.. I was going to need a pill pretty soon. This was driving me insane."After your bath, put on your new clothes, Dani," Mom told me before closing the...door behind her. "Brush your hair and put on some makeup too; use mine, okay?" I can use your makeup?" I was surprised at that.I had some of my own, but very little and none of it was serious. Like bubble gum lipstick and some rouge, glitter eye shadow. It was all kid's stuff and I always wanted to wear the real stuff, but Mom always said I was. I was flaunting it ... for him.I mean, when I’m helping him out, that’s fine. I need to dress sexy if I’m ever going to help my brother cum, and as a sister, that’s what I’m here for. I mean, that’s what I signed on for.But when we’re not ... y’know, doing that, it felt kind of weird to have him ogle me.We had to leave straight away, or we were going to be late, else I would have gone back upstairs and changed. As it was, I was tempted to skip the whole thing, but I guess I felt I was. As she finally stopped cumming, Cheyenne fell to the floor exhausted. She was satisfied. For now. As she looked at her mother, covered in cum, seeming to be close to giving birth to an elephant, her cock began to twitch again growing larger and larger until it was about 21 inches long and 2 1/2 inches wide. Her mother licked her lips at the sight of her daughters massive cock and she began to deepthroat it once more. After five or six minutes Cheyenne was writhing in pleasure her cock hard as. Still, she was as good as her word.Before I could answer, her hands closed on my shaft, and began to stroke it, slowly, up and down, up and down. All thoughts of speaking left my body, as I got closer and closer to a climax.As soon as I moaned out "I'm gonna come…" she grabbed a tissue, held it in front of my dick, and caught the cum in it. Then she got up, and threw it out. Before she joined me, she took off her nightgown, and then motioned for me to roll over. I still saw her naked breasts,.
