Secondary differentiation, estrus in situ, seeking flowering

The corridor was very long, and the two of them walked for more than an hour before reaching the end. At the end was a closed door, which slowly opened after they arrived.

"It's like an automatic sensing device in a shopping mall, but what kind of energy does it rely on to keep working? It can still run after such a long time." Gu Huaibi said to himself and then walked in decisively.

"Hey! Are you going in like this?" Qi Mu stopped him.

"Otherwise? Are you going to walk back again? And then climb up from where we fell?"

Indeed, even if he brought the nano-rope, he felt like he couldn't reach the exit.

As soon as the two of them entered, the door closed with a bang. Qi Mu quickly pushed it without any reaction, for fear that they would go out again.

"Damn it! It can't be opened!"

At this moment, colorful lights suddenly flashed around them. Before the two of them had time to take a closer look, they heard a very mechanical sound coming from the center.

"Under detection... Top alpha... in line with... Zi... Zi... project activation... project activation... project activation completed, release gas."

After the words fell, eight pipes protruded from the corners of the wall, and violent white smoke spewed out from them, quickly blending with the air.

"Hold your breath!" Gu Huaibi yelled, and Qi Mu knew what to do without him reminding him.

Time passed by, and their alpha's physical fitness was beyond ordinary people, and they could hold their breath for up to twenty minutes! 

But the palace made it clear that they were required to inhale the gas, and the emission of white smoke did not stop for twenty minutes.

After another five minutes, the two of them couldn't hold on any longer, so they relaxed their mouths and noses and began to take a deep breath of air.

"It's weird, I really want to..." Qi Mu shook his head, sweat quickly broke out on his forehead. He pressed his hand on his crotch, and the originally quiet place suddenly tended to rise.

He turned to look at Gu Huaibi and found that the other party was not in good condition. Gu Huaibi came over and said in a hurry: "This gas seems to have an aphrodisiac effect. I seem to be about to go into heat."

"Me, me too." Qi Mu was already a little confused. He even moved his hand and pointed at the small tent that had been put up. "It... stood up by itself."

If one of them is an omega, then the two of them have already started to have sex fiercely, but unfortunately, they are both alphas. The same aggressive pheromones in estrus are incompatible with each other. Whenever they get close to each other, they will be extremely uncomfortable psychologically and physically.

"Stay away from me... don't come over. I don't like your smell." Qi Mu found a corner and sat down by himself. His resistance was not as good as Gu Huaibi's. At this time, he took off his pants and tried to solve it with his hands. Gu Huaibi looked at him and swallowed. He was about to lose his mind. Driven by desire, he felt that Qi Mu's pheromones were not that unpleasant.

According to legend, a top alpha will appear every three hundred years. When in heat, he can use his powerful pheromones to transform other alphas into omegas that can accept him.

The two of them each sat in a corner, stroking their erect penises in a daze. After another half an hour, the tube was finally retracted, and the aphrodisiac gas in the air reached its peak. Gu Huaibi stood up and walked steadily towards another living person in the palace.

Qi Mu was not clear-headed, but he still had the instinct to avoid danger. He shrank toward the corner again, and when he raised his head, Gu Huaibi was already standing in front of him, with the rich sandalwood fragrance surrounding him. He wanted to emit his own pheromones to resist but found that his scent was suppressed and he could only live in the corner.

"Go away..."

Gu Huaibi's big cock was facing the top of his head, and a trace of semen flowed from the eye at the top, one drop, two drops... slowly falling to the ground.

Qi Mu was breathing rapidly, and the two of them were in a stalemate for about a minute. The person sitting suddenly covered the back of his neck, coughed hard several times, let out a painful groan, and panted again like a person who had just been relieved. 

Qi Mu felt that he had completed a transformation. The unpleasant alpha smell that was suppressing him a second ago suddenly became refreshing. He inhaled the surrounding smell into his nose vigorously. His originally erect penis became harder and thicker, and his hard nipples could be seen through his half-open shirt.

"It smells... it smells so good..." Like a bee that found a flower, he knelt in front of Gu Huaibi, held the other person's buttocks with both hands, opened his mouth eagerly, and licked the glans with his red tongue.

The semen at the glans relieved his heat. He was like a traveler who found water in the desert. He opened his mouth and took the entire egg-sized glans into his mouth. Gu Huaibi exclaimed in pleasure.

The influence of this gas on him was much lighter than that of Qi Mu. After the other party put his dick into his mouth to relieve it, he regained his senses within five minutes. Although he was still in estrus, he could always think, right?

"Qi Mu?" He looked at Qi Mu in surprise, who was sucking his penis like a hungry bitch, and was even more surprised at how the other person suddenly turned into an omega.

That's right, the osmanthus-flavored alpha pheromone that originally made him feel uncomfortable had transformed into a gentle, tolerant, and sweet omega pheromone. Although it still smelled like osmanthus, it was completely different from the feeling it gave him before.

Reasonably, he told him that he should push Qi Mu away, otherwise, when the two of them wake up, they will not be able to face each other. 

But in terms of action, no, not at all.

"Ah... oh... it feels so good... your cock is so big... it's so full... it's so comfortable... it's all filled up... faster... more..."

"Brother Mu! You're so good! Your cunt... Ha... bite me tightly, do you like my cock... Oh, you are my bitch, take it so deep... Your uterine opening keeps biting my glans!"

"I like it~~ ah... I really like Brother Huaibi's big cock! It's so good! Fucked Brother Mu badly~~ Insert it into my womb! Mark me!"

Gu Huaibi's abdomen touched Qi Mu's huge cock, which was considered outstanding among alphas. Qi Mu's cock is also straight and thick, with a round and full glans, and the eyes will open and close at the same time as the hole is fucked. If it weren't for Qi Mu becoming an omega, this cock would probably become a fetish that many betas and omegas yearn for in the future.

It's just... this will never be possible. Qi Mu, who became an omega, will forever lose the ability to impregnate others. Even in the future, he can only be sexually excited by the marked person!

Gu Huaibi took Qi Mu's upper body, pressed his head on his chest, looked at the sweaty white neck, lowered his head, and opened his mouth——bite him in one bite!

At the same time, the glans in the vagina finally opened the mouth of the uterus, and the last part of the cock was completely inserted into the pussy, and the area just below the glans that had just entered the uterus began to swell into a knot. After confirming that the prey was locked, the sperm was opened wide and began to spray wildly into the small uterus!

The glands on the back of the neck were bitten and injected with pheromones, and the semen was violently ejaculated into the uterus. Qi Mu rolled his eyes in pleasure, bent his body slightly, and his thick cock jumped in the air, and two streams of semen were ejected in succession.

The thick semen was ejaculated on the ground, and no one paid attention to it. The tall alpha was holding him for irrigation. 

The ejaculation time and amount of alphas are much longer than that of omegas, especially the first knot-marked ejaculation. Some alphas can take up to two minutes to ejaculate. 

As for an incredible figure like Gu Huaibi who could force a top alpha into an omega... Thank God, five minutes later he finally hugged Qi Mu and started kissing him carefully.

The previous thick smoke had been emitted for a full hour and a half. After Qi Mu successfully transformed into an omega, the palace turned on the air purification device, but it would take some time for the aphrodisiac to be completely replaced, so not long after, Qi Mu began to hug Gu Huaibi impatiently and began to rub against it.

Gu Huaibi poked Qi Mu's belly, which was swollen from eating his first semen. The other person's body was filled with his pheromone. He was like a lion who had obtained the entire grassland, and he was in a great mood.

"Let your cunt rest for a while. If your asshole is not fucked, the water will flow out no matter how long it lasts."
