“Oh, fuck,” I managed to say between clenched teeth as Dario pushed the last inch of his dick into me. It wasn’t his almost eight inches that made it a challenge. He had by far the thickest cock that had ever fucked me. I kept breathing deeply; there wasn’t pain, but there was discomfort.

Dario had stopped pushing because his entire dick was now inside me, and he wanted me to “acclimate”. That’s what he said, anyway. But I could tell he was squeezing his anus because his cock kept twitching inside me. That sensation made me want him to start pounding me.

“Just relax,” he whispered.

“With a baseball bat up my ass?” I smiled.

He smiled back; the same smile that got me to bring him back to my room. Just an hour ago we were in the chemistry lab.

We’d run a dozen titrations, and eight of them were within a few drops of each other. “I say we’ve got enough data. What do you think, Quent?”

Dario was the only person I knew who could shorten my name and not throw me into convulsions.

“I completely agree,” I told him. “Let’s get this cleaned up before we get kicked out.” I looked over at him. I wish I could tell him what I was really thinking. What was it about him that made my dick stiffen and fight to get out of my briefs? His jet black hair in a perfect haircut that framed his square face with that strong jaw? The cute cleft? His gorgeous sapphire blue eyes? Even his nose was perfect. And those perfect lips, the way they could pull back in a smile revealing dazzling white and straight teeth. What a fucking, sexy smile he had. And he was using it on me.

“Hey man,” he chuckled, “it’s Friday, I’m hungry and horny.”

“Well, Dario, I know how to solve one of those,” I smiled.

He reached his hand over and interlaced his fingers with mine. “Which one, Quentin?”

My lab partner of three weeks just made my cock lurch and spill precum into my underpants. I looked into his eyes. Was he teasing me, trying to get me to admit my secret? He moved closer to me; our interlaced fingers fell to our side, and he moved his hand to my crotch as his lips approached my ear. “I’m gay, Quent,” he whispered. His hand pushed against my cock. “I like you. I’ve been hoping you would give me a sign that you like me, too. But I just can’t wait any longer.”

I turned my head and kissed him. He kissed back. “My roommate went home for the weekend,” I told him. “Let’s get this stuff put away.

Thirty minutes later, he had me pushed against the locked door to my room. His mouth covered mine. Our tongues fought over dominion. I could feel his cock pushing against my thigh. My mind had a million thoughts running through it. Was he a top or a bottom? I hoped he was both because I wanted both. My hands wanted to feel his chest against mine. “Take your clothes off. I want to suck you.”

“But I want to suck you,” Dario countered.

“Then I’ll take mine off, too.” As I stood before him, both of us naked, I realized that he was sexier than I had imagined.

He reached out and touched me, his hand moving from my chest to my abs. “You are so fucking hot. Oh, I want you.” He fell to his knees and began to suck me. And he knew what he was doing. Although I considered my dick to be average, just a little over six inches. The few times I had been sucked, the guy had never been able to get all of me into his mouth. But Dario took my entire cock. The sensation as the last inch went in was incredible. He pulled off. “Grab my head and fuck my mouth.”

I’d seen that in videos, and it always looked uncomfortable for the guy on his knees, but if my new lover wanted it, how could I refuse. I grabbed his head and pushed and pulled my dick in and out. There was a strange popping sound as the last bit of my cock went in and out. Wow, it was intense. Dario sounded as though he were choking, but he didn’t push me away. I continued until the first urge to come began. I pulled out and sat in front of him. Spittle ran down his chin and his eyes looked bloodshot.

He wiped the spit away. “That was great.” He seemed out of breath, but he pushed me back and began to lick my balls and my taint. Then his tongue moved to my ass. His tongue ran across the surface of my hole and then the tip moved just inside. Prior to that night, I’d been fucked three times. One of those times was by a gay neighbor when I was a senior in high school. He was in his late twenties and in perfect shape. His fuck was by far the best. But Dario’s tongue surpassed that experience.

Dario sat back and kissed my nipples. “I’m on PrEP,” he said. “Always been negative and have always used a condom. Do you have some?”

“I’m on PrEP, too. I used my last condom the other day when I jerked off.

“Fuck. I need to be with you like I’ve never felt before.”

“I want to, but we shouldn’t. Dammit.”

“Put your clothes on.”

“What?” It wasn’t really a question.

“We’re going to go buy some; we’re going to buy a large box.” He kissed me again. “This is not a one-time deal.”

We got dressed in record time. My dick was rock hard, and the tip peeked out over my briefs. We hurried to Dario’s car, which turned out to be his family’s minivan.

“Sexy car, here, Dario,” I laughed.

“Fuck you. It runs, and it didn’t cost me anything.” He pulled out of the space just a little too quickly.

“Be careful. We don’t want to get stopped. But officer, we were just on our way to get condoms.”

“OK, you’re right,” he admitted.

“Hey, don’t these seats disappear into the floor?”

“Yeah, why?” He glanced back, and then an evil grin appeared on his face. “I guess it is a large area, but it’s not as comfortable as a bed.”

“I guess it could use some blankets. Maybe in the future.”

“Hey, how about Walmart?”

