They wake up covered in their saliva

When Justin woke up this morning, he felt that his pillow and blanket were wet for some reason. He then noticed that his cheeks, chin and chest were covered with some liquid as well. That's when he felt the urge to spit ! He got up of bed and ran to his trashcan and spat a huge glob of saliva inside. He could not believe how much there was, almost enough to fill his mouth ! And what was even stranger is that he felt incredibly horny too ! He checked inside his boxers and saw that his penis, which was fully erected, seemed to have grown since last night. How bizarre !

Again, he felt the need to spit again and did so into his trashcan, surprised at how fast his saliva had been produced. He then took a shirt to wipe his face and chest from the saliva and went downstairs to see if his mother could help him with his situation.

Meanwhile, Macey was in the dining room busy trying to call 911, but for some reason she couldn't manage to get anyone to answer her. "What is happening ?" she thought to herself. When she woke up this morning, the entire front of her shirt was soaked with saliva, and she had to spit very oftenly because her mouth was quickly getting filled with that liquid. She got up from her chair and ran to the sink and spat a large glob into it. She couldn't believe how much there was, but strangely enough, seeing all of that spit somehow aroused her a lot.

She heard someone going down the stairs and turned around to see Justin, bare chested and drooling. Upon seeing him, she instinctively began to drool on herself, staining her spare shirt.

"Mom ! What's going on ?!" asked Justin. "I have no idea ! Is your sister okay ?!" said Macey as she ran up to her son. She placed her hands on his shoulder and began to feel her pussy moisten all of a sudden, while Justin also felt his dick harden from the contact. They couldn't figure out why they found each other so attractive all of a sudden. That's when Abby, Justin's sister, appeared on top of the stairs.

"Mom ! I think I'm sick !" she said, accidentally spitting out some spittles at her mother and brother. Instead of being disgusted, they found this rather arousing, although they had no idea why. Abby ran down the stairs and looked at Justin and Macey, visibly confused. Her white shirt was soaked with saliva, and her hardening nipples were clearly visible through it.

They all looked at each other with uncertain expressions. They then realized that they desperately wanted to fuck together : Justin wanted to suck hard on his mom's tits, Macey wished to tonguefuck her own daughter while Abby craved to **** on her brother's enormous cock. Why was this happening ? They couldn't tell, but now they no longer cared. Even though they were family, they couldn't resist any longer.
