The next morning around 8.00 a.m. Dr. Wood entered the house pulling the door closed behind her. Again, she was quiet, again she didn't want to disturb Kelly and Jason. She paused when she heard a familiar sound coming from behind the kitchen door, which was not quite closed. She carefully approached the door, peeking in. She observed them, without revealing her presence. Kelly was leaning over the kitchen sink, facing the wall, her weight resting on her arms. Dr. Wood could see clearly how Jason grabbed her bare breasts from behind and squeezed and kneaded them. He used his thumbs and forefingers to circle and pinch her erect nipples.
Kelly moaned and turned her head to him. "Ahh... Jason, no... What are you doing, honey? What do you want?" Kelly asked, like she didn't know what he wanted to do to her. She could feel his big, hard cock against her back.
"Shhhhh... I want to fuck you right now, mom!" Jason said in a low, husky voice, ignoring her protests. There was no dilemma. He wanted sex! He wanted to cum!
"Ohhh, baby, you just finished ... you came in me already," Kelly protested helplessly.
"You're gorgeous, mom... and so sexy. I'm horny, mom... I can't wait, I want you from behind on all fours!" Jason insisted. At the same time, he spread his mom's legs apart and drove his cock in while she was bent over. Then he pushed harder and his cock filled her, making her all too aware of his rigid length and girth.
"Ahh... ohhh... you feel so good, baby. Your cock is so good! But you need to wait for me to finish washing the dishes," Kelly begged as her body unexpectedly began to shudder and her pussy gripped and contracted around his cock. Also, Dr. Wood noticed as Kelly simultaneously raised her ass in the air and spread her legs wider, willingly getting into a better position for Jacob.
"I can't wait, mom. You're so tight and silky. And so wet!" Jason answered and continued to penetrate deeper into his hot mom from behind.
What a pleasure it was for Dr. Wood to see Kelly's great huge boobs swaying rhythmically as her son mercilessly sank deeper and deeper into her tight, wet and puffy pussy. Finally, Dr. Wood entered the kitchen and softly said, "Kelly, I think that it's better for you to please him first! The dishes can wait, but his hormones can't."
"But he just finished not 30 minutes ago," Kelly tried to explain.
"Has he already fucked you, this morning?" Dr. Wood asked in surprise, simultaneously vividly remembering yesterday's delightful penetration sessions.
Red-faced, Kelly looked back toward Dr. Wood and spoke softly, "Ahhh... yes... He came to my bed around 7 a.m., naked, waking me. Before I could say anything, he was under the covers softly touching and caressing me! Soon he set me on all fours... and it felt so good to get fucked from behind!"
Kelly paused, she was breathing heavily, and her eyes were glazed over with passion as Jason started to pound into her harder.
"Jason, is this true?" Dr. Wood now focused on Jason.
"Yes," Jason confirmed, "I was so horny all night, thinking about my hot mom, that I couldn't wait to fuck her again."
"Oh, Jason, I understand your needs pretty well. It is important for you to have orgasms, and the more frequent and more intense, the better, " Dr. Wood said with understanding. "Kelly, Jason mustn't wait for his ejaculation all night. So, it is necessary for Jason to sleep in your bed, so he can fuck you at any moment when he needs. I guess that is all right to you? What do you think?"
"But... Ahh yes... I know... He is extremely horney... And I understand his needs for satisfying his sexual urges and... ahhh... I will give him all that he wants," Kelly answered gasping for breath. "Ohhh... Yes, honey! Fuck me! Fuck your mommy! I need it so, so bad!"
Dr. Wood smiled as Kelly moaned and threw her head back in total surrender to Jason's sexual attack. She had never seen any woman enjoy fucking this much, obviously the hot mom experienced it with her full body, as though all of her was fucking, not just her pussy.
"I noticed your mom catching the incredible appetite for your big young cock," Dr. Wood observed and then asked Kelly provocatively, "Doesn't that big cock feel good?"
"Ohhh...Yes... His cock feels soooo damn good! Don't stop! Don't stop, please!" Kelly was so high on sexual lust that she just blurted out her reply.
Jason pushed his long cock in further until he was sure that he was pressing up against his mom's cervix. He knew that was what his hot mom wanted. He felt the resistance of her cervical opening dilating before the pressure of his cock head. He gripped his mom's hips firmly and pushed in even further. He listened to her groan for a few moments as her cervical opening began to envelop his glans!
