Sunday morning, I woke up with a start, my body already tense with arousal. The room was filled with a soft, warm light filtering through the curtains, casting a gentle glow on the familiar surroundings of my bedroom. As my eyes adjusted, I realized I was naked, my body exposed to the cool air. I also realized my cock, already rock-hard, had a hand wrapped around it ... a hand that was not mine.
I looked down to see Carrie sitting next to me, her hand gently stroking my length. She was also completely naked. Her touch was firm yet delicate, sending shivers down my spine. I let out a soft moan, my hips involuntarily bucking into her hand. Carrie looked up at me, a wicked smile playing on her lips.
“Good morning, big brother,” she purred, her voice a sultry whisper. “Did you sleep well?”
I could only nod, my breath already coming in short, ragged gasps as she continued to stroke me. I looked down at her hand, watching as her fingers wrapped around my shaft, her grip firm yet gentle. Her thumb brushed over the sensitive tip, and I sucked in a sharp breath, my hips jerking involuntarily. Pre-cum beaded at the slit, and to my shock, Carrie leaned down and flicked her tongue out, licking it off. I had never felt anything like it—the wet heat and softness of her tongue. It was a sensation that sent electric shocks through my body, making my cock jump and pulse in her hand.
“Mmm, not bad at all,” she murmured, her eyes never leaving mine, a wicked glint in them. “But I want more than just a taste.” She swirled her tongue around the tip once more, then pulled back slightly, a mischievous smile playing on her lips. “I want to feel you, all of you, but not like this.” She squeezed my cock gently, stroking it slowly to emphasize her point. “I want to ride you, Mark. I want to feel that big, hard cock up inside me, filling me up.”
My cock twitched in her hand, growing even harder, if that was possible. The blood was pounding through it so intensely that it felt like it was going to burst. The vein along the underside pulsed, and I was sure that if she kept touching me like that, I would lose it. The sensation of her hand on me, her words in my ear, it was all so fucking hot. I never knew that anticipation could be so torturously pleasurable.
“This is it,” I thought. “She’s going to ride my cock!” I was so sure of it that I was about to blow a load right then and there. With supreme self-control, I managed to not cum, but the effort made a shiver run down my body from my head to my toes.
“First, though, it’s time for you to pleasure me, big brother.” She stopped stroking me, and I let out a whimper of protest. Carrie chuckled, a low, throaty sound that sent a jolt of desire through me. She climbed up fully on the bed, straddling my hips, her bare pussy pressing against my cock, making it lay flat against my lower belly. I could feel her heat, her wetness, and it drove me wild. She began to grind against me, her hips moving in a slow, teasing rhythm. My hands clenched the sheets, my knuckles white as I fought the urge to grab her, to take control.
“Carrie,” I gasped, my voice hoarse with need. “Please...”
She leaned down, her breath hot on my ear. “Please what, big brother? What do you need?”
“I want to cum,” I admitted, my face flushing with embarrassment. “I want to feel you...”
Carrie sat up, a triumphant smile on her face. “Not yet,” she said, her voice firm. “I’m going to keep playing with you first.”
She slid her slick, warm pussy up my body, leaving a trail of her cream along my belly, her arousal marking me as hers. My cock ached, throbbing with need as she straddled my chest, her knees digging slightly into my sides as she hovered just above my face. I could feel her heat, her wetness, and it drove me wild. She was so close that I could smell her, that musky, unique scent that was entirely her own. I looked up at her, my eyes locked on her pussy. It was bare, except for a trimmed patch of pubic hair above it, and I could see how wet she was, her slit glistening with arousal. The sight and scent of her were overwhelming, making my mouth water with anticipation. I had been dreaming about this moment since little sis developed her tits years ago at puberty.
My mouth watered as she reached down and gently spread her inner lips with two fingers, revealing a sight that was both intimate and incredibly erotic. Her inner lips, a deep, rich shade of brown, were folded back against her outer lips like the delicate wings of a butterfly, exposing the most perfect, bright pink passage I had ever seen. The contrast was stunning, a dark frame around a bright, glistening center that was dripping with her arousal. It was a sight that seared itself into my memory, making my cock twitch and my heart race with anticipation. I could feel the heat radiating from her, could smell her unique scent, and I knew that I was about to taste something that would change me forever.
“Lick it,” she commanded, her voice leaving no room for argument. “Make me cum, and maybe, just maybe, I’ll let you cum too.”
“Yes, ma’am,” was all I could say. My heart pounded in my chest as I lifted my head, my tongue flicking out to taste her. She was sweet, musky, and incredibly addictive. I began to lick her in earnest, my tongue exploring every fold, every crevice. I nibbled gently on her inner lips, pulling them slightly with my teeth, loving the way they felt in my mouth. Carrie moaned, her hips grinding against my face as she took what she wanted.
“That’s it,” she panted, her voice breathless. “Eat my pussy like a good boy. You like that, don’t you? You like tasting your sister’s cream.”
Her words spurred me on, and I redoubled my efforts, my tongue delving deeper, my suction stronger. I could taste her arousal, her cream coating my face, and it was the best thing I had ever tasted. I lapped it up, wanting more, needing more.
“Oh fuck, Mark,” she moaned. “You’re such a good little pussy eater. You love eating my pussy, don’t you? You love making me cum.”
I moaned in response, my tongue working furiously as I brought her to the brink. I could feel her getting closer, her body tensing, her breaths coming in short, sharp gasps.
