PROBLEM WITH MARK

The Stevens family consists of three members: father Steven, mother Marry and son Mark.

Steven 50 years old, largely built, with thick black-gray hair and dark eyes. He is open-minded man, faithful to his wife Marry, a typical example of a family man who spends all his free time in the company of his family. He and Marry have been married for 20 years and after two years of marriage, their son Mark was born. Steven is a faithful man, it never occurred to him to cheat on his Marry, even though he had more than one opportunity to do so.

Marry is younger than Steven, she is 43 years old. She is a short woman, and could not be called a beauty. She is a fat lady, the extra weight is mostly distributed in her legs, hips and extremely large buttocks that are sticking from her back. Her hips are wide and her legs are very thick. Her breasts are not particularly large, they are of medium size and slightly drooping. They end in large alveoles and large, always hard nipples. Marry is a hardworking, dedicated woman faithful to her husband and full of love for her 18-year-old son Mark.

Mark is a big, strong and healthy 18-year-old and the only son of Steven and Marry. His parents raised him extremely well, and he was an obedient and decent young man. Since Mark's birth was difficult, Marry barely survived it, the couple somehow couldn't decide to have another child.

The Stevens's are a happy family living in a spacious apartment on the outskirts of the city, they are in good health and economically well-off. Steven is a lawyer employed in the local civil service, while Marry is employed as a secretary in a large local company.

Steven and Marry's sex life can be characterized as typical for their 20 years of marriage. They make love 1 to 2 times a week, mostly in one of the typical positions - most often missionary, and sometimes Marry would be on top. Since Steven's penis is not particularly large - about 6 inches, they would rarely do it in a doggy position. Because of Marry's big ass, Steven couldn't go deep enough into Marry's vagina. They never tried oral or anal sex, although in their conversations lying naked in bed they never avoided any topics related to sex. Simply, they have both always loved classic sex.

Mark, at 18, was still a virgin. He had no experience with the girls, and in all those years a terrible hormonal flame burned in him. Mark's 7 inches long penis was hard practically all day (and most of the night). Since he didn't have many friends, he spent most of the time in the house and the only female person in front of his eyes was his mother Marry. Because of this, he developed a rather serious case of Oedipus syndrome and lust for big women with big butts.

Since they lived in a relatively small apartment, Mark had the opportunity to see Marry completely or partially naked on many occasions. In the house, Marry always took care to be decently dressed in front of her son. She wore T-shirts and knee-length skirts, and during the hot summer months she would wear short shorts which would make her thick legs visible and her big buttocks very pronounced. Clearly, Mark's favorite time of year was summer.

Several times he accidentally entered the room while Marry was changing and had the opportunity to see her bare breasts, and sometimes her naked huge ass and hairy pussy.

Marry noticed almost constant bumps in Mark's underpants and suspicious stains on his underpants when she put them in the washing machine, but she attributed that to the hormones of the 18-year-old teenager. Lately, however, she had been noticing his gazes directed more and more at her bare legs, chest, and crotch. At the beginning, she didn't pay much attention to that, but she started to think about everything more seriously when she found her big panties wet and sticky on two occasions while washing her clothes. It was obvious that the part of the panties that clung to her pussy was wet with male semen. It became clear to Marry that Mark was taking her used panties and jerking off into them. Although she had heard that young boys do such things at his age, she was still shocked and surprised.

Mark was a well-mannered young man who would never take a direct step when it came to lust for his mother, Marry knew that. For this reason she knew that her only son was suffering greatly, because Mark knew that his mother would never consent to any sexual activity with him out of respect and fidelity to his father. On the other hand, Mark truly loved his mother. He didn't just want to sleep with her, he wanted to make love to her, hug and kiss her.

Marry became increasingly awkward about Mark's lustful looks, and kept thinking about Mark. She decided to talk about this problem with Steven. One Saturday night, after the usual Saturday missionary sex with Steven, while lying naked in embrace, Marry began a conversation.

"Steven, our Mark is a big boy." she said at the beginning.

"Yes, he just grew up and developed into a real young man." Steven replied.

"Steven, I think he has fantasies about me. He keeps hanging around me and staring at me. A couple of times he burst into the room while I was changing, I think he did it on purpose and not accidentally as he said. A couple of times I found cum in my used panties." she said worriedly. Steven was silent for a moment.

"Are you sure?" he asked.

"Yes." she replied. "I'm worried, Steven. Mark is a quiet guy. I'm afraid for his mental health. Why would he be attracted his old and fat mother?"

"Yes, that's worrying." said Steven, "I should talk to him."

The next day, Steven invited Mark for a face-to-face conversation. He asked him a couple of questions about the girls from the school and the neighborhood, to which Mark just shyly lowered his head and replied that there was not a single girl that would interest him.

"What kind of girls do you love, son?" Steven asked. Mark lowered his head, all red with shame.

After a few seconds of silence, he replied quietly, "Dad ... I ... somehow I like older women."

Steven added with a smile on his face: "... and a little bigger ... like your mother?"

Mark jerked abruptly, frightened. "... I ..."

"Don't be afraid, Mark, I guess that's normal. Your mother is always in front of your eyes. You should hang out with girls your age, Mark." added Steven.

Mark just shrugged. "But Dad, I'm not interested in girls my age at all."

Steven placed his hand on his son's shoulder. "You should try, son. Believe me, young girls are much better than your big-ass mom" Steven winked, letting it be known that this 'big-ass' was meant as a joke.

After this conversation, Steven and Marry hoped that Mark would turn to younger girls. However, nothing in Mark's behavior changed. He became a little more careful, making sure Marry didn't notice his looks. But he could not hide his lust entierly.

After a few months, a hot summer came and Marry and Steven talked about Mark in bed again.

"Steven, the situation with Mark hasn't changed much. I think I noticed him peeking through the keyhole yesterday while I was undressing. I don't know what to do." she said.

"Do you think this will stop?" he asked Marry.

"I doubt it. I don't know what to do, I'm very embarrassed. Especially when I'm home alone with him. I know he would never make a move towards me, he's too well-mannered for that. But it's hard for me to watch him suffer. I'm afraid for him." she replied, recalling the events of Mark's childhood when he would grieve for days if he didn't get a toy or if one of his wishes wasn't fulfilled. Mark never insisted on his wishes, he only mourned deep inside for not fulfilling them.

"Hah, so just let him sleep with you. Maybe then it would pass." Steven laughed jokingly.

It wasn't funny to Marry. "What are you talking about!? To have sex with my own son! You're so rude!"

"I'm kidding, Marry. Don't be mad." he said softly. After that, they went to bed without any idea of what to do next.

