If a son-in-law is wandering around the house under the same roof in a defenseless state, there's no way he can hold back his excitement!! The father-in-law who is working away from home and the mother-in-law who is often on business trips. As the son-in-law spends more time alone with his mother-in-law, he becomes more aware of her alluring body!! The longing for the fifty-year-old mother-in-law turns into lust!!
