TABOO novel Chapter 22

" Fuck." I groaned with my hand on my cock as I stroked hard. 

  I couldn't believe I was doing this. Watching my sister's twerk video on Snapchat and touching myself to it. I moaned shamelessly, biting my bottom lip while trying not to moan out loudly. Her big ass bounced so perfectly as she whined her waist. She was wearing a tennis skirt in the video and I could see her beautiful thick thighs. I imagined my hands all over her thighs. I imagined grabbing her big butt as she rode my cock. 

" Fuck. Oh fuck." I moaned silently as I stroked my cock faster and harder. 

  I was close and I could feel my orgasm at the tip of my dick. I was stroking my cock to my sister's twerk video and it felt so sinful and amazing at the same. 

" Oh fuck, Cassie. Just like that." I groaned as I imagined my sister's lips around my dick as I deep-throated her. What I've always wanted. To slide my dick inside her mouth and her warm pussy. 

  The thought drove me over the edge and I orgasmed. I took a deep breath as I grabbed my shirt to clean my chest that was stained with my cum. Cassie was my half sister. We were related by birth. My mother and my father had me about a year later after their wedding. Four years later, they divorced. Mom married Cassie's father six months later and they had Cassie not quite long after their wedding. So it was pretty obvious, my mother was fucking Cassie's father while still married to my dad. 

  Cassie and I aren't really best friends. She was this hot girl who was an Instagram influencer. She posts different twerk videos of her twerking in her dorm room on Instagram, Snapchat and even tiktok. I've always wanted to fuck my half-sister since she was 18 which was too years ago. But the thought was shameful and disgraceful. How could I want my sister? 

  Since she was Forbidden and way out of reach, I followed her social media accounts and watched her twerk videos. I couldn't concentrate and think at times as I watched her butt shake and bounce. All I could do was touch myself while watching her like I just did. It's been months since I last had sex. About four months now. My girlfriend, Regina, broke up with me because she thought I wasn't good enough for her. I wouldn't blame her. Everytime we had sex, I always imagined my sister beneath me and on some weird occasions, I even moaned out her name. Regina couldn't tolerate the habit and she later found out I've been face fucking her all this time. She was disgusted and asked me never to call her again. I wasn't really planning on doing that in the first place. 

 I got out of bed and threw my sperm stained shirt on the hamper as I walked out of my room. I needed to eat something. I have been in my stepfather's house since I just graduated college. I worked for his company and I hated it sometimes. It's not like the job was bad or the pay was bad, it's just I never really liked Cassie's father. I felt like he was the reason my father was no longer married to my mother. Which was true. 

  Last night, I heard Cassie was coming home from college today. As much as I wanted to see her, and desperate to see her, I couldn't. Especially when I think of the times I masturbated to her twerk videos. I was ashamed. What would she do if she found out I pleasured myself with the image of her in my head and even fuck faced my girlfriend with her image in my head all the time. I couldn't help it. I wanted my sister and it's fucked up. 

  Cassie was nothing like me. I might be her brother and older than her but I was out of her league. She had guys wooing her every other day and over 100k Instagram followers and 400k tik tok followers. She was hot, and I was nothing like the guys she dated or the guys she would date. I was nobody. At my age, I barely ever partied. I mostly spent my time indoors doing things like studying and hating my step dad. I was mostly introverted. Cassie was extroverted. Storming different parties in college and posting her new boyfriends every two months. How did I know? She lived almost half of her life on social media. 

  I made cereal and ate as I scrolled through Cassie's Instagram pictures. My sister was beautiful. Brown curly hair, beautiful grey eyes. She was petite with small breasts and a nice bubble butt. She was everything I've always wanted to fuck. Thinking about it made it all weird. Why would anyone think about fucking their sister? My mother's daughter. I exited Instagram and turned off the screen of my phone. I couldn't do this anymore. 

" Hey, Luke." My mother called my name as she walked into the kitchen.

" Hey Mom."

" Can you go pick up Cassie today? She is coming home today to spend the holidays. You know it's Thanksgiving the day after tomorrow." 

  I sighed and dropped my spoon in annoyance. 

" What about David?"

" You know he's not around. He went out to buy things for Thanksgiving."

" It's Thanksgiving, not Christmas." I sighed. I should avoid my sister. That was the only way I could not try to act on my thoughts. 

  Cassie saw me as her big brother. A big brother she could rely on and I shouldn't ruin that for her by thinking about fucking her. She was pretty sweet, liked to laugh and was always touchy around me. I have told her playfully a lot of times to stop touching me especially when I wasn't wearing a shirt, but she just laughed and waved it off like it was nothing. I needed to earn a lot while working for David's company and then I would rent my own apartment. Hopefully, I wouldn't see much of Cassie. 

" I'll try."

" Don't try. Please pick her up."

" I'll try. Where are you even going?"

" To the office. I needed to run a report today before Thanksgiving." She said. " See you later, Luke. Be nice to Cassie."

" I'm always nice to her."

" I know." Mom giggled as she left the house. 

" Fuck." I cussed out loudly.

  I watched a football match in the living room while lying on the couch. I didn't know how, but I fell asleep. I woke up later in the evening from Cassie's loud booming voice. 

