After conquering three male protagonists, the substitute Shura field

The lines of his back were not as obvious as his abdomen, but his spine could be felt accurately and silently.

Shu Yan followed the bones all the way up, stroking the boy's bones bit by bit.

She completely ignored the boy's gradually increasing breathing.

"Sister, what are you doing?"

Kang Yu endured for a long time, but finally couldn't bear it anymore. He reached out and grabbed Shu Yan's hand that was causing trouble.

Shu Yan didn't feel guilty at all even though she was caught. After all, when she tried to stand up just now, the little fox pushed her back into his arms.

It's a matter of reciprocity. Since he hugged me, I should charge him some interest.

But she couldn't say it so bluntly. After thinking for a while, Shu Yan said, "I heard that students nowadays are under too much pressure from studying. Many of them have spinal problems and back pain. I'll feel your lumbar spine to see if there's any protrusion."

"Oh?" Kang Yu chuckled: "Did sister find out anything? Is there anything wrong with my waist?"

"The lumbar spine is straight, with no scoliosis or protrusion, and is still very healthy."

After a pause, Shu Yan added: "It seems that you have a hobby of exercising on weekdays."

After all, boys of this age are at the prime of their youth, but most of them are addicted to e-sports or the ocean of knowledge. Except for a few students who like sports or related majors, few have the habit of sticking to sports.

But Kang Yu is different.

After all, he was the one who had played exciting kissing games with Li Zhaoqing several times. Shu Yan could tell whether the muscles were developed through exercise just by touching them.

Kang Yu laughed dully: "It seems that Senior Sister does understand a little bit."

"I usually go running at night, and occasionally go hiking."

After he finished speaking, Shu Yan thought to herself, no wonder.

No wonder he has such thin muscles that are unique to teenagers.

It feels pretty good.

Kang Yu quickly let go of Shu Yan's hand. He was afraid that if he continued to hug her, he would lose control of himself.

After being freed, Shu Yan rested for a while, then dived into the water again. After swimming back and forth for several laps, she changed to a slow freestyle.

Swim for a while and play for a while.

The waves were rippling, and Shu Yan, wearing a dark green swimsuit, looked like a mermaid singing happily in the deep sea when she flipped in the water.

In a corner where Shu Yan couldn't see, Kang Yu took out his mobile phone and took a picture of her figure.

As soon as the photo was taken, the system reminded Shu Yan: [Host, Kang Yu secretly took a photo of you! ]

Shu Yan swung her two long, white legs in the water, and said lazily, "Just take pictures."

After saying this, he suddenly thought of something and his expression became serious: "Did he take a beautiful picture of me?"

The system carefully scanned Kang Yu's phone and answered Shu Yan honestly: [It's quite beautiful. The sunlight from the window shines in and shines on the host. The host looks like a mermaid! ]

Shu Yan really felt that the system had improved a lot recently. Hearing these compliments, it was hard to say without some level of expertise.

She was very pleased about this.

Of course, I am also very pleased with the beautiful photos taken by Kang Yu.

As long as no ugly photos were leaked, she would have no objection if Kang Yu took a full GB photo.

In the second half, Shu Yan rested for a while, but Kang Yu dived into the water and swam back and forth in the water for many circles as if he had endless energy.

Even the system was stunned: [What's going on? Is Kang Yu so energetic? ]

Shu Yan smiled as if she had understood everything. "Hey, he's young. Boys of 18 or 19 are full of energy. He hugged me for so long and even secretly took pictures of me from behind. You don't allow him to swim a few more laps?"

system:【……】

It doesn't want to be a system that will understand suddenly, but after being influenced by Shu Yan in recent times, it... is not clean anymore!

After swimming back and forth for more than ten times, the young and energetic Kang Yu finally returned to Shu Yan.

Shu Yan was sitting by the swimming pool with her calves immersed in the water. Kang Yu swam over and called her "Sister" first. After Shu Yan looked over, he grabbed Shu Yan's ankle and pulled her down. Shu Yan fell into the water defenselessly.

"ah!"

She screamed and grabbed nothing with her hands.

The next second, the whole person fell into a cool embrace.

Kang Yu held her in his arms.

He stood by the swimming pool. After Shu Yan was pulled into the water, he held her hips with one hand and supported her back with the other hand, and immediately pressed her against him.

Although Shu Yan was frightened, she was not injured.

At this moment, she was being hugged by Kang Yu, with her legs wrapped around his thin waist, her calves crossed behind the boy, and her hands subconsciously resting on his neck.

Coming back to her senses, Shu Yan's eyes were filled with anger. She raised her arm and slapped him hard on the shoulder twice: "You scared me to death!"

Kang Yu laughed softly: "Well, I was wrong, sister."

He said his apology but it didn't mean it at all.

Shu Yan was so angry that she slapped him twice, and only then did she feel relieved.

Kang Yu said nothing and let her hit him. After a moment, he saw Shu Yan's eyes reddened as she looked at her red palms.

Damn it, she hit him too hard and forgot that force is mutual. The harder she hit Kang Yu, the more pain she felt.

At this moment, the palm of her hand was red, and Shu Yan clenched her teeth and waited for the pain to pass.

Suddenly I hate this brat even more, what should I do?

Shu Yan lowered her head: "Kang Yu."

The boy looked at her: "Sister?"

Shu Yan smiled at him: "Hold on tight!"

Kang Yu subconsciously tightened the force holding her up, and then he saw Shu Yan lean over, open her mouth, and bite his shoulder.

"Um……"

Kang Yu groaned subconsciously, and Shu Yan loosened her grip a little, but still held on tightly.

After biting for about thirty seconds, Shu Yan finally loosened her teeth.

She raised an eyebrow at him: "Does it hurt?"

Kang Yu laughed: "Sister, I'm not a machine, of course I feel pain."

"It hurts!" Shu Yan smiled slightly: "Next time if you scare me like this, I will bite you on the other side too!"

Kang Yu immediately laughed twice, tilted his shoulder, and handed the intact side to Shu Yan's mouth: "Don't wait for next time, sister will bite it now!"

Shu Yan: “…”

You bastard! So you like S//M!

Shu Yan was speechless for a moment and could only stare at him.

Kang Yu then stopped laughing and stopped teasing her.

But the force holding her up still did not loosen.

Her skin is very white and smooth. Holding it in my arms, it feels like a piece of jade and feels great.

And it wasn’t heavy, so Kang Yu really didn’t want to let go.

Shu Yan, on the other hand, calmed down after she calmed down. She looked at the wound on Kang Yu's shoulder and gently touched it with her fingertips: "Does it hurt?"

She controlled her strength when she bit him just now and deliberately didn't bite him broken, otherwise her brother would have to get a tetanus shot.
