Xi Ning suddenly stopped panicking. He was sure that Song Zhou would not do anything to him. He rubbed Song Zhou’s nose fearlessly. “Mark me if you can.”

The atmosphere solidified for a few seconds, the force on Xi Ning’s wrist tightened for an instant, and Xi Ning struggled slightly.

Song Zhou quickly let go again. He looked frustrated while lowering his head. His eyelashes trembled lightly, and he whispered, “I want to kiss you……..let me kiss you, okay?”

Xi Ning actually heard a hint of grievance in his tone and his heart melted. “Okay……umm!”

Before Xi Ning could finish his sentence, Song Zhou blocked his lips like someone who had been exposed to the sun in a hot desert for several days finally came across a sweet spring, almost losing his mind.

Xi Ning’s tongue was tingling, Song Zhou had already let go of his hand, and kissed him for a while. He then embraced Xi Ning’s waist and lifted him up to put Xi Ning on his lap to continue kissing.

The second time Song Zhou was much gentler. He was teasing Xi Ning’s tongue little by little while reaching to the position of the gland behind Xi Ning’s neck with his right hand and rubbing it gently.

Song Zhou’s pheromone seemed to be more aggressive than the last time Xi Ning came into contact with it. Xi Ning uncontrollably wanted to rely on it but he was also scared at the same time.

“I want to mark you,” Song Zhou said while pecking his lips. “I want to……mark you and make you completely mine.”

Xi Ning couldn’t help but keep trembling. Song Zhou coaxed softly, “Don’t be afraid, don’t be afraid…… I already asked Dr. Li, and he said that we can kiss.”

Song Zhou had already contacted Doctor Li without Xi Ning knowing, and his words implied that he would only kiss Xi Ning.

Hearing this, Xi Ning slowly relaxed. Song Zhou kissed his face. “Good boy.”

Both of them sat quietly on the sofa for a while, Xi Ning calmly touched his lips and complained. “Are you a dog?”

He was bitten in his mouth. He didn’t feel anything just then, but now he felt a slight pain when he moved his mouth.

Song Zhou looked down, feeling a little distressed. “I’ll get you some ointment.”

Song Zhou got up and went to look for the ointment in the bedside table in the bedroom. As soon as he opened it, he saw the bottle of pheromone catalyst inside.

Last time when he took it back, he wanted to use it at first, but then he felt it was awkward to undergo gender differentiation through external forces, so he shelved it.

He stared at the pheromone catalyst for a while and then picked it up.

Song Zhou quickly came out of the room. He opened the ointment lid, dipped into it with his fingertips, and gently rubbed it on Xi Ning’s lips.

There was a faint chill sensation when the ointment was applied, Xi Ning pursed his lips and suddenly heard Song Zhou say, “Ning Ning, be with me.”

Xi Ning was stunned, not only because of the name that Song Zhou called him, and also when he raised his head to meet Song Zhou’s gaze, he saw complex emotions in his eyes.

Although Song Zhou didn’t say anything and didn’t show his feelings, he might still have a low self-esteem subconsciously. He always wanted to wait for himself to completely undergo gender differentiation before officially being with Xi Ning.

But he couldn’t wait anymore. Even though their relationship was unclear now, he couldn’t help but want to get closer to Xi Ning.

Because of his sudden sentence, Xi Ning’s blush that had faded away began to appear again and he said nervously, “Y-You why did……”

Shortly after that, Xi Ning felt that something was wrong. He suddenly smelled Song Zhou’s pheromone.

The scent was still the same as before, but the feeling was completely different. He could feel Song Zhou’s pheromone slowly pouring out from inside.

Song Zhou had completely differentiated.
