A suspicious man invites a group of mommy friends under the guise of a "sex life survey," suddenly asking, "What do you think about big dicks?" While one replies, "Size doesn't matter in sex," is that really true? The man responds, "Want to take a look?" and urges her to grab it. She lets out a shriek—"Kyaa!"—yet instinctively starts licking it. Just then, Haruki receives a phone call and abruptly leaves. The moment they're alone, Maina pounces on the huge cock! This sexy housewife was made for dick! Maina, a beautiful woman with a clean record of infidelity, verbally resists but can't hide her arousal. When asked, "Do you wear underwear like this?" her shaved married woman's pussy is exposed. "Is your husband into shaving it?" he asks, sliding a finger in—her slit already soaked. Though he teases, "You're so nasty, Mrs.," she climaxes anyway. The survey ends here, but then he asks, "What should we do with this?" "Put it inside me," she pleads. "Incredible! So big! It's hitting the deepest part..." as if her true erotic desires are finally voiced. Just approached on the street, yet things spiral into the unexpected. "Since your husband always cums inside you, it's fine to do it inside, right?" Spurt! "Such a huge cock, and so much sperm!" Then asked, "How was it?" she admits, "A big cock feels amazing."
Later, we meet Yuzu, who has sex about twice a week—shy and adorable—and Sayo, who hasn't had sex in two months but is totally into it. Sayo is asked, "After two months, don't you forget your husband's size?" She giggles, "My body remembers!" Yuzu adds, "As long as there's love, size doesn't matter." Invited to touch, a finger plunges deep. "What does a girl's finger smell like after being inside a friend?" "Like a girl," she replies. Then, penetration into the dripping wet Yuzu. "Eh? Wait, it's huge! Like a log!" "Did you cum right in front of your friend?" "Ah, so big... I'm cumming again. I'm gonna come!" "So embarrassing..." "Your wife's tightness made me cum inside." Amid the chaos, creampie. Now it's Sayo's turn. "Do you like being spanked?" "Maybe I do..." SLAP! SLAP! "Ahnn!" Taking the chance, they examine the married woman's anus. "Such a beautiful asshole." Her friend? "Super clean!" she says. Already dripping without any stimulation. "I'm squirting from just fingering!" Fully primed, bareback insertion. "I don't think I've ever taken anything this big before 💛 N-no way, I'm coming!!!" "Did you see? My friend just came on a cock!" Dazed by her first time with a giant dick... "Hey, did you hear? Your friend just came." Sayo, too, gets a creampie! Finally asked, "Based on the results, does penis size matter?" She answers, "...Yes, it does. Laughing."
