The air conditioning on a packed bus in the hot summer heat broke, and the inside of the bus was covered in sweat. The blouse of the woman next to me, who seemed to be a married woman, was soaked with sweat and her underwear was completely visible. Our sweaty bodies touched each other, and the wife became excited as her erect penis pressed against her ass and crotch, and she instinctively grabbed it. Unable to calm down, we touched each other in the bus, pulled down her panties, and inserted it while standing, becoming even more sweaty.