The next day, Marry and Steven had been thing about the last night conversation. What if Mark is left with a permanent psychological problem due to lust for his own mother? What if it grows into a lifelong problem? On the other hand, if he slept with Marry, he might have lost his desire for her. And, again, maybe the situation will get worse. What to do about it?

The next night they raised Mark question again. Steven started first, with a cautious question, "I've been thinking a little bit about Mark. Have you thought about it?"

Marry replied, "Yes. I've been thinking about it all day."

"What do you think, if he might sleep with you once, would that desire pass him by or would it be even worse?" Steven said cautiously, waiting for an angry answer from Marry.

However, Marry's response was quiet and worried. "I don't know Steven. How can I sleep with my own son? And on the other hand, will that help him?"

"Let's consider the situation. If we were sure he would get through it, would you agree to sleep with him?" Steven asked cautiously.

"Steven, that's our son. How can I sleep with him! But, on the other hand, what if he is left with psychological consequences because of this lust?" Marry said with tears in her eyes. "What should we do, Steven? I would do anything for Mark, but sleep with him ..."

"I wouldn't mind Mark sleeping with you if it helped with this problem. Of course, I'm not happy about it at all. But if it helps at all, I agree. The decision is yours after all." said Steven gravely. After that, there was a silence that lasted for a few minutes.

Marry said with tears in her eyes, "I would do anything for him, even sleep with him, if he would give any chance for the lust to finally pass him by."

"Good." Steven replied, somewhat altered. "We'll try, although I don't like it either. What do you think, how do we do it? Maybe I'll go somewhere for a day. It would be very strange for me to be in the house while you're doing it."

"Yes. I, I don't know." Marry answered uncertainly. "Maybe, as you said, to go somewhere over the weekend. But Steven, this must not continue afterwards!"

"I'll talk to Mark. My coworkers called me to go fishing this weekend. I thought I'd turn them down, but if we will do this thing I'll accept. Does this weekend suit you? I don't think you're going to get your period or anything?" said Steven.

"This weekend it's OK. He'll probably want me to do it with him multiple times during the day." said Marry uncertainly. She had been using birth control pills for years, so there was no danger of pregnancy. She was scared and not sure how to behave.

"Okay. Then we made a deal. We didn't ask Mark, but I'm sure he wouldn't mind." Steven laughed, trying to break up the heavy atmosphere that reigned between the worried spouses. "Nothing can happen between you two after this weekend. Agreed?" said Steven, hoping their plan would work. He couldn't even imagine what would happen if it failed. Will the situation get worse than it is now?

"I agree." Marry answered sadly. "You talk to him. Let him know you agree, and let him know that this is only for one day. Steven, I hope this works, because otherwise I won't be able to live with myself." tears streamed down Marry's cheeks.

"It'll be all right." Steven said. "It will pass him by. At that age, young men get to know the world and want to try everything. When it's over, he'll chase girls his age. You'll see."

With heavy thoughts, Marry and Steven couldn't sleep until late into the night.

The next day, Steven again invited Mark for a face-to-face conversation. Mark was more scared this time than last time. What does Dad want now?

Steven began: "Mark, my mother told me that you are still watching her lustfully, even if you peeked through the keyhole while she was changing. Is that true?"

Mark died of fear, "... Dad, I ..." he couldn't finish the sentence, he started shaking with fear.

"What's going on, son? Tell me, don't be afraid. You can tell me everything, whatever it is. Why are you so fascinated by your own mother?" Steven said lightly.

Mark started crying. "I don't know, Dad. There's no way I can get her out of my mind."

"Mark, do you want to sleep with your mother?" Steven said calmly.

"Yeah. That's all I think about, Dad. About making love to her." said Mark, all in tears. "I can't get it out of my head, whatever I do ..."

"Okay son, I understand. I'd like to help you. It's really hard for Mom and me to watch you unhappy like this. We want to help you." Steven calmed him down.

"How can you help me! No one can help me!!" continued the weeping Mark.

"Tell me, would that desire of yours calm down if you slept with your mom one night?" Steven asked calmly.

Mark froze. "Slept? You mean, next to her in bed?" he asked quietly.

"Yes. I would be out of the apartment that day. I would leave you together, and come back home the next day." Steven replied.

Mark's heart stopped for a moment. Did Dad think I was sleeping on a pillow next to Mom? Impossible that he thought I was sleeping with her in the sense of having sex with her! How would Dad or Mom agree to that? No, she probably thinks I'm sleeping in the same bed with her. But why is he saying he will leave the apartment? Mark couldn't say anything, so he kept silent and silently watched his father, who became increasingly uncomfortable with the conversation.

"But certain rules must be set. Rule number 1: everything you do must have your mother's consent. Nothing must happen against her will. She agreed to have sex with you, but the way you do it must be in accordance with her will. Is rule number 1 clear?" Steven asked.

Mark almost got a heart attack. He said 'she agreed to have sex with you'!! He agrees for me to have sex with my mom while he is out of the apartment!! It took Mark a few seconds to open his mouth.

He barely uttered, "... clear ..." quietly.

"Rule number 2: after your day together, all kinds of sexual thoughts and activities stop. You two will never have sex again, and I expect you to get rid of your desire for your mother afterwards. I believe that will be enough to get rid of your obsession with mom. Is rule number 2 clear?" Steven asked.

"Yes." Mark replied quietly.

"OK, then we all agreed. That would happen this weekend. On Friday night I go fishing with colleagues from work and come back on Sunday afternoon. During this time mom is yours. You'll have two nights and a whole day to spend with her. You have to abide by rule number 1. The way you do it is a matter of agreement between two of you, but mom has the last word. I know you'll respect it, you've always been a boy who respected your parents' wishes." said Steven.

"But .. but what does mom say about this?" Mark asked shyly.

"I talked to her, she's afraid for your health. She's ready to make love to you, even though you're her son, if that will help you get over that obsession. That's why I expect you to fully respect her. She sacrifices the most. So I ask you, can I expect you to get those obsessions out of your head after the weekend? Mom will fulfill your wish, but neither she nor I would want the situation to get worse later than it is now." Steven asked seriously.

"Yeah I think I'll be better after the weekend. I promise I'll obey to my mom's wishes over the weekend. I promise I won't stalk my mom again after the weekend." said Mark a little bolder.

"OK Mark, agreed. Friday's in two days, get ready." said Steven and left the room.

