If they weren't going to go all the way... then at what step would they stop?
When did their yukatas come untied?
Why were the two of them doing this together?
What on earth happened while he was in the shower?
Is it really okay for this to be a reward?
The sudden flood of questions and confusion brought Chihaya Tetsuya's thoughts to a standstill, while the stimuli coming from all over his body made it impossible for his brain to focus on processing any of it.
With his vision blocked, his other senses were unconsciously amplified.
The sound of licking in his ears, the fragrance from their bodies, and the softness that was distinct enough to trace clear curves and shapes in his mind—it gave him the strange sensation of having his brain filled with a large amount of honey. Sweet, sticky, distracting thoughts made his consciousness slow and lax.
As their actions grew bolder, he once again realized just how many weak spots he had.
His ears, armpits, sides, the back of his knees, his groin—each spot was enough to drain the strength from his entire body, turning him into a toy for them to play with as they pleased...
Eh? Wait a minute... Why can they touch that place?! Where's my yukata? When did it come untied?!
"You two, wait a second!"
Finally, the overly dangerous sensation shocked Tetsuya's consciousness back to clarity. He hurriedly pulled his hands out from the softness on either side of him and hastily wrapped the yukata, which had come open at some point, back around himself.
"No matter how you look at it, this is going too far!"
"Hm? What are you talking about?"
Though her breathing was as ragged as if she had just finished strenuous exercise, Hoshino Ai still feigned ignorance.
"I haven't done anything special at all. What about you, Anon? Did you touch anything you weren't supposed to?"
"Me neither."
Chihaya Anon, also panting, denied it without batting an eye.
"I have no idea what Brother is talking about."
"You two... you're just shamelessly denying it now, aren't you?"
Tetsuya was completely dumbfounded by their refusal to confess.
"Not only did you secretly take off your own yukatas, you even untied my belt!"
"Hah, there you go again, talking about the yukatas."
Ai shook her head helplessly.
"If you really don't believe us, Tetsu, how about I turn on the lights right now to prove it?"
"I agree. Since Brother insists we did it, let's just turn on the lights and see."
Anon chimed in.
"How about it? Should we turn on the lights?"
"Of cour—No, wait!"
Just as Tetsuya was about to agree to turn on the lights to prove his point, he suddenly realized what would happen if he did.
Once the room was lit, their lies would be exposed, but he would also inevitably get a full view of their naked bodies. And if things developed to that point, he would have completely fallen into their trap...
"No, don't turn on the lights!"
Realizing this, Tetsuya quickly stopped Ai, who had already placed her hand on the switch.
"I get it, I won't doubt you two anymore! But no matter what, just let me re-tie my belt first."
"Hee hee~ That's better."
Seeing Tetsuya's reaction was exactly as she had predicted, Ai laughed triumphantly.
"Well then, Tetsu, you just need to keep sleeping."
(Are they really going to keep going...?)
Faced with their determination to deny everything to the end, Tetsuya, whose male physiological instincts had been fully awakened, had no idea how he was supposed to fall asleep now.
He knew very well that if he decisively surrendered or made a move on them at this point, they certainly wouldn't refuse him. But the consequences of doing so were far too severe. Not only would the relationship between the three of them be irreversibly changed, but sleeping with them was an absolute taboo that was unacceptable for him right now.
Although what they were doing was only "one final step" away from sex, he had to hold fast to this last bottom line!
(Just endure a little longer. This is just a reward for them... As long as I can make it through tonight, they won't have another chance to do this again!)
Tetsuya grit his teeth, repeating this over and over in his mind.
(So, I absolutely cannot lose to them!)
Just as Tetsuya was preparing to officially face this ordeal of unknown duration, only a few minutes later, he clearly felt Anon suddenly pull away from him—
...
(Ah, no... I miscalculated!)
Anon couldn't help but scream "trouble!" in her mind.
(At this rate, I might be the first one to break!)
Because when they were making the plan, they had only considered how to deal with Tetsuya, both she and Ai had subconsciously overlooked one fact.
While they were launching their assault on Tetsuya, they themselves had to endure the same level of stimulation.
The unprecedented intimacy, coupled with the sense of depravity from "bullying" her brother together with Ai, had made her body far more sensitive.
Just now, when Tetsuya's arm had inadvertently brushed past her chest, she had even flinched away subconsciously.
(This is bad. My willpower isn't as strong as my brother's...)
Anon couldn't help but swallow hard.
Needless to say, her breathing and heartbeat were already too fast. Her body had responded the moment it touched Tetsuya's, and if she wrapped her legs around him any tighter, he would probably realize her current state in an instant...
(Ugh, no, I can't rub against my brother, no matter what!)
Realizing she was almost at her limit, Anon had no choice but to retreat a little.
(How's Hoshino Ai doing?)
Anon lifted her head slightly to look toward Ai.
As expected, although she couldn't see clearly, the frequency of Ai's movements was also much slower than at the beginning.
That girl definitely didn't consider this either!
But it makes sense. For all her big talk, she's really just an armchair strategist who's still a virgin! Of course she'd overlook something like this!
Then, just as Anon was considering whether to signal that they should stop, Tetsuya, in an attempt to alleviate the stuffy heat of their skin pressed together, also shifted his body slightly as she pulled back.
And this movement, inevitably, caused him to rub against Ai, who was still clinging to him. The next second, when Tetsuya moved his leg, an extremely unnatural sensation, completely different from skin, scared him so much that he froze on the spot.
"—!"
Along with a suppressed whimper and a sudden, violent tremor coming from the other side of her brother's body, Anon instantly realized what had happened.
(Ah... He's done it now.)
Anon couldn't help but sigh inwardly.
(Hoshino Ai is so screwed now...)
Meanwhile, Tetsuya asked in a panic:
"Ai, y-you, what's wrong? Why are you shaking so much?"
"...It's nothing."
Hoshino Ai first answered with great difficulty, then slowly released her embrace.
But Chihaya Tetsuya was not reassured at all after hearing that and continued to press:
"Are you really okay? You were shaking super hard just now, even more than during the coldest winter back then! Are you not feeling well? Or is it some other problem?!"
"Mhm, I'm really fine..."
On the other side, even Hoshino Ai, who had always prided herself on having no shame, couldn't help but show an ineffable shyness at this moment.
The frustration of being the aggressor who ended up losing control first made it completely impossible for her to regain her usual confidence.
"Anyway... let's end today's reward here..."
"Mhm, let's end it here!"
Chihaya Anon also tactfully let go of her brother, while at the same time feeling a lingering fear in her heart. If her brother had rubbed against her just now, her reaction might have been even bigger than Hoshino Ai's.
Meanwhile, Chihaya Tetsuya, having received repeated assurances, first breathed a sigh of relief. Then, his attention was immediately drawn to a strange sensation on his thigh.
(Huh? What's this feeling?)
The unnatural dampness on his leg made Chihaya Tetsuya show a somewhat confused expression.
(It wasn't there just a moment ago...)
Could it be that Ai didn't dry herself properly after her shower?
I don't get it. But in any case, the fact that they were willing to stop was an undeniable relief for Chihaya Tetsuya.
He finally had a chance to let his overheated body cool down a bit!
Just when Chihaya Tetsuya thought he had completely weathered the storm, a scent slightly different from shampoo and shower gel, along with the lingering warmth of the two, suddenly reached him—
(I can't calm down at all...)
Chihaya Tetsuya let out an anguished sigh in his heart.
(Sigh, just how much longer do I have to endure this?)
And so, amidst Chihaya Tetsuya's cluelessness, Hoshino Ai's defeat, and Chihaya Anon's relief, this night with no winners finally reached a truce.
