The sun was beginning to set as I waited in the empty classroom, the quiet interrupted only by the distant hum of the school cleaning crew. Serena Santos, my stepsister, was supposed to meet me here after school, but as usual, she was running late. I checked my phone, a message from her flashing across the screen: “Detention again, be there in 10.” No more porn family videos action, then?
I sighed, glancing at the clock. Our parents would be home in twenty minutes, and we had planned to have some fun before then. Serena was always getting into perved family trouble, sneaking around, and living on the edge. It was part of what made her so irresistible.
The door creaked open, and there she was, her hair slightly disheveled, a smirk playing on her lips. “Sorry, big bro,” she said, her voice husky. “You know how it is.”
I raised an eyebrow. “You’re late, Serena. We don’t have much time.”
She shrugged, her eyes sparkling with mischief. “Who needs time? I’ve been thinking about this all day. Let’s make it quick and dirty.”
Without warning, she pulled her shirt over her head, revealing her ample breasts. They were large and firm, her nipples hardening under my gaze. “See what you do to me?” she purred, stepping closer.
I couldn’t resist. I reached out, cupping her breasts, my thumbs brushing against her nipples. She let out a soft moan, her head tilting back slightly. “You’re already wet, aren’t you?” I murmured, my voice low.
She nodded, biting her lower lip. “Touch me, and see for yourself.”
I slipped my hand down her pants, feeling the wetness on her panties. She was dripping, her pussy already slick and ready. I pulled her closer, my lips finding hers in a hungry kiss. Our tongues clashed, exploring each other’s mouths as our hands roamed over each other’s bodies.
Serena broke the kiss, her breath ragged. “I want you,” she whispered, her eyes locked onto mine. “I want you to fuck me hard and fast like in the porn family videos.”
She sank to her knees, her eyes never leaving mine as she unzipped my pants. My big cock sprang free, hard and ready. She licked her lips, her eyes widening slightly at the sight of it. “Damn, big bro,” she said, her voice filled with awe. “You’re packing.”
She nodded, her tongue darting out to lick the tip of my cock. “Mmm, I love it,” she murmured, before taking me into her mouth.
The sensation was incredible. Her mouth was hot and wet, her tongue swirling around my shaft as she took me deeper. I groaned, my hips bucking slightly as she deepthroated me. She looked up at me, her eyes watering slightly, a satisfied smile on her face.
“Fuck, Serena,” I groaned, my cock throbbing in her mouth. “That feels so good.”
She pulled back, her breath coming in ragged gasps. “I want to feel you inside me,” she said, her voice barely a whisper.
I helped her to her feet, my hands exploring her body as I turned her around. She bent over slightly, her ass sticking out invitingly. I ran my hands over her curves, my cock throbbing with anticipation.
“You’re so fucking sexy, Serena,” I murmured, my voice filled with desire.
She looked back at me, her eyes filled with lust. “Fuck me, big bro. Make me yours.”
I slapped her ass lightly, her skin jiggling slightly under the impact. She moaned, her pussy clenching in anticipation. I rubbed my cock against her entrance, feeling her wetness coating my shaft.
“Ready?” I asked, my voice a low growl.
She nodded, her breath coming in short gasps. “Yes, fuck me. Please.”
I thrust into her, my cock filling her completely. She let out a loud moan, her body trembling slightly at the sensation. I gripped her hips, my fingers digging into her soft flesh as I began to move.
“God, you feel so good,” I groaned, my hips moving in a steady rhythm.
Serena met my thrusts, stepsister and stepbrother bodies moving in sync. “Harder,” she gasped, her voice filled with desire. “Fuck me harder, big bro.”
I obliged, my hips slamming into hers as I fucked her harder and faster. The room filled with the sound of our bodies coming together, our moans and gasps echoing through the empty classroom.
I reached around, my fingers finding her clit. I began to rub it in time with my thrusts, my cock hitting her G-spot with every movement. She let out a loud cry, her body tensing as she came, her pussy clenching around my cock.
“Fuck, Serena,” I groaned, my own orgasm building. “You’re so fucking tight.”
She moaned, her body still trembling from her orgasm. “Cum inside me, big bro,” she gasped. “I want to feel you cum inside me.”
Her words sent me over the edge. I came hard, my cock throbbing as I filled her with my cum. She let out another loud moan, her body milking my cock as I came.
We stayed like that for a moment, our bodies pressed together, our breaths coming in ragged gasps. Eventually, we pulled apart, our bodies slick with sweat.
Serena grinned at me, her eyes filled with satisfaction. “That porn family videos action was amazing, big bro,” she said, her voice filled with warmth.
I smiled back at her, my chest still heaving. “It sure was, little sister. But we better get going, our parents will be home soon.”
She nodded, pulling her clothes back on. “Yeah, we don’t want to get caught,” she said, her voice filled with a mischievous glint. “But maybe next time, we can take our time.”
I laughed, pulling on my own clothes. “Maybe next time,” I agreed, my eyes filled with anticipation.
As we left the classroom, hand in hand, I knew that this was just the beginning of our secret adventures. Serena was a wild one, and I couldn’t wait to see what else she had in store for me.