Mark remained stiff. His heart was pounding like crazy. What happened? Is it possible that his own father told him that he and his mother would have sex, for two nights and a whole day! How is that possible! How did Dad agree to practically leave his wife to another man? And not to any man, but to his only son! How mom agreed to something like that? Mark was confused. He pinched himself a couple of times to make sure he wasn't dreaming. After a few minutes he became fully aware of the situation: he would finally have sex with Marry! He will make love to the woman he has been dreaming about all his adult life! On Friday night he will hug her and kiss her with the kisses of a lover! He will be one with her! He will love her! And in the end, he will fuck her! His cock will be between her legs, in her womb! The same womb from which he came out 18 years ago! He probably wouldn't be able to fill her with his semen, Mom would certainly ask him to wear a condom all the time, but Mark didn't care. 'My dick will be in her cunt!!'.

As all these thoughts ran through his head, his cock was so swollen that he thought it was going to explode. Unable to reach the bathroom to relieve himself, he came in his pants as he got up from his chair. "I'll finally have her!" it went through his head once more.

The following days were very strange for all the members of the Stevens family. Steven was a little quiet, he wondered if he had done the right thing, but he didn't change his mind.

Mark was terribly upset. Whenever he met Marry he would look down and leave the room. He jerked off 6-7 times a day because he could not calm his erection. He was stiff all the time.

Conflicting thoughts rolled through Tanya's head. She would walk away as soon as possible when she found herself in the same room with Mark. She just didn't know how it would all go and what to expect on Friday.

Friday has finally come. Around 17:00, Marry and Steven returned from work in a family car. Mark was in the apartment all the time. After lunch, Steven was called by colleagues from work and they agreed to pick him up at 20:00. Steven is preparing for a two-day leave. Marry was sitting in the bedroom on the verge of tears.

Before leaving, Steven entered the bedroom. "Just be brave, love. Everything will be fine. Mark is a good boy. Everything will be fine. Don't be afraid." said Steven putting his hands on her shoulders.

"I don't know what to do when you leave." Marry cried.

"Don't be afraid. You set the boundaries. You can use our bed, I won't mind." he kissed her gently on the forehead. "Just be brave." he said softly and left the house.

After seeing Steven off, Marry went to Mark's room. Mark sat at the table and looked at the computer.

Marry opened the door and, not entering the room, she said quietly, "Mark, come to the bedroom at 22:00." Then she closed the door and went to the bedroom.

It was 10 p.m. Mark walked toward the bedroom on shaky legs. His penis was stiff as a wooden board, though he jerked off in the toilet less than an hour ago. He was wearing a plain white T-shirt and shorts.

He reached the bedroom door and knocked.

"Come in." heard from the other side.

He came in. Marry was sitting on the double bed. She was in a knee-length nightgown. Her thick lower legs were visible under her nightgown. She stared at the floor, embarrassed to look up. Mark just stood motionless, not knowing what to do. Marry got up and took off her nightgown over her head. She was standing in front of Mark in white panties and a white bra. She reached for her back and unbuttoned the bra that had fallen to the floor. Mother's breasts appeared in front of Mark, with large round nipples. Mark just stared motionless.

Then Marry slipped her thumbs behind the elastic of her panties and gently lowered them to the floor. Her pussy was very hairy. Marry never shaved or shortened her pussy hair (except, of course, the bikini area she shaved). Mark looked down and stared at the black triangle of his wet dreams. Mom's pussy was wonderful. Beneath the hair, thick outer lips could be seen in the lower part. Mark's erection became painful at this point.

Marry turned and climbed on the double bed. As she did so her huge buttocks moved like two mountains. Mark watched without a word. She lay down on her side of the bed and covered herself with the quilt she had prepared for this night. Even though it was a summer night, she expected to be naked all the time, so she put on quilts instead of sheets. She looked at Mark."Take off your clothes and come." she said softly.

Mark seemed to wince from his trance. He quickly took off his T-shirt first, then his shorts. When he took off his shorts, a large hard cock popped out. 'He's bigger than his father,' Marry thought as her son climbed on the bed and covered himself with a quilt.

They lay facing each other for a few seconds and looked at each other. Mark was on his left side, and Marry on his right.

Marry was the first to speak: "Do you want to be on top?"

"I'd like to ... I'd like to hug you." Mark stammered and approached his mother.

He swung his right arm over Marry and stroked her upper back. Marry swung her left arm over his back. They approached each other and their bodies touched. Marry's tits merged with Mark's breasts, Mark's cock was pressed against Marry's stomach. Mark's balls touched the hairs of Marry's pussy.

"May I kiss you?" Mark asked.

"Yes." Marry replied. Mark brought his lips to Marry's and kissed her gently on the lips.

Marry responded to his kiss by pressing her lips to his. She was surprised. Seeing his stiffened cock when he took off his shorts, she thought he would immediately climb on her and try to drive it into her womb. She was already preparing to stop him, to avoid rudeness. She didn't expect hugs and kisses, she just expected raw lust.

They kissed for a few minutes, caressing each other's backs. Mark was overjoyed, and Marry completely relaxed. She couldn't help but enjoy these outpourings of her son's tenderness.

When their lips parted, she spoke. "I didn't expect this. I expected you to be a little ... rougher."

"Mom, one thing you always have to know. I love you. I've always wanted to be in your arms. To love and caress you. Just like now. Not just raw sex." he said softly.

They continued kissing for a few more minutes and then Marry felt Mark's cock move on her stomach, leaving a damp mark on her skin.

"Come." she said softly turning on her back.

She spread her thick legs and bent her knees to receive her son's body between them. Mark moved and lay between her spread legs. He lowered his body lightly on hers. His penis was resting on the bottom of his pussy. When he lowered his weight on her, his breasts came in contact with her tits again, and his cock fell with its length between the outer lips of her pussy. Cock head was crushed between their stomachs. Their lips met again in a passionate kiss. This time, their tongues intertwined in a love game. Mark started to move his 7 inch long cock along Marry's lips. Marry was excited by these outpourings of her son's love, and her pussy got quite wet. She was ready to receive her son's dick.

"Enter me, baby." she said softly between the two kisses. He was surprised. He expected Marry to ask her to put on a condom. He didn't expect to be invited to put his cock into her unprotected pussy.

"But Mom, what if you get pregnant?" he asked naively. She smiled.

"Don't be afraid, I'm on the pill." Then she slipped her hand between the two of them took a hold of his dick somewhere around the middle. She pointed it at the entrance to her pussy.

"Push slowly." she said. "Go easy, it's big."

Mark slowly started pushing his hard cock into his mother's pussy. He entered slowly, first the head and then the body of the dick. The pussy spread slowly to receive its guest. Marry felt immense satisfaction. Her son's dick was the second dick that ever entered her womb. And it was much thicker than Steven's. The pussy was quite moist, so the resistance was not too great. She felt pure pleasure, earlier kisses and caresses made Marry forget that she was lying in bed with her own son. That the same dick that she gave birth to herself 18 years ago penetrates her like a spear. Mark was now her lover, not her son.

