The air conditioner broke and my house turned into a sauna! My sister-in-law is trying to beat the heat with a fan. But that weak little fan doesn't stop the sweat at all, so she's lifting her skirt in front of it, and even though she's not wearing a bra, she's flapping her clothes around, so her huge breasts are visible! I can't help but get an erection, and she notices... Shit! Before I know it, my sister-in-law reaches out for my erect penis! In the end, I give in to the mood of the moment and have sex with her, sweating profusely!
