Thirty minutes later and midnight was approaching. Mary watched Maria Carey perform 'All I Want for Christmas Is You' on the TV and thought about her son. A banner flashed on the screen: 'Happy Christmas everyone' and she looked over at Glyn.
Glyn smiled as Mary rose from her chair and stood in front of him. She turned with her back to him and slowly slipped her gown off her shoulders as she danced to the music. Glyn watched her hips sway to the beat and felt his cock harden. When Mary dropped her gown to reveal she was naked, his cock sprang to a full erection.
"See anything you like?" Asked Mary, looking over her shoulder and gently wiggling her ass at him.
"Mary, you have the most perfect ass and legs."
She turned, moved closer, put her hands on his knees and leaned in and kissed him on the lips.
"Happy Christmas, Glyn", she said as she broke the kiss and sat down beside him.
Glyn's cock throbbed as Mary placed a hand on his thigh. "Happy Christmas, Mary," he replied.
Mary took hold of the tie of his robe and pulled. "Looks like you are ready for your next lesson," she said, as the robe fell open exposing his cock. "Have you ever played with Sandy's pussy?"
"No." He whispered.
"She'll need to be warmed up before you can have sex with her." Mary lifted his hand, took his index finger and traced it down one side of her pussy and up the other side. As she repeated this move, her hips rose and Glyn could see her exposed pussy. Mary moved his hand to her mouth, sucked on his finger then returned it to her pussy. This time he stroked down one side of her labia and up the other side, before moving towards her clit.
"Have you ever seen a lady's clit?" She quietly asked.
"Only in porn," he answered.
"Then that's where the lesson will begin. Get down between my legs."
Even though he had had sex with her less than an hour ago, Glyn still couldn't believe what was happening. Mary opened her legs wide apart and Glyn got down on his knees for a closer look. Mary looked at him staring at her pussy and somehow resisted the urge to grab his head and pull him to her. Instead she opened her pussy lips with one hand and began stroking her pussy with the other.
With a husky voice, she asked "Can you see how wet I'm getting?"
Glyn nodded, not taking his eyes off such a magnificent sight. Mary eased two fingers inside her pussy and moved them in and out. Then she gently moved her glistening fingers to the top of her pussy and revealed her clit. Her body convulsed, her legs closed together and she emitted a low groan "Mmmmm".
Slowly, she moved her legs apart and exposed her clit to him again. Softly she spoke: "This little bud is my clit. It's the most sensitive part of a woman's body. Don't press too hard, but rub it gently in a circular motion. Give me your hand."
Glyn moved his hand towards her pussy, staring, as if in a hypnotic state. Mary took his index finger and slid it inside her. He felt the heat and moisture and looked up when Mary moaned with pleasure. Her eyes were closed and her head gently rolled backwards onto the sofa. She moved his finger up to her clit and began to rub it.
Glyn could feel the heat from her body on his face and the scent of her sex was intoxicating. She released his hand and he continued rubbing her clit. Using his other hand, she moaned and gasped for air when he slid two fingers inside her.
"That's it." She uttered. "Right there. Keep doing that. Mmmmm," she groaned.
The moist evidence of her arousal coated his fingers. Glyn was mesmerized. He continued massaging her clit and gently moving his fingers in and out of her pussy. Watching her head sway from side to side and her breasts move up and down in time with her pussy contractions, was more than he believed possible.
Mary moaned; he looked up to see her pinch a nipple and let out a little squeal. Her breathing shortened and she arched her back off the sofa. Her legs snapped together and clamped his hand to her pussy.
"Uh, uh, uh, uh, uh, uh, uh, I'm gonna come. I'm gonna come. Ahhhhhhh." She moaned, then her body went limp
After a few deep breaths to return some oxygen to her brain, Mary opened her eyes and looked at Glyn with his hand still inside her pussy. His face was red, his eyes wide open and his mouth ajar. A look of complete astonishment. "Christ." She thought. "If he can do that with his fingers, what's he gonna do with that cock?"
Mary opened her legs and John removed his hand. "Sorry." She said. "I was taking care of my needs before yours."
Glyn laughed. "Sorry! You've got nothing to be sorry for. You just let me make you come."
She sat up and reached out for his hand, pulled him towards her and kissed his lips. "Did you like that?" She whispered into his ear.
"That was the most exciting thing I have ever seen."
"Good. I think I'm ready for you now." She said, looking at his cock bouncing against his firm stomach. "This next part, you will have to teach Sandy what to do, so it's important you remember it."
Glyn laughed again. "I don't think there's any danger of me not remembering this, Mom. Sorry, Mary."
Mary laughed. "Me neither," she said, as she positioned her hips over the edge of the sofa. "Put your hand around your cock and just insert your crown into my pussy, then stop."
Glyn knelt between her legs, looked down at her red lips and pushed the head of his cock into her pussy. The heat sensation caused a shockwave of lust to ripple through his body.
