‘Yes! You’re so sexy!’ replied Nick. ‘Can I touch you? Please?’‘No. But I like you looking at me. I like you watching me play with my brea...ts. I’m a horny little bitch and I want you to see how naughty I can be.’I suddenly felt shocked at what I’d said. Where had that come from? I’d said it without thinking, but why? Was I into talking dirty?‘Show me then, naughty girl. Cause I love watching you. It’s making me so horny!’He started masturbating faster. He seemed very excited. I lifted one leg. She squeezed her pussy muscles around his shaft and milked him as he withdrew and drove back in, leaving more and more white froth as a ring around his veiny pole. Her fingertips dug into the flesh of his shoulders, her hot breath blew into his face, her thighs clamped around his hips and her nylon-clad heels bore down into his buttocks. Mark drew his ass back and his cock with it, and pounded back, little specks of sweat and cunt juice flying from their pounding crotches.Mark held his mother's. The first couple of attempts were ragged, because each mind had different rotation speeds, but the third attempt was close, and the fourth apparently flawless. I practiced one more time looking away from the mirror, which I didn't really need, but sight is a hard habit to break. It seemed fine, so I canceled them all then asked Julia to watch.I did it again, and she declared, "It'll knock their socks off."I got her to keep watching while I moved my head a bit, then I tried walking slowly. Not with knowing what he intended to do tomorrow, so he'd suggested the nightcap, certain she would refuse, and now he wanted to be sure she was sleeping when he joined her in bed.Truly, he felt like a cad, but damnit, he doubted that he could endure a session of her amateur sexual calisthenics tonight, which was no reflection at all of his feeling for her; he loved her; there wasn't the slightest doubt in his mind about that... but he needed a woman, a warm-blooded, capable woman who knew how.
