It was my senior year in high school, and I turned eighteen the summer before. I worked hard and took extra classes, which gave me enough credits to graduate a year early. But due to some stupid district bylaws, I had to take two classes to graduate, and they had to be taken in my senior year.

My days were filled with electives until my final mandatory class. I bitched and moaned about my situation in pure teenage fashion. It was these stupid bylaws that put me in the path of Kim, or as she liked to be called in art class, Ms. Kim.

Ms. Kim was the only thing that made my last year manageable. She was in her early 30s standing 5 feet 6 inches tall, with long red hair, pale freckled skin, a full, curvy body that housed large DD tits, and a perfectly round ass. The kind of ass you could rest a drink on and not spill. Ms. Kim’s class was my first class of the day, bright and early in the morning. I was always very eager to get to class, often early just so I could ogle her beautiful form.

I found myself asking lots of questions just to have her near me, and I could get a whiff of how intoxicating she smelled. It was a mixture of honey and desire that emanated from her. She often rested her hand on my back or shoulder, which sent shockwaves to my always aroused teenage cock.

The days passed, and Ms. Kim became the subject of my daily masturbation sessions. Every day after school, I would find myself rushing to my room, the bathroom, or the barn for chores if my parents caught me before I reached my destination. Ms. Kim flooded my mind as I would slowly stroke my cock to a mind-blowing orgasm.

Every day in art class I had another question, but with each question her touch lingered a bit longer. Spurring me on to test the boundaries of Ms. Kim by grazing her side as she bent down to answer my questions. Each day her shirt was buttoned less and her clothes were tighter.

As the term was nearing its end, Ms. Kim would press her body against mine as she rubbed my shoulder. She bent just far enough so I could clearly see her beautiful cleavage smashed in whatever sexy lace bra she wore that day.

On the final day of the semester, Ms. Kim handed out a piece of paper that had our final grades written on it. Like all teenagers, our responses were a combination of sighs of relief and excitement. When I looked at my paper, all that was on it was, "See me after class," in bright red ink. My heart dropped at the thought of a failing grade. However, my body felt a shock that radiated to my cock, which began to grow hard. I quickly forgot about the chance of a failing grade and basked in thoughts of being alone with Ms. Kim.

I sat as patiently as any hormone-driven teenager could, watching the clock on the wall tick by second by second until the bell finally rang. The sounds of students gathering their books and bolting for the door had my pulse racing as I sat quietly at my desk. The last student exited the door as Ms. Kim got up from her desk and headed to the door to close and lock it.

I watched as her hips swayed and her ass moved up and down in her tight, knee-length black skirt. My eyes were drawn to her white blouse, from which I could make out a glimpse of black from her bra. My heart skipped a beat and my cock throbbed as Ms. Kim turned towards me. Her eyes sparkled as light from the window hit them. She gracefully strolled towards me, and my hands began to shake. I gulped as she stopped in front of my desk; she placed her hands flat on the desktop and bent over at the waist. My eyes widened and my mouth dropped open as her cleavage came into full view inches from my face. Ms. Kim’s large, round DD breasts were being pushed together with the sexiest black lace bra.

Ms. Kim smirked as she watched me ogle her tits, the juvenile action caused her nipples to harden. She looked deep into my eyes, my cock throbbed, and I nearly lost control right there at the desk.

Ms. Kim said, “I have not settled on your final grade because you have been distracted in class and needed to ask a lot of questions on every subject matter. How are we going to determine your grade?”

I replied, “Extra credit.”

Ms. Kim grinned devilishly and said, “What a wonderful idea. Meet me at my car in the parking lot after school.”

I nodded in compliance as she stood up and ran her hand across my face and down my chest. Ms. Kim smirked and motioned for me to leave. I grabbed my books, covering my now fully engorged cock, and beelined for the door. Forgetting she locked the door, I heard the clicking of her heels coming up behind me. My hands trembled as I felt Ms. Kim’s DD tits pressed against my back as she reached around me to unlock the door. When she withdrew her hand, she grazed my cock through my pants. I felt her nipples harden and press against my back.

