20-year-old Yoshika. An amateur girl with a boyfriend, working as a sales clerk at a body care products shop. She applied through an AV production company's website, seeking her first experience and taking on the challenge. Meeting in a park, she opens up about her life, gradually growing tense as a handsome AV actor arrives. The encounter begins with a kiss, a warm and gentle approach. While still dressed, her F-cup breasts are fondled, their nipples exposed and soft, captivating him completely. She's brought to wetness through cunnilingus, fingering, and vibrator play. During a blowjob, her boyfriend calls—she continues both the handjob and blowjob mid-call, heightening the taboo thrill and intensifying the erotic atmosphere. Penetration begins in missionary while still clothed, starting slow then building in speed, her moans growing ragged and real. Oil is applied, clothes come off, and she reaches her first climax in a side position with one leg raised, then in grinding cowgirl. Craving more pleasure, Yoshika herself removes the condom, switching to bareback. In rear-mounted cowgirl and standing doggy, she's pounded hard and fast, crying out as creampie juices spill out, receiving two creampie loads. "Sorry, boyfriend," she whispers—but he seems to enjoy it too. Even after filming ends, they're shown having sex again in the shower, capturing a vibe that feels just like real romance.
