The greatest difference between ABO humans and ordinary people, aside from their sex and pheromones, is above all the scent glands. The scent glands give birth to pheromones, and they also determine a person’s sex and the value of that person’s existence.

Alphas possess formidable physiques and pheromones, which is why they can mark Omegas or Betas. But for an Omega, there is another way to make an Alpha belong to her. Just as Liu Zhaoran had done moments ago: she bit through Song Nanyin’s scent gland opening and injected her own pheromones into it.

This act is called imprinting. It sounds rather romantic, like a ritual passed down from ancient times.

Song Nanyin would become more sensitive to her own pheromones, and would even be stirred by her own scent. Her desire and craving would grow intense, and she would only ever feel this way toward herself.

This sort of imprinting in fact mostly occurs between AO couples who have already established a relationship but lack a sense of security. Liu Zhaoran, however, did it simply because she wanted to, and so she did.

In this world, only the two of them were ABO humans. In a certain sense, they could only ever smell each other’s pheromones.

But Liu Zhaoran still wanted to see what Song Nanyin would look like after being imprinted by her.

“Team Leader Song, what’s wrong?” Liu Zhaoran asked, knowing full well, a hint of a smile in her eyes. Song Nanyin leaned in her arms, her breath scalding hot, even more seething than the hot spring pool.

“You bit me… but… why does it feel so good?”

Song Nanyin touched her neck and faintly felt the tooth marks at her nape. She thought Liu Zhaoran was strange, and herself even stranger.

By all rights, being bitten by the Black-Hearted Lotus should have hurt and made her angry. Yet not only did she feel no discomfort, the instant Liu Zhaoran’s teeth sank in, a tingling, delicious pleasure spread through her whole body.

It was like an electric current flowing along the nape Liu Zhaoran had gnawed, like a cup of water poured onto parched ground, absorbed in an instant without a drop left.

Song Nanyin didn’t understand why her body reacted this way. When Liu Zhaoran bit her just now, it felt as if something had entered her body.

“Maybe it’s because Team Leader Song likes being bitten by me too? It felt good, didn’t it?” Liu Zhaoran had absolute confidence in her pheromones. Their concentration was extremely high; a Class S Omega was not something you came across every day.

Here she couldn’t determine Song Nanyin’s pheromone rank, but judging by pheromone concentration alone, she perhaps barely reached Class B.

Liu Zhaoran didn’t mind. After all, Song Nanyin’s inexplicable differentiation into an Alpha was strange enough; having differentiated at such an age, it was understandable that her pheromones were scarce.

And precisely because of that, she was all the easier for her to bully.

“Can’t you think about something clean for once? We’re still in the hot spring pool. What if someone sees?”

Song Nanyin shifted backward, trying to escape Liu Zhaoran’s hold. The other woman seemed to read her intention, pressed herself close, raised a leg, and rubbed with her knee. Her little part was pressed against her belly and ground back and forth. Song Nanyin gasped softly and hugged Liu Zhaoran tighter.

“No one will see. We’re on the highest spot; nobody will notice. Besides, I’m not wearing a thing. Team Leader Song at least still has a swimsuit to cover herself, doesn’t she?”

“But… you… mm… ah…” Song Nanyin’s voice suddenly rose, as if she hadn’t expected Liu Zhaoran to press down hard all of a sudden.

Her little part was fragile even when erect, and with Liu Zhaoran pressing it with her knee, Song Nanyin couldn’t help but hurt.

Her legs went weak beyond measure. Whether it was from the hot spring soak or from Liu Zhaoran’s teasing, she couldn’t say. Perhaps both.

“Sorry, I hurt you. Let me rub it for you.” Liu Zhaoran’s voice suddenly dropped, hoarser than before, yet somehow gentle. The hand resting on her own shoulder slid into the water, stirring the ripples, and stroked that place through the swimsuit.

Song Nanyin couldn’t describe exactly what it felt like, but her nape burned hotter, and her body grew even warmer.

“Team Leader Song is so wet. Let me help you; that way, you can help me properly afterward.” Liu Zhaoran was shameless enough to describe making love as if it were neighbors helping each other out.

