So I got undressed. I felt totally foolish standing there without a stitch of clothing on in the middle of the living room with my aunt and sister loo...ing on. The shame was causing me to have an erection."Carol," my aunt said, " you're going to have to learn how to take control of your brother, and give him orders. Look at his penis. I think he needs to masturbate. What do you think?"Carol looked at my aunt blankly, and before she could answer, I interrupted, "No I don't, Auntie. I did it so. Bill opened his mouth and lowered it over my knob end. I felt that I was going to cum, but Bill grabbed my shaft and squeezed it at the base and the feeling subsided. Bill ran his tongue over my knob end then began to move his head up and down, taking more of my cock into his mouth with every motion. My wife had given me head many times, but this was a whole new experience. Bill sucked and wanked me until I tensed and told him I was going to shoot. Bill squeezed my shaft again and once more. " So where would you like to go?" I said."How about that burger place over across from the mall? I haven't beenthere yet and everyone says it's pretty good." Yeah it is. I'm up for that."She ordered an amazing amount of food for someone who looked like sheprobably counted calories to stay in great physical condition. But, as Ilearned over dinner, she just had a really high metabolism and could eatalmost anything she wanted. Not to mention the fact that she had aregular workout routine, plus. He needed some time to re-coup, but I was not ready for a break, so I sat on the edge of the sofa and spread my pussy open. "I think turnabout is fair play, don't you?" I said as I lightly ran my finger over my clit. "I'm so wet." I said and put my finger deep in my cunt. Then I did something he had never seen me do. Taking my finger out of my pussy, I put it into my mouth. "Mmmm, baby I taste so good. Wouldn't you like to have some?"He got on the floor, sitting between my legs and began.
