Soon the rhythmic and well designed steady in and out motions were there to mesmerize us both. Mother would start her musical writhing and wiggling he... ass towards him.As the pace of motion changed with rapid fucking in her, heavy gushing noise produced by her pussy would be clearly heard in the hallway as it consumed daddy’s fucking pole which he plunged deeper and deeper and groaned louder as well. Even the sound of sex would tell when they were drenched in sweat and close to hit the orgasmic. I tell him would he like to watch some tv or a movie to which he replied that not now as he had to go down as people will ask where the security guy was. He said he will be free around 11:30 pm as the night watch man comes then and he can come then only, I tell him to come whenever he gets free as I was going to be awake for a late night because tomorrow was a holiday. He smiles and leaves.The bell rings at 11:30 and I see him in his uniform all hunky standing at the door, I let him in and tell. This is odd since my brother in law is not into sports like that but would watch with me occasionally. Apparently they were set up by their friends and just clicked. Our relationship was pretty cordial and grew more as a buddy type. She joined my fantasy football league and would watch football with us from time to time. One of the things I enjoy when hanging out with her and my brother in law is when we go on vacations or hit the beach. She always wore these boyshorts that would show off her. “And the bra.” He added.I arched my back and let loose the front hook, my titanic titties bobbling into view. They don’t sag much by the way…but at FF, you’re bound to get a little hanging action.This didn’t seem to both Black.“How big are they?” He asked.“GG Cups.” I lied. Somehow I just had to be big enough for him… worthy… first time in my life I ever tried to up-play the size of my already huge mammaries.His second slap was harder then the first, and delivered to my left tit with the back.