Song Nanyin indeed hadn’t taken off her swimsuit. Liu Zhaoran merely hooked the flimsy fabric aside from one side and, slipping through the gap that opened, slid inside.

Her fleshy lips were engorged with arousal, soft and plump to the touch. Squeezing them felt like gripping a sponge soaked through with water; the slightest squeeze would send a great deal of juice spilling out.

Liu Zhaoran didn’t squeeze. Instead, she reached straight into the depths of that sponge, entering the scalding, slick cavity walls. They had done this many times, yet it was still too tight to take two fingers from the start. Liu Zhaoran pushed both fingers in together and was clasped so tightly she couldn’t move.

“Why are you using two again? It’s too full. Take one out…”

Song Nanyin had no choice but to hold on to Liu Zhaoran, afraid that a single slip would send her toppling into the hot spring. She pounded Liu Zhaoran’s shoulder twice, annoyed that the woman was bullying her again for no reason.

“Can Team Leader Song bear it a little while? You look so beautiful right now. I can’t wait to use two fingers. Sorry.” Liu Zhaoran’s voice was hoarser than usual, and only then did Song Nanyin notice that her cheeks were even redder than her own.

Liu Zhaoran panted rapidly, and the body pressed against her own was burning hot.

“Hey, are… are you okay? Is it too hot?” Song Nanyin switched from clinging to Liu Zhaoran to cradling her in her arms. She kept feeling as if Liu Zhaoran now looked like the one who needed to be bullied more.

“I’m fine. I just… want it too. Team Leader Song will have to help me properly in a little while.” Liu Zhaoran curved her lips into a smile, and even her breath was scorching. She knew she was probably entering her heat cycle. Her heightened-sensitivity phase had already lasted several days, and with the imprinting of Song Nanyin just now, plus the Alpha’s pheromones she had inhaled, falling into heat was hardly surprising.

Liu Zhaoran was a calculating person, and she let calculation seep into every aspect of her life. She knew her heat cycle, and she exploited it at this very moment.

In the past, she would never sleep with any man or woman during her heat. But now, with Song Nanyin’s appearance, things seemed to have taken a turn.

She didn’t dislike Song Nanyin. On the contrary, she was rather fond of this foolish lion. A great body, a face that needed no further comment, and even the taste of her pheromones suited Liu Zhaoran’s fancy. A pheromone rank far below her own, along with her complete ignorance of ABO humans, were all favorable conditions for Liu Zhaoran to control her.

She could accompany her through her heat, because once an Alpha was affected by her pheromones and fell into heat, she could match an Omega’s stamina for as long as three full days. Moreover, Liu Zhaoran also needed Song Nanyin’s pheromones. It could be called killing two birds with one stone.

With this in mind, Liu Zhaoran held nothing back, letting her pheromones flow wantonly.

They had been confined for far too long. On ordinary days, even an inadvertent leak would go unsmelled by anyone, with no one to invade. Now they had a target, and like beasts starved for too long, they wrapped Song Nanyin in an invisible net of scent.

“Black-Hearted Lotus… you… mm…” Song Nanyin’s body went soft, and she barely managed to hold herself up against the edge of the pool. She felt that Liu Zhaoran didn’t seem to have any strength left either. If she herself fell, wouldn’t this woman collapse along with her?

But why did Liu Zhaoran’s scent keep getting stronger? It was as if the scent had a will of its own, wrapping around her and closing in on her. Her nape grew hotter and hotter, as though something hidden inside were ceaselessly butting against the skin, trying to get out.

Song Nanyin couldn’t describe the feeling. She simply felt that she, too, was about to give out…

“Does Team Leader Song like this?” Through the swimsuit, Liu Zhaoran gently stroked Song Nanyin’s chest. Perhaps for comfort while soaking, Song Nanyin had taken off her bra after entering the hot spring pool.

Right now, the swimsuit clung tightly to Song Nanyin’s perky fullness. Spurred on by desire, her nipples stood high, even pushing a not-small round bulge against the swimsuit.

Through that layer of obstruction, Liu Zhaoran rolled the nipples between her fingertips, pinching again and again. As if that weren’t enough, she would tug at the buds, drawing them outward.

