I never thought I'd find myself in this situation.

I was sitting in the living room with Alex, my sister's boyfriend. He was stretched out on the couch, one leg pulled up, the other resting casually on the floor. He was holding a beer in his hand, which had already warmed up a bit. A movie was playing on TV, but neither of us was really watching the screen. The atmosphere was... different than usual. Quiet. Tense. Maybe it was because we had been alone since my sister left on a week-long business trip. Maybe it was because Alex was in sweatpants and looked like he had just gotten out of the shower. Or maybe it was because I caught myself staring at his neck for too long. And his shoulders. And how his T-shirt fit him a little too well.

Finally, he cleared his throat, as if he was about to say something important.

“Matt?”

I turned to him, trying to look natural, even though my heart was racing.

“Hm?”

He hesitated. He looked at me with what could be called curiosity. Or... concern.

“What's it like... being gay?”

I didn't answer right away. The question hit me right in the gut, even though it was asked calmly. As if it were just a casual conversation about the weather. But it wasn't.

“That's a pretty general question,” I said slowly, cautiously. ”What exactly do you want to know?”

“I don't know.” He shrugged but didn't look away. ”What's it like... to be attracted to guys? What's it like from the inside? What turns you on?”

I laughed quietly, more out of embarrassment than amusement. I leaned back more comfortably on the sofa, trying to buy some time.

“I think it's the same as everyone else. You look at someone and you just... feel it. You start to be drawn to them. You notice their movements, their scent, their voice. You want to be close. To feel their touch. To kiss them. To be touched.”

He looked at me intently. Suddenly, this innocent topic was no longer so innocent.

“So... it's more about emotions? Or physicality?”

I sighed.

“Both. Sex without emotions can be fun. But when feelings come into it... it's like another dimension. Everything is more intense. Deeper. Stronger.”

Alex tilted his head, staring at me. His gaze was different. Not provocative. More pensive. But there was something else in it. Something that was starting to worry me.

“And... how is it from the other side?” he asked after a moment.

“What do you mean?”

“You know... being with someone. With a man. Physically. What's it like?”

I fell silent, feeling myself getting hot. Not because the question was strange. But because I didn't expect it from him.

I looked into his eyes, searching for some kind of clue.

“Are you talking about sex?”

He nodded.

“Yes. But... you know. Seriously. Out of curiosity.”

I clenched my hands on my knees. I felt I had to phrase this carefully.

“It depends on the people. On trust. Intimacy between men can be very intense. There's something raw about it, but also incredibly close. No one pretends. There are no roles.” Both guys know what they want. And when it happens... it's a damn powerful experience.

Alex didn't answer. He took a sip of beer and pushed the bottle aside.

“What if... I just wanted to see what it's like?”

I froze.

“What?”

He shrugged, but his voice was quiet.

“I'm curious. Just like that. No strings attached. Just to... see.”

I didn't know what to say. My heart was pounding in my chest. I had the feeling that something had just shifted between us. Something huge.

“Alex...” I began.

“I'm not saying I'm gay.” He cut me off. ”But... you're damn attractive. And if someone were going to show me that, I'd want it to be someone I trust.”

He fell silent, letting his words hang between us.

I felt my throat tighten. There was no longer just curiosity in Alex's eyes. There was something much deeper.

And then I realized that this conversation would change everything.

We sat in silence for a moment. The movie was still playing on TV, but neither of us was even pretending to watch it anymore. The air was thick, almost impossible to breathe. I looked at Alex as if I was seeing him for the first time—not through the lens of “my sister's boyfriend,” but as a man who had just opened a door for me that I never expected to see open.

“I agree,” Matt said.

I kissed him first, cautiously, slowly. Our lips met in a soft, searching kiss that grew deeper with every second. Alex sighed as if the touch was already breaking something inside him.

I slid down, kissing his neck, his collarbone, his chest. I could feel his body reacting—every muscle tense, every breath heavier.

When I reached his pants, I looked up at him questioningly. He nodded.

I slowly unzipped his fly and pulled him out. He was already hard, throbbing. I took him in my hand and leaned down, touching the tip with my tongue, circling it.

Alex moaned softly, resting his head against the wall behind him.

I took him into my mouth. Slowly, deeply. I could feel him pulsing against my tongue. I moved along his shaft, rhythmically, carefully.

“Matt...” he murmured, his voice hoarse with desire.

He liked it. Every moan was confirmation. I sucked him calmly, confidently, until his whole body trembled with tension.

At one point, he grabbed my shoulders and lifted me slightly.

“I want... to try more,” he said, and in his eyes burned a fire I hadn't seen there before.

He didn't wait. He knelt behind me, kissing my neck, my back, until finally his hands cupped my buttocks. He spread me open sensually, and then I felt his tongue. Wet, warm, determined.

I moaned loudly, surprised by the intensity. Alex didn't stop—he licked me for a long time, persistently, skillfully, as if he had done this before. I could feel his saliva, his breath, his tongue sliding into me, alternating with short, intense thrusts.

I held on to the pillow, trembling, grinding my hips in response.

“I want to go in,” he whispered. 

I was ready.

I felt the tip of his penis, warm and slippery with saliva. He slid into me slowly, his breath tense. My scream broke the silence of the room, but not out of fear—out of pleasure, out of that incomprehensible mixture of pain and desire. He stopped, giving me time to get used to it. Then he moved gently.

With each movement, he filled me more, deeper.

I could hear him moaning—a low, drawn-out sound, full of delight. Each thrust was precise, strong, complete. He thrust deep inside me and stayed there for a moment, trembling.

“Matt...” he whispered. ”You're so... tight, warm...”

I couldn't answer. My body spoke for me.

His pace quickened. Our bodies collided with a soft slap. I felt his breathing become shallower, his movements more desperate.

And then he froze.

He let out a throaty moan, almost drawn out, and then I felt warmth... spreading through me slowly, unstoppably. His breath roared in my ear, heavy, ragged, full of relief and something that resembled delight.

He filled me completely, deeply, as if at that moment he had given me everything he had.

He collapsed on top of me, wrapping his arms around me.

And then he said something that stayed with me all night:

“Matt... that was great. And... I think I'd like to do it again.”
