Peter was the twin brother of Sandra's father and at fifty; he looked and behaved remarkably like his brother.
The brothers were an even six feet and had managed to weigh an identical seventy each. Narrow shouldered, silky brown hair tinged with gray swept back across their foreheads and covering their ears, even their mannerisms were alike.
When Sandra walked into her bedroom and picked up the baby in her arms, she could hear Peter moving around in the bathroom.
"That you, Sandy?" he called out.
"Yes. You having your bath?" Sandra answered, sitting down on the bed and bringing out one breast from her blouse to feed it to the infant, who immediately began suckling at it contentedly.
"Yeah. How was the workout?" Peter called out.
"Great."
"What are you doing there?"
"Feeding Robin, what else? You should know it by now."
The bathroom door opened and Peter walked out.
His face wore a grin. Besides that grin, he wasn't wearing anything else.
"And, you little girl, you should know that your uncle loves watching this ritual!"
She laughed, eying his phallus dangling between his legs. "As he always does!" she replied. "I was held up for a while and I know that if this little guy doesn't get his morning dose, he was going to bawl out for the rest of the day."
"And if this little fellow," Peter said, gesturing at his semi-erect cock, "doesn't get his usual dose, he's gonna have to bawl out all alone."
She pressed the baby closer to her breast and grinned. "That fellow never bawls alone. Whenever he wants to cry, he comes running for mama!"
Peter walked to her and stood beside the bed, watching the baby suckle hungrily at her breast. He sank his fingers into Sandra's hair and gripped the back of her head, twisting her face towards him. He thrust his hips out so that his cock head brushed her face.
"So, go ahead, little one," he said.
Even as the baby suckled at her breast, Sandra opened her mouth wide and allowed her uncle to thrust his cock inside. Peter was big in that department; almost seven inches of meat was stuffed in her mouth and she had to stretch her mouth really wide to accommodate him inside.
"Ah, baby, you do that so good," he whispered. "You are always horny, especially after you get back from those workouts!"
Peter began to undulate his hips back and forth, fucking his niece's mouth gently. He would pull his cock out of her mouth completely, allow her to lick the shaft and then push it back into her mouth. Every stroke got a little deeper and deeper until eventually, and as usual, the entire length of his cock disappeared inside her mouth.
"Hmm," Sandra managed to say as she let her tongue sweep the hot flesh of his shaft.
Peter reached down and lifted the cup of the bra covering her other breast. He cupped it, marveling at its tautness and size.
Gently, he squeezed it, delighting in the way that the warm milk jetted onto his palm. He grasped the erect nipple and rubbed it between his thumb and forefinger.
She pulled her head back and looked at him.
"You are really horny, huh?" she asked mischievously, allowing the tip of his cock to rub against her lips as she spoke to him.
"I was inside the bathroom thinking of all those things we did yesterday night and damn! I couldn't help but get harder and harder. I have been waiting up for you baby! For so long!"
She giggled, shifting to one side to allow the baby to continue suckling her breast. She dropped one shoulder back and pulled his on his cock. He let her do it and groaned when she directed the tip of his cock on the nipple that the baby wasn't suckling on.
"Oh Jesus, Sandy, that feels so fucking good I could shoot all over you!" he gasped.
"Wait," she whispered, "the baby's almost through."
She let him squeeze the tit till some milk had dribbled onto his cock and then let her tongue sweep across the throbbing shaft.
He took a step back and watched as his niece rose from the bed and carried the baby back to the crib.
"Fast asleep," she commented, turning around to face him. Her tits were wet with the milk and glistened in the dark of the room.
He was now sitting on the bed, almost at the same spot that she had occupied when feeding the baby. She stepped up to the bed and standing in front of him, she put her hands behind his head, thrust her hips out and pulled his face to her belly.
Immediately, his hands went to the buttons of her jeans and as he nuzzled her t-shirt, he slid off one button after the other. Sandra impatiently pulled her t-shirt up over her head and flipped the dangling bra aside to stand naked in front of her uncle.
He watched her large rosy pink nipples, glistening as they were, now getting harder. He enjoyed watching her getting turned on. She looked so pretty and so sexy, he thought, wondering why that dumb son of a bitch Alex had walked out.
"Tits or cunt?" he asked mockingly, having already pushed her panties down over her ripe thighs, past her long legs till they were lying in a puddle around her. She stepped out of them, kicking them away.
"I'm very hot now, uncle! I need to..."
"Don't say anything, baby. Cunt it is," he chuckled, leaning forward to push his face squarely into her crotch.
