My hand was already wrapped around my cock when the clock hit midnight, the room thick with the low hum of my laptop fan and the faint, stale musk of my own dried cum from the night before. I’d jerked off twice earlier thinking about her, but it wasn’t enough. It was never enough. The posters on my walls—faded bands from high school, a couple of half-naked models I’d pinned up when I was sixteen—stared down at me like they knew my secret. The glow from the screen painted everything blue, turning my bedroom into this ordinary suburban cave where a twenty-one-year-old guy was supposed to be studying for finals or scrolling TikTok. Instead, I was lost in Rachel Thompson again. Mrs. Thompson. Jake’s mom. The woman I’d been obsessed with for seven straight years.
I stroked slow, teasing myself, letting my thumb glide over the slick head where pre-cum already beaded like dew. My cock pulsed heavy in my fist, thick and aching, veins standing out like they were trying to burst free. God, she was everywhere in my head tonight. I closed my eyes and let the memories flood in, the ones that always made me leak like a faucet.
There was that pool party last summer, Jake’s backyard turned into a suburban oasis under the July sun. Rachel had worn that modest one-piece swimsuit—the black one with the high neck and the little white trim that made her look like the perfect church mom. But when it got wet ... fuck. The fabric clung to her full, natural D-cup breasts like a second skin, the weight of them making the material stretch and outline every curve, her nipples hardening into tight little peaks from the cool water. I’d been pretending to scroll on my phone while she laughed and splashed with the neighbors, but my eyes kept dragging back to the way those heavy tits swayed when she climbed out of the pool, water streaming down her soft tummy, tracing the wide flare of her hips and the thick, creamy thighs that rubbed together just enough to make my mouth water. Her ass—perfect, round, heart-shaped—jiggled with every step across the deck, the suit riding up just a fraction between those cheeks. I’d had to excuse myself to the bathroom and jerk off into a wad of toilet paper, biting my lip so hard I tasted blood, whispering her name like a prayer.
Another memory hit harder. The garden last spring. She’d been out there in those tight black yoga pants, bent over pulling weeds, the fabric stretched so thin across her ass that I could see the faint outline of her panties underneath. The seam disappeared between her thick thighs, riding up with every tug of her arms, her wide hips rocking back and forth in a rhythm that made my cock twitch even now. I’d been helping Jake carry out some patio furniture, but I couldn’t stop staring—the soft curve where her ass met her thighs, the way the pants hugged the plump lips of her pussy from behind. When she straightened up and turned, wiping sweat from her forehead, her tank top had ridden up, flashing a strip of pale, smooth belly and the underside of those breasts. She’d hugged me goodbye after, her vanilla lotion mixing with the warm, sun-baked scent of her skin, pressing those heavy tits against my chest for just a second too long. Her nipples had been hard—I swear to God they’d poked through her thin cardigan like they were begging for attention. I’d gone home and edged for an hour, replaying the way her body felt against mine, the faint trace of her natural musk under the lotion, imagining burying my face between those thighs while she baked cookies downstairs like nothing was wrong.
Seven years of this. Seven years of stealing glances at PTA meetings, at church potlucks, at every casual dinner where she’d smile at me like I was still the awkward kid who used to crash on their couch. She was forty-four, recently divorced, sweet and church-going and always in those modest sundresses or cardigans that hid everything but somehow made it hotter. Full natural D-cups that swayed when she moved, a soft tummy that begged to be gripped, wide hips and thick thighs that could crush a man in the best way, and an ass so round and perfect it made my balls ache just thinking about it. I’d jerked off to her more times than I could count— in my car after helping her move furniture post-divorce, in the shower after pool days, late at night like this, always whispering Rachel ... Mrs. Thompson ... fuck, I need you while my cock throbbed and spurted ropes of cum onto my stomach. She had no idea. None. The perfect mom next door, baking chocolate chip cookies for the neighborhood, quoting Bible verses at book club, while I fantasized about peeling those modest clothes off and claiming every inch of her.
My hand sped up a little, the wet shlick-shlick of pre-cum filling the quiet room. My cock was leaking steadily now, the head shiny and flushed, balls tight and heavy. I edged myself, squeezing at the base to hold back, letting the frustration build like it always did. She’s right down the street right now, probably in bed in one of those thin nightgowns, those big tits rising and falling while she sleeps, completely clueless that her son’s best friend is stroking himself raw over her. The thought made me groan low, hips bucking up into my fist.
I needed something new tonight. Something realer than memories. I’d been scrolling used-panties sites for weeks, obsessed with the idea of sniffing a woman’s actual worn underwear— the real scent of pussy, sweat, and arousal trapped in soft fabric. Not some fake porn prop. Real. Gritty. Anonymous profiles with blurry photos and handwritten notes that made it feel dirty and intimate, like you were stealing a piece of someone’s private life. My laptop was already open to one of the bigger fetish sites, the kind with real seller listings that felt raw and believable. I refreshed the feed lazily with my free hand, the other still working my shaft in long, slow strokes, thumb circling the sensitive underside where it felt like electricity.
And then I froze.
The profile name hit me like a punch to the gut: ChurchMomNextDoor.
The thumbnail was a modest, blurred photo of a woman in a light sundress—the exact kind Rachel wore to PTA meetings and Sunday service, the fabric hugging her wide hips just enough to hint at the thick thighs underneath. My heart slammed against my ribs. No. It couldn’t be. I clicked in, breath catching, and the full listing loaded.
