Now Mio broke away from her trance, snapping back to reality in a mad dash to escape him as quickly as possible. She frantically yanked her body away, causing him to withdraw abruptly and his thick member to suddenly flop out of her tight anus.

She quickly leaped out of the bunk bed, tugging at her bright-colored pyjama shirt in an attempt to extend its length just a little bit further, covering more of her body. Shivering slightly despite the warmth of summer morning, she took a few steps back as if something were watching her from Haruto’s empty bed.

She didn't have much time to get situated or address Anon, as Yuki suddenly reappeared from the restroom.

Anon could see the amount of emotion that Mio was trying to process as Yuki initiated a conversation with her.

He was still coming down from the intensity of his climax and attempting to take in the escalating situation around him. Knowing that he couldn't draw any attention to himself, he forced himself to look away, hoping it would make him less conspicuous. However, that didn't stop his mind from racing with questions - what had just happened?

He could hear Mio responding to Yuki, her voice shaking but he could sense that she was trying hard to sound normal, like nothing had happened.

His gaze purposely averted from them, he could make out the floor of the train compartment, and noticed a wet spot below Mio. Beads of sweat ran down his face as he realised that it was his own cum dripping down from her ass, travelling slowly but surely as it made its way down her slender legs before hitting the ground. She had taken him deeply to places he hadn't known existed; and he had deposited a huge amount of cum inside of her ass over the two rounds they had engaged in.

He was worried that someone could come across the telltale evidence of his night with his lover on the floor, and just as he was contemplating this potential problem, Haruto unexpectedly entered the room. His face lit up with a loving smile when he saw his wife, and he quickly embraced her in a close hug and greeted her with a passionate kiss.

Anon could see Haruto’s arms tightly wrapped around Mio’s waist, pulling her closer to him as he kissed her. Mio seemed hesitant in responding, not really engaging in the kiss, but she was also making no effort to push him away either. She still seemed to be in a very overwhelmed and confused state.

Haruto didn’t seem to pay any attention to Mio’s condition and Anon could spot him how he went even further by gently squeezing and fondling Mio’s butt - the same one that just moments ago Anon had been inside of, pushing his own cum into.

Haruto released Mio's butt shortly after whispering something inaudible into her ear, turning away from her as if he had just shared a secret. Watching the two of them together like this made Anon's thoughts wander; he remembered how Mio had reacted and the words she had used when their bodies were intertwined, when he had accidentally penetrated her ass.

It was now evident to him that she had never allowed Haruto to fuck her ass before. And imagining Haruto trying to persuade and plead for Mio's permission aroused a strange sense of both guilt and extreme excitement in Anon.

Haruto and Yuki returned to their bunks and Mio excused herself, quickly heading to the restroom. Anon was relieved that no one seemed to have noticed anything of their intimate night's activities. He could still make out the big puddle of semen on the ground, an obvious trace left behind by Mio. He had to devise a plan for how he could conceal this evidence before anyone else noticed it.

After contemplating possible solutions, he decided that his best bet would be to hide it with the surrounding bags on the floor.

He hastily pulled his boxers up and got out of bed in a rush. His eyes fell upon the bags on the floor, but he acted as if he was merely looking for something amongst them to give him an excuse to move them around. Yuki didn't pay any real attention to Anon's movements, but Haruto had a mischievous grin on his face and teased Anon that it was good that he was still alive after all.

Anon had to be delicately cautious in order to get away with his actions. He took the bag next to the semen puddle, and slowly shifted it along over top of the mess until it completely concealed what was underneath. His plan worked like a charm; nothing seemed amiss and no one questioned any of his strange behaviour. He breathed an internal sigh of relief, feeling secure that he had gotten away with it.

After all the commotion Anon desperately desired a break. He carefully stepped outside their compartment into the hallway and eagerly opened the wide window to get some revitalizing air. His gaze was fixated on the beautiful landscape that had been lit up by the morning sun; trees, hills and winding rivers whizzing past as their train sped towards Bucharest. And as he watched, he couldn't help but feel a sense of admiration for his surroundings.

It was calm and peaceful yet mysterious, as if anything could happen at any moment. Even though he wasn't sure why exactly he had ended up on this little adventure with Mio, surely the rest of his journey was going to be full of more exciting surprises.

When Mio was coming back from the restroom, she looked more awake and refreshed. Anon had been watching her as she approached through the tight hallway. His eyes were glued to her, admiring her beauty even in an oversized t-shirt. Her perky chest was easily visible in the fabric of the top, her nipples poking subtly through the material. It was an alluring sight that he couldn't help but marvel at - a woman so stunningly gorgeous with only a simple piece of clothing on.