He rested his elbows on the bed. Her thick thighs pressed against his hips, and his hard dick was driven all the way into the hole he had dreamed of for years. Mark was in heaven. He pulled it out halfway, then pushed again slowly all the way in. He repeated it two more times, and he couldn't take it anymore.

A lightning bolt of pleasure flashed from the head of his cock, down his back. He started to cum. Even though he already came 3 times that day, semen dripped from him like from a fountain. He was stabbed in the mother all the way, firing one after another 6 long ropes of cum into Marry's womb. Soon, it was over.

He lay down on his mother softly said "Sorry Mom. I couldn't hold it. I've been dreaming about this since I got my erection for the first time. I'm surprised I didn't cum even before I pushed it into you."

"Don't worry, my love. It's all right. We're doing all this for you, not for me. Although I have to admit I enjoy your company." Marry replied, stroking her son's hair.

"It'll be hard again in a minute. I'll do anything to make you enjoy it as much as I do." he said kissing the space between her breasts and then taking her left nipple into his mouth.

He gently sucked and licked her nipple, to his mother's great pleasure. He then moved on to another nipple. During that time, his cock softened, still rammed all the way into her pussy. But after only 5 minutes, he was hard as a rock again.

He started coming in and out of his mother's womb again.

This time it all took much longer, over 20 minutes. Mark was very gentle. He went in and out slowly. He started stroking her huge left ass cheek with his right hand. The skin on her ass was white as snow and very soft. A large amount of fat on his ass cheek twisted under his caresses, but her ass was still pretty firm. Mark's left hand rested on the bed. He was constantly changing the angle at which he pushed into his mother. This caused his cock to enter her vagina at various angles, thus putting pressure on various parts of the walls of it with each penetration. This caused indescribable pleasures to Marry.

She enjoyed it immensely. She did not expect such a development. She expected him to lie her on her back, spread her legs. That her own son, driven by unbridled lust, would ride her like a mare. That he would fuck her recklessly, wanting to satisfy his insatiable hormone-induced mating needs. She expected that her own son would not treat her at all as a mother, but as a female in which he wanted to empty the contents of his balls.

However, bed with her was a real young lover, gentle and caring, whose goal is not only to satisfy his low incestuous needs, but also to make her happy.

After 20 minutes of wonderful lovemaking, they both approached orgasm. Experienced after many years of missionary sex with Steven, Marry was able to coordinate the movements of her pelvis with the movements of the penis that penetrated her in order to meet the time of her orgasm with her son's. Mark started pounding his dick hard into Marry's pussy. He felt the climax approaching. The bed shook and creaked under their movements. The quilt fell from their bodies, they were stark naked in the middle of the bed, joined in the forbidden union of mother and son. The sounds of skin-to-skin flaps was filling the rook while Mark's stomach was pounding into the fat-covered Marry's stomach.

Marry let out muffled screams as her son slammed into her with all his might, "Ah! Ah! Ah! Oh God! Ah! Ah! Ah!".

At one point, Mark stiffened and pushed his dick all the way into Marry's pussy. He started to shoot hot semen into his mother's womb. This time it was different, the walls of Marry's vagina alternately twitched and relaxed - Marry experienced one of the most intense orgasms in her life.

"Oh God! Oh God! Son, son, son! Mark! My son! Aaaahhh!" she screamed, bending her head back.

Mark, cumming like never before in his life, also let out cries of pleasure.

"Mom! Oh mom! I'm cumming! Oh mom! I love you! Aaaahhhh!!"

After the last drops of his cum came out of the top of his dick, Mark relaxed. They kissed and hugged for another 10 minutes. Then Mark got off his mother and lay on her right side. They hugged and exchanged passionate kisses.

"You're finally mine, Mom. If you only knew how long I've been imagining this day." he said looking her in the eye.

"But Mark, we are mother and son. This is not right. Although it feels wonderful, this is still incest. A mother should not share a bed with her son. Especially not a double bed on which that same son was conceived. This should not have been happening. It's not fair to your father." there was a trace of resentment and remorse in her words.

"Mom, you shouldn't regret this night. It's the most beautiful night of my life. Even Dad agrees, you didn't cheat on him in any way." he said, kissing her.

"My son grew up to be a real man." she looked at him lovingly and returned the kiss.

After 20 minutes of hugging and kissing, he was hard again. W

hen she felt his hardness on her leg, she said, "Again! You seem to be able to do this all night." she laughed.

"I could be with you for 7 nights non-stop!" he said, trying to climb on her again.

"Wait, let me be up this time." she said.

The obedient son immediately obeyed his fat mother and lay on his back. A hard cock was pointing into the air like a spear. Marry put her thick left leg over him, took his dick and set it at the entrance of her pussy. She lowered slowly on him. The cock entered her easily, because her pussy was already well lubricated, and full of his semen from the previous two ejaculations. She began to ride him slowly.

"Ah. Ah. Ah." she let out light sighs.

Mark enjoyed the sight of his mother's large, broad, fat body. For most young men, that body would not be attractive. The legs were very thick, although they were not covered with cellulite. The rolls of fat moved on her stomach, although her stomach was small in relation to the width of her hips and the thickness of her legs. Two huge buttocks spilled over at Mark's legs. He felt them in the middle of his thighs as she rode him. Her upper arms were covered with fat.

But for Mark, this was the most beautiful body in the whole world. Nothing could replace the touch of his hands on his mother's soft, fat-covered hips. Nor the touch of her soft tits he kneaded as she rode him.

"Mom, I love you! I want to be in you forever. I don't want my cock never to get out of your womb. I love you!" he said in ecstasy.

"Son, no one can love you more than your mother. You are a part of me, you came out of me. And now you have returned to me, with one part of your body." she said intoxicated with sexual fervor.

"And that is not a small part!" she laughed alluding to the 7 inches of pulsating flesh piercing through her womb trying to deliver its fertile juice into her feminine depths.

After half an hour of slow, sensual riding, they both had an orgasm together again. They lay down next to each other, covered themselves with a quilt that they lifted from the floor and fell asleep, happy and satisfied. From Marry's pussy wet semen was pouring, the product of 3 wonderful orgasms that her only son had.

Marry woke up first, around 10 in the morning. Her body was sore from last night's activities. Her pussy was a little red, and the cum on her vaginal lips and on her hairy pussy made her itch. Mark slept next to her with a satisfied smile on his face. She kissed him gently on the forehead, careful not to wake him. Her young lover deserved a break after last night's activities. She got up and slowly went to the bathroom. She went into the shower and washed the sweaty body with warm water, cleaning the cum from her legs and pussy. As she took a shower she thought 'how much sperm just came out of my boy! It could fertilize 10 women. Thank God for birth control pills.'

