Chapter 5: Monday Morning

It was early the next morning when I pulled the car out of the driveway, headed towards our junior college. Carrie sat in the passenger seat, her outfit consisting of a short skirt and a crop top that showcased her assets perfectly. Mom and Dad had still been home when we left, so she had mostly been well-behaved so far. She turned to me, a mischievous glint in her eye, and slowly pulled her skirt up, showing more and more of her thighs.

“What do you think Mark? Do you think I’m wearing panties right now?”

I glanced over at her nervously, trying to keep my eyes on the road and not the creamy skin that she was showing me more and more of. “Are you crazy, Carrie? You can’t be going out in public without panties on.”

“Keep your eyes on the road, big brother,” she teased, her voice husky with desire. She unbuckled her seatbelt and turned to face me more, putting her left leg up on the center console. I glanced over at her and saw that she did not, in fact, have panties on. I could see her pussy under the skirt, then I could see it all as she pulled the skirt up and bunched it around her waist.

Carrie started to stroke herself, her fingers gently parting her folds, teasing her clit in slow, deliberate circles. “God, Mark, I woke up so fucking horny this morning,” she moaned, her voice breathy and desperate. “I wished your tongue was buried inside me, licking me, tasting me. I wanted you to start at my ass and lick your way up to my clit, slowly and gently at first, then faster and harder as I get closer to cumming. I want to feel your tongue inside my pussy, fucking me with it, making me scream your name.”

I swallowed hard, trying to focus on the road as my cock ached for release. “Carrie, you’re driving me crazy,” I managed to say, my voice hoarse with desire.

She smiled wickedly, her fingers moving with practiced ease as she built her pleasure. “That’s the idea, big brother,” she purred. “I’m enjoying this too much to rush it. Imagine this ... I’m soaking wet, my pussy lips are swollen and sensitive, and your thick cock is waiting ... ready to start spreading me wide open. I can feel the head of your cock pressing against my entrance, and I’m begging you to fuck me deep and hard.”

When we stopped at a light, she nudged my arm with her foot, her eyes locked onto mine as she lifted her crop top, exposing her perfect tits. Her nipples were hard, begging for my mouth, and I reached my hand out, eager to stroke it with my fingers. But she pushed me back, a playful smirk on her lips.

“Uh-uh, big brother,” she teased. “You don’t get to touch until I say so. For now, just watch and imagine how good it would feel to be inside me. Imagine my tight, wet little pussy wrapping around your cock, squeezing you, milking you for all you’re worth. Feel the head of your cock as it pushes past my tight entrance, inch by inch, stretching me, filling me completely.”

With that, she pushed two fingers into her slit, her other hand moving to stroke her clit. She moaned, a deep, throaty sound that sent shivers down my spine. “Fuck, I’m so wet, Mark,” she said, her voice husky with desire. “I can feel how tight I am, how much I need to be filled. Your cock would feel so good inside me, stretching me, fucking me deep and hard.”

I was startled out of my thoughts by the car behind us honking. I realized that the light had turned green, so I tore my eyes off my sister’s pussy and started driving down the road again. Carrie giggled, then continued tormenting me.

“Imagine the tip of your cock rubbing against my G-spot, Mark, making my eyes roll back in my head. I want to feel every vein, every ridge of your cock as you slide in and out of me, coating that hard shaft in my juices.”

I could see her fingers moving in and out of her pussy, coated in her arousal, and it was all I could do to keep my eyes on the road. “Carrie, please. You’re going to make me wreck the car,” I pleaded, my voice ragged with need. The car started chiming, warning about her seat belt not being fastened.

She looked at me, a cruel smile on her lips. “Oh, but you love this, big brother,” she said, her voice firm. “I can see how hard your cock is right now. It’s about to burst through those shorts.”

I reached down with one hand, moving my shorts around to try to give my straining prick some more room. I think it only made it worse, especially since Carrie just kept going, describing exactly how I would be fucking her for the first time.

“You’re on top of me and now your cock is so deep inside my pussy. I’m wrapping my legs around you, pulling you deeper, helping you hit that sweet spot deep inside me. Can you feel my heels on your back big brother?”

She increased the pace of her fingers, her breaths coming in short gasps as she chased her orgasm. “God, Mark, your cock would feel amazing inside me,” she moaned, her body tensing and shaking. “I want you to fuck me so bad. I want to feel every inch of you, stretching me, filling me completely. Imagine the sound of our bodies slapping together, the smell of our sweat and sex filling the air. I want to hear you groan my name, feeling my big brother’s cock throb and pulse inside me.”

I could see the flush spread across her chest, her nipples hardening even more under my gaze. Her breaths came in short gasps, and I could tell she was close. “Oh my God, Carrie. You’re so fucking sexy. Jesus.”

She looked at me, a wicked grin spreading across her face. “Almost there, big brother,” she panted. “Now you’re on your back, and I’m riding you cowgirl style, bouncing up and down on your cock, using your body for my pleasure. I want to feel you grab my hips, guiding me, helping me ride you faster and harder. I reach down and twist both your nipples so fucking hard. It makes you scream my name again. I want to feel your cum dripping out of me, coating my thighs as I ride you into oblivion.”

