As many as 8 girls come to my secret base to have sex! A handsome friend will bring you here! From cool girls at school to spear girls from other schools! - Even the girl I admire! It's not just watching! - A handsome man makes me have sex too! The secret base I built on the site of a former factory near my school was intended to be a place of relaxation only for me, but ... It's become a spear room to kill time! It's awesome! I was a virgin, but I became a spear!
