By the time Bob had opened his eyes and noticed what was going on, he was too far gone to care. And anyway his moral position was not very good, as here he was fucking his own thirteen year old virginal sister-in-law. He couldn't very well protest, then, at her sucking on a dog's penis. So he merely closed his eyes again and continued fucking.
Rhonda stripped off her clothes and then sat down naked on the carpet, lighting a cigarette as she watched her gorgeous blonde sister being fucked by both the neighbor's German Shepherd and by her fiancee. It probably wouldn't be a bad idea to get some pictures of this, but that could wait until later.
In the meantime she would just sit there, finishing her cigarette and rubbing her fingers into the slippery wet folds of her pussy. She would want to have Cesar's long beautiful penis ramming up inside her rectum next while she sucked on her husband's penis, and wouldn't that be a surprise to Bob! She had always been such a prude in sexual matters – until this beautiful dog liberated her body and soul.
But then they were in the future now, a bright new future. Cesar, that wonderful neighborhood pest, had come to change their lives. She would love him for all eternity, and Bob as well. Maybe Sharon could come and live with them once they were married. And Cesar? What about Cesar? Rhonda couldn't bring herself to think about that unhappiness now…
Eventually tiring of her cigarette and the grim thought of losing the animal back to her neighbor, the tall redhead stubbed out the butt and sauntered over to her fiancee. Gripping his perspiration soaked curls, she twisted his head around to bring his nose and mouth directly in contact with her hotly squirming pussy.
Bob got the idea immediately, his tongue shooting out to penetrate the trickling wet folds, moving inward swiftly through her hair-lined furrow to lick at her vibrating little clitoris. Rhonda groaned, her head falling back with all of her long red hair falling over her prettily dimpled buttocks. The nearness of her huge hard breasts also acted like a magnet for Cesar's lengthy red tongue, and he began lapping them hungrily in a dual assault of oralism.
By now Bob could feel his orgasm come thundering up from his wildly throbbing testicles. He groaned loudly, shuddered once, and then he was spewing his hot churning sperm upwards into his teenage sister-in-law's ecstatically rippling cuntal passage just as Cesar also began barking and helping, squirting scalding animal seed down Sharon's gluttonously sucking throat.
With cum being poured into her from both ends, the lascivious thirteen year old blonde reached her own orgasm as well, gushing a clear viscious fluid all over her brother-in-law's still pistoning cock as she wailed in rapture, "I'm cumming!"
Her mind spun with ecstasy and she wanted to swoon – but not before her greedy little cunt and mouth had gobbled as much cum into her belly as she could take.
By their side, her gorgeous redheaded sister was also reaching her climax under the mouths and tongues of her fiancee and animal lover. Rhonda groaned and twisted as if trying to get away, then smashed her wildly throbbing pussy over Bob's face like a rubber mask, groaning endlessly as a series of loins-splitting orgasms rent her flesh, one on top of the other, from toe nails to hair ends.
By the time the four of them had stopped shuddering, the two females were lying on their backs on the carpet, holding hands and moaning as only a satisfied woman can moan. Cesar lay down, too.
"What… how?" Bob looked up at Cesar quizzically. Then seeing the smirk on his fiancee's face, he broke out into a grin, too. "Some show, doggie! What do you do for encores?"
"He's our new pet, darling. Borrowed 'til the weekend, but he doesn't live far away," informed Rhonda.
"Christ, if that's what it takes to get you two off, then I'm all for it. If you're going to make it with other males, I guess a dog isn't going to steal your heart away."
"Oh, yeah," giggled Rhonda. "You've got pretty stiff competition there."
"Tell you what. You can have Cesar and I'll take your little sister here. It's best we make those arrangements now before we're married…" Bob looked serious for a moment.
"That's right darling… Oh, so much has happened since you went away. So much has changed. But I have the feeling it's all for the better…"
Bob looked down at Sharon's parted unblemished ass cheeks and moved his rigidly growing cock in between to part them towards her snugly puckered anus. "So do I," he smiled up at his wife-to-be.
