Chapter 4

The days after that first secret fuck blurred together into a haze of stolen touches and risky sex. Kai and I could not keep our hands off each other. Every time Leo left the apartment for work or errands, Kai would pin me against the wall, on the couch, or bent over the kitchen table. He fucked me hard and fast, knotting me deep, filling me until cum leaked down my legs for hours afterward. I started walking around with a constant ache in my hole, always slick and ready for him.

But the guilt never left. Every night when Leo came home smiling, kissing Kai hello like nothing was wrong, my stomach twisted. Leo was my best friend. We had known each other since college. He trusted me completely. And here I was, letting his Alpha breed me behind his back like some selfish whore.

Still, I could not stop.

It was Friday evening now. Leo had gone out with some coworkers for drinks after work. He texted us both that he would be home late, maybe around midnight. The second the message came through, Kai looked at me from across the living room with that dark, hungry stare I had come to crave.

“Bedroom. Now,” he said.

I did not argue. I walked straight to my room, heart racing, already feeling slick start to drip. Kai followed close behind, shutting the door and locking it even though we had the whole place to ourselves for hours.

He did not waste time with words. He grabbed me and kissed me hard, tongue pushing into my mouth while his hands yanked my clothes off. When I was naked, he pushed me onto the bed on my back and spread my legs wide.

“Look at you,” he growled, eyes fixed on my leaking hole. “Already so wet for me. You have been thinking about my cock all day, haven’t you?”

I nodded, cheeks burning. “Yes… I need it, Kai.”

He stripped fast, his thick cock springing free, already hard and leaking pre-cum. The knot at the base was starting to swell just from looking at me. He climbed between my legs and rubbed the head up and down my slick entrance, teasing.

“Beg for it,” he said.

“Please, Kai. Fuck me. Fill me up. I want your knot so bad.”

He pushed in slow at first, letting me feel every thick inch stretch me open. When he bottomed out, he groaned deep and started thrusting hard. The bed slammed against the wall with each stroke. I moaned loud, not caring anymore because Leo was not home.

“Fuck, your hole is perfect,” Kai panted. “So tight, so greedy. Milking my cock like it belongs to you.”

He fucked me deeper, angling his hips to hit that spot inside that made me see stars. I wrapped my legs around his waist, pulling him closer. His hand wrapped around my cock, stroking in time with his thrusts.

We were so lost in it that we did not hear the front door open.

Leo had come home early.

The bedroom door was locked, but the sounds we made were loud. Skin slapping, the bed creaking, my moans, Kai’s growls. Leo must have heard everything the second he stepped inside.

“Kai? Alex? You guys home?” Leo called out from the living room.

We both froze.

Kai’s cock was buried to the hilt inside me, knot halfway swollen. My hole clenched around him in panic, but that only made him groan and push deeper.

“Answer him,” Kai whispered, eyes gleaming with something dangerous. “Tell him we are watching a movie or something.”

I tried to steady my voice. “We are in my room… just hanging out.”

Leo’s footsteps came closer down the hall. “Hanging out? It sounds like you are wrestling in there. Everything okay?”

Kai started moving again. Slow, shallow thrusts that made wet sounds echo in the room. He put one hand over my mouth to keep me quiet while he fucked me right there with Leo standing outside the door.

“Yeah… fine,” I managed to say, voice shaking. “Just… playing a game.”

Leo laughed. “Sounds intense. I am going to take a shower. Join me in the living room after?”

“Sure,” I gasped as Kai hit that perfect spot again.

Leo’s footsteps moved away toward the bathroom. The sound of the shower turning on filled the apartment.

The second the water started running, Kai pulled his hand off my mouth and started pounding me for real. Hard, brutal thrusts that made me cry out.

“Such a good little liar,” he growled. “Talking to your best friend while my cock is stretching your hole. You love this risk, don’t you? Love knowing he could walk in any second and see me breeding you.”

I nodded frantically, tears of pleasure and shame running down my face. “Yes… fuck, Kai… harder.”

He gave it to me. He fucked me like he wanted to ruin me, hips slamming against my ass, knot swelling bigger with every stroke. The wet squelch of his cock moving through all the slick and cum was loud, but the shower noise covered it.

Kai leaned down and bit my neck, sucking a dark mark right where Leo would see if I did not cover it. “I am going to knot you now. Fill you so full that you will be leaking my cum the whole time we sit with Leo later.”

His knot popped inside me with a wet push. It stretched me wide, locking us together as hot cum flooded my insides in thick pulses. I came at the same time, shooting across my stomach while my hole milked every drop from him.

We stayed locked for long minutes, breathing hard. Kai kissed me slow and deep, his cock still twitching inside me.

When his knot finally went down enough, he pulled out carefully. A huge gush of cum poured out of me onto the sheets. He looked at it with satisfaction and scooped some up on his fingers, bringing it to my mouth.

“Clean it,” he ordered.

I sucked his fingers clean, tasting the mix of us.

We quickly cleaned up as best we could. I changed the sheets and sprayed air freshener to hide the heavy scent of sex and slick. Kai went to the living room first, acting normal.

When I joined them a few minutes later, Leo was sitting on the couch in fresh clothes, scrolling his phone. Kai sat beside him, one arm around Leo’s shoulders like the perfect boyfriend.

Leo smiled at me. “There you are. You look flushed. You sure you are okay?”

I sat down carefully on the single chair, feeling Kai’s warm cum still leaking slowly from my hole, soaking my new underwear. Every shift reminded me of what we just did.

“Yeah,” I said, forcing a smile. “Just got a little carried away with the game.”

Leo laughed and started telling us about his night out. Kai nodded along, but under the coffee table, his foot found mine again, rubbing slowly.

The conversation flowed normal, but the air felt thick with our secret. Leo had no idea his Alpha had just knotted his best friend minutes ago while he showered.

Later that night, when Leo went to bed, Kai stayed in the living room with me for a few more minutes. He pulled me close in the dark and whispered in my ear.

“Tomorrow Leo has that full day meeting. The second he leaves, I am bending you over and fucking you all day long. I want you dripping with my cum by the time he gets home.”

I shivered, already getting wet again.

This was getting dangerous.

But the more risk we took, the more I wanted him.

Leo was my best friend.

Kai was becoming my everything.

And I did not know how much longer I could keep pretending.
