While Kaguya and Kaede were finalizing their plans, Rin Ito also sighed in relief in the restroom of the port school. Karen, Shion, Misaki, and Eri Sawamura were so thoroughly played with that they could only gasp for air. However, Rin Ito only truly had sex with Misaki, Karen, and Shion. Rin Ito did not take Eri Sawamura's virginity. Although he could have sex with the bewildered Eri Sawamura, it would be a waste. Rin Ito only thoroughly teased her.
After taking care of the four of them, it was already afternoon, but Rin Ito didn't untie them. Instead, he turned his attention to Marin, who had been left exposed for several hours. Marin, sitting on the toilet, was in a similar position to Eri Sawamura and the others. Her bound hands were forced up, and her M-spread-eagled legs couldn't close. Although the pose was the same, Marin was in a much better situation than them... Although she had many vibrating eggs placed on her body, Marin was at least wearing her full cosplay outfit.
The only difference was that her purple lace panties were completely soaked, and drool dripping from the corner of her mouth had also soaked her neckline. Rin Ito removed Marin's blindfold and gag. Her black eyes were filled with lost confusion. If this were a Hentai, she would definitely have hearts in her eyes.
"Hah... Hah...." Marin, who had been left for several hours, gasped for air after the stimulation stopped. It took a while for the light to return to her black eyes.
"How do you feel?"
Marin glanced at the exhausted Misaki behind Rin Ito and said with lingering fear. "It was... incredible. Completely different from doing it myself."
Marin was not a pure Ojou-sama like Kaguya. She had bought a few vibrating toys herself after seeing female protagonists in Hentai and Galgames being comfortably trained with various toys. However, they were just ordinary small items like vibrating eggs. But... it was different. Completely different from when she played at home. When Marin used them herself, she could stop if the stimulation was too much or if it hit a too-sensitive spot. But when tied up, the helplessness of not being able to control her own body, the inability to avoid the most sensitive spots being touched, and the conquered feeling of being mercilessly pushed to the peak... all of this was something she couldn't experience alone with toys.
The experience was similar when substituting a real person for toys. The feeling of being pushed to the peak against her will was completely different from the slow climb when pleasuring herself. This was the first time Marin had experienced such a feeling. This was the feeling of... being conditioned.
"Want to try the real thing?" Rin Ito gently teased her through the soaked lace panties. A sweet sound escaped Marin's throat the moment he touched her.
"Ah?~ Wait... my body is still very sensi... Gulp!!!!" Marin tensed up and climaxed again.
Sure enough... this feeling of being conditioned against my own will is amazing!
After catching her breath slightly, Marin continued. "For my first time... I want it to be like Shizuku."
"I remember Shizuku's first time was at school, right? The classrooms here seem a bit dirty."
Hearing their conversation, Karen, who was still tied to the urinal, offered to lend them the student council room when they returned. If Marin wanted something more stimulating, they could even go after the school year started.
But for now...
"So... are you saying anything is okay, except for the 'first time'?"
"Eh?" Marin was stunned. She looked at Misaki outside the stall, then nodded, answering in a whisper, "Except for the first time... anything is fine."
"I see..." Rin Ito gently squeezed her soaked panties. "You haven't had water in a long time on such a hot day, and you've lost so much fluid. Are you thirsty? Want some water?"
Since his System Daughter had exchanged a temporary training boost, he might as well use it.
"Mhm." Marin nodded gently. She was indeed thirsty, but Rin Ito didn't go get water. Instead, he walked up to her. Marin was stunned for a moment, then quickly realized what was happening. Although she had been blindfolded earlier, she could still hear the sounds outside. Misaki said it tasted like pure water, with no flavor? Although this way of rehydration put a lot of pressure on Marin, the thought of Shizuku also being conditioned this way in Sticky Girl made Marin instinctively swallow and open her mouth, trembling.
"Ugh... Gulp...." Sure enough, just as Misaki had said, if she hadn't seen it with her own eyes, Marin would have thought Rin Ito was feeding her purified water!
Marin didn't know how many times she was forcefully pushed to climax until nightfall when they finally stopped and returned to the island together.
After a short rest, the next day quickly arrived.
"Uncle, I'm going back now~~~"
"See you when we get back, Big Brother~"
The day after the restroom play, Misaki boarded a boat to leave. Megumi Jinno left with her. Although Misaki wanted to experience all sorts of plays from various Hentai, she had many friends at school, just like Megumi Jinno, and she had already made plans with them before Eri Sawamura invited her. Marin was also popular at school and had many friends, but she canceled all her plans after Eri Sawamura invited her to the island. Misaki clearly didn't have Marin's level of dedication, so after fulfilling one of her wishes, she rushed back.
In the afternoon, during the hottest time on the island.
They had finished the simple snorkeling lessons. Actually, based on tourist standards, only one hour of training was required to snorkel and view the underwater scenery, but Karen made them train for a few more days for safety. However, after a few days of looking at coral, they all decided that an air-conditioned room was the most comfortable place on a hot afternoon! After Utaha recovered from the blow of being called "Cannon Fodder," the midday King's Game also resumed.
Just as they were about to start drawing for the King, Marin raised her hand and suggested, "How about we try a different way to play today?"
A different way to play? Under the girls' puzzled gazes, Marin presented her suggestion.
"We still draw the King, but instead of a command, the King can add one item/toy to someone's body... Then how about we put on our regular clothes and go play on the main island or at the port?"
Marin's eyes glittered with excitement. In the restroom yesterday, Marin was only placed there. Although her heart was itching listening to Misaki's sounds, Rin Ito didn't have sex with her; he only played with her using toys. She also wanted to be like Shizuku! However, the unused campus was too dirty with dust everywhere, so Karen promised to lend her the student council room when they returned.
But before going back... she could try the content from the Embarrassing Café DLC in Sticky Girl! In this DLC, the female protagonist, Shizuku, becomes a maid at a maid café during summer vacation, but underneath her long maid skirt, she is wearing nothing and is filled with all sorts of toys! Taking customer orders and delivering coffee while being conditioned... But a game is just a game. Whether or not she gets discovered in the game is entirely up to the author, but that's not the case in reality. Marin wouldn't dare actually get a job at a coffee shop, put on various toys, and go to work. Furthermore, she needed Rin Ito's help to experience the feeling of being conditioned and conquered, which she couldn't control herself.
However, if they just put on various toys and went out together now... that was perfectly fine!
