All Chapters of My Stepbrother's Lesson : Chapter 41 - Chapter 50

Chapter 42(The Professor’s Pet – Chapter 7)Sofia didn’t bother with underwear anymore.She arrived at 5:58 p.m., skirt soft against her bare thighs, the memory of his cum still vivid enough that she had woken up aching that morning. When she locked the office door behind her, Dr. Crowe was already waiting.He stood beside the desk with his sleeves rolled up and his expression unreadable. The surface had been cleared completely. The lamp was angled to cast light directly across the wood.“Come here.”She walked to him. He took her bag and set it aside, then gripped her waist and lifted her onto the edge of the desk in one smooth motion. The wood was cool against the backs of her thighs. He stepped between her knees and pushed them open.“Lie back.”Sofia leaned back until her shoulders met the desk. The position left her exposed, skirt bunched around her waist, nothing underneath. Dr. Crowe’s eyes moved over her slowly—her flushed face, the rise and fall of her chest, the wetness alr

Chapter 44(Brother’s Best Friend – Chapter 1: The Crack)The house was quiet in the way it only got after 2 a.m.Lila sat on the kitchen counter in an old T-shirt and sleep shorts, bare legs dangling, nursing the last of a glass of water she didn’t really want. Upstairs, her brother Nate was dead asleep—passed out after too many drinks with the only person he ever let stay over this late.Jake Morrow.Her brother’s best friend since forever. Twenty-six. Tall, broad-shouldered, all sharp edges and quiet intensity. The same Jake she had been stupidly, secretly in love with since she was sixteen. The same Jake who still ruffled her hair like she was a kid and called her “kiddo” even though she was twenty now.He walked into the kitchen like he owned it, wearing gray sweatpants and nothing else. His dark hair was messy. There was a faint flush still on his neck from drinking. He stopped when he saw her.“You’re still up.”“Couldn’t sleep,” Lila said. Her voice came out softer than she wa

Chapter 46 (Brother’s Best Friend – Chapter 3: The Second Time)Lila was still awake when the door to her bedroom opened at 1:47 a.m.She didn’t need to look to know it was him. The house had a particular kind of silence when Nate was deeply asleep, and Jake moved through it like someone who already hated himself for being there.He shut the door quietly and locked it.For a moment he just stood there, back against the wood, staring at her in the dark. Moonlight cut across the bed through the half-open blinds. Lila was on her side, wearing the same oversized T-shirt she always slept in. She sat up slowly.“You said it wouldn’t happen again,” she whispered.Jake’s voice came out rough. “I know what I said.”He crossed the room like the decision had already been made hours ago. When he reached the bed he didn’t kiss her right away. He grabbed the hem of her T-shirt and pulled it over her head in one motion, leaving her bare. His eyes dragged over her body with something close to anger.

Chapter 48(Brother’s Best Friend – Chapter 5: Guilt & Filth)Nate left for a late shift at 7:40 p.m.The second the front door shut, Jake was already coming up the stairs. He didn’t knock. He barely closed Lila’s bedroom door before he had her pinned against the wall, mouth on hers, hand shoved roughly between her legs.There was no warm-up this time.He kissed her like he hated her for it. Like he hated himself more. When he pulled back, his eyes were dark and angry and hungry all at once.“I shouldn’t be here,” he muttered against her mouth, two fingers already pushing inside her. She was soaked—she’d been wet since the moment Nate said he was leaving. “I keep telling myself I’ll stop. Then I think about how tight you were last night with my hand over your mouth and I get so hard it pisses me off.”Lila moaned as his fingers curled. “Then why—”“Because I’m a piece of shit.” He pulled his fingers out, spun her around, and bent her over the desk hard enough that the edge bit into he

Chapter 50(Brother’s Best Friend – Chapter 7: Emotional Shift) It started with something small.Jake was in the kitchen when Lila came downstairs the next morning, hair still damp from the shower. Nate had already left for work. The house was quiet. For a second it felt normal—until Jake looked at her and his expression did something complicated before he locked it down.He didn’t touch her.That was the first sign.Usually he couldn’t keep his hands to himself once they were alone. Today he poured coffee, leaned against the counter, and kept a careful three feet of space between them like distance might undo the last week.“We should cool it for a few days,” he said without preamble. His voice was flat. Controlled. “Nate’s starting to look at me weird. And this…” He gestured vaguely between them. “It’s getting messy.”Lila’s stomach dropped. “Messy how?”Jake’s jaw tightened. “You know how. Don’t make me say it.”She knew exactly what he meant. The way she looked at him now. The w
