Am I being simulated by their love affair.

Chapter 602 Pleasant Snorkeling and a Strange Menstrual Cycle

At seven o'clock the next morning, Tomatsu Yuka woke up to the faint sound of waves.

"Hmm..." She poked her head out of the covers and stared blankly at the ceiling for a while.

The air conditioning inside was just right, and it took the girl a few seconds to remember that she was on a school trip and that she was currently lying in a seaside hotel.

She lingered in bed a little longer before finally reaching for her phone with her hand under the covers.

The first thing I did, of course, was to send a message to Chun-kun: "Is Chun-kun awake yet?"

The boy replied quickly: "I'm already taking a walk on the shore, I'll be back at the hotel soon."

"So fast!"

The girl gasped softly, then realized that the others in the room were still asleep. She carefully looked up—the other two blankets beside her were still rising and falling quietly.

"Has Jun-kun had breakfast yet?"

"The hotel breakfast was pretty good, and I went for a walk after eating it."

"Then I'd better get up quickly too~"

Tomatsu Yuka immediately threw off the covers, quietly got up, washed up, changed her clothes, left the room, and slowly closed the door behind her.

She glanced at the time on her phone; it was not yet 7:30, and the corridor was quiet.

Everyone's probably still asleep... The girl walked towards the cafeteria on the first floor.

She needed to quickly finish breakfast and then go find Tsunkun—Mochizuki Haruka would definitely sleep in, and she wanted to seize every opportunity to be alone with her beloved.

Ten minutes later, Tomatsu Yuka walked out of the hotel. She blinked, and Tomiko Port, behind the swaying shadows of the trees, didn't seem as deserted as it had been yesterday; she could see quite a few people.

The girl walked towards the port at the bottom of the slope, and soon found her target on the shore.

Junichi Matsueda was squatting on the path on the embankment, showing the girl his profile in the sunlight. He held a piece of bread in his left hand and tossed it high into the air with his right. A flock of seagulls swept over his head, accurately catching the bread crumbs in mid-air.

"What a cool scene!" Tomatsu Tomoka said with a smile as she walked to his side. "It's a pity that Imokawa-san isn't here, otherwise she would definitely have taken a picture of this."

"Good morning." The boy turned around and held out the bread in his hand to her.

The girl imitated him, tearing off a few pieces and tossing them into the air, as seagulls circled overhead once more.

Tomatsu Yuka reached out and lifted the hem of her skirt, squatting down with the boy—she was wearing a plain white, cool sundress today, the same one she wore on Zushi Beach that day.

The girl looked towards the breakwater not far away. Kominato Shoko and the other teachers stood together, facing a group of young men and women in diving suits.

"Are those people chatting with Ms. Kominato the diving instructors?"

Jun Matsue nodded. "Snorkeling time is from 8:30 to 11:30. Kominato-sensei said there's no need to line up by class; it's first come, first served."

"I see..." Tomatsu Yuka covered her mouth and yawned softly. "That makes sense. Not everyone wants to try snorkeling anyway."

She looked at the crowd dispersing on the breakwater and asked, "In that case, could we be among the first batch of trainees?"

"should be."

Several speedboats started from the shore, leaving trails of white waves, and finally stopped in the nearshore waters outside the breakwater, forming a circle around the harbor—it seemed that was the activity area designated by the safety officer.

Kominato Shoko walked towards the boys and girls on the shore. "Are Matsueda and Yuuka planning to go snorkeling?"

"If you don't want to go into the water, you can take a bus to Izu Marine Park later."

Needless to say, Jun Matsueda nodded, and Tomoka Tomatsu also nodded, "Thank you, Kominato-sensei. I'd like to try snorkeling!"

"Great!" The female teacher clapped her hands. "Then don't just squat here, hurry up and find the instructor—you can start diving now."

“…Eh?” The girl’s eyes widened.

Kominato Shoko winked mischievously, "Anyway, there's no set order. If we start earlier, you guys can play a little longer, right?"

Twenty minutes later, as the students from the same class gradually emerged from the hotel, the two, now dressed in diving suits and wearing flippers, waded into the seawater, one step at a time, along the steps of the breakwater.

"Phew—" Tomatsu Yuka reached into the waist-deep water and splashed around. "It's still a bit chilly."

That's why we had you warm up before you went into the water.

The female instructor standing in front of her smiled; the young woman, who had been diving for many years, had somewhat rough skin.

