Chapter 3: Laundry Day Tease

Incest Sex Story: Chapter 3: Laundry Day Tease - Shy 20-year-old Ryan is home alone when his curvaceous 36-year-old step-aunt Tara (38H tits, killer curves) moves in for two weeks. What starts as innocent hugs quickly becomes pure torture: crushing tit-smashes, “accidental” flashes, oil massages, damp panties, and breathy “good boy” whispers. Extreme slow-burn tease and denial for nine chapters explodes into raw, explicit taboo sex—titfucking, creampies, breeding talk, squirting, and more. One long, aching “lesson” he’ll never forget.

Morning light filtered gray through my curtains, but my mind was already wide awake, replaying the kitchen in relentless loops. The way her plush curves had molded to my back when she reached for the sugar, the low breathy sounds she made while my thumbs worked her shoulders, the way that thin shirt had slipped and let me glimpse the soft upper swell of her breast. Her nipple had stood so obviously against the fabric at the end, dark and insistent, right before she brushed against me one last time and left me throbbing in the empty kitchen. I lay there with my heart thudding, cock already half-hard under the sheet from the memory of her bent-over ass in those tiny black panties, the damp spot at the crotch, the way her cheeks had parted just enough to show everything. Guilt twisted low in my stomach—this was my step-aunt, the woman who used to bake cookies for me at family gatherings—but the ache between my legs only grew sharper.

I dragged myself out of bed, pulled on loose basketball shorts and a plain t-shirt, willing my morning stiffness to settle. The house already carried her presence: a faint trace of her skin and perfume drifting down the hallway, mixing with the distant hum of the washing machine from the basement. I told myself I was just going downstairs to help with chores like any decent nephew would. Nothing more.

The laundry room door stood open at the bottom of the basement stairs. I stepped inside and stopped cold.

Tara was at the folding table, sorting through a towering pile of clothes, wearing only a black lace bra and a matching thong. The bra looked at least two sizes too small, the delicate cups straining to contain her full, rounded breasts, pushing them high and tight together until the cleavage was almost obscene. The lace edges bit gently into the soft, pale flesh that spilled over the tops, and her nipples pressed visibly against the thin material, already stiff from the cool basement air. The thong disappeared completely between the smooth curves of her ass, the thin strip of fabric vanishing into the warm cleft. Her long dark hair was twisted up in a messy bun, a few loose strands brushing the back of her neck as she hummed softly to herself, completely at ease.

She heard my footsteps and turned, that warm, familiar smile lighting her face. “Oh, Ryan! Perfect timing. I was just about to call you down. These big loads are too much for me to handle alone.”

Her eyes flicked down to the front of my shorts for the briefest second. My cock jumped hard at the sight of her, thickening instantly against the thin fabric. She noticed—I saw the tiny spark of satisfaction in her gaze—but she kept the smile sweet and auntie-like.

She started handing me pieces to fold. First came her everyday bras, plain and practical, then the sexier ones she had unpacked the first night. The fabric felt warm from her body, the underwire still carrying the faint scent of her skin and perfume, a soft, intimate trace that made my fingers tremble. She held up a lacy red bra right in front of my face, the cups sheer and delicate. “Do you think this one still fits me after all these years? My breasts have always been so full ... sometimes I worry they’re getting too big for the cups.”

While she spoke she pressed the empty bra against her chest, sliding her hands inside the cups and adjusting her own heavy flesh. She lifted and squeezed, letting the soft weight spill deliberately over the lace edges, her nipples stiff and dark against the fabric. The motion made them bounce and settle, the lace stretching taut. My hands shook as I folded the clothes, heat flooding my face. She stepped closer, her bare thigh brushing mine, warm skin on warm skin. “You’re such a good boy helping me like this,” she whispered, voice low and affectionate. “Most nephews would be too embarrassed to touch their aunt’s underwear.”
