Special Occasion Rahul was only 21. He was the only child of wealthy modern couple at Calcutta. Anil chatarji, Rahul's father was a renowned businessman at Calcutta and very rich too. His wife Ruposhi was the headmistress of the biggest girls college at Calcutta. Ruposhi or Rupu was only 40 now. She was a modern up-to-date free lady, regularly went to clubs in rich areas of Calcutta and was a very active social worker. She even worked as a feminist. Rupu liked to dress very conservatively, never very revealing. Since she was the teacher of a girls' college, she liked to set exampled rather than preach it. But in her deep heart, she was not prudish. She understood the modern concept of sex and liked it better. Her husband Anil was busy most of the timed with his business, could not give much time to his wife. Rupu was not unhappy, but her sexual life was far from what she desires. As a conservative bengali mother of a grown up son, Rupu hardly let her sexual urge to surface. She maintains a regular happy mother, happy wife kind of air around her all the time. Only thing that kept Rupu from thoughting about her failed sex life was her only son Rahul. Rahul was a very good looking young boy and a great student. Both Rupu and Anil were very proud for their son. Rahul also plays cricket and was very athletic. When Rupu watch her son playing at the cricket field, ran like a bull and through the bowl in huge pace, Rupu could not hold back her tears from joy. She could not believe that this handsome boy once was her little son who suckled on her breast. Rupu loved Rahul more than anything in this world. It was Rahul's Birthday. As usual, his dad didn't care about it and went to a business trip. But the proud mother couldn't let the day went so easily. She decided to dress a little openly today. She wore a semi-tranparent chiffon sari. The sari was greenish, but more like raw Banana leaf color. The blouse was also made of the same see-trough materials. Finally a black bra made of fine silk with laced was underneath the blouse. When she finished having kajol on her big eyes, red moist lipstick on her full lips, a long pendant golden earrings which her mother gave her at her wedding, an intricate necklace of pure gold with expensive gems and a couple of dozens of glass bangled on both of her fair hands, she looked divinely beautiful. When she looked at the mirror how she looked, she realized that long forty years had done little damage to her stunning serene beauty. She could still pass as a young lady at her thirties. Rahul woke up from his sleep hearing his mom calling him from downstairs. He decided to freshen up quickly. When he got down to had his breakfast and saw his mom Rupu in her rather unusual look, he was very surprised. Rahul always knew that his mom was a very attractive lady and sometimed his friends gave hints to him that his mom was very sexy too. But Rahul never thought his mom as a sexy lady or a woman to desire. But seeing his mom this morning in such a nice sari and all these jewelry, Rahul for the first time felt something in him which was not exactly sonly love. It was a form of desire. Rupu bade him Happy Birthday warmly. He smiled. He somehow desired to hold his mom close and kiss her. He tried to drive away this thought from his mind and decide to eat his breakfast quietly. Rupu just watched her son eating. Oh god, she finally thought, "I love my son". Rahul was trying to concentrate at eating, but he could not avoid thoughting about how beautiful his mom was looking. When Rupu went to the kitchen to get the tea for him, he could not refrain his eyed devouring the wiggling motions of his mom's great big round ass. Rupu had a specially big ass. She got it from her mother. Although Rupu tried to exercise everyday, kept herself from being too fat, her ass would not shrink a shred of flesh. Finally she gave up. It was genetic. Besides, big assed were not that bad. Anyway, Rahul tired his best not to thought about his mom's great ass at least this morning, but it was no use. To make things worse, he developed a hard on. Then his mom returned with tea. Rahul was really worried if his mom took a notice of his hard on, then what will happen? How will he explain things? But when Rupu gave the cup of tea to his son, Rahul saw no unusual sings at her eyes. He was relieved. When Rupu was giving her the cup, her sari's pallu (or anchol) fell from her