Wrapped in a towel, she went to the kitchen and began preparing the breakfast. She was sure they would need a lot of energy. The long day and night are before them. And knowing her son's desire and energy, she was sure that they would be very active during that time.

As she scrambled the eggs, she didn't hear Mark's footsteps as he crept up from behind her because of the sound of the shaker. He hugged her from behind, wrapped his arms around her breasts and kissed her gently on the neck. She got scared and jumped, almost spilling the scrambled eggs from the bowl. During that jump, the towel with which her body was wrapped detached and fell to the floor. She was completely naked, and Mark hugged her leaning against her back. She turned her head to the left and gave him a passionate kiss. Their lips met and their tongues intertwined. She felt a growing erection pressing her ass. Mark rubbed his, now completely stiff, dick between her huge buttocks. His buttocks were big, his whole dick disappeared between them. Only the head appeared at the top when he pushed it upwards.

She felt Mark trying to place his dick on the entrance of her pussy. He was trying to give her a morning fuck. She moved her hips and pushed her hand between her legs to help him adjust. She finally aligned his head with the entrance to her pussy.

"Push slowly." she said. "Just go easy, I'm not wet enough yet."

He was obedient, her little boy. He pushed slowly, and the cock head entered her. She leaned her hands on the kitchen table, her ass pushed upwards to make it easier for him to penetrate her. He pushed slowly, a few inches and pulled out a little. With each push, he would conquer a few new inches of his mother's womb. After a dozen stabs, he reached the maximum penetration depths allowed by Marry's huge ass pressing against his stomach.

Steven liked to approach Marry from behind. And he loved watching her huge buttocks sway as he stabbed her. But this position did not allow such a deep penetration as some others positions, so it never stimulated Marry enough. She could never cum with Steven like this, but he fulfilled his needs because he would cum practically immediately.

It was different with Mark. His longer dick reached deeper, and his slender body allowed for a much better angle of thrust. She was filled with a wonderful feeling as Mark stabbed her from behind. He quickened his pace, her buttocks making waves with each push of his lower abdomen into them. The loud sound of skin-to-skin bangs spread through the kitchen - 'flap, flap, flap, flap ...'. Marry was already completely wet. Mark felt it and quickened his pace.

"Oh, Mom. Oh, oh, oh. How good is this. What are we doing, Mom? What are we doing?" Steven spoke in ecstasy.

"We're having sex, son! We're having sex while your mom prepares eggs for breakfast!" Marry said.

"Ah! Oh! Mom is mixing the eggs! And son is pounding mom!" he said.

All that fucking didn't last long. They soon came together again. Marry continued to prepare breakfast as her son's morning cum trickled down her right leg.

Breakfast was soon over. When they ate him hugged they went into the living room and started hugging and kissing.

They had sex almost all day. They changed poses in every way that came to their mind - missionary, doggy, she riding him, reverse cowboy. They did this in all the rooms in the apartment, including the balcony (which was very risky, since they could be seen from the street).

In the afternoon, Mark, hugging Marry, said "Have you ever had oral and anal sex with your dad?"

Marry shook her head.

"Dad never asked for oral sex, and I was never attracted to it, so I can say we never did it." Marry said. "We never even mentioned anal sex. I guess it's dirty so it never even occurred to us." she added.

Mark added: "I'd like to try oral and anal. Can we, Mom?"

Marry looked at him seriously.

"Anal sex is out of the question! I have hemorrhoids, my asshole would probably get inflamed. And to shove that huge stick of yours into such a small hole. No, that's out of the question!"

Mark obediently nodded "OK mom."

"And as for the oral," Marry added, "we could try that."

Having said that, she took his semi-hard dick in her hand and started kissing him from all sides. She paid the most attention to his growing cock head. She kissed it, and finally put half of the cock head in her mouth. She licked it with her tongue, and Mark was in ecstasy. Then she took the whole cock head in her mouth and started sucking it. She soon put half of her son's dick into her mouth. She wasn't particularly experienced, but Mark still enjoyed it immensely.

At one point she took Mark's dick out of her mouth and told him, "Please tell me when you are about to cum. I don't want cum in my mouth."

Mark nodded, and she continued to suck him. After about 15 minutes, Mark's orgasm approached.

"Now I'll do it, mom!!" he said in a spasm.

Marry took his dick out of her mouth and started jerking it off. Mark came like a volcano. Hot cum flew in all directions. Hot cum ended up on her tits, face, hair.

"Ugh, this was good!" Mark said.

After a Saturday-Sunday night filled with sex and kisses, Sunday morning finaly came. They woke up together and ended their love affair with slow, sensual missionary sex. They were tired after this adventure, but also happy and content. Mark was especially pleased. After sex, embraced, they began a conversation.

"Baby, our adventure is coming to an end." said Marry. "I hope you're happy."

"Happy?! This has been the best day and a half in my life! Most definitely! You're a wonderful mom. I love you, more than anything in the whole world. What mother would do this for her child." he said.

"I would do anything to make you happy. But you have to understand that we had an agreement. We all have to stick to that agreement. Do you understand?" she asked.

"Yes Mom, I understand. From now on there is no more sex, nor my attempts to peek and spy on you. Such was the deal, and I will stick to it. It will be difficult at first, but it will be fine. I will keep our time together forever in my heart and memory. Mom, you were not wrong to share this special time with me. I really have no desire to peek under your skirt anymore. Now I know exactly what is under that skirt," he said with a smile, "and how deep it is." he laughed out loud.

"Ha, ha really funny!" she said with false anger, "You came out of that depth, then you came back to it."

They laughed sweetly, hugged and kissed.

They got up and took a shower together. Then Marry changed the bedding, and inspected all the rooms in detail to remove traces of sex before Steven returned. In several places she found traces of crusted sperm which she had removed.

Around noon, Steven came with his friends. Marry and Mark greeted him with a smile on their lips. He looked at them questioningly, he could hardly wait to be alone with Marry.

"How did it go?" he asked impatiently "Did this 'therapy' of ours work? From your and Mark's look, I would say it did. Talk woman!" he continued in one breath.

"It was good, I think we succeeded." she said with a smile.

"How was he, was he ruff on you?" he asked calmer.

"No, just the opposite. He was very gentle and nice." she said.

"I knew it." Steven said contentedly. "He's a great boy. I knew he would be gentle. How did you handle it? Was it hard or awkward for you?" he continued.

"It was 'hard'. I was dealing with an 18-year-old." she said with a laugh. "But it wasn't that awkward. It was nice, even." Marry didn't want to lie to her husband.

