Asshole bud

The thick cock was slowly pulled away from the tight tender pussy, and the female pussy that was fucked bright red and slightly loose and squeezed out white semen. 

Qi Mu had just been marked and was extremely dependent on Gu Huaibi. At this time, he was like a puppy sniffing at the alpha.

His buttocks were gently spread open by the man, and his thick knuckles were dug into the asshole unceremoniously. The omega's own juice could finally flow out freely.

Gu Huaibi looked at the water output like a small faucet in surprise, and couldn't help but say: "How much water did you store in it?"

Qi Mu grunted, he seemed to be awake, but he was brought back by the rich pheromones in an instant. It felt really comfortable to have his little asshole dug, and even the big dick in front became hard.

Gu Huaibi looked at the beautiful cock that was one size smaller than his own. His heart moved. He lowered his head and took the thing into his mouth.

"En~~ It feels so comfortable..." Qi Mu was sucked in from the front, and the small asshole from the back was being pushed back and forth by two fingers. His hands were very free, so he consciously came to his chest, grabbed the two hard nipples, and pulled them repeatedly.

Gu Huaibi looked at him with raised eyebrows. Right now, the aloof male god of the college was now like a bitch, with his pussy open and his breasts rubbed, pitifully waiting to be fucked. This contrast made his dick, which had not softened, become even harder.

He gave Qi Mu two hard deepthroats, his hot mouth squeezing the sensitive glans, and Qi Mu instantly couldn't bear it and twisted his waist and screamed.

"Cough!" Gu Huaibi spit out the big thing and moved Qi Mu, who was all pink, so that he lay on the ground, holding his round buttocks with both hands. 

In the past, he felt that the buttocks wrapped under the suit pants were too plump. As an alpha, few people could have such a sexy big butt.

Now the ass was in his hand, and the watery asshole in the middle was waiting for his favor. Gu Huaibi straightened up, placed the thick meat blade in the middle of the butt crack, played with the buttocks a few times, and then inserted it against the hole.

The anus hole was filled with water, and it was devouring the invading giant without knowing enough. The folds were stretched until they were flat and white, like a steel cannon stuffed in a secret hole. 

Qi Mu was so satisfied that he even raised his buttocks to help insert the big cock deep into his body.

"So sexy." Gu Huaibi couldn't hold back and slapped the pair of big buttocks twice, leaving a few finger marks on the white and tender buttocks. Before Qi Mu struggled, he grabbed his waist and fucked his big cock unceremoniously.

"En en ah ah ah it's great~ My butt feels so comfortable. Go on, go faster, and fuck me again!" Qi Mu's physical strength is much better than that of ordinary omegas. He has just been fucked hard once, and now he still has plenty of energy. The consequence of being too tight is that Gu Huai will fuck the wall even harder. The cock will be pulled out until only the glans is left, and then the entire length is inserted until only the balls are left.

Qi Mu felt that his intestines were being fucked obediently by the opponent's big cock, and his anus was sucking the messy cock tightly, while his own hard cock slapped to the ground from time to time, and it didn't take long for him to squirt passionately.

The climax of the penis did not receive much attention during this sexual intercourse, and even the owner himself did not pay much attention to it. All he could think about was his asshole being fucked, and the man's generous kisses from time to time.

There were also some pheromones in the saliva. Every time Qi Mu was kissed, he would try his best to swallow the other person's fluids. Gu Huaibi pushed him away and felt that his tongue was numb from being sucked. The omega was in heat and he really couldn't be offended.

Gu Huaibi was thinking while fucking him, how compatible were his and Qi Mu's pheromones? 

The sweet smell constantly stimulated his brain, and his cock felt so good in his hole that he almost went to heaven. Normally, he didn't feel this way at all with his hand. Is this the pleasure of sex dominated by pheromones?

Ordinary male omegas have a reproductive cavity in their asshole, and behind the reproductive cavity is the mysterious and precious uterus. Normally, the alpha labeled omega will fuck into the reproductive cavity to form a knot and ejaculate, but Qi Mu's uterus was in the front female hole, and Gu Huaibi fucked the back hole for a long time without finding any special tunnel. On the contrary, Qi Mu had already had two or three orgasms in his ass.

Qi Mu had already reached his hand to his crotch, inserted his slender fingers into the woman's pussy, and pumped it passionately, causing the sticky semen to flow all over his hand. 

With a "bō" sound, Gu Huaibi pulled out his dick, slid it down, pulled his fingers apart, and fucked his big dick straight into the female cunt.

"En hmph~~ So good~~ Fuck me quickly, my womb is so itchy and empty~"

"Deeper! Big cock~~ Your big cock is fucking me... oh... so good! I want more, fucked my uterus with your big cock~~"

The egg-sized glans was stuffed into the uterus, trying to force it in and out like a pump. The originally narrow cervix was fucked to the point of being loose, and it was unable to push back the shaft from behind.

