My sister came to live in a new house with her wife and forced herself to go to school. My sister seems to be interested in me, and she is tempted with all her strength. i'll pull it out every day and stop our family plan.

A new house that lives together with my wife. I was talking to my wife about making children in earnest soon, and my sister came to live together with me for the purpose of going to school. It would be nice if I were just living together, but my sister seems to be interested in me and tempts me with all my strength. Every day, we pull it out and stop our family plan. At first, I strongly refused to do so, but my cute and erotic sister gradually attracted me more than my wife. Sperm produced by the sex with my wife is ultra thin like water now! my wife, sman!