Steven looked her in the eyes and kissed her lips gently.

"I'm glad you had a good time. I love you both."

Mark kept to the agreement. He stopped stalking his mother. On several occasions, he tried to talk about that great day together, but Marry always avoided that theme. That was for the best, and Mark agreed with her.

As a result of their wonderful day, a custom remained between mother and son that continued for many years to come - every time he got up in the morning, the Mark would kiss his mother's lips. That kiss was not a kiss from mother and son. It was a kiss between two lovers who remember the wonderful moments together they once shared.

Marry and Steven never violated the agreement.

A couple of years later, a development took place that brought the mother and son into a new family love triangle. But that is a completely different story that may be told later.Two years have passed since that sensual weekend during which Mark and his beloved mother Marry made love.

Steven's and Marry's plan to overcome Mark's obsession with his mother's body by Marry having sexual intercourse with her son, worked great.

Mark stopped stalking Marry, stopped jerking off in her panties, and peeking through the locks while his bulky mother undressed. Marry's big butt, wide hips and thick legs stopped being regular guests in Mark's dreams. An erotic weekend full of sex and love with Marry helped Mark overcome the advanced case of the Oedipus complex Mark had for years.

Mark began to socialize more with young people in school, and he became especially interested in young girls his age.

Everything was good in the Stevens family. The relationship between Steven and Marry did not change, although Steven voluntarily allowed his wife to make love to their young son. He had thought about it several times in the last two years, imagining what he could have looked like that weekend in their home.

On several occasions, he asked Marry about the events that weekend, but Marry did not want to tell him the details. Steven understood that she must have been embarrassed to tell her husband about the details of having sex with another man. Especially since that man was their son.

Steven managed to get some information from Marry. She told him they weren't doing any weird things. That they did it mostly in the missionary position.

"Did he ask you for anything kinky?" Steven asked on a couple of occasions.

"No, he wanted it classically. To be on me. During the day we tried some other positions. But we spent most of the time missionary, or me being on top," Marry said quietly, "He wanted to try both anal and oral. I didn't want anal, it's dirty. And it would hurt me."

"And oral sex?" Steven asked.

Marry was embarrassed. "I did that ... " She didn't finish the sentence.

Steven looked at her, a little puzzled.

"I thought you didn't like the taste of cum." he said.

"And I don't like it," she replied. "I asked him to tell me before he came. He didn't cum in my mouth. I mean ... He came everywhere except in my mouth." she said, remembering the eruption of sperm from Mark's organ after she sucked him.

Steven laughed.

"Our son has juice in his balls, huh?" he said jokingly.

"Don't ask. Every time a river of sperm came out of him. I guess that's the way it is with men his age." she replied.

"Is he big?" he asked.

"Pretty much," she replied vaguely.

That was, more or less, all the information he managed to get from Marry.

Several times he tried to imagine what it looked like. He tried to imagine his wife lying on their double bed, legs spread wide. He tried to imagine their son between those legs, his ass rising and falling as he rammed his young hard cock into his mother's pussy.

He got an erection several times, imagining Marry and Mark. But those fantasies of his were short-lived. Steven was bothered by all this much less than he expected. He expected to be at least a little jealous, but that was not the case. He didn't find it wrong, although almost everyone else would characterize this act of incest between mother and son as extremely sick behavior.

Everything was mostly forgotten, and life went on.

Mark went to college and he did well. He met a lot of new people with similar interests as his. He also met a couple of beautiful girls whom he dated.

The Stevens became a normal family again, like everyone else in their neighborhood. Marry and Steven often hung out with colleagues from work. They enjoyed socializing with both older and younger married couples.

One of the younger married couples with whom they were in close contact was Mike and Laura. They were both younger than Steven and Marry - Mike was 30 years old, and Laura was 26. Mike worked with Steven in the same office. Steven liked him very much. They also started hanging out with their wives, so Mike and Laura were frequent guests in the Stevens flat.

At one point, they started talking about children. Mike and Laura have been married for 3 years, but they had no children. Laura had trouble getting pregnant, due to some disease she had during her childhood. They tried a couple of times with artificial insemination, but so far they had no luck.

Marry told them how her birth went - when she gave birth to Mark, she barely survived.

"I've read all the books that exist about pregnancy, Marry," Laura said, "The difficult birth you had is a very rare complication. You can't have another childbirth complication like that. I think your fear of second pregnancy was exaggerated."

This conversation intrigued Marry. She started reading about the pregnancy problems she had while carrying Mark.

The Internet was full of information, she discovered that the complications she experienced during childbirth were a rare consequence of the special circumstances under which her pregnancy took place. The more she read, the more she felt sorry for not having another child after all.

As time went on, the desire to have another child started to grow.

She was thinking about it. She was 45 years old and has long since passed the ideal years for giving birth. And Steven was 52 years old, quite old to be a father. Also, a child had to be brought to this insecure world. It goes much easier when the parents are young.

All the arguments were against having a new child, but that idea never came out of Marry's head. As time went on, the desire in her grew. At one point, reading about raising a small child and remembering Mark's growing up, Marry said to herself, 'No matter what, I want another child!'. She decided to talk to Steven about everything.

Steven welcomed her wish with a surprisingly high level of understanding. Marry thought that Steven would not even want to hear about the idea of expanding the family. She was surprised that he listened to her thoughts at all. When she explained the circumstances of her first pregnancy, and her desire to have another child, Steven gave his opinion.

"I've always wanted to have another child. Honestly, it was my biggest wish. But I didn't have the heart to talk about it with you after what happened the first time. I didn't dare to suggest something like that to you." he said honestly.

"To be honest, if you had suggested it earlier I certainly wouldn't have agreed. But as far as I could see, the chances of problems happening again are virtually non-existent. Only risks now are due to my age." said Marry. "What do you think of all this, Steven?"

Steven felt his wife change her mind. She wanted another child very much, but she was scared. He thought briefly, he wanted another child. Even now, after all these years. He felt that they were not too old to be parents again.

"Listen, if you want it, I support you. I would like another child too. Even now, at my age. If you want it, I suggest you see a gynecologist. Let's hear the doctor's opinion on this issue," he said.

Marry thought for a moment.

"You're right, a gynecologist examination is a good idea. I'll do it," she said.

After a few days, Marry scheduled an appointment with a gynecologist. The gynecologist was an old doctor who's been Mary's gynecologist for years.

When she told him of her intentions, he said, "Hmm. You're a little old to be a parent, Marry. But that doesn't have to be a problem. You're a healthy woman and there's no problem with having another child. We'll do some more tests and see."

That day, a gynecologist performed tests. The results were done the next day.

