---------------------------------------
As I awoke the next morning, my mind traveled back to the previous night, and all that had unfolded. I couldn't help but wonder how Sis was going to react after she caught mom and I, and what would she do now that she knew all that had transpired in her absence. However, I also was interested in Dad and how he set me and mom up from the beginning. I was determined to set my full concentration on figuring out what my father's hidden agenda might be.
Was it because Sis wouldn't approve of mom and me, and that perchance she would feel some sympathy for him by seeing us together? Or was it possibly to get Sis used to the idea of having sex with another family member?
I thought long and hard on the subject, but in the mist of all my thinking, my psyche got stuck on seeing Dad and Sis together again. And as before I pictured them both entangled in each other's arms. I watched as Sis slowly worked her hand inside Dad's pants and freed his hardened dick and said "I'm here for you, Daddy. Princess is going to make it all better." Her fingers tickled his balls and made him grunt in joy.
As their forbidden romp unfolded in my mind, I found my own hand inching closer to my stiffening pole. I closed my eyes and decided to just enjoy my imaginary journey into this twisted fantasy that was exciting me so much.
My hand stroked on my dick as Sis eased herself close to Dad's throbbing penis and slipped it deep inside her mouth.
"Ohh... Fuck," I said out loud as the image brought me closer to my own release. My hand went faster as I watched Sis increase her bobbing on Dad's cock, his noisy grunts echoing in my mind.
But I quickly stopped as I felt the touch of a strange hand grasp around my excited dick and snap me out of my perverted fantasy.
"Rebecca!"
"Shhh... you'll wake everyone," she said as her fingers lightly stroked up and down my shaft.
"Ohh... Ohh... shit," I whimpered as her face inched closer to my protruding tool.
"I've thought about your cock all night," she said as her sweet wet lips kissed and slipped over my stiff pole.
I closed my eyes and relished the feeling she was sending throughout my entire body, as her tempo increased along with my pleasure. I opened my eyes and watched intently as she skillfully sucked away on me, and I thought about how much she resembled my Sis.
It didn't take long before my imagination ran wild and I pictured Sis slurping hungrily on my meat, and my cock stiffened more as my deranged thoughts pushed me over the edge.
I became so excited by my fantasy my hand quickly gripped tightly to my imaginary lover's bobbing head and pushed her down harder on me as my hips thrust up sending my entire cock down her silky throat.
"Oh... Fuck... Sis!!!" I moaned before I realized what I'd said.
Rebecca quickly stopped upon hearing my ploy and slipped her mouth away.
"Sis?" Rebecca questioned as our eyes met.
I didn't know how to respond. Nevertheless, before I could think of some bullshit excuse Rebecca moved closer to my ear and as her hand lightly stroked on my pole, she whispered "You want to fuck your sister also don't you?"
I felt my dick jump and expel some precum as her taunting words sent new erotic pleasures though my body.
"Oh... Such a naught boy, Mike. First your mom and now your sister."
"No... I... I... Oh shit!!!" I said as her hand tightened around my stiff shaft and brought me closer to coming.
"Shhh... It's okay... just close your eyes and picture her stroking you."
I did just that, and felt my nutsack boil its hot seed to its pending release.
"I bet she would be a hot fuck, Mike. Having her sweet little pussy trying to take all of your cock inside her would be a dream come true, wouldn't it?"
I couldn't hold back any more as my ass bucked off the bed. "Oh fuck... I'm going to cum," I exclaimed and Rebecca quickly sucked my cock back in her mouth, just as I exploded.
I felt my entire shaft slip down her throat as my dick pumped and spurted its juices.
"Oh Rebecca... You're so fucking good at this," I said as I spewed the last of my seed inside her mouth.
I watched as she slowly eased my dick out and licked her lips.
"Mmm, Mike, your Sister doesn't know what she's missing, but maybe we can change that."
"What are you saying?"
"Maybe I can nudge her into actually wanting you."
I felt my dick again begin to harden.
