A young junior idol named Kasane always has a bright smile on her face, making my old man heart race. Unknowingly gazing at her budding breasts ignites a desire within me to claim them as mine. At our first private photo shoot, she was clueless about what was happening. So, I started touching her nipples, saying they were just doing something everyone else does. As things escalated, we entered full-on breast development training mode. This innocent girl dreaming of becoming an idol was forced to learn how to cum from nipple stimulation. *Note that the recorded contents may vary depending on the distribution method.