By now, the cavity where her fingers lay had fully softened, filled with countless fluids, somewhat sticky. When the fingers stirred inside, one could even hear wet squelching sounds.

Liu Zhaoran sank deep, then drew back shallow. Her lips and tongue took the place of her left hand, suckling and nibbling at the nipple, while her left hand moved downward, the web of her hand grinding against the tip of her little part.

“Mm… Black-Hearted Lotus… ah… so… so good.” By now, Song Nanyin had learned to show a bit of honesty in bed; the most obvious sign was that she no longer yelled “slower” when what she meant was that it felt good. Of course, it was also because even if she yelled, Liu Zhaoran wouldn’t obediently listen.

The throbbing in her cavity was unmistakable, and the reaction of her little part was even clearer. The swimsuit was so close-fitting that every response was plainly visible on the fabric.

The tip ground by the web of Liu Zhaoran’s hand trembled, pulsing in her palm without cease. Her entrance contracted violently, spasming and clamping tight around the two fingers Liu Zhaoran was working in with effort.

Song Nanyin’s climax came fast, so fast that Liu Zhaoran hadn’t used any technique at all, and both places bloomed together in her hands.

Between her fingertips was the core’s fervent reward, trickling down her knuckles to the roots of her fingers, dripping into the hot spring with a patter.

Her palm also received a gift from the little part, scalding and viscous, seeping slightly through the swimsuit’s thin fabric. Pale white, rather noticeable against the black material. The inside of the swimsuit must certainly be a lewd mess.

“Team Leader Song has gotten her swimsuit dirty. You’ll have to wash it properly when we get back.” The culprit spoke with a smile, letting out words that made one want to hit her. Song Nanyin blinked, blinking away the tears that physical pleasure had brought to her eyes.

Even while still savoring the aftermath of her orgasm, she had to take a dig at this Black-Hearted Lotus.

“And whose fault is that? If it weren’t for you, how would I have gotten my swimsuit dirty? I told you we’d do it when we got back.”

Song Nanyin found the inside of her swimsuit sticky, and with the thought that it was all her own “fluids,” she felt completely done for.

“But I think Team Leader Song is more sensitive today than ever. You haven’t come this fast in a long time, which just goes to show how good it felt for you. Now that you’re satisfied, are you going to abandon me?”

Liu Zhaoran leaned in Song Nanyin’s arms, saying this between breathless gasps, and somehow she even looked a little fragile. Song Nanyin was embarrassed by her words, but she was still wearing the swimsuit, and it really was unbearable.

After thinking it over, Song Nanyin simply took the swimsuit off. Since they’d already done it, there was no need to keep wearing it. More importantly… Liu Zhaoran was right. Doing it here really did… feel rather good…

“It seems Team Leader Song wants to continue too. You just insisted that I play the lewd one and say it out loud before you would stop being tsundere. Would you say that’s another kind of tsundere?”

“A perfectly good Black-Hearted Lotus, and it had to grow a mouth.” Song Nanyin ground her teeth. She felt that this Liu Zhaoran, with her two faces and that smug, needling look, could only be tolerated by Song Nanyin herself.

“Of course. If I didn’t have this mouth, Team Leader Song wouldn’t have felt so good. But it occurs to me that Team Leader Song has never used her mouth to help me. You’re not disgusted by me, are you?”

“What are you talking about? Can you not say such things in such a calm tone?” Song Nanyin had experienced Liu Zhaoran’s brazen words before, but she hadn’t expected her to put it that directly.

Song Nanyin’s face reddened, and she was shamefully shy. But even more shameful was that her body, which had just climaxed, actually grew wet at those words…

“Then prove it to me, Team Leader Song. Prove that you aren’t disgusted by me, and that you’re willing to use your mouth to help me.” As she spoke, Liu Zhaoran climbed up onto the pool’s edge together with Song Nanyin. The edge was paved with pebbles, soft enough that lying down wouldn’t hurt.

Liu Zhaoran straddled Song Nanyin, but facing away from her, arching up her pale, petite rear, while her head was right at the other woman’s crotch…

Song Nanyin hadn’t expected Liu Zhaoran to go this far. With that, her face was completely red.
