Standalone hentai novel, not based on the manga
The summer heat clung to the suburban house like a second skin, the air thick with humidity and unspoken secrets. My name’s Kaito, an eighteen-year-old slacker home from college, stuck in the monotony of my childhood bedroom. Life was dull—until I stumbled upon something that shattered my world and set my blood on fire.
It started innocently enough. I was sneaking around the house late at night, restless and bored, when I noticed a faint glow spilling from beneath my mom’s bedroom door. Mom—Aiko—was 38, a stunner with long black hair, curves that could stop traffic, and a demure smile that hid a spark I’d never quite understood. She’d been acting strange lately: secretive phone calls, late-night outings, a flush in her cheeks that didn’t match her usual routine of PTA meetings and yoga classes. Curiosity got the better of me, and I crept closer, heart pounding.
The door was cracked just enough for me to peer inside. What I saw made my jaw drop and my body burn with a mix of shock and something darker. Mom was on her bed, legs spread wide, her silk robe hiked up to her hips. Her fingers danced furiously between her thighs, her breaths coming in sharp, desperate gasps. But it wasn’t just that—she was staring at her phone, propped up on a pillow, displaying a video call with him.
I didn’t know his name then, but his voice was deep, commanding, dripping with lust. “That’s it, Aiko,” he growled through the speakers. “Show me how much you need it. Let go.” Her response was a moan so raw it sent shivers down my spine. Her face contorted into something I’d only seen in the wildest corners of the internet—an ahegao expression, eyes rolling back, tongue lolling out, utterly lost in ecstasy. My prim-and-proper mom, the woman who baked cookies for the neighborhood, was unraveling in a way that made my head spin.
I should’ve walked away. I should’ve been disgusted. But I stayed, glued to the spot, my own body betraying me as I watched her arch and writhe, her moans growing louder, more unhinged. The man on the call laughed darkly. “You’re mine tonight, aren’t you?” he said. “Say it.”
“I’m yours,” she gasped, her voice trembling with submission. “Please… don’t stop.”
That was the first night I saw her like that, but it wasn’t the last. Over the next few weeks, I became obsessed, a voyeur in my own home. I’d wait until Dad was asleep or working late, then creep to her door, watching her surrender to her secret lover. Sometimes she’d use toys—vibrators, plugs, things I didn’t even know she owned—pushing herself to the edge while he coached her through it. Other times, she’d dress up: lacy lingerie, thigh-high stockings, even a schoolgirl outfit once, giggling like a teenager as she teased him. Her ahegao face became my fixation, that raw, shameless expression burning into my mind.
Then came the night everything changed. I was in my usual spot, heart racing, when I heard a car pull into the driveway. Dad was out of town, so who the hell was it? I ducked into the shadows as the front door opened, and in walked him. Tall, muscular, with a cocky grin and eyes that screamed trouble. He didn’t even hesitate—just strode upstairs like he owned the place. I followed, silent, my pulse hammering.
By the time I reached Mom’s door, they were already tangled together. He had her pinned against the wall, her robe torn open, his hands roaming her body like he was claiming every inch. “You’ve been such a good girl for me, Aiko,” he murmured, his lips brushing her neck. She whimpered, her legs trembling as he lifted her, carrying her to the bed.
What followed was a blur of heat and madness. He was rough, relentless, stripping her down and bending her over, her cries echoing through the house. She begged for more, her voice breaking as he took her in ways I’d never imagined. Her ahegao face returned, more intense than ever—eyes glazed, mouth open, drool slipping down her chin as she lost herself completely. He spanked her, pulled her hair, whispered filthy things that made her scream. The bed creaked under their frenzy, and I stood there, frozen, my own body screaming with a need I couldn’t name.
At one point, he flipped her onto her back, spreading her wide as he teased her with slow, deliberate thrusts. “Tell me how much you love it,” he demanded.
“I love it!” she sobbed, her nails digging into his back. “I’m yours, Kenji—please, don’t stop!” Kenji. So that was his name. The name burned into me as I watched her unravel, her body shaking through one climax after another, her face a perfect picture of ahegao bliss.
I don’t know how long I stood there, but eventually, they collapsed together, panting, laughing softly as they whispered to each other. I slipped back to my room, my mind a storm of conflicting desires. Part of me hated her for betraying Dad, for hiding this side of herself. But another part—the darker part—wanted to see more, to know more, to feel that kind of raw, unfiltered passion.
The affair didn’t stop. Kenji came over whenever Dad was gone, and I kept watching, my obsession growing. One night, I got careless. I was too close to the door, my breathing too loud, and Mom’s eyes flicked toward the crack. For a split second, our gazes locked. Her face was flushed, her lips parted, still caught in the throes of pleasure—but she saw me. I bolted, expecting her to confront me the next day, to scream or cry or kick me out.
But she didn’t. Instead, the next night, she left her door open wider. She performed for him—and maybe for me—louder, wilder, her ahegao face more exaggerated, like she was daring me to keep watching. Kenji didn’t notice, too caught up in her, but I knew. She was pulling me into her secret, making me complicit.
Things escalated from there. Kenji started bringing props—ropes, blindfolds, even a collar once, which she wore with a wicked smile. They’d roleplay: teacher and student, boss and secretary, strangers meeting in a dark alley. Each time, she’d push further, her cries more desperate, her submission more complete. I started noticing little things during the day—her lingering glances, the way she’d brush against me in the kitchen, her smile sharper, like she was testing me.
One night, Kenji tied her up, her wrists bound above her head, her body glistening with sweat. He teased her mercilessly, edging her until she was sobbing, her ahegao face a masterpiece of torment and ecstasy. “Who do you belong to?” he asked, his voice low.
“You,” she gasped, but her eyes flicked to the door—toward me. My heart stopped. Was she saying it to him… or me?
I couldn’t take it anymore. The next day, when Dad was at work and Kenji wasn’t around, I confronted her. I expected her to deny it, to play innocent. Instead, she stepped closer, her robe slipping off one shoulder, her eyes blazing with something dangerous. “You’ve been watching, haven’t you, Kaito?” she whispered. “Did you like what you saw?”
I froze, my throat dry. She didn’t wait for an answer. She closed the distance between us, her fingers brushing my chest, her voice a sultry purr. “You’re curious, aren’t you? About what it feels like… to let go like that.”
What happened next was a line we couldn’t uncross. She led me to her room, her movements slow, deliberate. There was no Kenji, no phone, just us. She guided me, taught me, pushed me to places I’d only dreamed of. Her ahegao face wasn’t just for him anymore—it was for me, her moans filling the room as we drowned in each other. It was wrong, forbidden, a betrayal of everything—but it was electric, unstoppable.
Kenji still came around, and I still watched sometimes, but now it was different. Mom and I had our own secrets, our own nights when Dad was gone. She’d whisper things to me, filthy promises, her eyes gleaming with that same ahegao madness. I was hooked, lost in her world of passion and deceit.
The summer ended, but the affair didn’t. Mom and Kenji, Mom and me—it’s a tangled web, and I don’t know where it’s going. All I know is that every time I see her face twist into that wild, ahegao expression, I’m reminded of the truth: some secrets are too delicious to let go.
