"DO IT," he commanded. The next thing I know I was cleaning his cock with my tongue. When I was finished I stood up and said, "Thank You Sir." Thank m...e for what, girl?"I hesitated and got another slap. "For shooting your cum in my a-pussy and letting me clean you, Sir, I sobbed." Good girl," he said as he gently rubbed my ass. "Now go make dinner. After you clean up tonight, come back for our nightly drink and I will give you this book." He pointed to the book of "RULES". "And put these on." He. “Oh I know I said I wanted you to do it; that it would be okay but I didn’t mean you should go behind my back and fuck someone in secret. That wasn’t fair; that wasn’t open and honest. And if we’re anything to each other I thought we were honest.”I felt sick. I felt ashamed. All my online friends had been right!“Have you been with him since you told me?”“No,” I shook my head.“And if I ask you not to, you’ll never see him again? You really mean that?”“I really mean it, Pete,” I insisted, my mind. He improved his rhythm, making my throw my head back in ecstasy, eyes tight shut. I was so close to cumming in his mouth when suddenly, he pulled back. “What was that for?” I said in disappointment, looking at him. “Hey, I’m not finished yet, that was just the appetizer. Now grab that pillow and prop your butt up with it. Trust me, this’ll be good for the both of us,” he said reaching into his bedside table for something. He rummaged around in it for a second, extracting what looked like a tube. I kissed my brother in law grabbed his belt dropped his pants and sucked his dick a little bit then would send him texts while we visited. And even the rest of the evening eventually me and my husband would talk about me fucking other guy's when we fucked it made sex better for us both. I just acted like it slipped out of my mouth I want to fuck your brother and I want his cum. He got hard as hell so green light we played that fantasy out for a little while. But it's his brother not someone.