"First, splash some water on yourself, squat down and move your hands and feet to get used to the water temperature."

As the woman spoke, she scooped up water and splashed it on the two of them. "You've got a great physique, young man. If you were a diving instructor, you'd be fully booked!"

Tomatsu Yuka smiled with her lips pursed. She stretched her limbs and walked in front of the boy, blocking the female coach's view.

"..." Matsueda Jun silently squatted down, letting his upper body soak in the seawater.

Before changing clothes and getting into the water, he originally wanted to choose the male instructor with the most muscular build. However, Tomatsu Yuka, who was standing next to him, quickly found a female instructor who looked friendly and reliable. He didn't know what the girl said, but the instructor pulled him over without saying a word.

"Alright!" The woman gently patted the water's surface. "Let's do a final check of our gear and get ready to snorkel!"

Jun Matsue stood up and looked at the girl's figure in front of him.

Tomatsu Yuka was wearing the uniform provided by the diving club. Her long hair was tied back in a ponytail, and the tight-fitting black wetsuit hugged her body from neck to toe, with only slender white stripes adorning her waist and forearms, highlighting the girl's graceful figure. In addition, her soft, full breasts, and the rounded curves of her hips and buttocks were clearly visible, captivating all who saw her.

"First, the face mirror!"

The boy picked up the swimming goggles hanging around his neck and pressed them tightly against his eyes. He watched as the girl in front of him lifted her high ponytail and pulled the straps of the goggles behind her head.

"Then comes the breathing tube!"

The two grabbed the curved tube fixed next to the mirror, opened their mouths and bit the front of the tube, completely covering it with their lips.

Tomatsu Yuka turned around, looked at the boy in front of her with his puffed-out lips, and couldn't help but laugh.

"Don't laugh when you get in the water! Cover your mouthpiece with your lips, or water will get in!"

The girl quickly nodded.

"Okay!" The coach walked up to the two of them. "Next, do a few more abdominal breaths, inhale the air into your stomach and exhale it out—abdominal breathing will be much easier underwater." The boy and girl fell silent, and the sound of breathing clearly came from their tightly clenched breathing tubes.

"Not enough! You need to breathe more forcefully while snorkeling!"

The woman took two steps forward, grabbed one of their hands, and placed them on each other's abdomens.

"Press close to the other person's stomach and really feel the sensation of abdominal breathing!"

"..." The two faced each other in silence for a moment. The coach released his hand, but they did not let go of each other's hands.

Jun Matsue lowered his head and looked at the girl's abdomen, which was covered by a wetsuit—the wet, close-fitting fabric looked black and shiny, and the flat and soft lines of her abdomen shimmered between his fingers.

The touch in his hand was warm and soft, and the girl's body rose and fell with her breath, her skin pressed into a few alluring indentations by his fingertips. At the same time, Tomatsu Yuka's five fingers were also pressed against the boy's body. Perhaps because her clothes were wet and slippery, the girl's small hands gently slid back and forth on his abdominal muscles.

"That's right~" The female coach nodded in satisfaction as she listened to the boy and girl's much heavier breathing.

"Remember not to breathe while underwater. Finally, turn around and check each other's wetsuits and fins!"

Tomatsu Yuka reluctantly lowered her hand, then slowly turned around, letting all her undulating curves flash before the boy's eyes.

"OK! We can officially begin snorkeling now!"

Leaving the underwater steps and heading deeper into the harbor, Jun Matsue held his breath and plunged into the sea. The cool seawater rushed past his ears, bringing a mesmerizing sound—like an open glass bottle sinking into the water. The clearly defined movements on the shore vanished in an instant, and the vague, ethereal sound of the flowing water echoed in all directions, enveloping the boy.

The underwater light shimmered with a faint greenish hue, and the seabed reefs came into clear view of Matsueda Jun. A group of tiny, bright blue fish swam back and forth along the reefs. As if sensing the approach of humans, the group of fish immediately scattered and hid in the crevices of the seabed.

With water rippling around him, Jun Matsue turned his head and saw Tomatsu Tomoka's face, which was wearing a mirror. The girl's long black hair, tied up, swayed in the water, and her eyes were filled with undisguised excitement.

The boy placed his hands on his face and pulled down the corners of his mouth. The girl, who was about to smile, paused for a moment, then nodded knowingly.

Being able to know when you want to laugh, that's what you call telepathy, right?
Tomatsu Yuka's smile widened as she swam with the boy toward the coach not far away, her long fins swaying in the water like a pair of perfectly matched mermaids.

