After ten years apart, I reunited with my niece Sana. Her body had matured into a full-grown woman's, yet still retained a childish charm—her casual wear being a loose tank top with a deep, revealing neckline. She wasn't wearing a bra, and her nipples were clearly visible through the thin fabric. She playfully clung to me like she used to, giving me constant accidental flashes of her breasts and panties. Feeling myself getting into dangerous territory, I tried to excuse myself to take a shower, but she followed me into the bathroom saying, "I'll come too! We used to bathe together, remember?" When she asked me to wash her, her soft breasts brushed against my back and arms, sending waves of pleasure I couldn't resist. It was like being in my own private niece brothel. Soon, her hand slowly crept down and reached my crotch, gently grabbing my hardening cock and stroking it. "No, that's not right," I protested weakly. "Huh? But I'm just washing you," she replied innocently, yet with a knowing smirk. "See? You're getting hard again," she teased, clearly enjoying herself. Her soapy handjob brought my cock to full, throbbing erection. Then, with a mischievous grin, she whispered, "Hey, uncle... what do you want me to do with this? You want me to suck it, right?" Before I could answer, she took my thick cock into her small, eager mouth. Her tongue worked skillfully—despite her youthful appearance, it was obvious she'd been with a boyfriend and had plenty of sexual experience. After that, she said, "I'll do other things for you too," and began riding my cock between her soft, jiggling tits. The sensation was so overwhelming that all sense of morality vanished. Then she whispered, "Make me feel good too," flipping our roles. As I sucked and teased her nipples, she moaned softly, "Ah, haa..." Her wet, warm pussy responded eagerly to my fingers and tongue. I slid my rock-hard cock deep into her tight, juicy slit with a wet squelch. After pounding her hard from behind, we moved to the changing room where she mounted me in cowgirl position, riding me with surprisingly fierce energy. Overwhelmed by pleasure, I erupted deep inside her with a massive creampie. As she licked up the spilled cum with her tongue, my cock stiffened again—round two had begun. This time, she straddled me from behind, grinding up and down wildly, squeezing my shaft with her tight pussy. "Uncle... you just came, but you're already hard again," she taunted, her slutty charm pushing me over the edge as I exploded inside her once more. Before I could catch my breath, she asked, "Can you still go?"—already inviting me to round three. Though I thought it might be impossible, my cock refused to soften, so I laid her down and thrust into her from above, finally finishing in the missionary position, emptying every last drop of my cum deep into her beloved niece pussy.
