It is August, the temperature is brutal, and an exhausted repairman arrives for his final air-conditioner job of the day. His client is an elegant, slightly mysterious married woman whose unit has stopped working. He falls from the stepladder while inspecting it and lands on top of her, accidentally kissing her. The mix of sweaty lips, saliva, and her sensual scent leaves him dizzy—then she pulls him in for another kiss. She strips off his clothes, licks the warm sweat from his body, and alternates between a provocative smile and a hungry stare. With the room at 38°C and hot as a sauna, their sweaty encounter turns into filthy, reckless cheating sex.