"Honestly, the condition is much better than I expected. You are a very healthy women, Marry. The risks for pregnancy are minimal. If you decide to do that, I think everything will go without complications." said the old doctor.

Marry was overjoyed and hurried home tell everything to Steven.

Steven was happy, but also a little taken by surprise. 'We'll make a baby!' he thought. 'Diapers and crying and everything.' he laughed to himself.

Marry stopped taking birth control pills the same day. After years on the pill, she could get pregnant again. The feeling was strange. 'I'm going to carry a baby in my belly again. We will create a new life.' She was overjoyed.

Steven and Marry started planning the conception.

They closely monitored Marry's ovulation periods and made sure they had sex during those periods. They chose the poses that allowed the highest probability of conception, and after Steven's sperm was in Marry's womb, she would put a pillow under her lower body to increase the chances of fertilizing her egg. The fact that they were trying to conceive a new life gave a new impetus to their sex life. At the time they made love they were both very horny, much more than usual.

Months passed and attempts lined up. After 6 months of trying, Marry still failed to get pregnant. Considering that earlier examinations showed that Marry shouldn't have a problem getting pregnant, Steven decided to go for an examination.

In a conversation with the doctor, as the examination results were made, they've found out that conception could be problematic. The doctor told them that the number of sperm in Steven's has always been very small. That the first pregnancy was practically a miracle, and that the possibility of his sperm fertilizing Marry's egg at this age was non-existent.

Marry's world collapsed that day. In recent months, her desire for another child had become so great that she could no longer get it out of her head. Marry fell into depression, and Steven felt very bad. He desperately wanted to have another child, and he wanted, even more, to make his beloved wife happy. However, that was now impossible.

Lying in bed that evening, Marry stared at the ceiling.

"I'm sorry, Marry," Steven told her sadly, hugging her. "I'm sorry. You know I would do anything to make you happy."

"It's not your fault, Steven," she said.

"You think we should try artificial insemination?" he asked.

"No, Steven. I want the child to be ours. To both give part of ourselves into that child. To be made up of our genes." Marry answered quietly.

"Unfortunately, my genes can no longer be part of a baby," Steven said with a lot of sadness.

Marry was even sadder. Her husband's grief added to her own. Thinking about Steven's last sentence, she recalled the problems with Mark's Oedipus complex. And then it occurred to her: 'Steven's genes can still make a child! Steven's genes are in Mark!'

Steven saw a change on Marry's face.

"What's the matter? What came to your mind?" he asked.

"I think your genes can be part of a baby after all," she said softly.

"What do you mean?" Steven was confused.

"Your genes are in Mark," she said softly.

Steven thought, 'Well yes! She is right.'.

"What's your idea?" he asked.

"We could take Mark's sperm for artificial insemination. I believe Mark will agree to give us sperm. I'm just worried if they'll ask questions at the hospital, given that they know the status of your samples." said Marry with new hope.

"I like the idea." said Steven "But there could be a problem in the hospital." He thought for a few moments. "Do you think we should try by classical methods?" he asked.

"What do you mean?" she asked.

"Well, I thought ... maybe we could arrange for the two of you again ..." Steven couldn't finish the sentence.

"Steven! To sleep with Mark again?! And to try to get pregnant with him!? How could something like that get into your head?! And wouldn't something like that bother you?" she asked in surprise.

She did not expect such an idea from Steven, although he was a man of open views. This was a little too much though.

"Look at it this way: you've already had sex, so there aren't any mysteries there. I don't think it will be a problem convincing Mark to help us, I'm sure he'll agree. And as far as I'm concerned, we can do it this way. Of course, the decision is yours to make. What do you think?" he asked calmly.

Marry thought for a moment, "Well, maybe that will work. Will you talk to him?"

"I will. He will agree, I'm sure," said Steven.

That night Marry rolled over in bed thinking about everything. She will sleep with Mark again! Not only sleeping together but making a baby together! She recalled their weekend together two years ago. It felt really good, so she didn't worry about the sexual act itself. She moralized about the correctness of such away and soon fell asleep.

The next day, Steven went to his son for a talk. The conversation began with classic questions: 'How is college? Do you have friends? How was with the girls? ' After they had done that formal part of the conversation, Steven got to the point.

"Son, I have something to ask you. Mom and I need your help," he said seriously.

"Everything for your mom and dad!" replied Mark cheerfully, "Just tell me how I can help you."

He was glad there was something he could do for his parents, after years of them looking after him.

"It's a little awkward ..." Steven said. Mark looked at him seriously. "Your mom and I decided we had another child."

Mark looked at him, feeling a little awkward.

"But we have a problem. I'm too old, so we have a problem conceiving a child," said Steven.

Mark stared wordlessly at his father. 'Why is he telling all this to me?' he wondered.

"Do you remember your obsession with your mom two years ago?" Steven asked.

"Of course I remember," Mark replied.

"Then we helped you get through that crisis. Now we need your help," said Steven.

"What should I do?" Mark asked.

"Well, practically the same thing you did two years ago. But to make your Mom pregnant," said Steven surprisingly calmly.

Mark paused for a few seconds, it took him a while to process the information received. 'He ... He wants me to sleep with my mom again?!'.

"You mean, I should sleep with mom again?" said Mark, confused.

"Yes," Steven replied.

"And ... And ... Make a baby with her?" Mark asked.

"Yes," Steven answer calmly. "We can similarly organize everything like last time. I would be out of the flat while you do it."

Mark paused. Of course, he could not refuse his parents' request. But all this was very strange. And again, it was very strange two years ago.

"OK, Dad. I'll do what you ask," said Mark calmly. "I suppose Mom agrees?"

"Of course," replied Steven. "I'll let you know the days when it should be done. You make sure you are available during that period."

"OK, Dad," said Mark and went to his room.

Mark couldn't believe what his father said. He will have sex with his mom again! After the last time, he no longer thought about her in the context of sexuality. But after the talk with his dad, he felt a huge erection in his pants. He will have sex with his mother again, and he will fertilize her! He will make a child in her! He will be a father and a brother at the same time!

He took his hard dick out of his pants and started jerking off. He didn't last long, soon his semen was scattered all over the room. He removed the traces of it with a wet handkerchief and began to imagine re-coupling with his mother. It wasn't long before the erection came back, harder than the last one.

"He agreed," said Steven. "Do you want us to set it up like last time? Me to be out of the flat while you do it?"

"Yes. I think that's OK." She replied.

"When is your ovulation?" he asked.

"It starts on Monday. And it lasts for about five days, until Friday. That's the best time." she said, still quiet.

