"Oh! Oh, I'm creaming, Tommy!" she moaned.

Debby's cunt-hole was melting around his fingers. He felt her clit detonate against his thumb and her cunt-lips rippled open even wider. Her cum-cream gushed out in a frothy flood, drenching her pussy and soaking his hand.

"Cum with me! Cum for me!" she wailed.

Her fist slammed down to the hilt of his prick, ad he gasped as his balls exploded. The thick own rushed up his cock and came spurting from his piss hole shooting straight up into the blanket.

"Oooooh!" Debby squealed, thrilled to the core as she watched her brother's jism squirt out dose after dose. Each time she pumped down on his cock, his piss-hole spurted more jism out, and each time she saw another load jet from his cock-head, she creamed on his hand.

Her ass jerked violently as she rippled through her multiple orgasm, spasm after spasm racked her nubile body. The waves came faster and higher, merging into one tidal wave as she reached the very crest. She continued to pump his prick, emptying his balls to the dregs.

Tommy slumped back and Debby squirmed up against him, a dreamy smile lighting her lovely face, her eyelashes fluttering.

"That was lovely," she purred.

Tommy grunted in agreement. Now that his ball were drained, he felt a little ashamed of himself for letting her jerk him off and for finger-fucking her. But not too much. It had only been a mutual hand-job, he reasoned. It wasn't like they had really committed incest.

Unlike her brother, saucy little Debby felt no remorse whatsoever.

"Can we do it again, sometime?" she asked. Tommy didn't reply. He knew that, no matter what he thought now, he would be unable to resist the temptation as soon as his balls were full again. As long as they restricted their activities to hand-jobs, he guessed it wasn't really so naughty.
