[A new collaboration with the popular group HGT Lab has been decided!] This is the first live-action work by Maria Nagai, an exclusive member of NIKUYOKU! Two male students who stopped by a supermarket are stopped by a female clerk outside the store on suspicion of shoplifting. In order to prove their innocence, the two accept their luggage being searched... but it's a trap. Matsunaga Ai is a virgin lover at heart, and has had her eye on the two for some time. Unaware that they are being targeted by a drooling female leopard, the two lose their commuter passes and later go to a housing complex in the suburbs. An afternoon tea party begins in a room in the housing complex with no nameplate... the two are transfixed by Ai, who is dressed in a sexy outfit, a stark contrast to her work clothes. One early summer evening, in a room in the housing complex, a black-haired woman's first time is about to begin! Collaboration with a popular doujin work! Based on the original doujin work "Black-haired Woman's First Time Click here for "I'll let you cum inside me in my secret room"!