"Would you be willing to fuck your Sister, Mike?"
"I... I'm not sure," I said, but in fact, the thought did get me quite excited.
Rebecca looked down at my penis as it slowly grew in size again.
"I think you can do it, Mike. I see your dick is warming up to the idea of sliding inside her."
It was true. My wicked thoughts had betrayed what little morals I had left. I indeed wanted to fuck my own Sister.
"Okay I would like it, but I don't think Sis would ever go for it. I heard how disgusted she sounded after hearing Dad wanted to fuck her."
"I didn't say it wouldn't take some effort to sway her, Mike. I said I might be able to get her interested. The rest would be up to you."
Just then it hit me. Another plan was building in my brain. If Dad truly did all this for a crack at Sis, what would he do if he saw me fucking her? Now I needed for this to happen.
"Rebecca I think I have an idea on how to get back at my father also," I said as I explained to her what I had in mind.
After I laid out the quick details on my new endeavor, Rebecca agreed and headed for the door.
"I think it might work, Mike," she said and quietly slipped out.
I jumped out of bed and dressed before I headed downstairs. I had a couple of things I needed to do before I could put my new plan into action. First thing was to pay my friend Donny a visit. I knew he had to be in on what Dad had planned from the beginning. If it wasn't for the DVD he gave me, I wouldn't have ever believed in Dad's after-work escapades. But before I rushed out I caught Sis standing in the archway to the kitchen with a blank expression on her face.
I tried to speak but abruptly Sis protested before a word could be said.
"How could you, Mike?! With our mother, who willingly fucked you? "It just happened. Well, sort of. However, I'm not sorry it did. If fact, I've never been so happy. I'm sorry if it offends you Sis, but the truth of the matter is I've always wanted mom."
"So that makes it okay? Because you always wanted mom?"
"I'm not going to debate if it's okay or not. I already know how mom and I feel. If you can't be happy for us, maybe living with Dad is the right choice for you. But I know they already told you how Dad wants your sweet little ass for himself, and conned me into making a move on mom without me realizing it. I would bet he's sitting around right now just waiting for you to show up. It shouldn't take him long before your little pussy is sliding up and down his dick and you're begging for more."
Sis slapped me hard on the cheek, but as I saw another smack coming I quickly grabbed her wrist before her hand could connect with my skin.
"Let go of me!"
I eased my grip and apologized for the lewd remarks I'd made. I quickly left and returned with the laptop mom used to film Dad. I set it on the kitchen table and found the movie mom had shown me.
"Watch this and then decided what to think about everything," I said as I walked away and headed out the door. However, again I was distracted. A man in a suit approached me as I walked towards my car.
"Excuse me are you the son of Howard Wilkes?
"Yes, that's my Dad. Why are you asking?"
"My name is Mr. Harold, and I'm an insurance agent. Is your mom at home? I need to ask her some questions concerning your Dad."
"My Dad doesn't live here anymore, and my mother is still sleeping."
"Hmmm... Well do you know a Miss Cabbit, by chance?"
"No... I've never heard of her."
"Well... Miss Cabbit tried to take out a large insurance policy on your father, and to tell you the truth this isn't the first time we've seen her name attached to a policy. She's collected on two others. We've suspected foul play in the previous policies but could never prove it." He said.
His talking had piqued my interest. I wasn't sure if it was Sandy, he was referring to, but I started to put it together.
"You wouldn't happen to have a picture of Miss Cabbit, would you?"
Mr. Harold opened a file and handed me a photo. Sure enough it was her. The picture looked like it had been taken a good distance away and without her knowledge.
"We had her under surveillance, and then she vanished, until now."
I lied and said. "Well, I haven't seen her, but if you give me your business card, I'll contact you if I do."
Mr. Harold gave me his card and thanked me for my time. Things were starting to look up as I expanded my plan to also include my Dad's black widow mistress.
As I arrived at the motel, I had worked out all the details and was sure this time Dad wouldn't be aware of my ploy.
