Greg turned off the exit ramp and searched for a parking spot. The rest area that he found was quite dark and there were not many cars. He pulled the van up to the closet spot he could find and parked.
Greg turned the engine off and gave a refreshing stretch, as the long drive had taken its toll on him and he couldn't wait to relieve that build up of piss he had been holding in for such a long time. Greg opened the door and hopped out. Lifting one leg and then the other, Greg tried to shake off the stiffness. He turned and glanced at the rear of the van and caught his wife and son watching him.
"I'll be right back," he said.
"I'll come with you, daddy" Steff said, in the middle of a stretch herself.
"We'll wait here until you two get back," Dawn exclaimed. "I need a private moment to talk to Billy about something."
Billy swallowed hard and thought to himself,
I'm in deep shit now. I don't think Mom's too happy with me. I'd better come up with something quick.
Greg gave his wife a quick nod and made his way to the restrooms with his daughter.
Dawn watched as her husband and daughter disappeared. She tried to figure out how to talk to her son about what they did. And as she thought about it, she remembered the dream she'd had and what the dream was about.
Both of them were in the restroom they'd stopped at earlier as she checked out her son's bite. She was on her knees just inches away from his massive hard-on, but in her dream she felt herself getting excited over the sight of that monster dick so close to her. Her son's massive cock was jutting out and looked like it was just begging to be touched. Dawn found herself fighting with the morals of right and wrong, but felt she was losing the battle. Her tingling pussy moistened with the sexual tension that had built up within her. Dawn tried her best to overcome her sinful desires but watched as her right hand reached out slowly and touched her son's manhood. Her whole body shivered. Dawn grasped her son's throbbing love pole between her hands and slowly stroked him. She watched as she jerked his monster dick up and down and pre-cum started to ooze out of his piss hole. She wet her lips as she watched the cum dribble down his massive shaft. As her body leaned forward, Dawn told herself, "No! You shouldn't do this. He's your son!" But her body wouldn't listen to her, and she kept moving closer and closer. She watched as her mouth opened and slowly eased her son into her mouth. Knowing what she was doing was wrong made no difference to how much she was enjoying the way his massive cock felt as it filled up her entire mouth as she tried to take him down her throat.
Dawn bobbed her head up and down and heard her son moan her name, telling her how great she made him feel.
Dawn began to feel her own juices flow out of her excited pussy. She needed to get off, herself. She dropped her right hand down to her twat, and started playing with herself, bringing herself towards her own climax.
Dawn looked up at her son. He took both his hands and pulled her up to face him. Still stroking his pussy spreader, Billy said to her, "Let's cum together, Mom. I want to make you cum." He lowered his own right hand down to his mother's willing pussy, and began to rub her clit with two fingers, building her up to her orgasm. Dawn placed her head on his shoulders, and stroked his thick cock in sync with his own busy fingers.
Dawn moaned, "Oh Billy."
Dawn felt him rub her faster and harder on her now swollen clit. She could feel her excitement building, she knew in any second she'd orgasm, and that was when she awoke.
Dawn came back to the present and turned to face her son, and with a stern look on her face she began to speak, but before she could get a word out,
Billy said "Mom, I'm really sorry for what I did. I don't know what happened. It's like it was someone else controlling my body. It was making me do things I wouldn't normally have done, and I swear my penis was never this big until after I got bitten. I think that bite did something to me. It's made me do things. I think I might be changing into someone else."
"Well maybe there is some truth to what you're saying. But Billy, we can never do that again. Do you understand how wrong that was?"
Billy's eyes began to tear up.
"Yes Mom, I hope you will forgive me. This is the worst day of my life."
"Well maybe we should just cancel this trip and have a doctor take a look at you."
"Mom, please don't do that! Dad would never forgive me if this trip gets ruined on my account."
"There'll be more trips. Your wellbeing is my first concern."
"Just give me a day or two, Mom."
Then, with his head down, Billy said," If it helps at all, what you did to me before seemed to help."
"In what way?"
"Errr. It's hard to explain Mom, but that feeling of someone else controlling me disappeared."
"So you don't feel like that anymore?"
"Not right now I don't, Mom."
Dawn paused for a moment and thought about what her son had told her. She felt sympathy for him. She took his hand in hers and said, "Okay we'll keep this to ourselves. No sense in getting your father upset over this."
"Thanks Mom, and again please believe me how sorry I am. I love you Mom. "
"I love you too, Billy." Dawn slid over to her son and gave him a soft motherly kiss on his forehead.
She backed away and looked out the van's window.
"I wonder what's taking your father and Steff so long."
Greg did take awhile in the restroom. He hadn't realized how tired he really was from all the driving he had done. He threw some water on his face and began to make his way back to the van. Steff was standing outside the doorway to the ladies' restroom.
"I didn't want to walk back by myself so I waited for you, Daddy."
Greg smiled and opened the exit door for her.
"Ladies first."
Steff looked in her daddy's eyes. "Thank you, Daddy."
