Chapter 3- Tension Rises

The second session came faster than I expected. Marcus texted the night before to confirm, and I found myself checking the clock every ten minutes that morning. Ryan had already left for work, which made things feel a little lighter. No eyes judging every move.

Marcus showed up right on time, wearing a fitted gray shirt that showed off his arms. He smiled briefly as I let him in. “Ready to push a bit harder today, Bella?”

I nodded, already feeling nervous in my workout clothes. “I think so.”

We moved the furniture again and started with a longer warm-up. Jumping jacks, then high knees. My body protested, but his voice kept me going. “That’s it. Nice and controlled. You’re getting the rhythm.”

Things got tougher after that. He had me doing squats again, but this time with a resistance band around my thighs. “Step out against the band,” he said. “Feel it in your glutes.”

I lowered down, thighs burning right away. Marcus stepped close behind me. His hands settled on my hips, steady and firm. “Keep your knees tracking over your toes. Push back like you’re sitting into it. Good. You’ve got strong hips here.”

His fingers pressed into the soft flesh at my sides, guiding me up and down. Not rough, but sure. I could feel the heat from his palms through my leggings. Sweat started beading on my neck. Each time I came up, his grip adjusted slightly, thumbs brushing near the top of my ass. My face heated up for reasons that had nothing to do with the exercise.

“You’re built for this,” he said quietly. “Those curves give you power. Use them.”

No one had ever called my body powerful before. Not like that. Ryan only ever pointed out what was wrong. I pushed harder, breathing faster. When I finished the set, my legs shook.

Marcus handed me water. “You’re stronger than you give yourself credit for. Most women your size quit before they even feel the burn.”

We moved to lunges next. Walking ones across the room. He spotted me from the side, one hand on my waist to keep me balanced, the other lightly touching my outer thigh when I wobbled. “Drive through the front heel. Chest up. There you go.”

His touch lingered a second longer on my thigh. Warm fingers against the fabric. I felt a rush between my legs, a slick warmth that made me embarrassed. God, not now. I was sweating enough already. What if he noticed? I focused on the floor, trying to ignore how sensitive my skin felt wherever he touched.

By the end of the session I was drenched. Shirt clinging to my back and belly, face red. Marcus wiped his own forehead and nodded. “Solid work, Bella. You’re progressing fast.”

“Thanks,” I mumbled, grabbing my towel. My heart was still racing when he left.

That evening Ryan came home and looked me over. “You’re actually sweating this time. Good. Better be dropping pounds soon or this is pointless.”

I just nodded and went to shower. Under the water, I kept thinking about Marcus’s hands on my hips. The way his deep voice said I was strong. It felt dangerous, but I couldn’t stop replaying it.

The third session was two days later. Marcus suggested we try his studio instead of the house. “More equipment, better for progression,” he said. Ryan agreed over the phone. “Just make sure she works hard.”

I drove over feeling a mix of nerves and something else I didn’t want to name. The studio was clean and private, with mirrors on one wall and mats everywhere. No Ryan watching this time.

Marcus started us with deadlifts using light dumbbells. “Hinge at the hips,” he instructed, demonstrating. His own form looked perfect, muscles working under his shirt.

I tried. My back rounded a little.

He moved behind me immediately. Both hands on my waist, pulling me into position. “Like this. Flat back. Feel the stretch in your hamstrings.” His fingers spread wide, holding me steady as I lowered. On the way up, one hand slid to my lower back. “Squeeze your glutes at the top. You’ve got plenty there to work with. It’s an asset, not a problem.”

His voice was low, right by my ear. Complimenting my ass like it was something good. I felt that familiar ache between my thighs again, growing wetter with every correction. My leggings were damp from sweat, but this was different. Slick. Embarrassing. I prayed he couldn’t tell.

We did several sets. Each time he touched me more. Hands on my hips to guide the movement, palms sliding down to my thighs when I needed to widen my stance. “Powerful legs,” he murmured during one rep. “Use that strength. Don’t fight your body, work with it.”

I was breathing hard, face flushed in the mirror. Every spot where his skin met mine felt electric. When he knelt to adjust my foot placement, his hand brushed the inside of my thigh. I nearly gasped. Heat flooded me. I was soaked now, and not just from the workout. My nipples had tightened under my sports bra. This was wrong. He was married. I was married. But my body didn’t care.

“You’re glowing,” he said with a small smile after the set. “Real effort today. I like that.”

We finished with some core work on the mat. Planks, then Russian twists. He held my feet for the twists, knees bent. His thumbs pressed into my calves, then higher when I shifted. “Keep twisting. Good rotation. Your core is waking up under there.”

By the end, I was lying on the mat catching my breath, chest heaving, sweat everywhere. My leggings felt uncomfortably damp between my legs. I crossed my arms over my chest, hoping nothing showed.

Marcus offered a hand to help me up. I took it. His grip was strong and warm. “You’re doing amazing, Bella. Most clients your size fight their curves. You? You’re starting to own them.”

I mumbled a thank you and headed to the bathroom to change. In the mirror, my cheeks were bright red, hair messy and damp. I felt guilty as hell, but also alive. Turned on in a way Ryan had never managed lately.

That night at home, Ryan actually noticed. “You smell like sweat. Finally pushing yourself, huh? Keep it up. I want to see a smaller waist soon.”

“Yeah,” I said. “I’m trying.”

He went to bed early. I lay beside him in the dark, staring at the ceiling. Ryan’s breathing was steady, almost snoring. But my mind wasn’t on him. It kept drifting back to the studio. Marcus’s hands on my waist, firm and sure. The way his fingers dug into my hips during the lifts. His deep voice calling my curves powerful. My thighs.

I pressed my legs together under the sheets, feeling that lingering wetness. Shame mixed with heat. What was wrong with me? Ryan was my husband. But when was the last time he touched me like that? Never with encouragement. Never with heat.

I turned on my side, away from Ryan. In my head, I replayed Marcus correcting my form, his body close behind mine. The compliments. The strength in his grip. My hand slipped under the blanket without thinking. I bit my lip to stay quiet.

This was just the workouts, I told myself. Nothing more. But even as I thought it, I knew the tension was building. And part of me couldn’t wait for the next session.
