Ritam, 21 years, was taking his elder sister, Nimmi, 25 years, by train to their parental home from her husband's place for a domestic ritual. Nimmi was married a year back and stayed with her husband, Nirmal and his parents at a place that was about 700 kilometres from her paternal home. It was about twelve hours journey by train.
On the occasion of a religious ritual at her paternal house, Nirmal and his family members were invited by the in-laws to attend the function. Nimmi's mother-in-law was very considerate and suggested that Nimmi should go to her parental home a fortnight in advance to help her parents for preparation of the ritual while they would visit them a day or two ahead of the actual day of ritual.
So Ritam was given the duty to take his elder sister Nimmi from her husband's place to her parents' house. The train was at 9.52 PM and Nirmal dropped them at the railway station well ahead of time. They occupied the 1st class coup and as the train started they waved hands to Nirmal till he was visible on the platform. Within half an hour the TTE came to check their tickets and as he left, they locked the door of the coup and prepared to sleep. Dinner was completed at Nirmal's house before they had started for the railway station.
Nimmi took the lower berth on the right side while Ritam took the upper one on the left. The main lights were put off as they switched on the blue dim light of the coup. Both fell asleep within half an hour as the train started. At around midnight, Ritam felt the need to relieve his bladder and got down from his berth to go to the toilet. He did not put on the tube light as it was quite visible even in blue dim light and he also thought that bright light might disturb Nimmi's sleep. As he was getting down from the upper berth, his eyes fell on Nimmi who was sleeping in the lower berth opposite to his. Nimmi was fast asleep and her dress was disarranged in sleep. Even though it was an AC coup and they were using a sheet to cover themselves, Nimmi's cover had slided and slipped to the floor. Under the cover, Nimmi had perhaps removed her bra as it was kept beside her pillow and the wide neck of her salwar exposed her cleavage and her right boob was peeping out of her salwar. Ritam avoided looking at her further and went to the toilet. Her right hand was folded at the elbow and was under her between her head and the pillow and Ritam could see her clean shaved armpit.
While urinating, he recalled what he had seen minutes ago and the image of Nimmi's peeping flesh mound surfaced in his mind and immediately he could feel his manhood getting harder. He tried to keep the sight out of his mind and not to think of it again.
Ritam returned to the coup after urinating and knowing well that it was not right, he stood in the shadowy light of the coup looking at the armpit and the buxom boob of his elder sister that peeped out and tempted him. Under the dim light of the coup, Ritam stood watching Nimmi's exposed boob. It was his first experience to see a young woman's boobs from so near. He felt an urge to touch and caress the flesh mound but restricted his desire. For a moment, Ritam thought about putting the tubelight on to see the spectacle under broad light. But he decided otherwise because Nimmi might woke up if the light was too bright.
More Ritam looked at his elder sister's exposed boob and he was going crazy. He had never seen a young woman's boob so near after he grew up. In sleep Nimmi moved that further made the sheet covering her body to slide to the floor. He felt an intense urge to slowly remove the sheet further so that he can have a better view of both her boobs. But he was afraid should his touch awaken her.
At 25 years of age, Nimmi had buxom boobs and her snow white skin had a glowing smoothness. Ritam had heard his friends discreetly talk about the big melons of girls and women and he was then watching before his eyes the real melons heaving up and down as his sister breathed in sleep.
Ritam tried to guess the size of Nimmi's flesh mounds. Very carefully, he slided the sheet covering Nimmi. Now both the boobs were uncovered and one boob was protruding out of her loose neck salwar. Ritam decided to get on his berth above from where he could easily take the forbidden pleasure of looking at his sister's exposed flesh mound.
Once on the upper berth, Ritam watched and fantasized about touching, fondling and sucking those melons. The tip of his manhood got wet by the precum. He couldn't sleep; the image haunted him. Without being aware, his hand went inside his pants caressing his member that was bursting in excitement.
Ritam was so engrossed in his fantasy and masturbating himself that he didn't notice when Nimmi woke up and was watching him. He came back to his senses when Nimmi called him roughly. Ritam was startled at her voice. His hand was inside his pant and his eyes were fixed on Nimmi's partially exposed boob.
