My older sister and her husband came home unexpectedly and found me fucking the brains out of their son, Teddy, my nephew, who just turned 19. It was such a flat bust I could not do or say anything, so I just said, "I hope no one's feelings are hurt." They first gave me the silent treatment but Teddy intervened and lied, saying he had practically r**ed me. Actually, it was quite the reverse of that but I kept quiet. What they don't know is that I fuck Teddy every spare moment we get. The two of us can't get enough out of each other. We knew it when he turned 15 and I first saw his joint in the shower. He had been beating off in the shower with soap on his fat cock and his tight fist going to town on it like a jack-hammer. I just went for it. The day after we got caught and Teddy lied to his parents, the first chance I got, I speed-sucked on his cock till it shot off into my mouth.

The weird part is that I know damned well that my brother-in-law, Teddy's dad. is dying to fuck me. He can't stop looking at my tits, ass and crotch. I love my sister so I'm not going to do him, ever. He can ask Teddy how it is and what it's like.
