Entering the virtual world of 3DXChat, a brother and sister find themselves in an online sex game gone wild. They log in as their animated avatars, him a rugged, tattooed stud, her a petite, curvy vixen. In the role of strangers, they meet in a virtual bar, their eyes meeting across the room. The chemistry is undeniable. She sips her virtual drink, her avatar's legs crossing and uncrossing, giving him a peek of her lacy panties. He approaches, his avatar's cock already tenting his pants. They dance, their bodies grinding against each other, their avatars' moans filling the virtual room. They find a private room, their avatars' bodies merging into a blur of animated fucking, their online sex game turning into a very real, very intense encounter.
