As the two men shot off into her body, tilling her ass and her mouth with cum, Tanya could hardly take the pleasure. She flailed around on the bed, her movements like a jackhammer, as thunderous pangs of orgasm swept through her body. She gagged out a moan, gurgling on Brian's cum, as the enormous rush of pleasure Gary was giving her, stormed through her guts like a jolt of lightning. She humped her body back and forth, her ass slapping against Gary, maintaining a constant level of pleasure, while she gobbled down Brian's last few wads of cum.

While Brian and Gary lay on the bed, totally spent, Tanya lay on her side. She scooped out the cum in her asshole and lapped it down, sucking on her fingertips.

"Ummmmmmmmmm!" she moaned, rolling the mixture of Gary's and Brian's cum around on her tongue, "this is the best part!"

She flexed her ass muscles, forcing out the last gobs of Gary's creamy jism and ran her fingers around in her pussy, soaking up her hand with the mixture, and then rubbed the liquid around on her tits. She massaged and slicked up her tits and then sucked on them, taking the pussy juice and cum into her mouth, letting it slide gently down her throat.

"Now I know why you fuck your sister!" Brian said to Gary, watching Tanya eat there cum.

Tanya looked at them both with a twinkle in her eye.

"I'm almost finished with this," she said, licking up the last few slippery drops of jism. "Anybody care to give me some more?"

"We'll give you all you want, and then some, won't we?" Brian said to Gary.

Gary didn't say anything – he just pulled his sister down on his cock and kept his part of the bargain, while Brian watched, and then kept his part.

CHAPTER FOUR

Between school and Brenda, Brian found it easy to avoid being alone with his sister. He still couldn't bring himself even to consider making it with her, although she certainly kept the idea very much alive in both their minds with her lewd remarks and open invitations.
