She came over meekly and hoisted a barbell that was nearby, and she proceeded to do a set of squats. I walked around behind her to observe her form, a...d it nearly gave my cock a spasm to see those cheeks bouncing up and down like that. They were straining the fabric of her yoga pants so badly that I thought she was going to split a mile-wide seam in them.I made her keep doing the squats for about ten minutes, till she was good and hot, and then I gave her a break. "Stop!" I yelled, and she. “Now you will eat my cunt until I tell you to stop if you hesitate, I will punish you, so you see you have no choice.”I moved forward, my nose parted her hair, it was matted with her juices and the aroma blew my mind.I wondered whether I should lick her swollen lips or dive in and suck the slick flesh.Another HISSSSS and fuck my ass was on fire again.“I told you to eat my cunt, Nicola.”Quickly I dropped my head to lap at her wet entrance. Eager to avoid another stroke of the flogger I greedily. Still, I persevered (I can be stubborn that way), while Mom held the handlebars like she had when I'd been little."Wow," she said at last. "I was looking for two, I didn't think it would go so far." It was kind of fun," I admitted. "I'm not sure I'd do it again, at least like that."She laughed. "Yeah, it was a bit much."We went home and took a shower. Now I'd showered and bathed with Liz all of the time. We didn't do anything sexual. For one thing, she was my sister. Guys fantasize, though.Mom. She squeals with pleasure and or pain as his massive cock enters her virgin pussy.Is she dreaming her fantasy? No. She knows its not a dream. But its not a nightmare either.She goes with it none the less. She enjoys herself. Moaning and groaning.They fuck until long after the sun disappears. Nobody else anywhere all day. They fuck all over the park as the moon shines over their glistening intermingled bodies.They find themselves fucking on the bank of a little park lake. They skinny-dip to cool.
