My niece, whom I hadn't seen in 10 years, had grown into a plump, voluptuous woman... I decided to let her stay at my place when she came to Tokyo for her university entrance exams. Riho, still as gentle and innocent as ever, clung to her uncle, unconsciously pressing her grown-up body against him. Still a child at heart, she even joined me in the bath! With her fully grown body before me, I found myself in a state of near-over-selfie in our mixed-sex bath, playing at the edge of my self-control... Her soft, plump breasts and squishy pussy. I slipped in raw! Her wet hair and wet, see-through uniform were so erotic that I lost control of the sex and came inside her multiple times... (sweat)
