Unexpected Sibling Spark

I pushed open the door to April's room without knocking, expecting to borrow her charger like always. There she was, sprawled on her bed in nothing but a lacy black bra and matching panties, one leg bent, phone in hand. Her skin glowed under the afternoon light, curves on full display. She looked up, unfazed, a smirk playing on her lips.

"Well, well, little brother. Ever heard of knocking? Or are you just that eager to see me like this?" April's voice was sharp, teasing, with that signature wit that always kept me on my toes. She didn't cover up; instead, she stretched, arching her back slightly, making her breasts strain against the bra. I froze in the doorway, heat rushing through me. "Sorry, I... charger. Didn't think you'd be... like that."

She laughed, low and throaty. "Like what? Half-naked and horny on a lazy afternoon? Get in here and close the door before Mom hears us. Or are you too shocked to move?" Her eyes flicked down to my jeans, where things were already stirring. I stepped inside, shutting the door, pulse racing. The tension crackled instantly—years of playful banter now laced with something electric.

"Horny? You?" I shot back, trying to match her wit. "Thought you were too busy bossing everyone around to get wet." April sat up, crossing her arms under her chest, pushing it up invitingly. "Oh, I'm wet alright. And if you're going to stare, you might as well do something about it. Come here." Her tone was commanding, strong—she wasn't submitting; she was inviting me into her game.

I crossed the room, sitting on the edge of the bed. "This is crazy, April. We're siblings." She rolled her eyes, leaning closer, her breath warm on my neck. "Siblings who clearly want each other. Feel how hard you are already? Don't pretend." Her hand brushed my thigh, bold and unapologetic. Dialogue flowed like sparks: "What if I want that cock of yours?" she whispered. "Think you can handle my pussy without chickening out?"

The air thickened with desire. I pulled her into a kiss, hands roaming her smooth skin. She responded fiercely, tongue dueling mine, not yielding but matching every move. "Mmm, that's better," she murmured between kisses. "Now lose the clothes. I want to see you hard and ready." I stripped, my cock springing free, throbbing. April's eyes gleamed with approval as she shed her bra, revealing perky breasts, nipples hard. She hooked her thumbs in her panties, sliding them down slowly, exposing her dripping pussy.

"Like what you see?" she teased, spreading her legs slightly. "My ass is pretty nice too, but let's start with this." She reached for my cock, stroking it firmly, her grip confident. "God, it's so hard. Bet you've thought about this." I groaned, fingers finding her wet folds, sliding inside her pussy. She was soaked, panting already. "Fuck, April, you're dripping." We traded barbs even as heat built: "Shut up and eat me," she demanded with a grin. I obliged, tongue lapping at her clit while she gripped my hair.

Soon she pushed me back, straddling me. "My turn for control." April lowered onto my cock, taking me deep into her tight, wet pussy. We moved together, her riding with strong, rhythmic thrusts, ass bouncing. "Yes, fuck me harder," she gasped, sweating, her body glistening. I thrust up, hands on her hips, both of us panting. The sex intensified—her blowjob earlier had been teasing, lips wrapped around my cock until I nearly came, but she stopped, smirking. "Not yet."

Now, climax hit as she clenched around me, cumming with a cry, her pussy pulsing. I followed, exploding inside her, cum filling her as we both shook, sweating and spent. April collapsed beside me, witty even then: "Not bad for a first time, bro. But next chapter might get wilder."

She traced a finger down my chest, eyes sparkling with promise for what came next.