Ms. Kim whispered in my ear, “Don’t forget to meet me in the parking lot after school. So you can get started on your extra credit.”

I turned the door handle and quickly headed to my next class. I went through the rest of the day in a haze. Constantly looking at the clock, hoping it said 3:15 pm. When the bell finally rang, I nearly flew from my desk and headed straight for the parking lot.

I sat in my Chevy pickup, hoping that Ms. Kim wasn’t messing with me. I kept replaying the morning's proceedings over and over in my head: how her skin looked smooth and silky; how her ass swayed as she walked to lock the door; and how her hard nipples felt against my back, sending shivers down my spine and causing my cock to throb.

I heard a tap on my window, and there stood Ms. Kim looking like a curvy red-headed goddess. I rolled down my window and tried to look confident.

Ms. Kim said, "Follow me.”

I stared as she glided across the parking lot to her car. I was mesmerized by her air of authority and confidence. I followed closely as we drove out of town and down the back roads before we arrived at a small farmhouse. Ms. Kim waved me out of my Chevy. I quickly jumped out and was next to her in seconds.

We entered the small farmhouse as she pointed to the couch. I sat down as she disappeared into a backroom. She emerged; her hair was down, and she had removed her shoes. Ms. Kim sat next to me and placed her hand on my thigh. I gasped at her touch, and my cock responded in turn.

Ms. Kim looked into my eyes and said, “Are you ready for your extra credit?”

I was so excited I could not speak; I just nodded my head. My hands were shaking as she began rubbing my thigh.

Ms. Kim said, “Stand up and take your shirt off.”

I stood up and started to slide my shirt over my head when I felt a soft, warm hand rub across my stomach. Before I could get my shirt off, Ms. Kim was kissing and licking my stomach. I moaned in pleasure as I continued to remove my shirt. When I had cleared my head from my shirt, she was standing face-to-face with me. Her hand traced my chest and stomach as her other hand rubbed my cock through my jeans. Ms. Kim kissed my chest one more time before stepping back and starting to undo her white blouse. Button by button she slowly uncovered her DD tits that were still encased in her black silk bra. She dropped her blouse as I finally got a glimpse of her soft, white belly.

I gasped and said, “Ms. Kim, I have been imagining this since the first day of class. You are so hot that I rub my cock every day after school to thoughts and images of you.”

Ms. Kim smirked and said, “Call me Kim because we are about to get to know each other a whole lot better.”

She looked into my eyes as she unclasped her black lace bra, freeing her large, milky white tits. Her nipples were the size of erasers surrounded by 2-inch pink areolas. Her skin was so pale I could see the blue veins across her breathtaking DD tits. My mouth watered at the sight of Ms. Kim topless.

She asked, “Are they everything you imagined?”

I could not speak; all I could do was nod in agreement. Ms. Kim dropped to her knees and started to undo my pants. She slid them down with my boxers in one swift pull. My throbbing cock sprang free. Ms. Kim quickly wrapped her hand around the shaft and started to stroke my now over-engorged cock. She placed her other hand on my stomach as she continued to stroke my cock until she could see the precum start to glisten from the tip. She stroked as she licked the precum from the tip of my cock.

I moaned, “Kim, that is fucking amazing.”

She sucked on just the head and stroked my cock a few more times before stopping.

She looked up and said, “It’s much bigger than I imagined.”

Before long she was sucking the head of my cock back into her wet mouth. My knees were beginning to shake, and my moans became louder. Then, all of a sudden, Ms. Kim stopped and stood up. She pushed me back on the couch, and she turned around so her large, beautiful ass was facing me. Ms. Kim slowly unzipped her tight black skirt and began to slide it down over her hips. I was mesmerized when her round, full ass was in view. She bent over at the waist as she continued to slide the skirt all the way off. As I watched her strip, it dawned on me: she didn’t have on any panties; I could see her pink, puffy pussy lips. My cock jerked at the sight of her wet pink labia.

Ms. Kim stood up, turned towards me, and quickly closed the distance between her and the couch. She stood in front of me, rubbing her large tits with one hand as the other went straight between her thighs. My cock twitched at the sight of this curvy goddess in front of me.

