Yes

She leaned in slowly and pressed her lips against mine. It felt strange at first, kissing someone I’d known my whole life, but as the shock wore off, I melted into it. Her mouth was soft and warm, and the taste of her lipstick mixed with the memory of my own wetness drove me wild.

I kissed back harder, surprising myself with how much I wanted this. My hands roamed up her sides until they found her breasts. She moaned slightly as I squeezed them through her top, then she pulled back to yank it over her head. Her bra quickly followed, and I stared at her tits in disbelief. I couldn't believe she was actually doing this.

Taking advantage of my momentary pause, she playfully pushed me down onto the bed and straddled my waist. My clit throbbed as her body pressed against mine. “Wow,” she said breathlessly, “you're really wet.” A small "mmm" came from her throat as she climbed on top of me and began rubbing her hips against mine. She kissed me again, this time with even more urgency than before. Our tits pressed together as we kissed with increasing intensity. I could feel her nipples poking me each time they brushed against my own. Her hunger seemed insatiable as she grabbed my hands and placed them on her ass, urging me to squeeze the firm roundness beneath my fingers. She slipped a hand behind my neck, pulling me in as our tongues met. I melted into the kiss, feeling my pussy get wet again from the naughtiness of having another woman's lips on mine let alone my sister. The girlish moan that rose from deep inside me was something I couldn't control.

She pulled back slightly, just enough to look into my eyes. "You taste good," she said with a wicked smile before kissing me again. She slipped down my body, dragging kisses along my neck and between my tits. I gasped as her breath tickled my skin. She stopped when her mouth was level with my pussy, exactly where I hoped she'd end up. Her movements were deliberate, torturously slow. She let her warm breath hover against me for a moment, driving me wild with anticipation.

“Ever had a girl do this?” she teased, eyes gleaming.

I shook my head and felt every nerve ending spark to life as her tongue slid across the length of my slit. It was tentative at first, testing, like she wanted to see how I'd react. I responded with a shudder and a helpless whimper, and she took that as permission to keep going.

Her tongue dipped inside me and then back out again. "Fucking hell," I cried out as her motions became more intense. My pussy throbbed wildly as she worked her tongue in and out of me while rubbing my clit with one hand.
