Detective Haru is on a stakeout with her junior partner, trapped in a confined room as they work to capture the mastermind behind a drug trafficking ring. Stuck in a sweltering room without air conditioning during the peak of summer, deprived of proper sleep and forced into days of abstinence, the tension between them finally reaches its breaking point. Unable to hold back any longer, the two give in to their pent-up desires, passionately licking each other's sweat-drenched bodies. Haru uses her large breasts to tease and stimulate him, then devours his sticky, overheated cock with wet, eager licks. Once ignited, their passion cannot be contained—bodies slick with sweat and fluids, they instinctively crave and take each other. Though they knew this affair would end once the case was solved, Haru finds herself unable to forget the intense, deeply felt pleasure she experienced during their creampie-filled encounter.