breast, revealing the big mounds of her pair of tits to her son. Rupu instantly gathered the sari to its right place, but the glimpse was enough for Rahul to guess how big his mom's tits really were. Even under the blouse and tight nylon bra, they were trying to come out of the confinement. Rahul's hard on just intensified at this. He could not thought anything now other than how sexy it would be to see those big tits of his mom. Rahul decided to finish his breakfast as fast as he could and go to the bathroom to pee. He knew there was no way for him than to masturbate now. But masturbating hardly helped him. The huge cock was as still as it was before. He had to fight hard to tuck it under his pants. When he got out of the bathroom, he found his mom sitting on the dinning table. He started to chat with her. They were talking about Rahul's childhood and how she raised him with so much love. Emotions were very strong inside her heart and tears began falling from her eyes. Rahul could not resist anymore. He went to his mom. Rupu got up, grabbed Rahul and began to hug her only son forcibly. Rahul was not ready for this. His mom's huge tits were pasted on his chest and his own bulging cock was touching mom's bare belly. But Rupu was unaware of all these. She kept on crying. Rupu's tits felt so good on his chest that Rahul decided to let this embrace go as long as mom wanted. His cock was trying to grow even bigger. Now Rupu could feel that his young son's bulging cock was poking her bare belly. But she couldn't thought anything about that. It was her own Son!!! But she liked the touch of the hard on. She was kind of surprised to find that she was getting excited imagining her own son's cock. She smiled to herself. She never realized before that she had such a horny desire. But Rupu did not try to resist the natural feelings. She let it come. Her emotions were gone now and she was now loving thoughting about his son's cock. She tired to guess how big it could be. She had never been fucked by any man other than her husband. Suddenly the phone rang. Finally the heavenly embrace broke. Both of them were angry. Rupu went to attend the phone and Rahul went to his room. After some time, he went to his mother's room and found his mom stooding before the window looking outside. Rahul decided to give mom a shock. So he tip-toed towards Rupu without making any noise. When He was only 3 ft away from Rupu's fair back and round ass, he took a good look at his mom's back. Rupu was wearing a very low necked blouse, exposing most of her back and shoulder. Her fair skin was smooth like butter. Rahul longed to lick his mom's bare shoulder and back. He could even make out the outline of her bra from her blouse. Rupu's back was so sexy that Rahul's hard on renewed with vigor. He could not thought straight. Somehow it seemed to him that this was a golden chance for him to show his love for Rupu. Mom was vulnerable and dad was not home. So Rahul grabbed Rupu from Behind saying, "Mommy". Rupu was stratled at this. She was a little shy since she was thoughting about the big cock of her son at that moment. Rahul was hugging Rupu very strongly, pressing his huge hard on onto mom's soft ass flesh. He even gave Rupu a wild kiss at her shoulder. Rupu turned around and hugged Rahul back, lovingly. She again felt her son's bulge at her belly. Then the mother and son went to the market to buy Rahul a birthday gift. Rahul got a nice wrist watch. He decided to give his mom something. He then took his mom to the Calcutta Sari Bazar and bought his mom two saris. They were very tranparent chiffon saries. He then bought Rupu matching blouses. One of the blouses was sleeveless. Rupu first opposed the idea of wearing sleeveless blouse at her age. But Rahul insisted saying that, "Mom, you will look very beautiful in them. Just wear them for my sake." Rupu could not say no. When they went the bra shop, the shopkepter asked for Rupu's size. Rupu blushed at this, her cheek became red in embarrassment. She only managed to say, "I am not sure. You have to measure." The shopkepter brought his tape and measured Rupu's breast size. Rahul was surprised to find that his mom's breast size was 40, even under her blouse and bra. They bought a nylon cupped bra. It was almost evening now. They decided to go home, dress themselves up for a party at a rich club that night which Rupu arranged for Rahul's Birthday. Rahul wore a silk