Ms. Kim said, “I am going to ride that big, hard, youthful cock until I think you have earned an A.”

Ms. Kim straddled me on the couch as she grabbed my cock and guided it to her wet, hot pussy opening. She slowly lowered herself down until the head of my throbbing cock split her puffy pussy lips framed in a well-trimmed tuft of red pubic hair. My throbbing cock slid slowly into her tight, wet cunt, inch by inch. Ms. Kim moaned in pure ecstasy as my cock disappeared into her wanting cunt.

Within minutes, I was deep in her lovely, tight cunt, and her large, round ass came to rest on my lap. She wrapped her arms around my neck and pulled my head to her chest as I sucked one of her nipples into my mouth. I licked and sucked on her nipples as she started to grind and rock her hips on my raging hard cock. I forcefully grabbed her hips to help her grind on me. Each thrust forward by Ms. Kim put my cock deeper and deeper into her until I felt the tip of my cock hit her cervix.

Ms. Kim screamed in pleasure as her pussy erupted in wave after wave of cum and orgasms. She rocked harder as the pure pleasure caused me to release her nipple and scream in pleasure, digging my fingertips into her soft milk-white flesh.

I said, “Holy fuck, Ms. Kim, your pussy is so tight.”

These words just spurred her on as she rolled her hips faster and harder until she broke out in spasm after spasm. Her pussy clenched and rippled around my cock. I could feel her juices run along my cock and start to puddle in my lap. I grabbed her hips tighter, leaving red finger impressions on her skin as I start to thrust up to meet the rhythm of her rocking.

She screamed, “That is it, just like that, Joe. Don’t stop.”

Within minutes Ms. Kim was shaking and gasping for air in between her screams of, "God, yes!" I continued my assault on this curvy goddess's pussy until sweat was dripping down both our bodies. Right as I felt my cock twitch and balls tighten, Ms. Kim slid off my cock which was dripping wet from her juices. She slowly stood up on her shaky legs.

Ms. Kim looked at me with her seductive emerald eyes and said, “I need you to fuck me from behind. I need to feel the full length of that hard, young cock."

She proceeded to get on all fours on the floor. Her large, round ass sticking up in the air, I got on the floor behind her. I grabbed her soft ass cheeks and spread them as I took my tongue and slid it along her wet, gaping pussy, causing goosebumps to erupt across her skin. I licked and sucked on her cunt from behind for a few minutes as I admired her lovely ass.

Ms. Kim moaned and asked, “Oh my, where did you learn how to do that?”

To answer her I drove my tongue into her pussy opening and fucked her with my tongue. Ms. Kim erupted in a wave of uncontrollable spasms, her pussy gushing juices onto my face. As her spasms subsided, I grabbed my cock and aligned the head with her pussy opening. It looked like a flower coming into bloom as I slid my cock in with no resistance. In one hard thrust, I buried my cock in her as my hips collided with her ass, making a thunderous clapping sound. I paused for a moment before sliding my cock out and driving back in as hard as I could. Ms. Kim screamed in pleasure as my thrusts got harder and faster, causing her ass to ripple as my hips collided with her ass. It didn’t take long before she was twitching, and her pussy clenched on my cock. That’s all it took to push me over the edge, and I exploded like a tree being struck by lightning. I shot stream after stream of my thick cum deep in Ms. Kim's tight, wet pussy. As the last stream shot from my cock, I collapsed onto her back, covered in sweat, panting to regain my breath. After a few minutes, my softening cock slid out of her cum-drenched pussy.

Ms. Kim turned around and said, “You definitely earn an A. Now, hurry up and get home before your parents wonder where you are.”

I did as Ms. Kim said and gathered my clothes and headed for the door as she lay naked on the floor. My extra credit with, as I now call her, Kim, continued once a week until I graduated. Kim opened up my mind to the wonders of sex with a curvy woman and expanded my skills as a lover. After leaving my hometown, I would always visit Kim when I came back into town, but those are tales for another time.
