I stared at my last slice of pizza, wondering if it was wise to overload my system with more cheap carbohydrates. A loud burp escaped Cindy’s mouth after she’d finished her large coke. We both laughed, realizing we had definitely eaten too much.
“We better hide the pizza boxes,” she said with a sigh while rubbing over her taught belly. “Mum will go ballistic if she finds out we decided to order pizza instead of using her prepared meals.”
“She will understand,” I replied. “They have their outing, so why can’t we have one too?”
Cindy pulled me from my chair and gently pushed me in the direction of the luxurious sofa. “Let’s get more comfortable and talk a bit about our future.”
With ease I swung her body around and pulled her into a hug. Her heels made it possible to look her straight in the eyes. Even with the dim lights, the cerulean blue of her eyes made my heartbeat faster. Our kiss was tender, acknowledging our strong bond.
“Casper,” she whispered, “What will I do without you?”
It had been a rollercoaster; the last twenty-four hours definitely had changed my life. The amazing woman I was holding in my arms told me life could be fantastic, but unfortunately, she was my sister. Well, technically speaking she wasn’t, and we probably could get away with it, but at what cost? I was shocked to see tears running down her cheeks, fearing we had gone too far already.
“I don’t want this to stop,” she said meekly.
“We still have tomorrow,” I replied soothingly, “and perhaps you can free yourself on mum and dad’s bridge evening. At least we have a few days extra before Valentine’s Day.”
She sniffed and pulled me even closer. “I guess I can ask Claire if she wants to swap with me at Jolie’s.”
It was strange that hearing her name made my heart beat a little faster. “I didn’t know she works at Jolie’s as well.”
My sister pulled away from the hug and as she guided me towards the living room she said, “She helped me to get in. Actually, it would be perfect, if she is willing to swap, because it means you can’t double date us.”
“Hold on,” I said while I sat down facing her. “You mean I should start dating her before Valentine?”
“Oh Casper,” she said while she patted my thigh. “It’s time you let her know you like her.”
My head was churning. I needed more time to think about it and I doubted whether I could deal with her and with Cindy at the same time.
“Come,” Cindy said soothingly as she readied herself for me, “lay your head on my lap. Then we talk further.”
It had been ages since she had done this, and I remembered the last time when she’d helped me deal with one of the bullies in primary school. With a healthy dose of sarcasm, I lowered my head onto her lap but as soon as I got comfortable, her hands started to roam through my unruly hair, which was actually quite soothing.
Her voice sounded different, more neutral and, almost devoid of emotion, when she said, “I want you to think back to the last conversation you had with Claire.”
I remembered Claire’s pleasant voice and her sweet smile. At that time, I felt a little uneasy because of my sister’s blatant procrastination. I was pleased we’d found a common interest so we could have a decent conversation. Then it struck me; I was slightly annoyed when Cindy arrived, which ended the relaxed chat with Claire quite abruptly. I had dismissed Clair’s pensive expression when we drove back home, but I still wasn’t convinced she was thinking about our conversation, it easily could have been musing about other things that occupied her mind.
“Alright,” I said slowly, as I tried to summarize the event, “we had a short chat.”
“And you felt at ease, didn’t you?” she said softly.
Her observation was spot on! It was indeed the first time Claire and I talked without any awkwardness. My mind was still processing the significance of it all, especially because of the fact that Claire was a woman, moreover a spectacularly beautiful one!
“Do you like Claire?”
“Yes.” Again, the answer left my mouth before I’d time to mentally process it.
Cindy chuckled, presumably because of my shocked expression. “I like your frankness, Casper. It makes you trustworthy and believe me; women will adore you for that.”
I huffed, not knowing what to think of it.
Cindy reached for the remote and switched on the TV. I was slightly disappointed our little chat had ended. I yawned and it dawned on me I was actually completely finished for today. Her hand was still playing with my hair, which felt pretty good.
My back was aching, and my tongue was about to fall out of my mouth, but I kept on pressing it flat against her clit, trying to prolong her climax as long as possible. I smiled inwardly when I remembered how I persuaded her to give me one more lesson before our parents came home. It was early afternoon and there was still plenty of time.
