.” My words trail off as I feel my orgasm right there at the very edge of exploding. I grip my chains as I let my mind sink in begging with its sel... not to cum. I beg myself now as Master doesn't let up on me. He works me even faster than He had been. I let myself whine out knowing I was so close but not allowing myself to orgasm. I feel the urge subside as I breathe in deep knowing how close I had been even with how much He didn't let up. He slows down as He sucks my clit out of His mouth He. "How many inches do you think you could take in your mouth... and down your throat, slave?!" I don't know, I don't know!" she yelps somewhat fearfully."Just fucking give me a NUMBER!" I growl, pulling her hair."Ooww! Ten! Ten inches!" Ten inches?! Good God, you really love dick, don't you? You really think you could take that many inches?" "Yeah, I could do it." Have you ever swallowed that many inches before?" N- n- no," she stammers.I grab her by the hair with two hands, getting a nice grip.. Looking up she knew from the almost glazed expression in his eyes what was going to happen. Her son was going to fuck her. Making each other cum as they had was one thing, this was crossing the forbidden line once and for all.“Be sure,” she said to herself, but out loud, “be sure it’s what you want.”Mark clearly didn’t hear. He was lost in a fog of lust and desire, a young man with strength she couldn’t match and a cock so hard and beautiful again she really wanted it inside her.Helen knew. His mother brought the cock head to her moist nether lips and the head into her crevice."UUUnngghh! So good!" Helen purred as she sank down on Steve and tooks her son's dick into her pussy. Steve threw back his head his hips bucked off the bed as he drove his penis into his mother's cunt. The pressure exerted on his cock by her silky walls was amazing.Helen's pussy was wet and tight as she moved up and down on the invading tube of flesh in her pussy. She groaned and leaned down to kiss Steve.
