I ran away from home because of an argument with my family, not knowing who to rely on in the countryside, so I decided to go to the city to stay at my sister-in-law's house for a few days.
My brother lived at my sister-in-law's house and with her parents, so I called her to ask for permission first and luckily she agreed and promised to keep it a secret from my brother that I had an argument with my family and ran away.
When I met him, I said I was going to the city for a week and of course my brother didn't suspect anything. My sister-in-law's parents treated me very well, seeing me as a member of the family.
Since living with my brother's family, I accidentally discovered that my sister-in-law was very beautiful and "delicious", my male instincts began to rise, I craved to have sex with her, to fuck my brother's beautiful wife's pussy...
