20-year-old junior college student Akari has a boyfriend but is an adventurous, big-breasted girl with a curious and proactive nature. While working part-time at a café, she's the type to act immediately on her impulses—a modern young woman living her life freely. Recently, she's been growing closer to her boyfriend whom she met through a dating app, forming a happy couple despite already having a partner. Intrigued, she decides to apply as a tester for a newly released lotion. Hesitant at first, she's ultimately drawn in by curiosity and the extra cash, beginning the monitoring session. As she applies the lotion to her arms, décolletage, and underarms, she gasps, "It's cold... so good... I can feel it spreading." Getting into it, she starts responding to even slight stimuli. Lured to a stylish cottage with the promise of higher pay, they mix the lotion with an aphrodisiac—triggering an erotic reaction: "It smells like aromatherapy... but this feels totally different..." Her G-cup breasts spill out of her bikini as they grope her massive tits and stimulate her clit with a huge cock, causing her to blurt out, "I want it...!" Penetrating her soft, juicy pussy bareback, her big breasts bounce wildly during doggy style—her ass quivers, her tits shake uncontrollably. Clinging to a pillar, she screams, "I'm squirting! Squirt! Squirt!" In cowgirl position, the sound of lotion squishing with each thrust fills the room. They French kiss, slippery and wet, as he pounds into her—she cries out, "No, no, I'm coming!" While squeezing her breasts and pinching her nipples, he cums hard inside her with a creampie. Her nipples and tongue are drenched with thick, white lotion from the giant cock. With her pocket full of cash and her body fully satisfied, she completes the monitoring session.
