Needless to say, I had a very restless night of sleep. I tossed and turned and woke up several times from dreams of Carrie stroking my cock. Each time I woke up I had a raging hard-on, which in normal times I would have stroked until I gave myself some relief. I didn’t though, even though Carrie would have never known. I think some part of me knew it would be better to wait. Better to see what my dominant little sister chose to do with my erections.

It was Saturday morning so I had intended to sleep late. Instead, I was startled as I rolled over to face the edge of the bed and bumped into someone sitting there. I propped myself up to see that it was my sister, and she had a wicked smile on her face.

“Good morning,” she said.

“Uh ... good morning,” I said with a cautious tone as I pushed myself up to lean back against the headboard.

“Did you sleep well, big brother?” she asked as she reached out to stroke my thigh over the covers.

“Well, to be honest, no,” I said. “I kept dreaming about you then waking up.”

“You didn’t play with my cock without permission, did you?” she asked with a concerned look on her face.

“No,” I said, a little too quick. I was kind of disturbed hearing her use words like ‘cock’, but kind of turned on as well. My morning wood was getting even bigger under the covers. Carrie looked like she was only wearing her usual panties and a crop top, so that wasn’t helping either.

With a smirk, she reached out and grabbed the covers over my torso and began to ease them down towards my feet. “I better check out the merchandise, just to be sure it’s okay,” she said.

“Carrie!” I hissed, pushing down on the fabric to either side of my legs with my hands to stop her. “Mom or Dad could come in.”

“Mom and Dad, as you like to call them, left early this morning and won’t be back home until tomorrow night. They left a note on the kitchen table. Now, move your hands, Mark.”

I stared at her for a moment, then lifted my hands. She laughed and started pulling again, which soon exposed my boxers underneath. There was a very obvious tent sticking up, and covered it with my hands as I felt my face begin to blush.

“Nyuh, uh,” said Carrie. “Hands off my cock, Mark. I already told you not to touch it without my permission.”

I sighed by blowing air out through my lips, and I’m sure my blush got even deeper, but I moved my hands off my erection. I put them down by my legs again and stared straight ahead, wondering how she would embarrass me next.

“How am I supposed to pee, then?” I asked with some frustration.

“Well ... I suppose I can let you pee without asking for permission. As long as you keep acting like a good boy, of course.”

“Such a brat,” I muttered.

“Hmmm,” she said, putting her finger up to her chin and exaggerating looking at my crotch. “It’s kind of hard to see with that underwear on. Take those off.”

“What? Are you serious?” I asked.

“Very,” was all she said and tilted her head as she stared at me, challenging me to refuse her.

I sighed again and reached down to slide my boxers off my hips and down my legs. As I pulled my feet up to take them off completely, Carrie grabbed them and threw them off somewhere to the side. Since that was all I had on while I slept, I was now sitting on the bed completely naked.

“You know what?” she asked with another devious smile. “I don’t like it being covered up like that when I come in here, so no more underwear while you’re sleeping. Got that big brother?”

“Yes,” I answered, sulking a little.

“Where are your manners, Mark? You were raised better than that.”

“Yes, ma’am,” I replied. My cock jumped a little as I said it, which Carrie didn’t fail to notice.

“See, everyone is happier when you do as you’re told.” As she spoke, she put her hand out and brushed my knee with her palm, making me jump a little.

“Shhh. It’s okay, big brother,” she whispered. She moved her hand up my thigh, causing my already straining prick to somehow get even harder. My scrotum clenched up tighter as well. The anticipation was killing me, and I’m not sure I had ever had so much blood rush into the tip as there was right now. It looked like a giant purple mushroom, and the slit was open just a bit with drop of liquid oozing out.

Carrie scooted up closer to me on the bed, her body pressing against my thigh as she leaned in. I could feel the heat of her body, the softness of her skin, and it sent a shiver of anticipation down my spine. Her left hand began to explore, starting at my knee and slowly trailing up my leg. The touch was light, her fingers and palm barely brushing against me, but it was enough to make me shiver. She took her time, teasing me, her touch feather-light as she moved up my thigh, brushing against the hair. It made my breath hitch in my throat, and sent electric shocks of pleasure through my body.

As her left hand skipped over my groin, I let out a soft groan, already aching for her touch. She continued exploring, her hand moving across my abs, which tensed under her touch. I could feel the cool air on my skin where she had touched, the contrast to her warm hand making me even more sensitive. Then, finally, her fingers wrapped around the base of my cock, squeezing with a firm grip. “Oh my God...” I breathed, the sensation of her hand on me almost too much to bear. I could feel every vein, every ridge, her touch firm yet gentle, and it sent waves of pleasure coursing through me.

At the same time, her right hand began its own journey, mirroring the left, brushing up my other thigh. I could feel small callouses on her fingers, a testament to her tennis playing, and the slight roughness only added to the sensation. As her right hand reached the top of my thigh, she extended her pointer finger, touching the very tip of my cock. I jumped slightly at the contact, the sensation of her finger on the sensitive head almost too intense. Holding my throbbing member steady with her left hand, she used her right to gather up the small drop of pre-cum that had formed at the tip.

