[Re-collaboration with popular group HGT Lab decided!] This is the first live-action work by NIKUYOKU exclusive Maria Nagai! Two male students who stopped by a supermarket were stopped by a female clerk outside the store on suspicion of shoplifting. The two accepted the baggage inspection to prove their innocence... but it was a trap. Ai Matsunaga is a virgin lover at heart, and had been keeping her eye on the two for some time. Unaware that they were being targeted by a drooling female leopard, the two lost their commuter passes and went to a suburban housing complex later. An afternoon tea party begins in a room in the housing complex without a nameplate... The two are captivated by Ai, who is dressed in a sexy outfit, a stark contrast to her work clothes. One early summer evening, a black-haired woman's first time is about to begin in a room in the housing complex!
