I’ve always enjoyed the smell of a basketball court. It was odd for me to like the scent; sweat, rubber, and floor polish, but for some reason I did. It made me want to run, want to exercise. I patiently sat on the bleachers waiting for Coach to come in, thinking over the events that brought me here.
I joined the basketball team two years ago, it was fun but not for me. Last year I decided to try volleyball instead, playing as the opposite hitter. It was fun but again didn’t feel like it fit me. I always had admired the spiker on the team. I admired the way she would leap up and hit the ball with perfect precision, how in tune she was with the setter. I envied it.
I worked hard all summer for the chance to try being a spiker and after much effort, I was selected for the position. Coach Oh said I just needed a little fine-tuning.
We had worked together for the past few weeks during practices to build up needed muscles. Yet even after all that work, my vertical jump wasn’t as high as it needed to be and he offered to help privately as well.
Coach Oh walked into the gym, smiling widely as he set down some papers, “You’re here already?” He asked, taking off his work shoes to put on sneakers. I nodded silently at him, standing up stretching my arms.
Coach Oh walked onto the court, me trailing after him, “Can you stand with your legs shoulder wide and arms at your side?” He asked and I complied. He looked over me for a moment, concentration furrowing his brows, “I can’t see your body well with all those clothes.“ He commented, causing me to flush slightly.
“You want me strip? So you could see more clearly of course.” I asked tentatively, looking down at my baggy shirt and basketball shorts.
“It would be nice so I could have a better look,” He said gently, trailing off, “but you don’t have to of course!” He assured. I took a deep sigh before pulling my shirt off, shorts following. I got back in position and cleared my throat, catching the attention of Coach Oh who was awkwardly looking at the ceiling.
He looked me over, eyes trailing over my sports bra, to my stomach, then past my boy-shorts, “Turn around.” He said, voice a bit pained. I turned around, feeling his hot gaze travel across my ass, “We’ll workout like this to show what definition you have.” I nodded at him, turning back to face him. He clapped his hands, “Okay then, let’s start out warm up!”
I began to do sprints across the court, sweat building and heartbeat increasing. The lack of clothes wasn’t embarrassing but a relief as time went on, my muscles warming wonderfully as my body heated. I came to a stop and looked at Coach Oh, the five minutes ending.
He nodded at me approvingly, “Today we’re not doing our normal dumbbell squats, we’re seeing how many shallow squats you can do a minute. It will be a good starting point to see how much stamina you have and how strong the muscles are. Sound good?” He asked, sitting down on one of the benches.
“Sounds fine.” I said before starting my squats.
Coach stopped me immediately, “You’re going to low for shallow squats, come over here.” he said, motioning for me to come closer, “Do them over me, when you hit my lap you come up.” he explained. I gulped before beginning the squats, turning around so he couldn’t see me blushing.
Coach Oh was very attractive for a teacher- or a person in general for that matter. Luckily, straining activities distracted me from the strong urge to jump his bones. Fucking my teacher wasn’t a good idea and it certainly was not a priority. But now it wasn’t quite as easy to ignore as I dropped my ass on his lap, feeling his thick cock through his pants even while flaccid. Arousal dripped through me, and I desperately hoped it didn’t soak through my underwear.
Each time I dropped down in his lap I felt him become harder and harder. As my legs began to get sore I moved to stop. I heard his voice, now breathy, “Keep going.” I ignored the sting and kept sinking down.
He began to kiss my shoulders when I hit the lowest part of the squat, each kiss landing on a different place. He released his dick from his shorts and boxers, letting it slide against my ass, making me moan at the felling of it; hot, thick, and heavy. Coach groaned loudly at the friction, his length dragging along the fabric of my boy shorts and leaving a trail of precum behind. His hands rested on my hips, keeping me on his lap.
His fingers edged at the line of my underwear, “Do you want me to fuck you? Sex is a great workout.”
“I’m not sure.” I said, panting. He was still a teacher no matter how attractive he was and I was aware that it was dangerous game even though I wanted nothing more than to play it. His hands moved away as soon as I voiced my doubts.
“If you don’t want to then you don’t have to. Let’s go back to the workout, im sorry for making you uncomfortable.” He said, beginning to redress.