kurta and Rupu wore the tranparent sari with almost tranparent blouse and the newly bought bra underneath. She made a big khopa with her long black hair, wore very deep pink lipstick and a high heel. Rupu looked so sexy in her see-through sari and heavy make-up and high heels that Rahul said, "Mommy, if you begin to look this beautiful from now on, you will have hard time finding a girl like you to marry me." Rupu blushed and said, "Okay, stop now. You look very handsome yourself too, son." At this point Rupu again noticed that Rahul's big bulge at the groin had not disappear. Rather it was more prominent now. She just smiled herself. She suddenly felt a wild sexual desire for her son's cock inside her right now right there. She decided to seduce her own son. Rupu asked Rahul, "Rahul, can I ask you something personal?" "Sure mom, you can ask me anything.", Rahul answered. "Now, it was very sensitive and a bit bad too. Thought first before answering.", Rupu looked very serious. "Okay mom, what is it?", Rahul didn't care to thought twice. "Son, why do you like to marry a girl like me?", was Ruposhi's question. "Mom, that's easy. You are very beautiful and pretty.", was Rahul's simple answer. "Am I only pretty? Not a little bit sexy so that you want your wife to be sexy like me?", Rahul never imagined his mom will bring this on. He somehow restrained himself and said, "Mom, look. Since you and I have been so free and frank today. I will not lie to you. Mom, you were very very sexy. Beautiful and sexy. Perhaps too sexy for a mom", Rupu was relieved to hear this from Rahul. She smiled and said, "Thank you son. But I guess you were saying this thing only to make me happy. Because, if that was true how come your father never looks at me anymore?", tears again started to fall from Rupu's eyes. Rahul wiped the tears from Rupu's cheek and said, "Mom, I did not know about dad. But for me, you are damn sexy. Sexier than any Bollywood actress. Now look what effect you have on your son, in case you didn't notice." Rahul showed his big hard on by raising his kurta. Rupu was now crying with joy. It was the best feeling she had ever had. Rupu only managed to say, "Thank you son for being so honest with me." Rahul could not let this chance go by. So he said, "Mom, I know it is not possible, but if it were somehow possible to love you like you have never been loved before mom, I would surely oblige." Rupu understood what Rahul wanted. But she was doubtful, "But, son I am your mom. We are not meant to be lovers." "Why not mom. I love you more than anything in this world. If lovers can make love, why can't we?", Rahul was eager. At this point Rupu thought to come out of her inhibition and said, " Okay son, I shall let to love your mom as the best lovers do. No limitations, no bindings. We shall forget we are mother and son. We will be just lovers." Rupu finally stopped crying and extended her hand to her son and said, "Come baba, come to mama." Rahul just jumped to his mom's embrace and put his lips on his dear mom's. Rupu took her son's eager lips in more passion and they kissed like two hungry tigers. Rupu put one of her hands on Rahul's big cock over his pajama and started to run her fingers over his bulge. She took one of Rahul's hands and rested in on her tits. She said huskily, "Caress mommi's tits, son." Rahul was in heaven now. He grabbed his mom's tits vigorously and started to knead then hard. Rupu let go Rahul and said softly, "Now son that's not the way to touch mom's tits. Be gentle son. But first, let me undress myself so you can see what mommi has for you inside." Rupu asked Rahul to sit on the sofa while she was undressing. First she put off all her jewelry. Then she let her hair loose. Next, the removed her sari from her body slowly. Then came off the petticoat. After that, the blouse and lastly the bra. Rupu was completely naked before her son now except the high heel. Rahul was dumbfounded by this. He had never imagined his mommy to be so stunningly sexy. Her tits were far bigger than what he thought even after today's incident at the bra store. They were big like two round cocoanuts, a little sagged from age, but still very firm and round. Her nipples were big too, brown in color. Her cunt was shaved. But She had a thin line of hair at her armpit. It made her more sexy. Rupu now said, "Don't keep mommy waiting son. Bring out your cock for mom." Rahul just let the