Sister-in-law wants to stay, I am banned by my wife from having sex and the consequences

My sister-in-law Riho found out that her husband was going out with another woman, so she left home and came to stay with me. During this time, my wife did not allow me to have sex with her for fear that my sister-in-law would find out. But she has been staying at my house for a month now!!! Because we just got married and I work from home, my desire is extremely strong.

My sister-in-law seems unaware and keeps wearing revealing clothes, not wearing underwear, pushing me to the limit of endurance. And with my wife away, we drank together, the alcohol making me unable to control myself and I rushed towards her, releasing all the frustration that I had been enduring for the past month...
