Sister-in-law's temptation 2 ~Under the same roof with my brother's lewd wife~

I'm staying at my brother's wife's house, and I'm completely in love with Karen, his extremely beautiful and kind wife. One day, my brother was on a business trip, and I was alone with my sister-in-law! He kept me interested by showing me how he was having sex with my brother's best friend, and gave a blow job to my friend, and finally went to my room at night... A situation that every man dreams of at least once, the second part where he is seduced by a sister-in-law with whom he is not related by blood. Living under the same roof with Karen, a beautiful and lewd older sister.
