Curious Stepsister's First-Time Bedroom Lesson

The front door had barely clicked shut behind their parents—off to a two-week Hawaiian honeymoon—when Maddie appeared in Jake’s doorway for the third time that hour. She wore an oversized T-shirt that said “Future MILF” in glittery letters and a pair of mismatched socks, one striped, one polka-dot. Her chestnut hair was piled on top of her head in a messy bun that was already sliding sideways.

“So, like… when a guy gets hard,” she began without preamble, leaning against the doorframe, “does it just, boom, rocket straight up like a flagpole? Or is there, like, a warm-up lap first?”

Jake, who had been trying to finish a level of Elden Ring, dropped his controller into his lap. “Maddie. We talked about this. Personal space. Boundaries. The whole ‘I’m your stepbrother, not Google’ thing.”

She batted her lashes—actually batted them, like a cartoon character—and stepped inside anyway. “But you’re a guy. A real, live, experienced guy. Mom and Carl have been married for eight months and I still don’t know anything. I’m nineteen, Jake. Nineteen! I’m basically a fossil.”

“You’re not a fossil. You’re a menace.”

She flopped dramatically onto the end of his bed, kicking her legs up so her shirt rode dangerously high on her smooth thighs. “I’m also still a virgin. Like, capital-V, never-even-fingered-myself-properly virgin. I tried once but I kept laughing and then I got embarrassed and gave up. So. Teach me things.”

Jake’s mouth went dry. He had spent the last eight months pretending he didn’t notice how Maddie had filled out—how her hips had curved, how her breasts strained against every shirt she owned, how her laugh made something low in his stomach tighten. He was twenty-one, not a saint.

“Maddie,” he said, voice cracking like a thirteen-year-old’s, “you can’t just ask your stepbrother to teach you how to have sex.”

“Why not? We’re not blood-related. And you’re literally the safest person I know. You already know all my weird habits. Like how I sneeze when I’m horny.”

“You what now?”

She grinned, cheeks pink. “See? You’re learning already.”

Over the next two days she kept coming back, each visit more unhinged than the last. She demonstrated her “kissing technique” on his pillow, making loud cartoon smooching noises while humping it gently. Jake stared at the ceiling and prayed for strength.

Then she sat cross-legged on his floor in tiny sleep shorts and asked, with complete sincerity, “Okay but what does a cock feel like in your hand? Is it squishy like a stress ball or more like one of those rubbery octopus toys?”

He choked on his energy drink.

On the third night she didn’t knock at all. She simply walked in, closed the door, and locked it with a click that sounded like a starter pistol.

“Jake.”

“Maddie, I’m begging you—”
