Samantha's POV
Derek's hand was in direct contact with my skin, tracing its way around it like familiar territory. His second hand was still encasing my butt and it left there to join his right hand. But, instead of putting it in my p***y area, he used it to hook the waistband of my shorts, tugging it down.
I jerked back up immediately, grabbing his hand. “The attendant is coming back soon.”
An evil grin tugged at Derek's lips. “No, he isn't. Told him I need some privacy for a while. We have about an hour to ourselves.”
His lips took mine before I could say anything else and his fingers continued tugging my shorts down. Cool air slapped against my p***y and I inhaled sharply as his fingers inched closer to my c**t. Still kissing me, his second hand returned to my ass while his leading hand traced circles around my c**t. I nearly went mad with anticipation as he continued teasing me. He brought his hand close enough to make my breath quicken but far enough to leave me yearning for his touch on my c**t.
Unable to take the torture anymore, I sought out his hand with mine. At that same moment, his fingers glided over my c**t and onto my p***y lips. I bit down on my lips to muffle the moan that erupted from me. A sudden warmth took over my whole body and I shuddered from having his hands massage my p***y lips.
As good as it felt, it wasn't enough. I yearned to have his fingers inside me. I wanted him to tame the hunger that continued traveling round my body, leaving me a desperate mess. To my disappointment, Derek pulled back suddenly. Then I saw his hands going for the edge of his sweatpants and yanking it down his hips. My gaze fell on his tremendously erect c**k as it sprang free like a hungry animal. At that point, my instinct took over. I reached out, wrapping my hand around the enormous member. His breath came out sharp as a result, and the way his eyes dimmed urged me to continue. He let me have my way for a few seconds, enjoying the way I grazed my palm along his length.
“You're so f*****g good with your hands,” he said harshly. Gladdened by the compliment, I flashed him a seductive smile and tightened my grip around his c**k. I only managed to jerk him off for a few fulfilling seconds before he grabbed my waist and spun me around.
The force of the movement made me gasp in shock, but I barely had the time to recover from that before he held one of my thighs and lifted it. The nearest object to me was the treadmill and I grabbed onto it to keep myself steady. Behind me, Derek was parting my p***y with his fingers. My pulse thudded in my ears as I braced myself for what was about to happen.
Even with that, nothing prepared me for the burst of pain and pleasure that traveled my body as his huge c**k eased its way into my p***y.
“Yes, take all of me in,” he urged, pushing himself all the way in.
I felt myself stretching to accommodate him but it still didn't feel enough. Every part of my body felt as if it was on fire. He drove into me in the slowest manner possible, giving me time to adjust to the feeling of having his c**k inside me.
I clamped my eyes shut and whimpered when he suddenly picked up the pace, slamming into me with all the energy he had.
“Oh, God. Derek!” I cried out. My whole body rocked from the suddenness of the movement. Every last bit of control I thought I had was wrenched from me by his throbbing c**k. Pleasure ravaged my body, making my eyes roll in my head as he drove into me continuously.
“You like that?” He asked in a voice that was raw with desire. I opened my mouth to answer but all that came out was a loud moan as he drove into me again. The friction caused by his wide c**k gliding against my p***y walls sent heat to every nerve ending in me.
He was ruthless and his d**k was the one passing the message across. My moans were the most audible thing in the gym, rivaled only by his satisfied grunts. My legs trembled, just like my whole body, but Derek wouldn't stop. He thrust harder at me, seeking to ruin me with his c**k.
The sound of flesh slapping against flesh filled my ears, but it was eclipsed by the moans that rippled up my throat with each thrust from Derek. I felt his hand grabbing my neck, forcing me to remain in place as he thumped me.
“De…rek,” I breathed. The sound came out as a weak plea, a testimony to the unbearable pleasure I felt.
Derek increased the pace of his movements, f*****g me as if that was the sole purpose of his existence. His thrusts were rhythmic and powerful. So powerful that they caused me to shudder all over. Heat started to pool in the pit of my stomach and I felt it coiling like a snake ready to strike. Knowing what it meant, I began moving my hips along with Derek, aiming to match his movements.
Deep down, I was aware of the indecency of what we were doing, but it only made me move faster, chasing my orgasm like a high. Derek seemed to be doing the same thing because he began thrusting into me with renewed urgency. I felt weak in the knees, so much that my legs wobbled. He picked up the pace even further, forcing guttural moans from me.
The heat in my belly started spreading to other parts of my body. As it went, I felt a familiar burning sensation moving along with it. My p***y clenched and unclenched around Derek's c**k, adding to the intense sensations I felt.
With a last few powerful thrusts, Derek sent me over the edge. My orgasm came in an overwhelming rush and I let it consume me. Uncontrollable moans left my lips and my whole body shook violently. At the same time, I heard Derek grunting without stopping. He pulled out of me suddenly and I felt his c*m on my butt, warm and thick. I collapsed against the treadmill afterwards, totally drained and useless.