pajama fall on the floor and his huge cock was fully visible. It was standing like a pole with some moister at the head. Rupu had never imagined Rahul's cock to be so big and fat. She could not resist herself anymore. She just touched her son's huge dick with her soft fingers. Her bangles made rini-jhini sound with it. Rahul's cock seem to grow even bigger at Rupu's touch. Rupu said, "Rahul, my dear, do you want mom to kiss your cock for you?" "Mom, please, suck my cock.", Rupu smiled at Rahul's eagerness and brought her tongue to the red head of his cock. She first licked the head, then took only the head inside her mouth. The cock filled her mouth completely. Rupu now was sucking her son like she used to suck the candy stick in her high school days. She took more than half the cock inside her mouth and gave the best blowjob. Rahul simply could not say anything, but came with strong force in his mom's mouth. Rupu swallowed all the cum Rahul had to offer. Now, Rupu stood up and asked Rahul to treat her tits like they deserve. Rahul first touched mom's tits with her hands. Then he started to press them slowly. Rupu liked her son's hand over her tits. She asked Rahul to lick the nipples. He started to lick Rupu's erect nipples. He now was licking all over mommi's tits and pressing them at the same time. Rupu was very wet in her cunt. She made Rahul sit on the sofa with his cock erect like a spear. She just pierced her cunt with the cock of her loving son. The whole thing got inside her wet cunt in a flush. Rupu gave her tits to Rahul's eager tongue again and started to fuck her son by riding him like a horse herself. Within minutes Rupu started coming. She came more than thrice before Rahul said that he was coming. Right at the last moment, Rupu took out her cunt from Rahul's cock and put the cock in her mouth again. Rahul came with more cum than before on his mom's mouth. Rupu ate all the cum. That was just the beginning. That night sexy mother and son fucked at least five times before they fell asleep in sheer tiredness. When Rahul got up next morning, it was about noon and Rupu was not with him. He went downstairs to look for his sexy mom and found that Rupu was cooking food for lunch wearing only that transparent sari, nothing else. Her fair and humongous ass was fully visible through the transparent sari. Rahul put off his pajama and brought out his erect cock. He then grabbed Rupu from behind and began to poke mommi's ass with his big pole. His hands were busy pressing his mom's big tits and his lips kissing Rupu's back. Rupu laughed at her son's wildness and said, "Son, you were horny for mommi again?" At this point, Rahul raised the Sari from Rupu's ass and asked Rupu to bend. Rupu bent on the kitchen counter, exposing her ample ass to her son's full view. Rahul first kissed the fair flesh all round the ass, then he put his tongue to the ass cheek. Rupu tired to restrain her son from it. But by this time Rahul was licking her hole so good that she gave up. Nobody had ever licked her asshole before. It felt so good. Rahul tired to insert his tongue as deep it went inside Rupu's ass and lick it. Rupu was now cummimg like a whore. Rahul then inserted his index finger in Rupu's virgin ass. It went pretty easily. He next put two of his fingers, then three, then four. Rupu liked Rahul's fingers in her ass so much that she asked Rahul to fuck her ass right now. Rahul set the head of the cock at the ass cheek and with a big stroke inserted the whole head in Rupu's asshole. The tight asshole gripped the cock head very strongly. Rahul could not move it any more. To Rupu, it felt like her asshole will burst. But Rahul started to stroke his cock slowly and gently. Rupu began to like it. After 5 minutes or so, Rupu's eager ass completely welcomed her son's cock inside. Rupu ask Rahul to increase his speed. Rahul obliges. Rupu liked every seconds of it. She screamed, "Rahul, my son. Insert the whole cock inside mommi's asshole." At this Rahul pushed his cock with such a force that the whole of it got inside Rupu's asshole. Rahul was mad with pleasure now. He fucked his mom like a lion fucks a lonely lioness. After 10 minutes of vigorous ass fucking, Rahul came in floods inside Rupu's ass. Rupu was completely exhausted by now. So was Rahul. The unsatisfied mother was now at the peak of pleasure and she was thinking about her bright future with her son's passionate love.
