All Chapters of My Husband’s Brother, My Filthy Trainer: Chapter 1 - Chapter 10

MIA The private room felt smaller once the door closed behind us. Soft light came from the ceiling panels, and the mirrors on the far wall reflected every movement. I stood near the mat with my arms crossed, trying not to look at myself. Jake walked over to the first machine and rested one hand on the padded seat. “We’ll start simple today,” he said. “Nothing heavy. I just want you to learn the equipment so you feel comfortable next time.” I nodded. My voice still felt stuck somewhere in my throat. He gestured for me to sit. I lowered myself onto the seat, careful not to meet his eyes for too long. Jake crouched beside me and adjusted the pin on the weight stack. “Hands here,” he said, guiding my fingers to the handles. His palms were warm and steady against the back of my hands. “Keep your back straight. Pull the bar toward your chest, then let it go slow. Don’t rush.” I did as he said. The movement felt awkward at first. My arms shook a little even though the weight was light

MIAI got to the gym twenty minutes early on purpose. Ryan had dropped me off again with another short comment about “not wasting Jake’s time,” then driven away. The parking lot was still half empty. I sat in the passenger seat of my own thoughts for a full minute before forcing myself out of the car.Inside, the main floor already had a few regulars. Three women near the squat racks glanced over when the door closed behind me. One of them—tall, dark ponytail, perfect posture—let her eyes travel from my face down to my soft stomach and back up again. She didn’t smile. Neither did the other two. They just turned back to their weights like I wasn’t worth the effort of a second look.My face burned. I kept my head down and walked straight toward the hallway that led to the private room. Jake had given me the code last session so I could wait inside if I arrived first. I punched it in, slipped through the door, and shut it quietly behind me.The room smelled the same—clean mats and faint

MIARyan told me about the dinner only two hours before we had to leave.“It’s important,” he said while buttoning his shirt. “My boss will be there. A few clients too. Just wear something nice and don’t make it weird.”I looked at the black dress hanging in the closet. It was the only thing that still fit without pulling too tight across my stomach. “I don’t feel well tonight.”He glanced at me in the mirror. “You’ll be fine. Just smile and stay quiet if you don’t know what to say.”That was how I ended up in the passenger seat, hands clenched in my lap, while Ryan drove toward the restaurant. The place was upscale—soft lights, white tablecloths, quiet music. When we walked in, several people already stood near the bar.Then I saw her.Lena wore a red dress that hugged every curve and stopped mid-thigh. Her hair fell in loose waves, makeup perfect. She looked like she belonged under these lights. Ryan’s face changed the moment he noticed her. He walked straight over, arms open.“Lena

MIA Jake stood just inside the closed door, eyes moving from my face down to my hands still pressed against the side of my bag. The empty condom wrapper sat hidden in the pocket, sharp against my palm. Neither of us spoke. The air in the private room felt thick enough to choke on. I forced my hands to drop and tried to keep my voice steady. “I’m ready.” He watched me for another second longer than usual. “You sure?” “Yes.” He nodded once, but his eyes stayed on me. “Alright. We’ll start with rows.” I moved to the cable machine because standing still under his gaze felt worse. He stepped behind me the way he always did, hands settling on my waist to check my form. The touch was light, professional, but today it burned. I could still feel the ghost of the foil wrapper in my bag and the way his eyes had lingered on my hands when he first walked in. “Elbows in,” he said quietly. “Pull to your ribs.” I pulled. The weight felt heavier than usual. Every time I completed a rep I waite
