"Felix! Sonia! Dinner time"

"We're having sex mom!" shouted Sonia.

Felix mumbled an affirmation, muffled by the scruff of his sister's neck which he was nibbling on.

Sonia arched her back up higher to meet Felix's thrusts. Her brother's barbs scritched the inside of her vagina, eliciting a small yowl.

Encouraged, Felix picked up the pace. Sonia let out a long yowl at the pleasurable stinging as Felix's barbs raked back and forth along her vaginal walls, scratching the itch deep inside her.

The pace quickened further, and soon with a last loud yowl they were done. Sonia rolled over, toppling her brother off her back. She twisted and writhed against the floor for several seconds, like a stoner who's suddenly become very aware of how soft the carpet is. When her euphoria finally subsided, she stretched herself all the way out, and then curled up with one leg extended to tidy up her cum soaked privates with her tongue.

Felix, similarly, had licked all the residual goo off of his penis and was now grooming the fur on his sheath and balls. When he was finished he scooched behind his sister and began affectionately grooming the fur on the top and back of his twin's head while fondling her lower two rows of breasts.

After they were done grooming themselves, the twins got up and ran downstairs, leaving their clothes behind; Sonia's vagina and eight breasts weren't anything that everybody hadn't already seen every time she went into heat, nor were Felix's genitals not out every time one of the household's females was in season.

"You owe me at least a dozen more after dinner Felix" said Sonia as they ran down the stairs

"As if I'd leave you hanging at just a dozen"

Around the dinner table sat the twins' mother Jocasta, their half-brother Leo, and their half-sister Arlene. On the table was their mother's tuna casserole, as well as four live plucked pigeons.

"All right! Live food" said Felix, running to the table.

Sonia took her time on the other hand, stopping to rub her self against Leo and tell him "You should join us after dinner"

She reached down, unzipped Leo's pants, and deftly slid his sheath down from his penis with one finger. Then she bent down and quickly sucked him off

"I hope you have some toms coming over who aren't related" said Jocasta, "you shouldn't have sex with just your brothers"
