Chapter 5: Pool Day – Wet T-Shirt Hell

Sunlight already baked the bedroom walls when I woke, the faint slick residue of massage oil still coating the creases of my palms like a guilty reminder. I could smell her on my skin—warm, herbal, mixed with the faint cherry sweetness that clung to everything she touched. The image of her almost-bare breasts from yesterday refused to fade: those glistening swells spilling over the edges of the sports bra, nipples inches from my thumbs, her hips rocking up against my trapped length while she whispered how good my hands felt. My cock stirred against the sheet, heavy and insistent, before I even swung my legs out of bed. Guilt knotted low in my gut, the same sharp twist that had hit me after every tease so far, but it only sharpened the ache.

Downstairs, her humming drifted up the stairs—light, playful, the same tune she’d used while sorting laundry the day before. A new scent cut through the air: coconut and something chemical-sweet, drifting in from the open window. Sunscreen. The day outside was already brutal, humid heat pressing against the glass like it wanted in. I pulled on swim trunks and a plain t-shirt, trying to ignore the way my pulse quickened at the thought of her in anything resembling a swimsuit. Two days of this and I was already unraveling.

In the kitchen she stood at the counter finishing her coffee, wearing a short silk robe that barely skimmed the tops of her thighs. The belt was knotted loose, the fabric gaping at the neck and riding high enough to show the smooth underside of one ass cheek. She turned at the sound of my footsteps, that warm, flirty smile blooming across her lips like we were just any aunt and nephew starting the day.

“There’s my favorite nephew!” Her voice wrapped around the words with easy affection. “I thought we could spend the whole day by the pool since it’s so hot. I already put towels out there—go get changed and meet me outside.”

She reached up to grab the sunscreen bottle from the cabinet. The robe slipped open just enough. Underneath was the tiniest white bikini I’d ever seen: two small triangles of fabric stretched dangerously tight over her chest, the bottoms nothing more than thin strings that vanished between her cheeks. The top strained against the full weight of her breasts, the material already slightly sheer from the kitchen warmth. She caught me staring and let out a soft giggle, eyes sparkling.

“Eyes up here, sweetie ... or are you excited to see your aunt in her new bikini?” She pressed the sunscreen bottle into my hands, her fingers lingering against mine, warm and deliberate. “You’re going to help me put this on, right? I can never reach everywhere.”
