I walked into her room without knocking, the way I always did. Mia was on her bed in just a tank top and panties, scrolling on her phone, legs spread like she didn’t give a fuck who saw. She looked up, annoyed, but didn’t cover up.
“Get out, perv,” she said.
I shut the door behind me. “You told me you’ve never had cock. Not once.
All those girls, but nothing real between your legs.”
She rolled her eyes. “Because I’m a lesbian, dumbass. I don’t want dick.”
I stepped closer. My cock was already hard, pushing against my jeans. “You’re my sister. I don’t care who you fuck. I’m giving you your first one anyway.”
Mia stared at the bulge. Her tongue wet her bottom lip before she caught herself. “You’re fucking sick.”
“Yeah. And you’re wet.” I grabbed her ankle and yanked her to the edge of the bed. She didn’t fight hard. Her panties were soaked through when I hooked a finger under the crotch and pulled them aside. Slick, pink, and shaved. I rubbed two fingers through her folds and she hissed.
“Stop,” she said, but her hips tilted toward my hand.
I unzipped, pulled my cock out, thick and veined, the head already leaking. I slapped it against her clit a few times, hard enough to make her jolt. “First cock. Mine. Right here.”
She glared but didn’t close her legs. I lined up and pushed the head inside. Tight. Hot. She gasped, eyes wide.
“Fuck, it’s big,” she breathed.
I drove in slow, inch by inch, watching her pussy stretch around me. She was dripping down my shaft by the time I bottomed out. I stayed there, grinding my hips so my cock rubbed every spot inside her.
Mia’s hands fisted the sheets. “This doesn’t mean I’m not a lesbian.”
“Doesn’t matter,” I said, pulling out and slamming back in. “You’re taking your brother’s cock like a good little slut.”
I fucked her steady and deep, the wet sound of her cunt filling the room. Every thrust made her tits bounce under the tank top. I reached up, yanked it down, and sucked a nipple hard while I pounded her. She moaned, loud and filthy, the sound she never made with her girlfriends.
“Harder,” she finally said. “Fuck me harder, you asshole.”
I flipped her onto her stomach, yanked her hips up, and drove back in. Her ass bounced with every slap of my hips. I reached under and rubbed her clit fast and rough. She came hard, pussy clamping down, soaking my balls. I didn’t stop. I fucked her through it, then pulled out and flipped her again so I could watch her face when I came.
I shoved back inside, deep, and unloaded. Thick ropes of cum flooded her cunt while she shook under me. When I pulled out, my load leaked out of her swollen pussy in a messy white drip.
Mia lay there panting, legs still open. “That was… fuck.”
I wiped my cock on her thigh. “First cock. You’ll want it again.”
She didn’t argue. She just reached down, scooped some of my cum onto her fingers, and sucked them clean.
