During a scorching summer vacation, I stayed with relatives while my aunt Nao helped me with my homework. She was my mother's younger sister—smarter than Mom, stunningly beautiful, and so relaxed around me that I could not stop staring at her loose neckline. One day, while we were studying alone, she pressed her sweat-glistened breasts against my body, flashed a seductive smile, and took the lead. Her relentless hip movements brought her adult nephew role-play partner to a creampie without him thrusting even once.