Mio was desperately avoiding eye contact with Anon, her cheeks turning a deep shade of red. She was eager to pass him and silently, not wanting to have an awkward conversation with him and facing the truth about their night together. However, Anon became more at ease and almost mischievous in his demeanor; he called out to Mio and greeted her in a loud voice.

He saw her jump a bit when he spoke, she had not anticipated that he would say anything and his mere presence was enough to make her uneasy.

Anon knew that confronting Mio directly may have been a bit harsh, but in his mind it was actually the best thing he could do for her. If they kept up appearances and acted normal around each other, then nobody would have any idea that the two of them were hiding something as monumental as there scandalous night together.

He also made no move to step out of her way or give her space, so they unavoidably brushed against each other as she snuck past him into the sleeping compartment. The contact sent a shiver through his body, as he was reminded of the night they had shared together.

Anon couldn't resist and he glanced over his shoulder to get one more look at Mio's backside. Her luscious, round bottom was barely concealed by her shirt, and its bubble shape was too much for him to bear. He'd never seen a sight like it before; the curves of her figure were truly something special.

It had been a while since Mio had disappeared into her bunk, and Anon was still standing at the window in the corridor, taking in the landscape and reflecting on last night. Haruto and Yuki had gotten up and started packing for their journey ahead. At some point, Haruto stepped out towards Anon to join him at the window. The two stood there for a moment in silence, marveling at the beauty of their surroundings.

A harmless conversation followed. Anon was savoring the moment; it was enjoyable to chat with the clueless husband, as images and recollections of his wife's butt and titts teased Anon’s mind. Nonetheless, Haruto also gave off a fun and good vibe; Anon thought fondly that if the circumstances had been different they could have been great friends too.

Yuki also joined them for a time, standing next to Anon and smiling at him. It was quite evident that she still held some interest in him, but with a lack of a common language between them it was hard to make any real headway. He wished he could have flirted with her.

Mio must have surely noticed the strange situation that was unfolding before her eyes. In the moment, she called Yuki over with a subtle wave of her hand, seeking help from her sister. It was clear that she wasn't comfortable with Anon getting too close to Yuki. Anon could understand her feelings and didn’t make any further attempts at Yuki,

Not long after their train pulled into the Bucharest main station, Anon watched as everyone packed up and prepared to disembark. He then noticed that Haruto had taken hold of the backpack he had been using to hide all of his mess. Anon couldn't help but chuckle at the sight; it seemed almost too perfect that Haruto had taken it without realising what substance was spread over and attached to it now.

When they stepped out of the train, it was time to say their goodbyes. Anon wasn't sure what was the proper way to do so, but Haruto moved forward and gathered him in a strong embrace. He then told Anon to stay in touch - perhaps they would be reunited again one day in Bucharest or any other place farther away. As a token of their newfound friendship he gave Anon his number on a folded piece of paper.

Yuki was initially smiling shyly at Anon, but in a moment that shyness had evaporated, replaced by a determined grin. She took a step forward and wrapped her arms around him, the hug more awkward than affectionate. Throughout it all, Anon remained focused on Mio; he could see the unmistakable nervousness in her eyes.

After Yuki released her embrace, she reverted to her typical timid stance and hesitant demeanor. She was taken aback by the sudden display of love she had shown for Anon, her cheeks blushing as a result of her boldness, almost as if it left her feeling embarrassed and exposed.

Anon was in a state of indecision; should he also go ahead and hug Mio? He thought about how it might come off as suspicious if she was the only one who did not participate in their goodbyes. After all, everybody else had already been wrapped up in an embrace.

Anon stepped closer and enveloped her in an uncomfortable embrace, saying goodbye with no response from Mio whose body remained rigid. He should have stopped there, but his impulses got the better of him as he closed the gap between their bodies more than what would be considered a normal friendly hug. He pressed her body into his and could feel her breasts pressing against his lower hest and it sent shivers through him; he wanted to reach out and grab Mio's bottom like Haruto had done before, but instead managed to pull away before it was too obvious of what he was attempting to do.

Then he picked up his bag, gave one last goodbye wave to the group and began walking away. After about 100 meters he glanced back, trying to locate them in the sea of people at the station. Eventually, his eyes fell upon the three figures walking towards the taxi stands. Haruto was again carrying most of their luggage while Yuki and Mio only had small trolleys and handbags.

Anon couldn't help but smile as he watched Mio take faltering steps, clearly struggling to manage the ache from the night before when he had stretched her ass to its limits.
