I ended up living with my brother and his wife for a while. At first, I didn't see my sister-in-law as a woman, but... My brother's wife, who had been sexless with him for over three years, was targeting me from the start and seducing me... I also started to notice her... Finally, we couldn't hold back anymore and went at it while my brother was on a business trip! Since she responded so well, I got carried away and thrust up hard from below, pistoning at high speed! We made each other cum so hard that I almost lost consciousness multiple times!
