"My sister-in-law lives with me and my wife. Whenever my wife and her sister go out on errands, I grabbed both of their used underwear to smell their pussy juices and cum in my sister-in-law's used sock. She leaves dirty underwear in the bathroom every now and again after she comes home from work. I absolutely love the smell of her pussy after she comes home from a long day of work. I hope I get to fuck my wife and her sister one day"
