---------------------------------------
As the sun rose in the distance, Dawn saw the sign up ahead to the campground.
"We're almost here" She announced in a loud voice, as she looked in the rearview.
Everyone started to stir. Billy's was the first to sit up and look around. As he took a deep stretch he asked. "You drove the whole way, Mom?"
"Yea, I was in the mood for a long drive"
Greg straightened up but didn't address himself right away. He was still scared of what Billy might say.
I'd better play it cool for awhile,
he thought to himself.
Billy looked back at his dad.
"Morning, dad. Did you sleep alright back there? I know how little space there is."
"Umm yea I did son, I can't believe it myself."
"So where are we going to setup camp this year, dad?" Billy asked, as if he's really cared.
"I thought up by the lake, if everyone is up to the hike."
"That sounds great!" Steff spoke while she stretched.
"We'll be able to go swimming," Steff expressed with glee.
Dawn looked back in the rearview mirror at her husband. In a huffy voice replied,
"I wish I knew this back at the house. I would have packed my bikini."
Greg thought and came up with a plan. "Well when we get to the campground, Billy and I could stay there, while you and Steff head up the road to town and find a new bikini there."
"Clothes shopping. This trip is starting off fantastic already, " Steff replied excitedly.
"I guess we could do that. You two wouldn't mind waiting around for us at the campground?"
"No. I think I and dad will be able to find something to do while you to shop" Billy replied, knowing full well that his dad would want to try and talk his way out of what he did with sis.
"Okay then, I'll try and hurry to find a suit."
"Hey mom I think I need a new one also." Steff interjected.
"Steff ,we don't have time for you to try on every bikini in the store"
"Aw ,come on, mom. I'm not that bad, and besides, I would only be waiting around for you to find something."
"We'll see, but no promises"
Shortly after they had left, Billy felt a strange tingle through his body again, and his dick started to increase in size.
"Oh no, not again!" he thought to himself.
Billy's mind started to drift, and his vision went back to seeing his mother bent down on her knees in front of him. He imagined her opening her mouth and taking his dick in it and slowly sucking him off. Then his mind changed people, and now he saw his sister, and she was slamming her ass against their father's dick, screaming out loudly in ecstasy as he was pulling her into him with both hands on her waist, ramming his cock deep inside of her. Again, his mind wandered. He could still see his sister face, as she screamed in her climatic state, but now the man fucking her brains out wasn't her father anymore, it was he.
Billy could feel his cock at full hardness, almost poking out of the top of his jeans. Overnight it must have grown another 2 inches.
Lost in the enjoyment of the new thoughts traveling through his mind, Billy tried to overcome them and bring himself back to reality, shaking the incestual images that were haunting him.
Billy shamefully asked himself, "Why am I thinking these thoughts? Am I really a pervert?
But the urges that were running throughout his body were too much for him to control. The desire that had built up in him of wanting and needing his mother to suck him off, and now fuck his own sister, were almost more than he could stand.
"Okay then I'll just have to live with that fact that I'm a sick, twisted pervert who wants to fuck his own family. So I might as well be the best pervert I can be," Billy thought. And with that, the shame he felt started to dissipate.
Knowing that his dad would want to discuss what he seen last night, Billy was going crazy trying to cover every excuse his dad could use as to why he was lapping his own daughter to a climax.
Somehow he might be able to use it to his advantage, without his father knowing what his true intentions were.
Billy made his way to a grassy area, still trying to stretch the stiffness out of his body.
Looking over at his son, Greg signaled to Billy with his hand. "Billy, we need to talk."
"About what, dad?" He replied, with a faked puzzled look. Billy headed over to his dad.
"I think you know."
"Are you talking about what I saw you and sis doing in the back seat?"
"Umm yea. I need to explain." Billy cut him off before Greg could finish.
"If you're worried that I'm going to tell mom what I saw you can put your mind at easy. First off, I think sis somehow tricked you and secondly, I don't want to see you and mom split up over this.
"That's exactly what happened!" Greg said, breathing a sigh of relief.
"Well I figured as much, dad, but sis must be up to something, and I wouldn't put it past her to open her big mouth and tell mom what you two did. Now that they've gone shopping, she's got all the time in the world to tell mom her side of the story. I would bet it makes you out to be the person who made the advances. Mom isn't going to ever believe you now if you told her what happened. She would want to know why you didn't stop sis, or tell her first thing this morning what Steff tried to make you do."
Greg dropped his head down.
"I think your right, son. I think I'm still in deep shit."
"Not if we put our heads together dad, and somehow make it out that you're not the bad guy here, but the person that was being taken advantage of."
"What do you mean son?"
Seeing the intense interest in his father's eyes, Billy put his mischievous plan into action.
"Well, what would happen if I was able to seduce mom? Then she'd see how it could've happened to you."
Quickly standing tall and crossing his arms, Greg looked sternly at Billy and said,
"What are you saying Billy? I should condone to letting you fuck your mother?"
"No. No. I meant just a little seduction. Not screwing her, "Billy replied with a quick chuckle.
"I mean, god dad, she's mom. How sick would that be?"
Billy realized that is was just as sick as his father licking his own daughter.
"Errr, sorry dad; you know what I mean."
"Yeah I know what you're talking about."
Billy continued explaining his plan to his father.
"If I can get mom just interested in the idea, and not actually doing anything with her, then maybe she could see how it could happen, and that would give you a good opportunity to tell her what happened to you with sis."
Greg paused for a moment, looked up at the morning sky, and then back at his son.
"It sounds just crazy enough to work, but I don't see your mother getting sexually aroused by her own son."
"I could, when we get up at camp, maybe pay mom more attention. You know, compliment her on how pretty she looks, and help her with things around camp."
