Cassie
All characters are 18 years of age and older. If you don't like these type of stories move on.
My sister text me that she was held up at work and would be a lot later than expected. I got this as I pulled up towards her house. Her text also read that she shouldn't be home any sooner than 6 p.m. Cassie would start dinner and that she was sorry but would make it up to me. I smiled at that. My sister or I should say my 'step' sister knew how to make it up.
Our parents had gotten together when we were 11 and 12 years old. We grew up under the same roof, but there was no blood relation. My sister, Constance, or Connie as she went by, got pregnant when she was 18 and about to graduate high school with Cassie. They got married but it didn't last. He bolted and she had to raise Cassie pretty much by herself. I have to give it to her though. She raised Cassie, finished school, got a degree in accounting and had done well for herself.
Meanwhile, after high school I went into the Army during the GWOT with spec ops. Did several tours in the sand box, amongst other activities that won't be discussed. I was in and out of both their lives as my career permitted. Connie was super strict on Cassie, had her going to a private school, tracked her, curfews, etc. She determined that Cassie wasn't going to repeat the mistakes she had made. I was the closest thing to a steady father figure Cassie had and we were very close. Being the 'crazy' uncle as I was introduced as, had thus far kept the boys away....or so I thought. Teens are teens and they always find a way...I certainly did.
Cassie was the identical image of her mom Connie and they were often mistaken for sisters. I think my sister told me they shared clothes now. Both were stunningly beautiful. They shared blonde hair, brown eyes, slim figures, full rack, toned legs, and a great ass. Like her mother, Cassie bloomed early, and won Homecoming Queen, Miss Popularity, etc. Connie kept her on a tight leash but she supported her in athletics, academics and superlative activities she involved herself in. Cassie played soccer, volleyball, brain brawl, and volleyball. Her athleticism kept her busy as well as in shape.
Cassie had recently turned 18 and I helped Connie throw her a birthday party at my house since I had a swimming pool. She had a certain naiveté to her but she wasn't stupid in any regard and she seemed a lot more mature than the boys her age. During the pool party she held the attention of every hetero male there. She also seemed to understand the charm she possessed and kept the boys on edge. She was discovering the sexual power she possessed and it was amusing to watch her flirt and tease these boys. The girls on the other hand were jealous, but not in a malicious way. Just typical teenage shit.
I did notice during the party there was one kid who looked at both Cassie and Connie with that wolf hungry stare. He was an arrogant little shit and talked a good game, but I knew he was full of shit. I watched him follow Cassie around, checking out her body and knew what was on his mind. It was his car parked in the driveway of my sister's house when pulled up.
My sister had a rule that no boys were allowed if someone wasn't home. I walked around the back and let myself in the back door with my key. As I made my way through the kitchen I heard the unmistakable moans of a guy getting pleasure. I crept in unobserved toward the back of the couch where I could see the back of this dudes head.
I got to the point where I could see him sitting, his trousers were undone, his cock was out and Cassie's hand was wrapped around it stroking up and down.
Cassie was on her knees between his legs slowly giving him a jerk. Cassie spit on his head and slowly smeared it with her hand. Cassie was topless. Her shirt and bra were scattered on the floor. She still had her shoes and her skirt on. Her heavy melons swayed and bounced as her arm moved up and down his shaft. His eyes were closed and his head rested on the back of the couch. Honestly, Cassie looked bored but hadn't noticed me standing there.
"Please Cass? Can't you just lick it just once?"
"No! If you don't like what I'm doing you can finish yourself and leave."
I reached into my pocket and pulled out my folding knife. In one motion I flicked open the blade and grabbed the boys hair pulling it back further and laid the flat portion of the blade across his throat.
"Yes, I think it is time you left" I said quietly.
The boys whole body levitated and he gave out a very unmanly shriek. Cassie jumped as well and scooted away from him, covering her tits with her arm.
"Don't move a muscle or I will open your throat." The boy froze, his manhood deflating like a balloon.
I looked at Cassie "Don't you move either little girl...you are in a lot of trouble." Cassie's eyes dropped to the floor and all color drained from her face.
I pulled the boys hair even harder and painfully he scrambled up and over the couch until he was sitting on his knees behind the couch and at my feet. My blade never left its place. I noticed his cell phone was laying on the couch next to where he had been sitting.
"Cassie, get his cell phone." Cassie got up and obeyed my command, trying to keep her tits covered from view. "You can knock off the modesty, I've seen them already. Bring it around here."
Cassie obediently walked around the couch to where I was standing.
"Hold it up Cassie. What's your passcode?"
The boy spouted off his passcode and Cassie punched it in. Sure enough, just as I suspected he had taken pictures of Cassie's boobs. It seemed that she hadn't posed for these pictures but you could see they were hers and her face was recognizable in the pictures as well. Cassie was pissed.
"You asshole! I told you no pictures!" she spat at him. "Did you post any of these?"
Knowing the hot water he was in he stammered "N-n-n- no! I swear I haven't"
"Delete them" I directed. Cassie's fingers flew across the buttons.
"You were just going to show everyone in the locker room and brag about how you fucked my niece. Is that it?" I asked the boy.
"N-n-n-no, I swear. I was just...just...I just wanted them to look at later."
Softly I said as I leaned down to his ear "If I find out you are lying and you have posted them or I find out you are running your mouth about her...if you ever touch her or even dare to look her way, the last thing you will ever see will be my face as I slide the cold steel of my blade through your carotid artery. I will come into your room...at night...bleed you real quiet like and leave without a trace. I know how to do that and have done it more than once. Your parents will find your blood drained lifeless body in your blood soaked bed...dead as a hammer. Do you understand me?"
