheated on her husband and son. I don't feel like being in trouble, and if I do it well, I thought that I could enjoy the insufficiency while maintaining the yen of my family. One day, a friend of my son’s who was coming to play asks me to call him. Sanna desperately tries to erase the facts, but her son's friends have been complaining and presenting about the conditions for exchange of remarks. If you want me to be silent, I'd like you to have an affair with me."
