Detective Mio begins a stakeout with her junior partner to catch the mastermind behind an illegal trading ring. Trapped in a room with a broken air conditioner, the sweltering heat slowly pushes Mio's desires to the brink. As her senses blur, she touches herself, drenched in sweat. In that overheated state, she takes his cock deep into her mouth with wet, slurping sounds before they engage in sweaty creampie sex. Blaming the oppressive heat for their actions, they give in to their raw lust. Though their relationship was meant to end once the case is solved, Mio finds herself genuinely aroused—this intense emotion becoming something entirely new to her.
