Naughty Step-Sister's Secret Pleasure: Caught Touching Herself, Big Bro's Helping Hand

The house was quiet, or so I thought. I crept down the hall, grabbing a soda. That's when I heard it – a soft moan coming from my step-sister, Lily's, room. Curiosity, or maybe something more, got the better of me. The door was slightly ajar. Peeking inside, I saw her, sprawled on her bed, her pink pussy barely covered by her thin panties.

Her fingers danced between her legs, a small vibrator buzzing softly. Her natural tits bounced slightly with each breath. I felt a surge of… something. I knocked softly. "Lily?"

She gasped, scrambling to cover herself. "Andrew! What the hell? Get out!" Her black hair was a mess, her face flushed. She was clearly embarrassed, but also…aroused? I leaned against the doorframe. "Need some help?" I asked, a smirk playing on my lips. Her eyes widened.

"Don't be ridiculous," she mumbled, but her voice lacked conviction. I stepped closer, kneeling beside the bed. "You looked like you were enjoying yourself." I reached out, gently pushing her panties aside. "Maybe I could offer a better distraction." She hesitated for only a moment before tilting her hips upwards in invitation, revealing her piercings on her clit.

"Okay, fine," she whispered. I leaned in close, pressing my lips against her pussy. I began to lick, circling her clit with my tongue. She moaned, clutching my hair. I felt her body tremble beneath me. This bratty sis needed a lesson in pleasure. I wanted to teach her everything.

I moved upwards, teasing her with my fingertips, enjoying the feeling of her soft skin beneath my touch. Then, I sat myself on her face, a facesitting position that made her eyes widen even further. "Do you like this?" I ask, feeling her head nod enthusiastically against my mons. I felt her tongue trace my inner thigh. This was a forbidden game, a secret we'd share, a line we’d crossed and never forget. I felt her fingers trace a tattoo on my arm. This was an intense act.

The room was filled with her moans and my whispers, a symphony of forbidden pleasure. This wasn’t just helping her out; it was something…more. Something exciting, something dangerous, and something neither of us could resist.
