A fucked-up experiment

You see Sandy, you don't understand what I'm asking... because you rarely understand anything anyway, because you are mentally challenged. You are retarded, plain and simple. You do not know how to read or write, you barely speak at all because it is too complicated for your very limited mind." Sandy's eyes immediately lost their gloss, her mouth opened slightly and then saliva began to drool over her neck and breasts. This time, not even a nagging feeling invaded John's mind. This change was instantaneous and for everyone, Sandy has always been the sexy but retarded redhead friend of Amy.

" Do you understand what I'm trying to explain to you Sandy?" John said. "Gaaaaah!!!! Me no no"With that her instinct take over and she began to ride John' dick while making incoherent strange sounds, like a baby praticing how to speak: "dah dah doh ta, ma ma me...". John was slightly annoyed that the retard friend of Amy was delaying his test so he asked his mother's help. Soon, Sandy had a large cucumber in her ass while John was pounding her pussy. Soon, he came in her, then push her away when she failed to understand that it was over. She began to cry, but then she became fascinated by the feeling of the cucumber in her ass so she began to pull it in and out, laughing everytime she did (her memory had become so bad that she was surprised every time by the cucumber leaving then reentering her gaping asshole).

So John approached Brian and Sophia, who were still going at it doggy style but were visibly close to finish. He brushed Sophia's ass with his hand and then absently remarked: "you sure are fucking her nicely Brian, I'm almost jealous of your technique, it's as if you 2 were made for each others 'cause you're fucking like 2 horny dogs" . John then put his hand firmly on Sophia's ass and was about to say something to try to alter Brian sexuality and behavior (he never liked the guy so why not make him a wimpy faggot) but suddenly he got a strong sense of uneasiness watching these 2 fucking, as if it was wrong that they were humans, that it would make so much more sense it they were dogs, because they were fucking exactly like it but this thought did not made sense to John, they were clearly human beings, not dogs. So with a bit of thinking, John touched Sophia on the head and said: "you 2 are fucking like dogs because you behave like dogs, and because you behave like dogs everybody thinks you are dogs, including yourselves".

John got a puzzling look on his face. What was he doing talking aloud to Amy's dogs? "Too much sex is making me loosing my mind he laughs, thinking". Just as he was asking her sister why she wanted to go to the beach with her retarded friend and her 2 dogs, Sophia was howling loudly as Brian her dog mate was filling her up. Then Brian dismounted her bitch, got around the table sniffing the floor, and getting his leg up, he began to piss all over the table's leg.

"Shit Amy!" Get you stupid dogs outside before they ruin my house! Quick!"
"I'm sorry master." With that, the 3 of them got outside. (John land is big). Soon, both Brian and Sophia were walking (always on all four) in small circles , searching for the perfect spot. "Hurry up for Christ's sakes" Amy asked of her dogs. Then , finally, they got their perfect spot and soon, both were taking a shit. Then, they both got to sniff it a bit and then, satisfied, they came back towards the house, Sophia stopping midway to piss on a tree. "These dogs were not easy to trained but I like them anyway because they are my dogs, even if they are not very bright nor athletic for dogs", Amy thought, while scratching Brian behind the ear and telling Sophia she was a "good girl".