"Ohh ohh ohhh... that's it! Yesss... I'm coming!" Kelly moaned, her whole body trembled and hummed, as her climax crashing over her.
Jason gripped her ass cheeks and pulled her open, pressing his cock deep into her. Now he got a lewd sight of his mom's butthole and he witnessed the unbridled and provocative spasm of his mom's asshole during the peak of her orgasmic release. Dr. Wood waited there for some time after Kelly finally calmed down from the fierce huge orgasm she'd just experienced then suggested, "Please, come with me into mom's bedroom. I want to show you something new."
With a sensuous gleam in her eyes, Kelly leaned forward and held her hands against the kitchen sink as Jason withdrew. There was an audible slurping sound as her pussy released his huge cock, then they followed Dr. Wood obediently out through the door and up the stairs with their minds full of the anticipation that comes from knowing something new is about to happen. They didn't know quite what, but they knew it was exciting.
When they entered Kelly's bedroom, Dr. Wood said, "Mommy, I know Jason could last longer after his first morning release. So, I think it's time he is fucking you in missionary pose. Since he will sleep with you in your bed from now on, he needs to know more than just two or three poses. Please, lay on your back and spread your legs."
Dr. Wood had expected Kelly to protest, but instead Kelly nodded and blushed, prettily as always.
"I'm so embarrassed," Kelly added in a low soft voice, but willingly lay down with her legs wide spread, making herself available to Jason. When she was on her back, her natural big breasts sank back into her chest somewhat, but still stuck out significantly from the side and front. Her nipples, erect and hard, rose and fell with her breaths. Dr. Wood slowly grabbed both Kelly's thighs and pulled her knees against her chest to open her up to the maximum extent. Jason, seeing that sight, gasped with excitement and joy. It was something he will never forget. In that wide-open, vulnerable position, his mom's protruding wet pussy lips were so long and thick. The inner lips of her vagina pulsated with need, aching and creaming from her arousal. Her wonderfully sensitive clit was so big and fat and proudly stood out.
"Jason, if you wake up during the night with an erection and new energy to fuck your mom again, you can't expect your sleepy mom to immediately mount and ride you or set herself on her hands and knees in a doggy position. That's why it's important to get to know new poses, like missionary. When you wake up, just turn your mom on her back in this pose, if she isn't already sleeping on her back, then move between her legs, slip your cock into your mom and let the pleasure of you fucking her wake her up. Okay?"
"What are you saying? That I can fuck my mom while she is asleep?" Jason asked disbelievingly.
"Absolutely. You can start having sex with your mom while she is still asleep. And don't worry, your mom will not be angry if she wakes up during the night to find you fucking her madly. Will you, hottie?" Dr. Wood asked Kelly teasingly as she began to stroke up and down over Kelly's breast, each time brushing her erect nipple.
"Ahhh... no... I will not be angry at all. Well, I know Jason has overriding sexual urges and cravings... And I only want to please and truly satisfy his sexual longings," Kelly answered breathing heavily. Apparently, she had forgotten the intended, original goal of their therapy!
"Jason, you must be proud of your mom! This is what good mommy's do for her endowed and horny boys. Also, don't be the least bit surprised if you wake up during the wee hours and discover that your horny mom is sucking your cock. You know how she dearly loves your big fat cock." Dr. Wood added.
Jason couldn't believe what Dr. Wood said. Mad with lust at the amazing sight of his mom's hot body and Dr. Wood's words, Jason climbed in a rush onto the bed next to his mom and began caressing her long firm leg up over her stomach and cupping her huge breasts.
"Ahh... ohhh... yesss... fuck your mom!" Kelly whispered helplessly.
"Jason, hold and spread your mom's legs with your hands and position yourself between them," Dr. Wood instructed him and simultaneously guided the tip of his huge cock to Kelly's entrance.
Kelly was breathing hard, her mouth wide open, and her hips unambiguously rose to meet his erection. She moaned as she felt Jason's cock head again against her swollen pussy lips. Jason spread his mom's long sexy legs even more and impatiently entered her. Her creamy pussy had readily accepted his full length and girth, and the stimulation of his thrusting felt so good. A low, sensuous "Aaahhh!" escaped Kelly's mouth. He felt his mom's arms around his butt, and he began to pump harder.
"Easy now," Dr. Wood warned him.
