"Like what you see, kids?" he said, turning towards them.

"Wow! Its big!" Jamie said in awe.

"Oooh! Its got stuff leaking out," Susie said, pointing to the pre-cum dribbling out of the purplish crown.

"That's just the stuff that helps it go inside someone, Susie. Its like the stuff that came out of Jamie and that comes out of you and your mum when you are played with. It makes everything slippery. Feel it."

The little girl hesitatingly put out her finger and touched the end of the man's huge organ. It was bigger than her forearm. Dr Hubbs took hold of her finger and wiped it over the shiny knob.

"Feel how slippery it is?" he said and Susie nodded, her eyes wide as she looked from Jamie to the man, comparing their sizes and getting rather nervous. The doctor let go of her hand and turned towards Jenny. "What about you, Mrs Dodds? You like what you see?" He took hold of himself and pointed it at her. "This'll fill that sweet cunt of your's." He put his hand on her swollen, moist pussy, his fingers fondling the engorged labia. The woman moaned as he pulled them outwards. He stroked her for a moment, his eyes on her, a smile on his face. This was going along exactly as he had fantasised. He let go of her and turned back to the two children.

"My cock is bigger than Jamie's, but his will grow as he gets older. And his balls will get a little bit bigger, too, like mine. You can see all the tubes inside my scrotum. See how they are much more pronounced than in Jamie's, Susie? That's because I have had a lot more sex than Jamie. His will start to look like this when he has sex regularly." He laughed. "Probably from now on, I'd say. He'll want to fuck you and your mum all the time now, I reckon. That right, buddy?" Jamie blushed, as did his mother, but he nodded. He wanted to do it more to his mum, that was for sure. He didn't know about Susie, though.

"Okay, kids. I guess its time I showed you how men and women do it. Right, Jenny?" the doctor said, his hands resting on the young mother's lightly tufted mons. "Ease yourself down to the edge of the table so I can stick my cock in while I'm standing so the kids can watch it easier." He moved around to stand between her legs as she wriggled her nude body down the sweat-damp leather table until her buttocks were on the edge. Dr Hubbs put his hands under her thighs and he pressed them up and outwards, pushing them back over her body so she was opened between her legs and moving her into a more accessable position. His thick penis touched her as he maneuvered her around, its slimy tip leaving a cold trail over her buttocks and groin as it waved around.

Jenny saw her two children looking at her exposed pussy and suddenly realised that instead of her earlier embarrassment, she now found it rather exciting to know they were going to watch the doctor's erect penis enter into her, watch her being impaled on his beautiful organ. In spite of the vulnerable and degraded position Dr Hubbs was putting her into in front of her children, she was incredibly aroused; all she wanted was something inside her ... fingers .... tongue .... dildo ... cock ... just anything to ease the tingling itch that was overwhelming her. Even though Jamie's penis had made her come, it wasn't as big as she really needed to reach complete fulfilment. But the doctor's certainly was. She raised her head to look at it standing so proudly in front of the doctor. He was such a gorgeous hunk of man, Jenny suddenly realised, seeing his powerful, nude body standing at the junction of her thighs; and such a magnificent cock! She caught her breath as the man pressed his glans at her entrance.

"Watch this," the doctor smiled, talking to the two fascinated children. He pulled their mother's labia wide and pressed inwards, his huge glans starting to spread open the woman's tight vaginal entrance. "Lets see if I can go right into your mother's cervix," he said, the thick flared rim of his glans forcing inside her and disappearing from their sight. The two children watched Dr Hubbs length slowly moving inwards, making their mother's sex bulge even more as it forced her wider open, glancing up at their mother's face every few seconds to see her reaction to its invasion. As each inch of the large shaft slid into her, her eyes widened and she kept catching her breath. Jamie reached out and began fondling his mother's breasts, pulling on the hard nipples and kneading her firm mounds. His mother glanced at him and a brief smile of approval came his way before her attention went back to the maleness delving deeply into her body. She felt a sudden pressing at the very base of her belly and the doctor stopped moving......(cont)
