Leaving Rika in the living room to declare Aoi's sovereignty, in the restroom just a wall away, Aoi, as Ito's official girlfriend, placed the 'unconscious' Eri Ri on the toilet.
Golden eyebrows subtly twitched, Eri Ri quietly opened her azure eyes a crack, cautiously observing Aoi.
Aoi was seen pursing her lips, her expression a bit twisted.
"Uh, no need to pretend... I'm sorry."
"!!!!"
She... she was discovered!!!!
Seriously... even if she found out, wouldn't it be better to pretend not to? Saying it out loud just makes everyone awkward.
However, with Aoi having said that much, Eri Ri could only open her eyes and face the awkwardness.
"I'm sorry, uh... the prank went a little too far." Aoi guiltily averted her gaze, not daring to make eye contact with Eri Ri, her ten toes curling tightly together from embarrassment.
As a girl, Aoi also knew how sensitive that delicate area was. Aoi had only intended to make her reach climax from spanking to speed things up a bit, but she hadn't expected Eri Ri's reaction to be so extreme after the sensitivity was swapped with her butt.
"It's... it's nothing." Eri Ri gave an awkward laugh, "Hmm... my butt... was too sensitive."
Eri Ri herself was also startled.
Since she could remember, her butt had never been spanked, not even by her parents. Eri Ri herself, when bored, would at most pat it a couple of times while showering.
That one slap from Ito just now... even now, recalling it, she felt a lingering fear.
The moment his palm landed, an extreme pleasure she had never experienced before swept through her brain. It was no longer just the level of a female protagonist in a hentai book being spanked to climax.
Eri Ri felt as if even her soul and personality were about to leak out!
"I... I didn't even know my body was so..."
Eri Ri instinctively wanted to say 'promiscuous', but as soon as she thought of that word being used to describe herself, Eri Ri couldn't open her mouth... Although her sexual preferences were much more intense than those of typical boys, her body was still pure!!!!
Heaven knows why this happened!
The more Eri Ri said this, the more guilty Aoi felt.
I'm sorry!!! I'm so sorry for making you feel that your body is promiscuous!!!
Unable to tell Eri Ri about the system, Aoi could only apologize to Eri Ri in her heart.
The two fell into an awkward silence for a moment. The restroom door was not soundproof, so they could hear Rika's voice from outside, who was throwing a party on behalf of her sister.
Hearing the charming sounds that rarely came from Rika's mouth, Eri Ri's heart itched... If she were to use the manga terminology Eri Ri was familiar with, Aoi was a somewhat clumsy, energetic girl who often made blunders, and Rika was a dark-bellied kuudere character.
Eri Ri really wanted to see what kind of cute expression the dark-bellied kuudere Rika would show when she was partying.
"Do you want to go?"
"I don't want to, I don't want to, I don't want to..." Eri Ri quickly waved her hands. No matter how much she wanted to see, she couldn't say it in front of her girlfriend...
Wait!!!!
At this moment, Eri Ri finally reacted.
Ito was Aoi's boyfriend! Why was Aoi so calm about letting Ito party with them!? For a moment, Eri Ri didn't know how to phrase her words.
"They... you..."
"What does it matter?" Aoi said to Eri Ri, feigning magnanimity and confidence, "Anyway, in the end, he'll still love me the most!"
She couldn't possibly say she had a cuckolding fetish, could she?
Besides, she didn't have such a fetish! This was all the system's fault! How could she have such a fetish!?
"Ah, this..." Eri Ri's mouth twitched, and she hesitated to speak.
Good heavens, Eri Ri exclaimed, good heavens.
No wonder Nanami and Mashiro openly lived at Ito's house, and no wonder Sakuramiya Hinata publicly declared at the school gate that she was Ito's girlfriend.
Now everything made sense. It turned out that Aoi had always known and always allowed it.
"Moreover... if he has more experience, I'll also be more comfortable." Aoi continued to feign indifference, staring at Eri Ri's butt. "Otherwise, he wouldn't have made you like this with one slap."
"Ugh!!!" Only then did Eri Ri notice that her sweatpants and underwear had been pulled down to her bent legs since earlier, and her messy, sticky 'garden' had been in Aoi's line of sight the whole time.
Eri Ri quickly covered herself with her hands.
"Although there's a dryer, they can be dried quickly after washing, but... if you still want to continue participating in the material-gathering party, it's better not to wear anything."
A hint of provocation entered Aoi's eyes and brows. She had known Eri Ri since high school, and she understood her tsundere personality perfectly.
Eri Ri gritted her silver teeth, putting on an extremely fierce expression.
Now Eri Ri understood. Today, she had come to catch herself in the act! And she had deliberately pulled off her sweatpants for him to spank her!
Hmph... Was she really that confident, not afraid of being taken by those girls in a day or two?
If that's the case... Hmph!
Eri Ri took a deep breath and met Aoi's gaze with the same intensity.
"Hmm, you have a point." Eri Ri took off her sweatpants and underwear and handed them to Aoi. "Since you just said it was your fault... then please wash and dry my sweatpants and underwear for me! I'll go to the material-gathering session first, and then go home after the pants are dry."
It wasn't that Eri Ri really wanted to cuckold Aoi; she and Ito had only met for the first time today, so love at first sight was out of the question.
She had just been targeted by her 'catching her in the act,' so if she didn't do something, wouldn't she have been spanked to climax and wet herself for nothing!?
Of course... she wasn't really going to do anything to Ito.
She was just going to 'retaliate' against Aoi a little.
Participating in the material-gathering party could both get revenge on Aoi and gather material for her manga. Two birds with one stone!
That's right! That's it!
Let Aoi, who deliberately scared her and made her wet herself and climax, wash her dirty pants herself now!
"..." Aoi's mouth twitched. She was going to the party, and she was in the bathroom washing her underwear, right!?
Before, Aoi had felt a bit sorry for Eri Ri, but if that's the case... Hmph hmph hmph.
One day, she'd stuff that sticky underwear into her mouth!
Besides the sensitivity exchange, the system also had many enhancements that could only be found in hentai books.
Eri Ri wiped her messy crotch with a tissue and then stood up, tightening the hem of her tracksuit.
Just like Mashiro occasionally wore Ito's shirt as pajamas or a dress because it was troublesome, Eri Ri's tracksuit, bought for comfort, was relatively loose.
Although the difference wasn't as great as Ito's shirt and Mashiro, it worked perfectly as a super short dress. As long as she didn't make any big movements, it shouldn't reveal anything.
After giving Aoi a provocative look, Eri Ri left the restroom. After tightening the hem of her tracksuit, Eri Ri walked towards the living room... What kind of expression would Rika make when she climaxed?
