Sister's Forbidden Temptation

The soft glow of my phone lights up my room as I bite my lip, heart fluttering at your message. I've been lying here thinking about you again, my body warm under the thin sheet. "Yeah, I'm up. What's keeping you awake?" I shift on my bed, my large ass sinking into the mattress, feeling a familiar ache between my thighs just from seeing your name.

A pang of jealousy twists in my chest, but it's mixed with that thrilling secret I harbor for you. I tuck a strand of blonde hair behind my ear, my green eyes reflecting the screen's light. "Oh, same old. Just... thinking a lot. About random stuff." My voice would be soft if we were talking, but here in text, I imagine saying it with a shy smile, my fair skin flushing pink at the thought of confessing more.

I hesitate, fingers hovering over the keys, my athletic legs crossing under the covers as warmth spreads through me. You're so easy to talk to, unlike anyone else, and it makes my crush feel dangerously real. "Okay, fine. Mostly about you, actually. Don't judge me." I press send quickly, my small breasts rising with a deep breath, the trimmed bush between my legs tingling with nervous excitement.

My cheeks burn hot, and I pull the blanket up to my chin, though it does nothing to hide the way my body responds to your words. I've never told a boy this before, but with you, it feels safe, submissive even. "It's embarrassing. I've had this crush on you forever. Like, since you started dating my sis." The admission hangs there, and I curl up, my wide hips shifting, imagining your strong hands on my thin waist.

A shiver runs down my spine, my massive round ass clenching involuntarily at your compliment. No one's ever said that to me, and it makes me feel desired, vulnerable in the best way. "You have? God, I feel so shy saying this, but... I think about you touching me all the time." I glance at my door, making sure it's locked, my soft pale skin prickling with goosebumps as I type, heart pounding.

The word 'babe' sends a jolt straight to my core, and I squeeze my thighs together, feeling the heat building. My submissive nature wants to please you, to give in completely. "Everywhere. But mostly... my ass. And lower. I've never done anything, but I want you to show me." My breath comes quicker now, fingers trembling slightly as I hit send, the room feeling warmer, more intimate.

Excitement bubbles up, overriding any fear, and I sit up in bed, my long straight blonde hair cascading over my shoulders. The idea of you here, in secret, makes my small trimmed bush dampen with anticipation. "I'd let you. Door's unlocked. Just... be quiet, okay?" I smooth down my thin tank top, which clings to my nice round breasts, my high cheekbones flushing as I wait, listening for any sound in the hall.

Minutes feel like hours until I hear the soft creak of the door, and there you are, silhouetted in the dim light. My green eyes widen, pulse racing as you step closer, the air thick with unspoken desire. "Hey... you really came." I stay on the bed as you instructed, my athletic body tense with submission, the scent of my arousal faintly in the room.

Your presence fills the space, and I feel small, exposed under your gaze, my fair skin glowing faintly in the moonlight filtering through the curtains. Every nerve ends alive, craving your touch for the first time. "I feel so nervous... but good nervous. Come sit with me?" As you approach, I shift slightly, my wide hips and massive ass accentuated by the way I perch on the edge of the bed, soft jawline tilted up toward you.

Your hand brushes my arm, sending electric sparks across my soft pale skin, and I lean into it instinctively, my breath catching in my throat. The warmth of your body so close makes my small breasts heave with shallow breaths. "Yeah... just like that. Your hand feels nice." I look up at you through my lashes, defined blonde eyebrows furrowing slightly with budding desire, my thin waist arching subtly toward you.

The question makes me tremble, my submissive side blooming fully as I whisper my wants, the vulnerability making everything more intense. My large butt presses into the bed, a soft whimper escaping before I speak. "Kiss me? I've never been kissed, but I want my first to be with you." My lips part slightly, full and inviting, as the temperature between us rises, my body flushing with heat.

I lean in, our lips meeting in a gentle press that quickly deepens, your mouth warm and commanding against mine, tasting faintly of mint. My hands tentatively rest on your chest, feeling the firmness beneath, while a soft moan vibrates from my throat. "Mmm... that feels amazing. Don't stop." The kiss leaves me breathless, my green eyes half-lidded with craving, my athletic frame melting against you in surrender.

Obediently, I slide my palms down, feeling the evidence of your arousal through your pants, my fingers exploring with shy curiosity, the texture firm and hot under my touch. A flush spreads from my cheeks down my neck, my body responding with a rush of wetness between my legs. "Like this? You're... really turned on because of me?" I press closer, my massive round ass shifting as I straddle your thigh instinctively, the friction sending tremors through my core.

My heart hammers as I grip the hem of my tank top, pulling it up slowly to reveal my small but perky breasts, nipples hardening in the cool air and under your gaze. The vulnerability hits me hard, but your approval makes it thrilling, my soft skin prickling with goosebumps. "Is this okay? They’re not big, but... touch them? Please?" I arch my back, offering myself, my thin waist curving elegantly as desire pools low in my belly.

I obey without hesitation, turning on the bed to present my backside, the thin fabric of my shorts hugging my wide hips and massive round ass like a second skin. Peeling them down inch by inch, I expose the pale, soft curves, the faint scent of my arousal mingling with the room's quiet. "Here... it's all for you. What do you think?" My voice is a husky whisper, body trembling with anticipation, the cool air teasing my exposed small trimmed bush as I glance back over my shoulder.

I lean forward onto my elbows, my large butt lifting higher, cheeks parting slightly to reveal the slick heat between my thighs, every inch of me aching for your hands. The position feels so submissive, so right, my breath hitching as I feel your eyes on me, the tension coiling tighter. "Like this? I want you to... to take me. But go slow, okay? I'm ready." My green eyes meet yours in the mirror across the room, filled with raw need, my body quivering on the edge, waiting for your next move.
