Kai POV

Surrender had never felt so sweet. When Avery told me I didn't need to hold back, that I could do what I wanted, I felt liberated in a way that was almost surreal. Whether it was my rut, or his heat, or an imprint, one thing was clear. We were tied together by fate, and there was an odd sense of security in that. He was the embodiment of a future that I had never dared to dream of having, and he was right before me, giving it to me.

 Avery had gotten back onto the bed, and he called me over. His pheromones filled every space of this apartment, and they embraced me, beckoning me over to him. Once I decided to stop holding back my pheromones also poured out of me, and I found myself wanting to do things I never thought of before. Tonight was my first time with an omega, and the things I found myself doing were foreign to me.

 Starting at his feet I licked his body. I wanted to taste every inch of him. I could hear his shaky breath as I went to work, and when I got to his inner thigh, I decided to bite him. His skin was so pale that I could notice him blushing no matter where I looked, and the thought of leaving a mark here excited me more than I thought possible. He let out a small whimper, followed by a moan when I started lapping over the impression I left. I love this.

 His ass was red, and I could see him twitching both in the front and back, and the thought that all of this was mine to do with as I pleased was exhilarating. I positioned myself against him, and after I leaned down to kiss him, I entered him completely.

 "Ahhhh! Ngh, hmmm, Kai! Yes, that feels good!"

 I started moving faster upon hearing that, but it still didn't feel like I was deep enough. Wrapping my arms around Avery, I picked him up, and then sat back on my heels while holding him.

 "W-wait! This position, it's a little…"

 "Shhhh, Just hold on tight. It'll be fine."

 Avery held on to the back of my neck so tight that I wouldn't have been surprised if he left a mark, and that thought alone turned me on even more. His legs were wrapped around me, and I could feel his thighs twitching every time I moved inside him. I had each of my hands holding underneath his legs, and once I found a good rhythm I started thrusting as deep as I could. The familiar rush down my body that I felt earlier returned, and I started throbbing inside him to the point it was almost painful.

 "Just remember, you said I could." I wasn't sure if he understood what I meant, but he nodded his head against my chest.

 I moved my arms to wrap around his lower back, and I lowered my head to nuzzle it in the side of his neck. He smells so good here. It was only a few seconds after that I could feel myself growing inside him. He started wriggling in my grasp, and his moans grew louder and louder.

 "KAI! Wait, what is this? I don't like this, stop, please!"

 My heart dropped when he said that. I told him earlier that his body wasn't prepared to experience this, but he insisted it was fine. Fuck.

 "I can't stop, Avery. If I take it now, it will only hurt you worse. Just hang in there."

 "Kai, it's still getting bigger! Ngh, haa, haa"

 "Just focus on me, it'll be okay. It will feel a little better soon."

 Avery slowly started rocking his hips, and his moans were a mixture of pain and pleasure. I decided to try to make him feel as good and comfortable as possible, so I slowly laid myself back on the bed so that he was straddling my waist.

 "Does this… Feel a little more comfortable?"

 He nodded his head and kept grinding against me, and I took my hand and started stroking him as he did so. I could sense that he was feeling more pleasure than pain now, and it wasn't much longer until I had fully grown inside him. Almost simultaneously, Avery came onto my torso while I released inside of him. The experience itself was something I could have never imagined. The pleasure lasted ten times as long, and it felt like I wouldn't ever stop cumming.

 It started to leak out of Avery once I began returning to my normal size, and something inside of me made me want to keep it inside him for as long as possible. When it seemed like it was safe to move more freely, I sat up and turned so that he was on the bed, and I was above him. I rolled him onto his stomach and lifted his hips, then frantically entered him again to try to prevent any more from spilling out.

 "What a-are ahhh you doing?"

 "…I don't know."

 It was true. I didn't have any real reason for doing this, Avery probably thought that I was just ready to go again. Which, I mean, wasn't completely false. Moving inside him felt like heaven on earth, and I never wanted this moment to end. Rather, I was afraid of what would happen when it did end. Looking down at his back I noticed that his hair had fully moved over his shoulder, and the nape of his neck was fully exposed.

 "I want to mark you."

 He nodded his head, and I lowered his hips slightly so that I wouldn't hurt his waist by leaning over his back. His entire body was tensing up and it looked as though he also lost himself to the pleasure. Wrapping one arm around his waist and my other hand loosely around his throat, I nuzzled my head against his back. I began licking him slowly, from between his shoulders and up to his nape. He smelled so good here, and the thought that he would be mine forever if I just opened my mouth overwhelmed me.

 I started with soft kisses, and then started sucking his skin. Eventually I couldn't take it any longer, and after opening my mouth as wide as I could I sank my teeth into him. Avery cried out and came as soon as my teeth made contact. It felt so good to mark him, he was now my omega. He was mine to protect, and to love, and support. After removing my mouth from the back of his neck I tapped my forehead to the back of his head, and a moment later I finished inside of him again.

 The sun started coming up, and it wasn't until I saw the light break through the kitchen window and shine on the wall behind my bed that I realized we had been going at it all night. My rut seemed to have subsided, and that moment of clarity made me realize how much of our pheromones we released throughout the night.

Glancing back down at Avery his face looked so peaceful, and it was clear that he had fallen asleep. His entire body was a mess, from hickeys to bite marks, and there was even a small amount of blood threatening to trickle down from where I had just marked him. His hair was a knotted mess, and he was covered in a mixture of sweat, saliva, and cum.

Sliding my arms underneath him, I picked him up and carried him to the bathroom. I managed to pour some soap in and turn the water to the bath on, and once it felt warm on my toes, I got in with him in my arms. This was the first time I ever used the bathtub in the apartment, but I was extremely grateful for it. The water came up rather high on Avery, but I figured I should soak as much of his body as possible in the water.

Alternating hands I rubbed up and down his petite frame, trying to clean him up as much as I could. I supported his head while getting his hair wet, and while this was a far cry from a proper bath or shower it was at least better than nothing. Next I used my fingers to try cleaning him out the best I could, and while he made small moans here and there he didn't wake up. He felt swollen, and while I got a decent amount out of him I wasn't sure if it was everything.

 When we were both freshened up a little bit, I wrapped his hair the best I could with a towel, draped a towel over his body, and set him on the couch while I changed my bedding. Once that was done, I finished drying him off the best I could, tossed the towels to the floor, and carried him back to the bed. I laid him down and closed the curtains around the bed before also crawling in next to him. Before I had finished settling under the blanket, Avery had shifted closer to me. How can one person be this adorable?

 Whether it was the effect of me marking him and us becoming bonded, or if I would have felt this way regardless, I don't know. What I do know is that a feeling of pure bliss set up roots deep inside me, and it seemed like nothing else mattered but him. I wrapped my arms around him and pulled him into my chest, and I was almost beside myself at the genuine joy I felt just listening to him breathe and watching him sleep. I had no clue how long I stayed awake observing him like that, but at some point my eyes closed and I drifted off into the best sleep I ever had, with my omega in my arms.
