His Dark Fantasies
How could a girl be jealous of her sister?
It was even more exciting to think that they'd have the kind of sexy, open marriage their parents had. It felt right that they'd follow in their parents' footsteps. As she sucked her brother's cock, she felt her sister's hand moving in synch with her lips as they went up and down that hot, delicious man cock.
"That's it, sis," Tara said. "Suck our husband's cock, but don't forget to save some for his other wife."
The middle sister then felt Tara's hand on top of her head, following her bobbing motion up and down. Nothing had ever felt so right, and she knew it always would.
