My younger brother, who went to a university in the city, decided to live with his sister who had moved to Tokyo. However, his sister was an outrageous playgirl, and on weekends, she would make a big fuss with her playgirl friends, talking about lewd topics! When the brother, who was pulled into this circle, got discovered to be a virgin... they started a so-called "Sex Education Session," initiating his deflowering experience! He didn't want to lose his precious first time like this! But he couldn't stop the piston due to the exhilarating feeling of his first time having sex! In the end, he was begged for his penis by all the playgirls all night long, ejaculating repeatedly!
