Chapter 5: The First Time

Marcus pushed forward, and I felt the thick head of his cock slide into me. Slow at first, stretching me open. I gasped, gripping the edge of the workout bench tighter. God, he was big. Bigger than Ryan had ever felt, even in the early days.

“Fuck, Bella,” he groaned behind me, voice rough and low. “You’re so wet. So tight around me.”

He sank deeper in one smooth thrust, filling me completely. My mouth fell open. A loud moan escaped before I could stop it. Sweat dripped from my forehead onto the bench. My heavy breasts swayed under me as he started moving, hips slapping against my ass with every stroke.

“You feel that?” he said, one hand gripping my hip hard while the other tangled in my damp hair. He pulled my head back slightly. “This pussy is gripping me like it’s been waiting for a real man.”

I couldn’t answer with words. Just shaky breaths and whimpers as he fucked me harder. The sound of skin on skin filled the living room. Rough. Wet. My juices coated him, making every thrust smoother and louder. He dominated me completely, body pressed over mine, muscles flexing against my back.

“Yes… Marcus,” I managed. “Oh god.”

He reached around and grabbed one of my breasts, squeezing it roughly, pinching the nipple. “These curves drive me crazy. Your thick ass bouncing on my cock. You’re so fucking sexy, Bella. Don’t ever let anyone tell you different.”

His words hit deep. Ryan hadn’t called me sexy in over a year. He made me feel gross, unwanted. Marcus made me feel like a woman again. Desired and Powerful. Every thrust pushed that feeling deeper into me.

He pulled out suddenly, spun me around, and lifted me onto the bench like I weighed nothing. My back hit the padding. He spread my legs wide, stepped between them, and drove back inside me in one hard motion. I cried out, nails digging into his shoulders.

“Look at me,” he ordered, that deep dominant voice sending shivers through my body.

I met his eyes. Intense. Hungry. He fucked me steady and deep, grinding against my clit with every push. Sweat poured off both of us, making our skin slick. My thighs jiggled with the force, but he didn’t care. He loved it. His hands roamed everywhere, squeezing my belly, gripping my thick thighs, pulling me onto him harder.

“You’re mine right now,” he growled.

“I’m yours,” I whispered, voice breaking as pleasure built fast. “Fuck… I’m yours, Marcus.”

He smiled darkly and picked up speed. The bench creaked under us. I wrapped my legs around his waist, heels digging into his back. He leaned down, sucking on my neck, then my breasts, biting just enough to make me moan louder. One hand slipped between us, rubbing my clit in tight circles.

“Come for me,” he demanded. “Let me feel this pussy squeeze my cock.”

I shattered. The orgasm hit hard, waves crashing through me. My whole body shook. I screamed his name, back arching, pussy pulsing around him. He didn’t stop. Just kept thrusting through it, drawing it out until I saw stars.

“Good girl,” he praised, slowing for a moment so I could catch my breath. “But we’re not done.”

He pulled out again, flipped me onto my hands and knees on the mat. From behind once more, he slammed back in. Deeper this time. Rougher. His balls slapped against me. One hand spanked my ass, the sharp sting mixing with pleasure.

“Throw it back on me,” he said. “Show me how bad you want it.”

I pushed back, meeting his thrusts. Sweat flew with every movement. My heavy tits swung, nipples hard. He reached forward and grabbed them, using them as handles to pull me onto his cock. The dirty talk kept coming.

“Ryan doesn’t fuck you like this, does he? Doesn’t make this fat pussy drip the way I do.”

“No,” I admitted, voice hoarse. “Never like this.”

“Louder.”

“He doesn’t! God, Marcus… harder!”

He gave me what I asked for. Pounding me fast, skin slapping loud. Another orgasm built quick. I was in shock at what we were doing, his wife, my husband, right here in my house, but I couldn’t stop. I craved more because I haven't had sex in a long time. I needed him deeper.

He sensed it. Pulled me up so my back pressed against his chest. One arm wrapped around my waist, the other hand on my throat, not squeezing hard but holding me in place. Standing now, he fucked up into me while I bounced on his cock. My feet barely touched the ground. Complete control.

“Come again,” he whispered hot against my ear. “I want to feel it.”

I did. Even harder this time. My legs gave out, but he held me up, fucking me through the spasms. My moans filled the room. Juices ran down my thighs.

Marcus growled and pulled out. He laid me on my back on the mat and climbed between my legs again. This time slower, deeper, eyes locked on mine. Passionate now, not just rough. He kissed me hard, tongues tangled, while his hips rolled against me.

“You’re so beautiful like this,” he said between kisses. “Sweaty, fucked out, taking my cock. I could do this every day.”

I believed him. For the first time in years, I felt sexy. Wanted. My hands explored his back, feeling the muscles flex as he moved inside me.

We stayed like that for a while, bodies slick, breathing together. Then the hunger returned. He hooked my legs over his shoulders and drove deep. The new angle hit everything perfectly. I came a third time, crying out, nails raking down his arms.

“Fuck, Bella… I’m close,” he groaned.

“Come inside me,” I begged, lost in it. “Please.”

He thrust a few more times, then buried himself deep. I felt him pulse, filling me with hot spurts. He groaned loud, body tensing over mine. We stayed locked together, panting, sweat mixing between us.

For a moment, everything was quiet except our breathing. I was in shock. I just cheated on Ryan. With my trainer. In our house. But my body hummed with pleasure. I already wanted more. Craved his hands on me again.

Marcus kissed me softly this time, then pulled back with a smirk. “We’re not stopping here.”

He was still hard inside me. We started moving again, slower but building back up. I wrapped my arms around his neck, lost in the feeling.

Then I heard it.

The garage door rumbling open.

Ryan’s car.

My eyes went wide. Marcus froze for half a second, still buried deep, cock twitching inside me. We were both breathing hard, bodies slick with sweat and cum, right in the middle of the living room floor.

The car engine cut off.

Footsteps.

We were still hooked together, hearts pounding, when the door from the garage clicked…
