This is a sad and erotic video that was left on the iPhone of a college student in love. I will tell you a part of it. Although Mariko, an office lady, and the college student who lives in the room next door have feelings for each other, they have not confessed their feelings. However, both of them are at a good age. The college student looks at and touches Mariko's breasts in her room, and even caresses her over her underwear. However, one day, a relative who came to Tokyo appears in Mariko's room, and she starts acting strangely. "Is there something strange?" the college student asks timidly, but Mariko answers evasively. The college student visits her room with a new manga that Mariko wanted to read, saying, "Let's get back together! But the relative appears in a T-shirt and pants, says, "I like this manga too," and takes the manga and disappears into the back of the room. After that, the college student goes to return the Tupperware he borrowed, but he hears a strange voice coming from Mariko's room, and she herself is sexy and close to the relative. He asks, "Did something happen?" but Mariko replies, "Nothing." The college student, curious, uses a selfie stick to secretly film the room from the balcony, and sees Mariko and a male relative having sex. Mariko is thrust hard in the missionary position, stretching out with an ecstatic look on her face. The college student is shocked by the sight of her completely fallen female self, muttering, "Oh no, Mariko...", but he makes up his mind and goes around to the front door and tries to break in. Then... what? The front door is open... [This is a compilation of previously unreleased footage added to the Amateur floor number.]
