Head Doctor

This time I did see Dr. Marcus' dick began to stiffen and grow in his pants. It was the size of a fuckin firehose. Like me he was trying to keep it down, but it didn't work. "How big was the one that fucked you Kevin?" The way he said 'fuck' made my thighs vibrate. "How big was his dick?" But the way he said 'dick' made me want to cum on myself. 

"Maybe six and half, or seven inches."

"Is that so?" Dr. Marcus said. nodding his head. His dick throbbed wildly in his slacks. "You ever been fucked by an older man with a ten inch dick?" he asked. He started to stroke his cock through his pants. I started to do the same with mine. 

"No," I said staring at the imprint of his massive dick.

"Do you want to?" he asked coyly. 

"Hell yeah, I do."

Dr. Marcus looked at my crotch area. "Will you unzip your pants and let me see it, Kevin?"

I almost didn't believe that he asked me that. I licked my lips and tugged down my zipper. The head of my dick popped out.

"Take it all the way out your pants, Kevin," Dr. Marcus instructed. "I want to see the whole thing."

I stood and pulled my jeans and underwear down all the way down to my ankles. My eight and half inch dick was sticking out towards Dr. Marcus. He looked at my hard lustfully then at my eyes. "That's a nice dick, Kevin. Take off your shirt."

Even though the room was little too cool, I took off my shirt. My nipples were hard as well. I rubbed my flat stomach and my bulging chest. "Is this nice too, Doc?" 

"Come here," Dr. Marcus said. I took my shoes, socks, and jeans off. I walked over to him slowly, standing before, with my dick only a few inches away from his slightly open mouth. "Sit on my lap, Kevin."

I hopped on top of him and hooked my arms around the back of his neck. He pressed my chest to his face and began to lick my hot skin. His tongue on my hard nipples made me even hotter and harder. I ran my hands through his hair and closed my eyes. Dr. Marcus squeezed my ass, sliding his finger up and down my sweaty butt crack. I grinded my ass against his hard dick. I felt the head of his dick, through his silky slacks, trying to dig into my crack. I lowered my face to 
his and we kissed insanely. Our tongue searched each other's mouths completely, our spit combined, and his breath smelled so good and minty. Dr. Marcus nibbled on my bottom lip and poked at my asshole with his long middle finger. "

I love this ass," Dr. Marcus whispered. He slapped my butt hard. Still dry fucking me (but I could feel him precuming in his slacks), I unloosened his tie, unbuttoned his shirt and tore it open. His chest was just as muscular as mine, if not more. He had pretty, dark brown nipples. I sucked and bit them, licking them in quick circles. Climbing off of him, I went to my knees. I unbuttoned his slacks, and lowered the zipper, my heart beating super fast. Dr. Marcus lifted his hips up as I pulled his pants down to his knees. His dick looked way bigger than ten inches. It was nearly the size of my arm. I 
mashed my face into his balls and sniffed them. They smelled just as musty as I wanted them to. 

Dr. Marcus rubbed my hair as I licked his nuts. His sour smell made me even hotter. I licked underneath his dick, all the way up to the head. I licked around the head, while looking up into his eyes. And then I covered his whole, ten inch dick with my mouth. Dr. Marcus released a loud yowl and his hips quivered. He moved in and out of my mouth, pushing my head on his dick deeper and deeper down my throat. I sucked quickly, and then slowly, and then quickly again. "You're 
good at this," Dr. Marcus said.

I took his dick out of my mouth long enough to say, "I know." And then kept going. I sucked him off until my mouth was dry, but even then, his thick, slimy precum lubed my tongue again, and I continued for another five minutes or so. I took of his shiny black shoes, pulled off his dress socks and sniffed them. I loved the smell of his sweaty feet. I took three of his toes into my mouth at once, washing them with my tongue, licking between his sweaty toes, savoring the taste. I gave him a foot job for a little while longer until Dr. Marcus told me, "Get on my desk, Kevin. I wanna fuck you."

