Misty's icy breath fogs the air as she teases her brother, slowly unzipping her parka to reveal her heaving, lace-covered chest. His eyes widen, taking in her perky nipples straining against the fabric, and his cock tents his pants. She straddles him, grinding her pussy against his hardness, their winter clothes rustling like a symphony of their taboo lust. He kisses her neck, his hands roaming her body, cupping her breasts, squeezing her ass. She gasps, arching into his touch, her pussy dripping with arousal. As they stumble towards the bed, they leave a trail of discarded winter gear, their bodies already entwined, ready to combust in a blizzard of passion.