"Shame on you," Nimmi said angrily, "That you're a pervert and watching your own sis like the street guys. I never expected such nasty behaviour from you."
Ritam realised that it was disastrous to have been caught in this act by his elder sister. He jumped to damage control exercise by begging repeated forgiveness and requesting Nimmi not to tell anyone about it.
Nimmi adjusted her dress, covering herself properly. She felt so humiliated that she took her mobile handset and decided to call her husband. Ritam jumped down from his berth to prevent her from calling anyone and promised he won't repeat such behaviour. Suddenly, Nimmi looked mischievously at her brother and said, "I'm calling your Jiju (brother-in-law). Don't worry, I won't tell him anything about you. Just don't make noise and pretend to be asleep."
Ritam was not fully assured but he had no choice. So he sat beside Nimmi on the edge of the lower berth and thought, if necessary, he would snatch the handset from Nimmi's hand to prevent complaining about his behaviour. Nimmi called her husband and as he responded to the call, she put on the microphone so that Ritam could listen their conversation.
"Were you asleep? Did I disturb you?" asked Nimmi.
"Not at all," replied Nirmal from the other end, "Haven't you slept till now? It's almost midnight!"
"I was waiting for Ritam to sleep," falsely said Nimmi, "So that I can talk naughty with you."
Ritam's eyes widened as he heard Nimmi telling lie to her husband about Ritam being asleep. Perhaps Nirmal was not assured and he repeated the question, "Are you sure that he is asleep?"
Nimmi lied again, "I could hear hom snoring."
Ritam could not make out what Nimmi was upto, and he was still afraid of his action of watching his elder sister's boobs and jerking his tool. So he looked with awe at Nimmi. Nimmi simply gestured him to stay calm, pretend to be asleep and listen to the telephonic conversation. Ritam listened the conversation between Nimmi and her husband Nirmal, and the more he listened more awe gripped him, his eyes grew wider, his mouth opened and his tool was revolting inside his undergarment.
Nimmi was telling over phone, "I could not sleep without you caressing me. My body is burning to be one with you. My lips are looking for your lips. My nipples are waiting when will you suck them. My nether lips are missing the caress of your mouth and tongue. I am already wet to take your naughty younger John inside my hot hole. When we meet next, I will devour you like a hungry tigress. I will take you full in my mouth first and then between my legs."
Once she stopped, Nirmal replied, "Same here too, sweetheart. My member is longing for tender caress of your palms. It is erect and hard for the whole night. It's crazy to go deep inside your cave and release its load inside. My hands are missing your tender mounds, the damp smell between your thighs. You're my sexy doll. I am eagerly waiting to meet you at your place and I will make you scream in ecstasy."
Ritam could not believe what he heard. It was beyond his wildest imagination that a couple could talk so explicitly. For Ritam, the fact that his brother-in-law spoke so explicitly was not surprising as Nirmal was under the impression that Ritam was asleep. But he was surprised at the way his elder sister was speaking to her husband in front her younger brother was quite awkward and as if that was not enough, she had turned on the microphone to make her brother listen to the equally explicit response of her husband.
Ritam was hot at what he had seen but when he listened to their conversation, he grew red and started blushing. Secretly peeping at the nude beauty of his own sister was one thing, and listening to the hot and explicit conversation between his own sister and her husband was something quite obnoxious. It was as if he was watching the two making love in front of him. The telephonic conversation continued and it seemed that Nimmi was intentionally teasing Ritam for watching her naked boob. After about half an hour of conversation that mostly included the lustful desires of two partners, Nimmi concluded the call. She looked at Ritam. Ritam was still sitting with his glances on the floor. Nimmi broke the silence, "Hey, how was it, dear? Did you get horny listening to our conversation?"
Ritam didn't reply immediately. He coughed to clear his throat and then said, "I couldn't believe you two speaking this way in front of me."
"Don't confuse," Nimmi said, "I spoke in front of you. Your Jiju believed you to be asleep. He would kill me if he knows you were listening to our conversation."
"Why did you do this?" asked Ritam.
