Your wife came to me with some disturbing news - she was looking through your phone and found hundreds of nudes of me, your big sister! Don't you know that's wrong? I decide to help you get over your obsession by letting you see the real thing - just get it all out of your system so you can never think of it again. I slowly strip down naked while asking you to compare my body to your wife's. Then, I call in my husband to suck his cock then ride him in reverse cowgirl until he cums on my tits. He leaves to take a shower, and I decide to truly fulfill your fantasy. You fuck my hard until you cum on my tits, too. Now let's never speak of this again, little brother!