The tender buttocks were red from being hit. Gu Huaibi's own balls hit Qi Mu's buttocks. Looking down, he could see a thick black and red penis moving rapidly in and out of a cunt that had its labia turned out. His eyes became hot and he turned him over.

Qi Mu grabbed the clothes under him with both hands, and his legs were spread open. His thick cock pointed straight at his lower abdomen. The two testicles were much smaller because a lot of sperm was squeezed out, but the female cunt underneath was wide open, and the clitoris inside was sharp and hard.

Gu Huaibi saw it and decisively squeezed it, and saw Qi Mu screaming and crying as he climaxed.

The cunt was clamped tightly in an instant, and Gu Huaibi couldn't help but thrust hard and ejaculated all the semen inside.

"Hu! It feels so good..." Gu Huaibi pressed against him, and the tip of his nose was filled with the sweet scent of osmanthus. He licked the wound on the back of his neck, thinking about whether to take another bite.

Qi Mu was forced to switch to an omega, and he smelled so many aphrodisiacs, and was marked immediately after being inflowered. He entered estrus under various circumstances. Gu Huaibi's pheromones were highly matched to his, and now she was also seduced into estrus by him.

He still remembered that the two of them hadn't eaten for a long time, and they didn't want to be separated. Instead, he held him and moved them in the same position as the penis was inserted. He picked up his clothes and took out two tubes of nutrient solution from inside.

After drinking the nutrient solution, Gu Huaibi hugged him a few more times. Taking advantage of the pause, he groped for the exit of the palace and returned to the spaceship with him in his arms.

...

"Hmph... ah! You! I order you to pull out your stinky dick!"

Qi Mu was so angry that he just woke up yesterday. The memories of those days in heat came flooding back to him. He couldn't believe it to death that the slut in the palace who acted like a bitch after he was in heat was him!?

What's even worse is that he actually turned into an omega!

You must know that he is a rare top alpha! 

Elected as the alpha of the school for three consecutive years in the college! 

As a result, in just a few days, it inexplicably differentiated twice and turned into a soft and coquettish omega! 

How can he meet people like this?

And... Gu Huaibi actually marked him while he was unconscious, raped him with his dick, and even ejaculated inside him! 

Shameless! 

So shameless!

The first thing he did after he woke up was punch him, but his fist was soft and hit Gu Huaibi's chest like a flirt. The two of them stared at each other. Gu Huaibi's still hard cock was inserted into his vagina, and he immediately hugged him and fucked him from bottom to top.

Their estrus period was not over yet, but they had already passed the point of losing their minds, so Qi Mu had been resisting for the past two days, but Gu Huaibi refused to listen and forcefully hugged him and fucked him again and again.

When the last trace of the sticky smell disappeared and Qi Mu finally said goodbye to the estrus period, Gu Huaibi pulled out his dick and looked at the other person's body covered in liquid, his weak legs, and semen constantly flowing out of his two holes. 

He swallowed and said, "Shall I carry you to take a bath?"

Qi Mu held on to the bulkhead and said angrily: "No! I can do it myself!"

...

The school gave them two weeks to explore. As a result, they spent one week familiarizing themselves with the terrain and another week having sex. However, they gained nothing at the end of the trip.

Before leaving, Gu Huaibi brought back two bottles of something. Although Qi Mu didn't want to deal with him, he still asked, "What are these?"

Gu Huaibi: "The gas that made us go into heat that day."

Qi Mu: "What are you using this for? It's just an aphrodisiac, and there are plenty of them on the black market."

Gu Huaibi: "It shouldn't be a simple aphrodisiac. I suspect it has something to do with your secondary decomposition into omega."

Qi Mu immediately became excited because it was about his gender. He took one of the bottles and couldn't help but look at it again and again. 

Now I have an ordinary cylinder in my hand, and that gas is stored in it. What is it? 

Will it turn him into an omega?

If he says he doesn't feel uncomfortable or doesn't care, it's all lies. It will be uncomfortable for anyone who falls from the top of the food chain. 

And... he touched the back of his neck. He was marked by Gu Huaibi. Now he couldn't muster the energy to target Gu Huaibi. He even had to work hard to hold back his urge to throw himself into Gu Huaibi's arms.

It turns out that an omega will really be harsh on his alpha after being marked. In the past, he looked down on those omegas who were abandoned by alphas and sought life and death. Now it was him who knew how uncomfortable it was. He wished that Gu Huaibi would hold him twenty-four hours a day, bite the back of his neck and inject pheromones, it would be even better to insert a big dick into his cunt and shoot thick semen into his womb, which would be even more perfect!

He turned his head away with a cold face. Gu Huaibi thought he was still angry with him, and piloted the spaceship with some sadness. 

But the person in the passenger seat was just covering up, covering up his body that was secretly showing off.

Qi Mu knew very well that under his clean outer trousers, his pure cotton underwear was already wet.
