“He wants to watch, I’ll give him a show.” she thought, pressing her body back against the cold glass. She slid against it, enjoying the cold pressure against her nipples. The fact that he was watching made it even better. Her hands slid down, brushing across her hair, slowly caressing between her legs.”
“Okay, and this one?” mom said, interrupting me.
I noticed a change in her voice, and glanced up at the mirror. Were her legs parted a bit? I couldn’t be sure, but I thought I could see up past her knees.
“Well, I” I began, tearing my eyes away from the mirror. “It gives her control. She decides just how much he sees. And she can do it and still pretend not to know. At the same time he can go on believing she doesn’t know, and as long as she doesn’t know, it isn’t really happening.”
“Strange logic, but I guess you can make a case for it.” Mom said.
“Another one?” I said, looking over my shoulder at her. She was laying back further, her hands folded across her stomach. I watched her for a moment, admiring the swell of her breasts, even lying down, they pressed against her robe.
“Uhm, yeah.” she said, not opening her eyes.
“The house was quiet, strange for the middle of the afternoon. The quiet made him quiet, and he slowly padded up the stairs, pausing when he heard the first moan. It was not a moan of pain, that much he knew. He waited silently, listening for another, just to be sure. The next moan was a bit loader, with a sense of urgency to it. He moved forward, careful to not make a sound. His sister’s door was open, just a crack, but open. He moved up to it cautiously, the sounds already affecting him. By the time he peeked in, his cock was already pulsing, straining to escape his shorts.
The view in the room made him gasp. He jerked back, prepared to dash to his room, but nothing happened. Easing forward he looked back in, taking in the scene slowly. Jennifer was on her bed, knees up, legs parted. Her fingers were between her legs, caressing her mound. From where he stood, he could see the moisture gathering in the soft folds of her womanhood, as each caress of her fingers made her legs tremble.
He pulled out his cock, slowly stroking it in time to her movements. She gently eased a finger inside, rubbing gently as her hips arched upward. Her eyes were closed, giving him courage. He eased the door open a bit, giving himself a better view. Her huge tits hung to each side, their mere size forcing them to sag. The hard nipples poked up proudly, begging for attention. Mike struggled to resist the temptation to enter the room as Jennifer added another finger to the one already caressing her inside.
Her hips began bucking upward, slowly at first, but quickly become almost frantic. His own movements followed suit.”
“Enough!” Mom said, her voice strained.
I glanced into the mirror. Her robe was parted well past her knees. She had tucked the upper portion between her legs, which pulled the fabric tight against her tits. She was staring at me, her mouth slightly open. Even from where I sat, I could see her nipples poking hard against the fabric of her robe.
