"Oh, brother!" she moaned as the cum warmed up her mouth with creamy deliciousness.

She licked his cock, running her tongue up and down the shaft, taking into her mouth all of his spent cum, and swallowing it around in her throat before swallowing it. She released one hand from his cock and scooped up the cum off her face and chin and took it between her lips, moaning as it slicked down her throat.

Gary stepped back and watched as his sister fondled her tits, rubbing his jism round on the soft mounds. And then she bent her head and sucked on her tits, savoring the taste of his cum that had spilled on her hard nipples. And then he looked at Brian.

"What's the matter, Brian?" Gary asked. "You look like you've seen a ghost!"

"She's your sister!" Brian stammered. "How could you do that?"

"Easy!" Gary said, sitting beside his sister. "It's because I love her," he added, placing his mouth on his sister's cum-stained lips. They kissed long and eagerly, not at all like brother and sister and lay back on the bed together, their arms intertwined.

Brian watched as Gary caressed his sister's tits, while their tongues flicked against each other, in a gently dancing motion. Tanya placed her hands between Gary's legs and held his cock and squeezed it gently. As she did so, Brian moved as though in a dream. He reached over and touched Tanya, on the shoulder, letting his fingers play with her soft skin. He ran his hand down her arm and then over to her tits, cupping them tenderly.

Tanya pulled her face away from Gary and looked at Brian. "You want to fuck me now?" she asked.

"Hell yes!" Brian said, his voice eager.

"Then get over here and shove that big dick in my cunt!" she commanded with a smile.
