I never expected my little sister to become so seductive, but there she was, naked and waiting for me during our late night jerk off session.As I grabbed my cock, she licked her lips and flaunted her ass, whispering sweet nothings into my ear.I couldnt take my eyes off her curvy figure as she gracefully straddled me, her pussy dripping with arousal.Her dark hair cascaded down her back like a waterfall, accentuating her slender frame.As we both got lost in the moment, her hands slid down to my abs and she playfully tugged on them, causing my cock to twitch with every touch.She leaned in, kissing me deeply while her tits bounced in my face.Her nipples were hard and erect, poking out against her silky bra.I couldnt help but grab one in my mouth, feeling the hard peak between my teeth.She moaned in pleasure as I bit down harder, wanting to take every inch of her into me.She began to slide up and down my cock, her tight pussy gripping me with every movement.She arched her back, pushing her tits towards my face, wanting to give me a better view.With each thrust, her clit swelled and pulsed, sending waves of pleasure throughout her body.I couldnt take it anymore, and pushed her off me, rolling over onto my back.As I spread my legs apart, I watched as she slid down to straddle my face, her pussy hovering just above my nose.I licked her from top to bottom, savoring every taste and texture.Her clit was now red and swollen, begging for release.I sucked on it harder, feeling her quiver and scream with pleasure.I couldnt believe how easily she succumbed to my desire.She was in lust just like I was.As I held her tits, she squirmed and bucked, trying to stay still on top of me.But I couldnt resist pulling her closer, my mouth latched onto hers, stealing kisses as she grinded her hips against my face.We both fell into a rhythm, our bodies working together in perfect harmony.It felt like hours before finally, she screamed out cum! and exploded onto my face.I let her come all over myself, reveling in her wetness.I then released my own load all over her chest, marking her as mine.I couldnt believe what had just happened, my little sister seducing me during a late night jerk off session.But there was no denying the intense pleasure and connection we both felt.It was a experience that I would never forget, and something that my little sister and I would continue to explore in the future.