She held her finger closer to her face, studying it for a moment, her grip on me never wavering. Staring into my eyes, she stuck out her tongue and slowly licked the tip of her finger, her eyes never leaving mine. Then she closed her lips around her finger, nursing on it, tasting me. I could feel the pleasure building in my stomach, my body tensing as a wave of intense pleasure rushed through me. I flexed my hips upwards, making my cock move through her hand. My breath came in ragged gasps as I tried to hold on, to make the sensation last.

“Oh fuck, Carrie,” I gasped. My fists gripped the sheet below me, and I felt like I might blow my load right then and there. My mind filled with thoughts of her stroking me again, making me cum on her leg again like last night.

Instead, she kept the grip on the base of my shaft and said, “Lay flat again.” I scooched my body down the bed and lay my head flat on my pillow. Then she stood up and put a knee up on the bed, proceeding to straddle my thighs. I could see now that she had on white panties with a little red bow on the waistline. The white material gripped her mound, and it was all right there, right past my straining prick. Everything I dreamt about was right there, hidden beneath that thin layer of fabric. My mind raced with thoughts of what I could do to her, and how I could make her feel as good as she was making me feel.

She let go of my cock and reached up with crossed hands to grab the crop top and pull it up and over her head. Then she reached down to grip the base of my boner again, while she grabbed my ballsack with the other.

“Fuck! Fuck, Carrie!” I cried out as she squeezed my balls inside their sack. They were sensitive, and I was not used to them being handled like that, even though she wasn’t squeezing that hard. I looked up to see her smirk, then she let go of my package and slid further up until she was sitting on my stomach.

“I want to see if you know how to behave, big brother,” she said as she looked down at my face. “If you do as you’re told, then I will reward you. If you don’t behave then I’m going to cut you off for a week. Do you understand?”

I nodded and said, “Yes, ma’am.”

“So be very still and don’t move a muscle. Don’t say anything. Don’t do anything. Be a good boy for me, Mark. Nod once if you understand.”

I nodded, then swallowed in anticipation, having no idea what was about to happen.

“Arms at your side with your palms flat. Remember, no talking or moving.”

I put my arms down my side and my palms flat on the bed, right next to my hips. Carrie smiled then slid further up, until her knees were on either side of my head and her panties were hovering right over my face. I saw her reach to grip the backboard of my bed with both hands, using it to let her hover exactly where she wanted.

“Do you like my little pussy, Mark?” she asked in a sweet voice. “I bet you wish you could taste it, don’t you? Stick your tongue in and swirl it all around?”

Carrie’s voice was like a sweet melody, her words sending shivers down my spine. I could feel the heat radiating from her pussy, could smell her arousal, and it was intoxicating. The scent was a heady mix of musk and the lingering traces of her body wash, a scent that was uniquely hers. It made my mouth water and my cock throb like a bass drum.

I nodded, unable to speak, my senses overwhelmed by the scent of her arousal. It was a scent that was driving me crazy, a scent that was making me want her more than ever.

She laughed, a soft, sultry sound. “You’re such a good boy, Mark,” she said, her voice low and husky. “But you have to earn it. You have to prove that you can behave.”

With that, she slowly lowered herself a little more, her panties brushing against my nose as she stared down at my face. It was a barely there touch, a tease that was driving me insane. I could feel the dampness of her arousal, could smell her musky scent, and it was driving me crazy. I wanted to touch her, to taste her, but I knew I couldn’t. I had to behave.

“Take a big whiff,” she ordered, her voice full of desire. “Breath it in, big brother. Do you like the smell of my pussy? Do you want to use your tongue to do disgusting, perverted things to your little sister’s pussy?”

I nodded, my heart pounding in my chest. I did like it. I loved it. I loved the anticipation, the tension, the thrill of not knowing what was going to happen next.

She smiled wickedly, her eyes sparkling with mischief and desire. “Good boy,” she purred. “But I want to hear you say it. I want to hear you beg for it.”

She ground her pussy against my nose, the damp fabric of her panties leaving a slight sheen on my skin. “Tell me, Mark,” she whispered, her voice a low, seductive purr. “Tell me what you want to do to me. Use your words, big brother. Let me hear that dirty mouth of yours.”

I took a deep breath, the scent of her arousal filling my lungs, making me dizzy with desire. “I want to taste you, Carrie,” I managed to say, my voice hoarse with need. “I want to rip off your panties and bury my face in your pussy. I want to lick you, to suck on your clit, to feel you grind against my tongue.”

She moaned, a soft, needy sound that sent a jolt of pleasure straight to my cock. “That’s it, Mark,” she encouraged, her hips moving in a slow, sensual grind against my face. “Tell me more. Tell me all the dirty things you want to do to me.”

I could feel the wetness of her arousal through the thin fabric of her panties, could see the dark stain spreading as she ground against me. “I want to fuck you with my tongue,” I said, my voice gaining confidence as I saw the effect my words were having on her. “I want to feel you come in my mouth, to taste your cream as it coats my tongue.”

She threw her head back, a low moan escaping her lips as she continued to grind against me. “Yes, Mark,” she panted. “That’s what I want. I want you to eat my pussy like a starving man. I want you to make me come so hard that I see fireworks.”

I could feel my cock leaking pre-cum, the tip throbbing with need as I listened to her dirty talk. I wanted nothing more than to reach up and tear off her panties, to plunge my tongue into her wet, waiting pussy. But I knew I had to wait, had to behave, had to earn it.