"So, what do you think I go out every night from Monday to Friday. Let's say at 6 PM. To give you a few hours, maybe until 10 PM? I'd be back in the apartment at 10 PM. Is that okay, is 4 hours enough time?" he asked.

"Yes, I think that's enough," she replied.

"Okay, I'll arrange it with Mark," said Steven.

An arrangement between father and son was made, and soon Monday came. Steven returned from work, had lunch, and at 6 PM he left the apartment.

Mark and Marry were left alone. Like last time, Marry went to Mark's room.

She knocked and said from the door, "Come to the bedroom in 10 minutes."

After 10 minutes, the scene from two years ago was repeated. Mark entered the room in a white T-shirt and shorts. Marry was waiting for him in her nightgown.

Marry took off her nightgown first. This time there was nothing under it, just the naked body of a middle-aged woman. She hasn't changed much from last time. She lost a few pounds but was still fat - with wide hips, thick legs, and a huge butt. Her pussy was as hairy as last time. She lay down on the bed and covered herself with a sheet. She invited him to lie down next to her.

He quickly took off his T-shirt and shorts and his hard, swollen cock appeared in front of Marry.

He crawled under the sheet, to his mother's right. For a few seconds, they lay like that, facing each other, and looking at each other.

Mark was the first to speak, "Can I kiss you, mom?".

She smiled at him "Of course love. Come."

Mark approached her and they soon found themselves in a passionate embrace. Their lips were joined and their tongues intertwined.

After a few seconds of exchanging saliva, Marry broke the kiss.

"We don't have that much time. Your father will be back at 10. Since we've already done this, the old rules are still on. OK?" she asked.

"OK, Mom. How do you want us to do it?" he said softly.

"Come on me." she turned so that she was now lying on her back. She spread her thick legs and bent her knees.

Mark wasted no time. In a moment, he found himself between his mother's legs. His swollen cock was aimed at her pussy. He stroked the entrance to the pussy with the head of his cock, to further lubricate the head before penetrating her pussy. She was already wet, so it wasn't long before she was ready to take him in.

Mark slowly pushed his dick into his mother. It was wet, so there was little resistance. He pushed half of the swollen organ into her pussy and stopped.

"Are you OK?" he asked.

"Yes. You can continue pushing. Just take it easy." she replied.

He was soon in Marry all the way. When their stomachs joined, Mark paused. Marry let out a long sigh, "Aaaahhhhh!"

He pulled his dick out halfway, then rammed it into her again, this time a little harder.

"Ahh! Ahh!" moaned Marry.

After a couple of pushes, he gained his rhythm, pulling his dick almost to the end and driving it into his mother.

"Ahh! Ahh! Ahh! Oh, God! Ahh! Ahh!" the room resounded with Marry's rhythmic sighs.

Mark slowly increased the rhythm, to which Marry responded with louder and more frequent sighs. They made love with a clear goal - to create a new life in Marry's belly.

Knowing that the goal of merging with his mother was fertilization, Mark plunged his hard organ vigorously into Marry. Mark fucked his mother. He fucked her. He tried to fertilize her with his sperm.

After 15 minutes of hard thrusting into his mother, Mark felt an orgasm approaching. Marry was also close.

"Here I come, Mom! I'm going to cum now!" he shouted. "Here's my seed for you!"

"Give it to me, love! Fill me up! Give me a baby! Make me pregnant!" dirty speech brought her to the brink of orgasm.

Mark pushed his dick into Marry all the way and started twitching. He came filling Marry's pussy with his hot semen. Young Mark's potent sperm filled his mother's womb, trying to reach her egg and start a new life. Marry reached her climax at the same time.

After half a minute their orgasms calmed down and they both relaxed and clung to each other. Mark was still between Marry's legs. His dick was driven into her vagina. His semen leaked from her cunt and dripped onto the sheets of the bed. They were trying to catch their breath.

"Uff...It was good!" said Mark.

Marry didn't say anything, she was probably uncomfortable, even though she had a very intense orgasm.

Mark's dick gradually shrank and fell out of Marry's pussy. Mark got off Marry and lay beside her on his side. Marry lay on her back, lifted her bulky ass off the bed, and placed a pillow under it. She wanted as much of Mark's semen as possible to reach the depths of her pussy, thus increasing the chance of conception. They were silent for a few moments, then Marry spoke.

"I have to stay like this for a few minutes. To get as much of your sperm as possible into the depths of the vagina," she said.

Mark hugged her and stroked her left breast lightly with his right hand. She said nothing, just put her left palm on his arm.

"Shall we do it again?" Mark asked. "Should we do it multiple times?"

"Yes. Just wait a few minutes," she replied.

After about 10 minutes, she called him between her legs again.

He fucked her at a slow pace, his arms resting on the bed next to her shoulders. Marry crossed her lower legs behind his back and occasionally put pressure on his ass to get as deep as possible into her. She was constantly letting out short sighs 'Ah! Ah! Ah! ... 'in the rhythm of his fucking.

This time it took about 20 minutes. He came into her like last time, pushing all the way in and emptying his balls into the depths of her pussy.

Marry spent the next half hour with a pillow under her ass, and Mark caressed her and kissed her breasts.

After half an hour, Marry pulled out her pillow and turned to Mark.

"Honey, that's enough for today. Let's take a shower and make the beds. Your dad's coming home soon." she said, stroking his head.

After the shower, Marry made the beds, and Mark went to his room. Soon Steven came too.

"How did it go?" he asked his wife.

"Okay, all according to plan. He filled me up twice. I think I should get pregnant by Friday." she replied.

"Good," said Steven.

The next 4 days passed according to a regular, almost monotonous schedule. Steven would leave the apartment at 6 pm, giving his wife and son 4 hours to mate.

After Steven's departure, Mark would come to the bedroom where his mother was waiting for him. She would always undress in front of him and invite him to bed. Mating always started with missionary sex - Mark would climb between his mother's legs and start pumping his swollen cock into her pussy. After filling her with semen, Marry remained on her back with a pillow under her ass for about half an hour. After that, the second round of mating would begin.

On several occasions, Mark fucked Marry from behind, in a doggy position that is also known to be good for insemination.

Friday finally came and went, ending the mating time between son and mother. Now they all have to wait to see will Mary get pregnant.

Marry bought pregnancy tests and she took the test. The tests soon showed good news - Marry was pregnant! Their plan to use their son for breeding has succeeded! She was pregnant again, she was carrying the fruit that came from her egg and the sperm of her Mark. The sperm that carried Steven's and her genes.

When Mark was told the good news, he was overjoyed. He will become a brother and a father at the same time!

After 9 months, Marry gave birth to a healthy baby girl named Martha. All the family members welcomed the baby and were happy in their apartment in the suburbs.