"Okay, Doc."

I pushed all of his things off his desk and climbed on top of it, on my hands and knees, with my ass waiting for him. "Such a pretty, round ass, Kevin," Dr. Marcus said.

"Smack it," I told him. 

Dr. Marcus slapped my ass really hard. I felt a heavy tingle throughout my whole body. He slapped it again and I whimpered. And then I felt one of his fingers poking at my ass; he took it out for a quick second, and when he put it back, It felt wet, and it slid easily into my asshole. He used his finger to play around with my hot, moist insides. The more I groaned and whimpered, the faster and harder he finger fucked me. "Do you like this, Kevin?"

"Yeah..." I groaned. 

Dr. Marcus shoved another finger in my ass, stretching the hole wider. "What about this?"

"Uh-huh..."

Dr. Marcus removed his fingers from my asshole and replaced them with his wet tongue. He pried my ass open so wide that it hurt, and shoved most of his face inside. Dr. Marcus dug around my ass with his nose, tongue, and lips and my whole body was sizzling with pleasure. He rubbed my balls as he ate my ass out and I could barely take it. Dr. Marcus removed his face from my ass, and shoved his dick inside me. I was filled with the best feeling pain I ever felt in my life. 

All ten inches of his dick entered my ass, and he gave me no mercy as he worked me out. Sweat dropped down my forehead onto his desk. I yelped and whimpered as he shoved his massive dick into me over and over without stopping. His dick was so far inside of me that I couldn't feel anything else but him, and I didn't want to feel anything else except for him. Dr. Marcus removed his dick and dried his precum on my hamstrings. I clinched my ass, but he pried it open and forced his dick back in again. My mouth opened wide. Dr. Marcus grabbed me roughly by the hips pulling me harder onto his dick, so much that my ass was pushing up against his hard stomach. His big hands moved up to my shoulders, and he continued to pull me back toward him, shoving it in harder and harder until I could feel the cum rise out of my balls, up my shaft, and come shooting out of my dick like water from a fire hydrant. I sprayed my thick whiteness all over his mahoghany desk Dr. Marcus was turned on by that. He made me lay on my back, on my own cum, and he spread my legs apart in the shape of the letter V, holding my feet, and plowed inside of me. I loved watching him fuck the shit out of me, the way his chest and abs rippled behind his open shirt, the way his beautiful, serious face twitched and his eyes shut tight as he entered my ass, the way his mouth was open and he tossed his head back. His stamina was unbelievable. 

Sweat poured down his face, down his tanned, muscular chest. "Keep fuckin me hard, doc," I told him. "Fuck me."
He shoved his dick deeper, and my upper body was hanging over the edge of his desk. Dr. Marcus pulled me back up and kept railing me.

"I'm ready, Kevin," Dr. Marcus said. He groaned loudly and bit his bottom lip. "Oh, I'm ready."

"Do it, Doc," I told him. "Cum in my ass."

"I will," he moaned. Dr. Marcus gave me one last powerful thrust, and I felt an explosive hotness burst inside of me. My insides were filled with his hot cream. I came again, and it hit Dr. Marcus right on his naked chest. He wiped it off with his fingers and licked them. "Taste good," he said. He kissed me for another three minutes after we came. I wiped the sweat the sweat off his body with my hands, licking them afterwards. Dr. Marcus licked the rest of the cum that had fallen on my stomach and chest. 

It only took us about three minutes to get dressed. When I looked at the clock on the wall, I saw that we had been going at it for over an hour. Dr. Marcus tucked his shirt into his pants and straightened his tie. I just wanted to rip his clothes and fuck him all over again. "I guess this session is over," he said. Dr. Marcus walked me to my to the door. As he opened the door, Dr. Marcus squeezed my ass and said, "See you next week, Kevin."

I squeezed his semi-hard dick through his pants and said, "I will."

"And get here early," Dr. Marcus said. "We're gonna need every minute."
