He was overly touchy with his mom and she could sense it past a certain point. He, who had a good toned body for a 21 y/o with 6’1″ and 70kg and messy hair those days. And she was 45 with plump lips, 38F cup, long thick hair tied in a pony tail and hair (going sideways from the front) and thicc hips to support her smart body. Glasses made her sexier.”How many times you are gonna hug me today?” She expressed her concern with a giggle.”I love you so much, mom, and it is Mother’s Day, so…” He hugged her one more time as his hands almost touched her hips.
She let out a bit of a laugh and went into the kitchen for cooking. A few mins later, he hugged her tightly from behind, she was taken back by a bit of surprise.. “Heyyy, what is it, hon?” He didn’t reply as his hard boner was slowly grinding into her ass and she could feel it. “Mom… I love you so much!”
“Yeah, you have told me that, like, ten times today. Are you okay, baby? Is something the matter?” She turned around, a bit worried, looking into his eyes red in lust.
“No, mom… I’m not okay… I want you…” His breath got faster…”Wh-what do you mean you want me? Are you sick or something?” She was now really worried trying to figure out the situation.
To her shock, in a jiffy he pulled her over and started kissing her lips sloppily and messily. For a first few seconds, she couldn’t fathom what’s happening but then she tried to push him off as their tongues rolled together while his mouth completely dominated hers. She punched him hard in the gut and he let her go. Their lips parted with a quick pop…
“WHAT THE FUCK WAS THAT?!” She was now shocked and angry at him…Tears slipped down his face, leaving her in further confusion. After all, she is a mother, she couldn’t see her son crying. She held his hands and looked up to him… “Are you going through a heartbreak? What is it? Tell me.”
“I see you as a woman, mom… I want to make love with you, I want to fuck your brains out, I want you to be my woman!” He uttered quickly in a single breath as her eyes widened in disbelief. Then disgust and anger gradually took over her entire body and her hand raised in the air to slap him but he grabbed her arm and obviously he could overpower her easily.
“You really doubt me, mom? Look below.” Both of them looked down to his big bulge over his boxers. “Why do I become like this everytime I see you? You think I’m bullshitting? I’m fucking attracted to you, mom, I have been attracted to you for years!” His other hand pulled down her top with bra, releasing her big tits out. “I’m warning you, gentlema–” She couldn’t complete her sentence as he started sucking off her nipples, her legs were gradually losing strength. He was sucking and eating out her tits like an animal as if to devour ’em. “So fucking tasty, mom…” He bit and licked her nipples as his other hand went down her panties to play with her clit and pussy that was gradually getting wet. She had started to enjoy this somewhat. He pulled her down and she was surprised to see his bull already out: big, thick, monster of a cock. “This is how much I love you, ma!” Before she could respond, he shoved his cock in her mouth and started throatfucking her deep down right from the start. She hadn’t tasted a cock since her husband passed away, almost as if something filled her in the moment but the fact that it was her son still gave her some reservations. He continued to fuck her throat like an onahole while her hands were now subconsciously playing with her kitty down there.
He pulled his cock out, she looked above, now pleasure and lust and love was in her eyes, she immediately got up and kissed his lips placing her arms around him. She had finally accepted him, her own son, as her man… Both of them undressed each other completely as their mouths playfully enjoyed the kiss while sharing saliva. They parted slowly, he looked into her eyes and he noticed her face was full of tears. “M-mom…?” She looked at him sadly, “But it’s wrong… We’ll never be accepted.” He held her hand and took her to the bedroom, they both stood in front of mirror and he held her from behind… “Look at our bodies closely, mom…” His arms tighten up around her body as his cock kept rubbing her slit from behind. “Reproduction is a phenomenon that comes naturally to even animals. What we are doing is socially and possibly lawfully wrong but biologically we are only adhering to the natural instinct we were born with. Sex is ultimate harmony between male and female irrespective of whoever they are to each other in an organized structure of society.”
“N-natural Instinct? Ultimate Harmony?” She was undergoing contradicting feelings. Then both of them heard that sound. Ovulation. “N-no way…” She unbelievably looked at her tummy and he plunged his big cock in her irresistible pussy. She let out a loud scream. He started thrusting wildly right then and there, “See, mom, you are ovulating, you want my fucking baby in your womb!” His hands constantly massaged her fine tits while fucking her from behind. “Y-you fucking beast, you are a fucking beast!” There was some annoyance and some pride in her words. She untied her pony and freed her hair out in open, he pulled a leg of hers up and started hitting her deep in her spots knocking up her womb.
“Y-you are right, this is only natural…” Both were going front and back, up and down on each other and their bodies were shaking in pleasure and he came in her cunt as she showered his cock with her love juices, she lost strength in her legs and they went down against the mirror looking into the mirror and seeing each other’s euphoric faces. They saw their true selves and the ultimate harmony between a male and female. And they celebrated their entire Mother’s Day in front of that mirror testing, trying and experiencing the natural instinct of love and lust.
