It wasn’t long before his head was bobbing up and down my shaft with the ease of someone who knew what they were doing. I tilted my head back a litt...e, putting a hand on top of his head as he looked up at me with those piercing blue eyes. A rush of pleasure shot up my body.I looked over at Oren who was watching with a slightly glazed expression of ecstasy. He was clearly hard although the tight shorts weren’t allowing much room for him. I wasn’t concerned, however, I’d learned that Oren liked. She gave her every opening to Gramps as well as to other well-hung men and big-titted women on those videos. In addition, she clearly had no compunctions about muff diving, even when one or both of the ladies had no muff, if you get my drift. Or carpet munching without a carpet, if you prefer that analogy.Anyway, this was not a professional event, with camera crew, director and paid staff. This was just Mom and me, our first time making love (OK, just raw sex) with each other, and if I didn't. “It’s an organ at the top of the neck that houses the vocal folds, mucous membranes that are stretched across the windpipe and which vibrate to modulate the flow of air being expelled. A syrinx, on the other hand, has vibrating membranes that are controlled by minute muscles that line the entire structure. They can even control the left and right valves of the syrinx independently to produce two distinct sounds at the same time.”“So that’s why they sound like parrots?”“Possibly, yes. As for the. D. Oh. we. can't. Do. Ohhh My God!" Mom yelled as I felt my mushroom head lightly enter her forbidden womb.It was too much for both of us. My dick stayed connected as she rocked back and forth and pushed more and more of me into her hot steaming pussy. I pushed myself up and my entire cock sank deep into her succulent snatch."Oh. Fuck. Mom!" I yelled as I felt her body move faster and faster. Mom went from rocking to bobbing. Her pussy went hard down onto my stiff erection as my dick pleaded.
