Two bi sisters, bored and curious, find themselves alone with a strapping, horny man. They exchange glances, a silent agreement passing between them. One sister, the braver of the two, initiates the fun by unzipping his pants, revealing a massive, throbbing cock. She takes it in her mouth, savoring the taste and texture, while her sister watches, eager for her turn. They take turns sucking him, their lips and tongues exploring every inch, their hands caressing his balls and shaft. The man, enjoying the show, reaches down and fingers their wet pussies, making them moan around his cock.