“No!” I shouted, startling us both, “Like you said, it’s a good workout.” I continued sheepishly. He nodded, pulling me in for a deep kiss, lips hot and soft against mine, but gentle.
Coach on pulled away from my lips, pulling a bottle of lube out of his back pocket and spreading the thick substance on his fingers. He pulled my underwear to the side, slipping a finger in my heat. I whimpered, hips moving slightly so it pressed deeper inside. He curled the digit, stroking my walls.
I mewled as he added another finger, pumping it in slowly at first, “Coach!” the pressure of his fingers wasn’t enough.
“Call me Heejun.” He groaned, my moans making his erection twitch against my ass. I squirmed in his lap, pressing harder against his dick in return for the feeling of his fingers pistoning deliciously into me.
My orgasm slowly built up as he stroked the spongy tissue of my G-spot. Heejun’s fingers stroked it, curling into it perfectly. I let out another high pitched whimper before tightening around his digits, cum sliding down them slowly. Heejun tried to gather as much of my essence as possible and spread it so that it coated his hand.
The coach guided me to stand up on shaky legs so he could have better access to himself. He used the cum-covered hand to stroke his cock, making it slick. I stared at it, licking my lips in anticipation for how it would fill me. He gave me an expecting look. Picking up on his hint, I put my hand over his and dragging it down in firm strokes. I squeezed his hand slightly, putting more pressure on his throbbing member.
He soon couldn’t stand it, pulling his hand away. He pulled a condom out of one his pockets, rushing to put it on, “Why do you have lube and condoms in the pockets of your clothes, you’re a teacher.” I chuckled, out of breath from my orgasm.
“A man can dream. Besides it was rather that you liked me or my ass puts you in a trance when I walk by.” He said, smiling beautifully, “Do you want me to do this? Are you sure about this?”
“Yes, im sure.” I confirmed. Heejun pulled my underwear aside, lining his cock with my entrance and slowly pushing into me. I let out a gasp of pain, eyes fluttering shut as the feeling rushed over me, dull ache mixed with sparks of euphoria.
Heejun stroked my hair as we waited, murmuring sweet statements of encouragement. I rocked for a moment, partial savoring the feeling and partially waiting for his instructions, “Are you ready to do more squats, Baby?” I nodded, putting my legs on the ground and doing shallow squats onto his length. My legs wanted to buckle, shaking from the intense pleasure of being stretched perfectly. Heejun was whispering how many squats I did under his breath.
It was erotic, knowing how many times his cock plunged into me. It stirred my arousal further, making me slam down on him.
Pants and moans echoed through the gym, ringing loud through our ears. Heejun pushed my sports bra up so that my boobs were free for him. His thumbs brushed over my hardened nipples, “I’ve been wanting to touch these for a while, constantly teasing me by bouncing up and down during practices.”
He continued to toy with them, more pleasure rushing over me. I was slamming down on him so hard at this point that im sure both of us would be bruised. We didn’t mind at all, pleasure outweighing any other sense. We couldn’t feel pain or think rationally, the only thing we knew is that we both needed more. There was no such thing as too much, both of us wanting to remain attached. I wanted his thick cock to fill me every second of every day. I wanted to taste him on my tongue. Feel him on every inch of my skin, “You’re so hot!” I cried.
My legs gave out a few hundred squats later, falling on his lap but I continued to bounce on him, swiveling my hips so he pressed against all of my sweet spots. He groaned in my ear before grabbing my wrists, pulling them behind my back and slamming into me. The position gave him just the right access when he pushed into me to make me see stars. My body was boiling hot and I was screaming out, “You’re so beautiful. You wrap so perfectly around my cock, taking it like such a good girl.” He praised, thrusts rocking me forward, “Your pretty cunt just wants to cum doesn’t it? To milk me till im dry. You’re squeezing me like you do, Baby.” He hissed, bucking up more and more.
I whimpered in response, becoming increasingly sensitive by the second. Heejun licked the skin of my neck before nibbling on my ear. He moved at the speed of light for a few seconds making me cum, pussy clenching tightly on his cock. Heejun hissed before orgasming as well, his body shaking as streaks of white painted the condom.
“This was definitely one of the most productive training sessions i’ve ever had.” I panted.
“I think you’re right there, and hopefully this won’t be the last, all those squats are going to help your jumps significantly.” Heejun commented, smiling against my neck and laughing.