“Don’t stop,” she ordered, her voice a desperate plea. “Keep going, Mark. I’m so close. I’m going to cum all over your face. I’m going to drown you in my cream.”
I could taste her arousal, feel her wetness coating my face, and it drove me wild. I wanted to make her cum more than anything. I intensified my efforts, my tongue working furiously as I brought her to the brink. I wrapped my lips around her clit and sucked on it hard while I lashed it with my tongue.
“Oh, my fucking god, Mark!” she cried out, her body convulsing as she came. Her thighs clenched hard around my head, her juices flowing freely as she rode out her orgasm. I could feel her cream coating my face, and I lapped it up, loving every second of it.
I continued to lick and suck gently as she came down from her high, her body shaking with the aftermath of her pleasure. She looked down at me, a satisfied smile on her face.
“Good boy,” she whispered, her voice soft and gentle. “You did so well. That was the best orgasm I’ve ever had.”
She slid off me, her body pressing against mine as she lay beside me, her head on my chest. I could feel her heart beating, her breath slowing as she came down from her orgasm. I wrapped my arms around her, holding her close, my cock still hard and aching with need. She idly played with my chest hair, her fingers gently tugging and twisting, sending shivers down my spine. Her touch was feather-light as she traced patterns on my skin, her nails gently scraping against my nipples, making them harden and sending jolts of pleasure straight to my cock. She continued her exploration, her fingers dancing down my stomach, dipping into my belly button, and then back up again, teasing and torturing me with her touch.
I lay there, my body on fire, my cock aching with need, as she took her time, enjoying the feel of my body under her fingers. It was pure torture, but I wouldn’t have it any other way. I loved feeling her touch, her exploration of my body, and I knew that she was enjoying it just as much as I was.
After what felt like an eternity, she finally looked up at me, a mischievous glint in her eye. “Not yet, big brother,” she said, her voice firm. “We have all day. I want to play some more.” Then she kissed me on the cheek and rolled over me, sliding off the bed to stand next to me. She gave me a smirk and reached out to grab my cock with her hand, squeezing it tight near the base.
“Time for you to scrub me clean in the shower, big brother,” she said as she pulled me off the bed and led me down the hall towards the master bathroom. She didn’t let go of my aching prick until she had started the shower and pulled me into the stall, making me stand under the cold water until it warmed up.
She just grinned at me then bit her lower lip. “You love it. Now, grab the soap and wash me from head to toe. Make sure you take your time, especially on the good parts. I want to feel your hands all over me.”
I nodded, my cock thrusting against my belly with anticipation as I lathered up my hands with soap. She turned around, presenting her back to me, and I started at her shoulders, massaging the soap into her skin, feeling her muscles relax under my touch. I moved down her back, taking my time, exploring every curve, every inch of her smooth skin. When I reached her ass, I took a moment to admire it, firm and round, before I started to wash it, my hands squeezing and kneading her cheeks.
“Mmm, that feels good,” she moaned, pushing her ass back into my hands. I spent what felt like an eternity washing her ass, my cock aching the whole time, leaking pre-cum that mixed with the water running down my body.
“Now my front,” she ordered, turning around to face me. I started at her neck, soaping it up, then moved down to her collarbone, her shoulders, and finally, her tits. I took my time, washing them thoroughly, my hands squeezing and kneading, my thumbs brushing over her hard nipples, making her gasp. I could feel her body responding to my touch, her breath coming in short gasps, her nipples hardening even more under my fingers.
“That’s it,” she panted. “Now, kneel, big brother.”
“Yes, ma’am.” I did as I was told, the tiles cold and hard against my knees.
As I knelt there, the water pounded on my back, and I started to wash her calves, then her thighs, moving upward, taking my time, building the anticipation.
“Don’t forget my pussy,” she whispered, her voice hoarse with desire.
When I finally reached her pussy, I could see how aroused she was, her outer lips slightly red and puffy, the inner lips peeking out at me. I washed her gently, my fingers exploring her folds, her clit, making her moan and buck her hips against my hand.
She stepped forward and straddled my face, her pussy hovering just above my mouth. I could smell her, that intoxicating scent that was uniquely hers, and I couldn’t wait to taste her again. She lowered herself down onto my mouth, and I started to lick and suck, my tongue delving deep into her pussy, tasting her cream, feeling her body respond to my touch. My hands reached around to grip both her firm ass cheeks, pulling her even tighter against me.
“Oh fuck, Mark,” she moaned, grinding her pussy down on my mouth. “You’re such a good boy. I’m going to cum again ... you’re going to make me see stars.”
I redoubled my efforts, my tongue working furiously, my hands still tightly gripping her ass, pulling her onto my face, wanting more, needing more. I could feel her body tensing, her breaths coming in short, sharp gasps, and I knew she was close.
“Don’t stop,” she ordered, her voice a desperate plea. “Keep going, Mark. I’m so close.”
I could taste her arousal, feel her wetness coating my face, and it drove me wild. I wanted to make her cum more than anything. I intensified my efforts, my tongue working furiously as I brought her to the brink. I looked up to make eye contact with her, desperate to see that she was happy, that I was doing a good job. But her eyes were closed, her head thrown back in ecstasy, her mouth open in a silent moan. The sight of her like that, lost in pleasure because of me, spurred me on even more. I could feel her body tensing, her breaths coming in short, sharp gasps, and I knew she was right there ... right on the edge.