“You want to fuck me with discounted condoms?” I whined.

“If that’s all they have.” We both laughed, but I could tell by his bulge that he was still hard.

Even with obeying the speed limit, we made it back to the room in record time. I was half-naked before I had the door locked. Once I had my penis freed from its prison, I pulled Dario to the bed. Somehow, he was still holding the bag as he removed the last of his clothes. His cock had softened slightly but hardened as soon as I pulled him onto me.

“I think your dick is too big for my hole,” I teased.

“Oh, Quent, you’re a tease. You know that it’ll fit, and once I get inside you, I’m going to fuck you so hard that you’ll start giving birth to our children nine months from now.” He pushed my legs up and squirted some lube in my crack.

Usually, I found talk of one gay man impregnating another to be stupid and pointless, but when Dario said it, the anticipation of his penetration heightened. I became impatient as he put the condom on. I rubbed my fingers through the lubricant between cheeks and spread it on his dick as he unrolled it down his shaft. I lined him up with my hole, and he began to penetrate me.

“Oh, fuck,” I managed to say between clenched teeth as Dario pushed the last inch of his dick into me. It wasn’t his almost eight inches that made it a challenge. He had by far the thickest cock that had ever fucked me. I kept breathing deeply; there wasn’t pain, but there was discomfort.

Dario had stopped pushing because his entire dick was now inside me, and he wanted me to “acclimate”. That’s what he said, anyway. But I could tell he was squeezing his anus because his cock kept twitching inside me. That sensation made me want him to start pounding me.

“Just relax,” he whispered.

“With a baseball bat up my ass?” I smiled.

He began a rocking motion; his cock moved back and forth over my prostate with increasing frequency. As he moved faster, his breathing became more aggressive. I lifted my shoulders from the bed and licked his chin. “Yes, fuck, yes,” I growled. “Fuck me.” I lost sight of him as my eyes rolled back. “Oh, Dario, keep going.”

“Oh, baby. You’re so fucking tight.” He began to pump me with more force. “I love you, Quentin. You’re going to make me come, you sexy fuck.”

With those words, he began to slam his cock into me and grunt as he reached the hilt. His body tensed and spasmed four times, and four times, I felt the pressure inside my cunt increase. Then he stopped moving. His eyes stared at me. Seconds passed. He bent forward and fucked my mouth with his tongue. “I need you inside me.” He got onto his knees; his still rigid cock, with the condom full of cum, slipped out of me.

Dario handed me a condom before lubing his hole. “Fuck me from behind; just stick your dick in and give it to me. He stretched prone on the bed and I got between his legs. He reached back and pulled his cheeks apart. I found it difficult to hold myself up with one arm and line my dick up with his hole with my free hand. My dick found its way into him, and as I pushed deeper, he released his butt cheeks and pulled me in.

A rush swept over me. His warm tunnel held tightly to my dick. I pumped in and out. He lifted a shoulder and turned his head. I kissed him. “Shit yeah,” he grunted. “You’re hitting the spot.”

That comment just made me fuck him more forcefully. His face went down into the blanket. “Fuck, fuck, fuck,” he screamed into the bed. “Turn me over, turn me over.”

I pulled out and he rolled onto his back. I pushed my dick back into him. “Yes,” he growled, give me your fucking cock.”

“I love you, Dario.” I pulled out and then slammed back in.

“Fuck me, you bastard.”

I was sure there were tears in his eyes. He grabbed my head and pushed his tongue into my mouth. The taste of him increased my desire; I held his shoulders and dug my toes into the bed, giving me more leverage to pound his ass. With our mouths eagerly locked together, I pushed hard into him and unloaded into the condom.

Dario reached up and pushed my damp bangs from my eyes. I held the condom as I pulled out. I removed it and knotted the end before dropping it on the floor. I snuggled next to him. There were so many things that I wanted to say to him.

“When I first saw you, I wanted this; although I didn’t know how great this was going to be. I haven’t been with many guys; I haven’t even dated many guys, but I want to tell everyone you’re my guy. I want you to share this bed with me.”

“So if I say this was nothing but a great fuck, you’ll… what will you say or do?” Dario tilted his head and looked at me. “Quentin? Look at me, Quent.”

“You can’t mean that,” I said. “My heart would be crushed.”

I saw him bite his lip, and then he said, “I’ve been with a few more guys than you. I actually dated one guy for two years, and I know for certain that this was more than two horny guys. Tonight, you showed me things that I didn’t even dream existed, and you took me to a place where I never thought I’d be able to go. If I made a list of pros and cons for our being together, the only con I can think of is that you’re not rich. I always wanted to marry a rich man with a big dick. Your dick fits inside me perfectly.”

“Yours fit inside me perfectly,” I added.

“The taste of your lips, the smell of your body, your hair, everything; they just make me want you more. I want you; I want to be with you.”

“I feel the same way,” I told him. “But I have to be honest; there’s one thing you’re wrong about.”

I saw the smile disappear from his lips.

“My family owns a lot of real estate, and I’m actually very, very rich.”

Dario looked away and then turned back to me. “So, there aren’t any cons.” He smiled. “How long before you can fuck me again?”