“Jesus, Carrie. Where are you getting this shit? Are you watching porn?” I was turning off White Bridge Road into the parking lot, frantically looking for a spot to pull into that was away from everyone else.

Just as I pulled into a spot in the back corner, her body tensed, and she let out a loud moan as her orgasm washed over her. “Fuck, Mark,” she screamed, her body shaking with the force of her release. “Oh fuck! I’m cumming so fucking hard, big brother!”

I turned and watched in amazement as her body writhed around in the passenger seat. Her body clenched as she continued to cum, her two fingers still working in and out of her beautiful pussy. Finally, the spams subsided and she collapsed back in the corner of the seat, breathing hard. Her left foot was now draped across the console with her foot lying in my lap. I stroked her lower leg gently, trying to calm her.

“Shhh. It’s okay, Carrie. Jesus that was amazing. I’ve never seen anything like that in my life. You are so fucking beautiful and sexy.”

She leered at me then pulled herself up. She leaned towards me and brought her fingers to my mouth, pushing them inside. “Lick them clean, big brother,” she commanded. “Taste how much I want you.”

I obediently sucked her fingers into my mouth, tasting her delicious cream for the first time today. My cock was throbbing with unfulfilled need. I could feel her eyes on me, watching my reaction, and it only served to heighten my arousal. I looked at her with desperation on my face as I looked around to make sure nobody was nearby.

“Can I cum too?” I asked, squeezing the bulge in my shorts.

Carrie just looked at me with her evil little smirk and shook her head. “Nope. Maybe later, Mark. It’s always better to let it all build up, isn’t it?”

“You’re such a brat,” I muttered. Carrie just giggled again.

We sat in the car for a few minutes, the engine idling as we caught our breath. Carrie pulled her top down but kept her skirt pulled up, exposing her pussy to me. I couldn’t take my eyes off her beautiful slit. She was so fucking beautiful, and the way she was touching herself, so confident and sure, drove me wild.

“Carrie,” I started, my voice still hoarse with desire, “why are you doing this to me? Why do you want to control me so much?”

She looked at me, a soft smile playing on her lips, and she continued to stroke her pussy, her fingers moving in slow, deliberate circles around her clit. “Because I love it, Mark,” she said, her voice gentle but firm. “I love seeing you so uncomfortable, watching you beg. You’re so submissive, kind of like Dad is with Mom. It turns me on, seeing you like this, knowing that you’re mine to command.”

I watched as her fingers dipped inside her, coating themselves in her arousal before returning to her clit, stroking and teasing. “But it’s more than that,” she continued. “I’ve always loved you, Mark. You’ve been my rock, my confidant, my best friend. And now, to find out that we’re not actually related, it’s like a dream come true. I can have you any way I want, and I plan to.”

She increased the pace of her fingers, her breaths coming in short gasps as she built herself back up to another orgasm. “I think you enjoy it, Mark,” she said, her voice a low purr. “I think you enjoy being told what to do, being made to submit. I see it in your eyes, the way you look at me when I’m in control. You’re unwilling to admit it, but I know you love it.”

I watched, mesmerized, as her body tensed and her breaths came in short gasps. “I want you to agree to do as you’re told, Mark,” she said, her voice firm. “I want you to be a good boy for me. In return, I promise you’ll have mind-blowing orgasms. You’ll never have to masturbate again because I’ll make sure you’re always satisfied. All you have to do is submit to me, and I’ll take care of the rest.”

I watched her stroke her pussy, her fingers moving in and out of her wetness, coating themselves in her arousal. I could see how turned on she was, how much she was enjoying this, and it made me want to please her even more.

“Please, Carrie,” I begged, my voice hoarse with need. “I’ll do whatever you want. Just tell me what to do. I’ll be a good boy for you.”

I couldn’t believe the words that were coming out of my mouth, but as they say, “A hard dick has no conscious.” I just knew that if I did what she asked, I had a chance to fuck Carrie, and that was the thing I wanted to do more than anything. Damn the consequences.

She smiled, a wicked, satisfied smile, and nodded her head. “Good boy, Mark,” she purred. “I’m glad you see things my way. Now, let’s get out of here and find somewhere more private. I have big plans for you today.”

We got out of the car and walked together through the back parking lot, headed towards the Richland Creek Greenway which had an entrance in the back corner. I didn’t really use the trail much, but Carrie liked it when she wanted to go for a run sometimes if she needed to wait for me to get out of class. This late in the spring, the foliage was getting pretty thick, and after going about a quarter of a mile, Carrie turned off the paved part onto a small trail that led through the woods. It winded around a bit before it stopped at a pile of rocks. Carrie gestured for me to follow and climbed up between two of the boulders, where there was an empty area with a dirt floor.

“What is this place?” I asked, looking around nervously.

“I think they piled the rocks up here when they were building the golf course next door,” Carrie answered. “I found it a few months ago and I’ve never seen anyone else here. Now ... enough talking. Are you still my good boy?”

I nodded my head and said, “Yes, ma’am.”

“Very good,” she said with a smirk as she dropped her backpack and sat down on a smaller rock. “Get those clothes off.”

My eyes went wide. “Jesus, Carrie. What if someone sees us?”