I loved the way she lazily roamed her hands through my hair and as soon as I heard her deep satisfying sigh, I knew I could stop. My desire to celebrate my success coursed through my body and I nuzzled her soft pubic hair. Her skin was much warmer and had a sheen of perspiration that I totally adored. With soft tracing kisses I moved upwards and decided to continue my kissing journey over her left breast, whereby I didn’t forget to briefly suckle on her delicious fat nipple.
“Oh god,” moaned Cindy, “You’re such an awesome lover.”
I finally had reached her mouth and pecked those soft lips once before I said jovially, “Practice makes perfect.”
Her laugh sounded happy. “You’re a quick learner,” she admitted, “I’ll give you that.”
My raging erection was nestled between her legs, and I hoped we could finish our session with a ‘Grand finale’. My breath hitched when she rested her feet on my buttocks. Was she be ready for the next step?
Her smile was nervous when she said, “I guess we could go for it.”
I stared at her, and I sensed her doubt. “Only if you want it.”
“Oh, I’d loved to,” she replied softly, “I really long for it, Casper.”
My heart skipped a beat when I suddenly remembered we were about to have sex without any protection. “I need to get a condom,” I blurted.
Lazily she shook her head, “No need, I’m on the pill.”
It was strange. I was lying on the most desirable woman, completely naked, contemplating whether we would take it to the next level. We both kept on staring at each other, as if something was withholding our decision.
It was Cindy who finally initiated the next step of our relationship. Slowly she spread her legs, allowing me free access to her inner sanctum.
“Go slow,” she whispered when she grabbed my cock to align it with her pussy’s entrance. I shivered when I felt the tip of my throbbing girth slide over her silky slippery folds. Her eyes grew bigger the moment I was about to enter her pussy.
My legs were trembling as I tried to control the penetration of her very narrow entrance. Our eyes were locked together when I pushed a little harder to overcome her pussy’s resistance. Suddenly her expression changed into fear and with a suffocating howl she tried to push me off her body. Her scream was deafening. “NOOOO!”
Shocked, I stared at Cindy who had moved into a fetal position. Carefully I draped the duvet over us, and I slowly snuggled up to her. She was crying softly and the only thing I thought I could do was gently rub her back.
“I’m sorry,” she said hoarsely.
“There’s no need to apologize,” I said soothingly, “I understand.”
“Hold me, Casper,” she whispered while she moved her trembling body against mine.
“I’m here for you,” I replied.
She sniffed while I slowly caressed her, and I decided not to say anything. Clearly our feeble attempt to make love had triggered some real bad memories for her. I shuddered internally when I realized that Jack’s attack had made it even worse. It explained her insecure behavior when we were discussing it but then it hit me; she must have been struggling for much longer! I wouldn’t be surprised that she’d probably been freaking out, every time ‘the moment’ was there. It was strange because she really wanted to make love to me, but her body rejected me as soon as I tried to force myself into her tight channel.
Her ragged breathing finally calmed down after I had held her for quite a while. I rubbed her back and asked, “Are you up to facing mum and dad?”
She nodded. “I’m fine. Thank you.”
“Good, they will probably be here within half an hour or so.”
“Casper?” she asked with a small voice, “can we just forget that just happened?”
I kissed her forehead to buy some time to formulate an answer. My heart was screaming to resolve this issue, but I knew Cindy was far from ready to deal with it.
“Of course, sweetheart,” I answered soothingly.
Slowly she untangled herself from me and walked like a zombie out of my room. I felt sad seeing her dejected like that and I knew I had to help her. Slowly it started to dawn on me that Cindy had hoped it wouldn’t happen to us. My heart was thumping in my throat when I suddenly understood the severity of her problem.
I was sitting at my desk, staring at the little Christmas lights on our neighbor’s house. I had been studying for the end of semester tests, although it had been hard to keep my attention on it. My thoughts always kept wandering to my sweet sister.