An hour later, Tomatsu Yuka poked her head out of the water and, together with the boy next to her, clung to the lifebuoy that the coach had thrown from the speedboat.

Jun Matsueda lifted his goggles. "How are you feeling?"

"That's really interesting!" the girl laughed, her face flushed and wet.

"The corals are beautiful, and there are fish that look just like those in 'Finding Nemo' from elementary school—so colorful! I used to think all sea fish were ugly!"

"But Tsun-kun is so agile underwater, I can't keep up with him..."

The resentful look he received made Jun Matsue look away; he was a good swimmer and could easily shake off the girl.

The boy obviously didn't mean to do it, but Tomatsu Yuka kept swimming around and turning her body in front of him. Whenever this happened, the girl's movements would become extra energetic—twisting her waist, opening and closing her legs, jiggling her buttocks, which is not something to be appreciated while snorkeling.

As is well known, a low heart rate is required underwater, so Jun Matsueda kept his distance from Tomoka Tomatsu in order to prevent his heart from beating too fast.

The female instructor sitting on the speedboat waved her hand, "How about we finish after another hour of diving?"

"I'm fine." The boy nodded.

"I can rest for a little longer," Tomatsu Yuka said, as she propped herself up on the lifebuoy and turned to look at the embankment.

"..." There were many people around the breakwater, but she didn't see that familiar figure on either the water or the bank.

"Aren't you planning to go snorkeling, Mochizuki-san?" the girl asked instinctively.

That girl is so good at swimming in PE class, how could she not come to see Tsunku?

Jun Matsueda glanced at the shore. "She wasn't feeling well today and asked Kominato-sensei for leave."

Tomatsu Yuka breathed a sigh of relief. "So it was her period?"

"..." Of course, it wasn't because of his period, but the boy didn't intend to continue.

Last night, he and Mochizuki Haruka kept it brief, but the one-piece swimsuit was still torn to shreds—pieces of thin fabric hung on her fair, moist body, looking exceptionally alluring.

Although the exercise wasn't very intense, the girl definitely didn't sleep well, so it's normal for her to stay in the hotel to catch up on sleep during the day.

Thinking of the panting sounds that mingled with the moonlight and the sound of the tide outside the window last night, Jun Matsue felt his body, which was soaking in the water, seemed to get even warmer. He put his glasses back on and bit down on the breathing tube.

"I'm going back to diving now."

"Then I'm rested too!" Tomatsu Yuka also let go of her lifebuoy and followed the boy into the water.

At 10:40 a.m., Tomatsu Yuka put her sundress back on and walked out of the diving club's shower room. When the girl saw Matsueda Jun waiting for her at the door, Mochizuki Haruka finally appeared in front of her.

The eldest daughter of the Mochizuki family, dressed in a gothic-style lace little black dress, yawned impatiently.

"Waiting for you for a long time."

"...Girls always take a little longer to shower." Tomatsu Yuka flicked her slightly damp hair, sighing inwardly—her time with Tsunku was over again.

If it weren't for her limited physical strength, she would have loved to swim until the last few minutes before getting ashore with the boy.

Mochizuki Haruka completely ignored her words and turned to look at the boy on the other side, "Now can we eat?"

Jun Matsue nodded. "After lunch and a short rest, we'll take the bus to Kawana."

"You've used up so much energy snorkeling, you should eat a proper lunch, right?" Tomatsu Yuka walked up to him.

"I checked last night, there's a fried pork cutlet shop in town with pretty good reviews, it's less than a ten-minute walk from the dock, Jun-kun, would you like to try it?"

The boy took a sip of mineral water. "Fried pork cutlet rice bowl after exercise is the simplest happiness."

The smiling girl looked to the other side, "What do you think, Mochizuki-san?"

"Whatever you like." Mochizuki Haruka pouted and turned to walk out of the harbor.

To Tomatsu Tomoka's surprise, the journey was unexpectedly harmonious—she and Tsunku chatted about the tropical fish they had seen while snorkeling, while Mochizuki Haruka, who was walking ahead, didn't say a word, only occasionally glancing back at them.

Is this also because of her period...? The girl looked at the back of the figure in front of her, and the black lace dress swaying in the wind seemed to have temporarily lost all its aggressiveness.

"If she could stay like this forever, that would be nice," Tomatsu Yuka thought to herself.
