My son and I have been intimate for three years now. When he went to university in Tohoku and was struggling to adjust to his new life, I gave in to his advances, intending to comfort him.

This will be our third time, and I'm going to lie to my husband, telling him I'm going on a trip with friends, so I can see my son...
