Faster and faster I pumped, trying to make the plunges as long and deep as possible. On one of the downward plunges my foot slid on the carpet and my ...crotch slapped down all the way to the chair seat. A startled yelp issued from my mouth as I fell and was impaled on the rigid rubber prong. I just sat there, my cunt lips and asshole squashed against the chair seat, the cock buried in my belly and my entire cunt pit burning with astonishment.I realized I had the whole thing up inside me then. I. "I'm nearly there!" she then cried.I fucked her more and more enjoying every second of it, then as she pulled on her tits and plunged the wooden toy into her pussy, I suddenly felt her clench."Yes! YES!" she cried before screaming louder than anyone I had ever heard as her orgasm hit!"FUCK!" she groaned as she shook on my cock unable to stop her self, as she did I felt her asshole clench on my cock and instantly I had to stop, but with her loud climatic cries and her asshole squeezing my cock I. The slowly intensifying heat as I approached her groin made my trouser leg strain under the pressure of my gradually growing erection, which made her whimper ever-so-faintly as I pressed it against her leg. Her hand curiously explored my torso and made its way to my now-bulging crotch. She ran her fingers along the length of my cock and then squeezed it, and in that moment I no longer saw that young frightened girl, but the woman who she so desperately wanted to be. Desire filled me and I spun. Katherine exclaimed, "Mom, what's with you? You looked like you've just been run over by a truck!" I do?" Outwardly, Susan seemed fresh as a daisy, with her hair combed, her face washed, new dabs of perfume subtly applied, and so on. She was surprised they'd caught on.Suzanne nodded. "You do. Oh, wait! I know what it is: the spanking!"Katherine slapped her forehead. "Oh yeah. Duh!"Susan clutched at her chest, and asked with surprise, "You know about that already?! Both of you?!"Katherine smiled.
