"Oh please, I already know for a fact that you look at pictures of the 2 of us when you masturbate. So me seeing you naked isn't anything new for you Lia." Nonchalantly replied Jess, playfully flicking one of Juliana's nipples.
Turning extremely red with embarrassment, Juliana quickly began studdering out her denial "R-r-right, b-b-because I'm some kind of pervert who gets off to pictures of herself and her sister in string bikinis."
"I never said what we were wearing" smerked Jess.
"Shit. Uhhh, I can, uhhh. Damn it..." finally accepted Juliana, who had just revealed one of her secrets by accident. "Are you mad?"
"No, which even I feel is kind of odd. I actually didn't expect you to admit to doing it since I said it as a joke. But when you did, for some reason, I felt flattered. Like, it is something I should be furiously angry or completely disturbed and disgusted with. But instead, for some reason it made me really happy. It was as if I was good enough to be with you." Admitted Jess bashfully, which lasted about a whole 3 seconds before her naturally perverted personality returned in full force. It was a side effect of her permanently wet pussy. "Please do not misunderstand, I really don't want to like, ligitimently go out with you or anything. You ARE my sister after all. But, I wouldn't mind it if we sometimes helped eachother masturbate, or something. And speaking of which... hehe"
Juliana just watched as Jess bent down and grabbed the open end of the hose, which was still secured deep inside of Juliana's ass. With a mischievous grin, she pushed the end up her own pussy, which in tern began piping her own pussy juice into her sister's ass. Realizing what was about to happen as she watched Jess go from just slightly aroused into full blown heat. Her liquid was quickly filling up Juliana's intestins. And while the feeling was very comfortable, possibly even pleasurable, she wasn't quite sure she wanted to be her sisters cum dump quite yet.
However, before she could pull the hose out of her sister, she turned back into a fountain in order to releave the excess. If it was just water, or a small amount, she would never choose to become a fountain. But the quantity and speed this time was too much for her human body to safely handle. "Ha! Mhmmm! haha, fuck. Maybe I took it a bit too far this time. I can't even get up anymore. Ughhhh! Damn it." Struggled Jess, having fallen down onto her hands and knees from putting herself into a spontaneous heat. She was now too sensitive and horny to get up. Luckily, she had a contingency plan in case this ever happened to her when she was alone. However, she really wished Juliana wouldn't see what she had to do next to free them both.
"Sam! Come!" She shouted. A few seconds later, their male german shepherd dog bounded into the back yard. "Come here boy. I need your help, again."
Jess had actually fucked her dog numerous times when she was home alone. Their parent were surprised at how Sam always obayed Jess, reguardless of what was going on. She had also seemed to somehow know exactly what he was thinking too sometimes. Juliana just watched, frozen in a quite erotic position. She was on her back, with both legs fully behind her, and was using her hands to spread her pussy wide open. Her tits were pushed slightly together by her arms, while both her nipples each shot out a steady arc of pussy juice, which landed into her own gaping pussy, which was pooling and overflowing. Her face was contorted into one of those "ahegao" faces, with her eyes rolled back and her tongue sticking out. She made this face because she felt it would be really fitting for her current perdiciment. And also because just like her apparent bestiality loving sister, she was also a huge perv.
"Sam. Fuck your horny bitch!" commanded Jess. No sooner then she said that, did max jump on her, ramming his dick up her ass. Her pussy was not currently an option with the hose still in it, but she didnt care. She had done anal many times with Sam, and was by now always lose enough for him to painlessly and quite easily slip his big cock into her ass.
While panting heavily, just like the bitch in heat she was, Jess was really enjoying the fuck. It was now at a point where she would habitually begin acting like a dog for sam. She had found that doing this made him fuck her way better. She began barking like a dog, in time with his heavy thrusts. Until he finally started to cum inside her. At which she completely became a stupid mess from the pleasure. Smiling like an idiot laying her head dow on its side in her own pool of drool with out carring. This sudden release freed her up just enough to where she was able to quickly pull out the hose.
2 minutes later, Juliana reverted back into her human form, although now with a pussy and womb full of her sister's fresh cum. Not that she especially minded, being careful to not spill any of it, while also attempting to not let Jess realize her what she was doing. "I know what you are doing Lia, so don't riskndropping any of it by trying to hide it from me. I am in no position to tell you what is and isn't an acceptable fetish. If you want to have my cum baby, go ahead."
"You good?" Asked Juliana, concerned for her sister's well being since she wasn't moving much.
"Yeah, my ass is just knotted with Sam's cock still inside at the moment, so I can't move from this spot for about 30 minutes." You can just leave me here if you want to do something else, Lia. The warm sun feels nice, so I may fall asleep."
After hearing that, Juliana made her way over and got a closer look at Jess's ass, where indeed there was still a thick dog cock burried inside of it. She gave her sister's ass a playfull poke with one of her long fingers, and giggled while laying down next to her to join her brief nap.