" Luke!" She called my name as I jolted to a sitting position. 

  Cassie wore a black tennis skirt and a white halter neck cropped top. Fuck, she looked prettier than I remembered. She smiled, so lively as she surprised me by plopping down on my lap. 

 Shit!

" Oh. Hey, Cas." I greeted her. I let my hands fall on my side as I tried not to look at her beautiful breasts spilling out of her top. 

  David, Cassie's father walked in. 

" Hey David."

" You forgot to pick her up. Your mother said she told you to."

" I'm sorry. I really did forget. I fell asleep." I said. 

" It's fine. You're forgiven." Cassie said and wrapped her arms around my neck. 

  David rolled his eyes and walked to his room. 

" How was school?" I tried a conversation.

  Cassie's tennis skirt was too short. I could feel her soft bare butt on my lap even though I was wearing sweats. Was she even wearing any panties? I wanted to ask her.

" School was good. I missed you. I texted you on Instagram, you didn't message back."

" Fuck. Sorry, escaped my mind. I was working and all." I said and looked up at her face that was dangerously close to mine. God I wanted to kiss her. 

  I stared at her red lips and she smiled. 

" You're so sweet. Tell me what have you been doing?" She asked and stood up from my lap as she took my hand in hers. 

" Nothing really. You know since it's Thanksgiving week, there's not much to do at the office." I said. " Let me take that for you." I collected her bag from her hand and we walked toward her room.

 Her hand was still laced with me. We stopped outside her room and we entered inside together. I barely ever enter this part of the house. Her room was close to mine but I made sure I stayed away from it. Through the thin wall, I heard her moan some nights and I presumed she was probably touching herself. The thoughts alone made me jerk off too. It was insane. 

  I dropped Cassie's bag on her bed and turned to leave, but she stopped me with a question.

" How's your girlfriend? And please shut my room door. You know I don't like leaving it open." 

" Yeah. Right." I mutter and shut her bedroom door slightly. I didn't want our parents to think something was going on. 

  They wouldn't think that, but my dirty thoughts were racing to Forbidden areas. 

" So how is your girlfriend, Luke?" Cassie asked as she zipped down her tennis skirt from behind her. 

  It fell to the floor and I looked away at once, not before seeing a small seductive smile on Cassie's lips. 

" You know you can look right?" Cassie said. 

  I bit my lip and turned my head toward her. Fuck she was wearing a red lace thong. My eyes gazed from her head to her toes as I drank in every part of her. God, she was sexy. I blinked my eyes and looked away again. How could I openly check my sister? This was madness. 

  Cassie chuckled. " You still haven't answered my question, Luke. What's up with your girlfriend?"

" She's good I think."

" You think?"

" We broke up."

" Ooh. You did? You guys were so into each other." Cassie said as she approached me. She stopped in front of me and turned around. 

  Her big butt was nearly touching my crotch. 

" Help me untie my top, will you?" 

  Was she aware her father was just down the hall? In his bedroom. What if he walked in and found his daughter naked with her half-brother in the room? I definitely couldn't explain that. I took a deep breath as I stared down at her butt with her red lace thong buried deep in her butt crack. 

" Fuck." I muttered and regretted it at once. 

" I'm sorry." I apologized and untied the strap of her top around her neck. 

 Cassie chuckled. " It's fine." 

  Cassie stepped away from me and turned around. The halter neck fell down a little, exposing Cassie's firm little tits. I couldn't look away, not with the way she was staring at me. Cassie held the hem of her top and pulled it over her head. Our eyes met again, and she was biting her bottom lip. She smiled a little, with my eyes on her erect pink nipples and on her lips at the same time. 

  She looked down at her breast and pinched her nipples. 

  Fuck!

" I wonder why they're so hard." She whispered.

  I need to get out of here. She was seducing me and succeeding. 

 I cleared my throat and Cassie looked up at me, with her fingers still pinching her nipples. 

" I should leave you to get changed." I turned around and hurried out of her room before I did something we both might regret later. 

 The following day, I avoided Cassie by staying in my room. That night, we wanted to have a family movie night and it would be disrespectful if I decided to skip out on this one. We sat on the couch opposite the big screen in the movie room. We had a movie room, different entirely from the living room. My mom sat next to David with her head on his shoulder and a blanket around herself. Cassie hadn't shown up yet. I wore sweats and a t-shirt while I sat next to mom. Suddenly the door opened and Cassie walked in. The game of thrones displayed boldly on the projector. 

" Hey honey." Mom called Cassie with a smile on her face. She had a blanket around so I couldn't tell what she was wearing.

" Hey Mom. Hi Dad."

" Hey honey. Come on." 

  Cassie walked towards the couch and I stared at the movie already projected. Cassie surprised me by sitting on my lap again. My parents didn't think much of it. They were okay with Cassie and I being weirdly close and even sitting on my lap. They believed we're both siblings and nothing could go wrong. 

  Everything would definitely go wrong. 

" Hey Luke. Ooh game of thrones. It's been long I saw this movie." Cassie said as she sat properly on my crotch, grinding her ass on my dick on purpose.
