If she wanders around the house in a defenseless state under the same roof, there is no way the son-in-law can contain his excitement!! The father-in-law is away from home on a business trip and the daughter-in-law is often away on business trips. The son-in-law is spending more and more time alone with his mother-in-law, and he is interested in her voluptuous body!! His feelings for his mother-in-law in her fifties turn into carnal desires!!
