A brutal fingering

With my ass in the air, suddenly Alice gave it a good slap. "Ah!" I cried out, not expecting the sensation.

"Shh!" Alice commanded. "Do you want to wake up your roommates?"

I rolled my eyes. "Like you're one to talk," I shot back. "Slap me again like that and they'll definitely wake up."

*slap* she spanked me again for talking back. I just wiggled my ass in response. Alice must have liked that, because then she suddenly placed her fingers right over my soaking pussy. I was tingling from the very slight stimulation. I'm sure Alice could feel it too, because she just ran her fingers up and down on my opening. Never daring to go any further.

"Alice" I exhaled.

"Yes, Christy?" Alice replied innocently.

"Please," I moaned, while she continued to tease me.

"Hmm?" she pondered. "Well, if you insist." And suddenly she thrust her fingers inside of me.

"FUCK!" I gasped, unable to keep my surprise inside. Luckily I had my face buried in my pillow, or my roommates and maybe the whole apartment would have woken up.

"MMHHM!" My moans kept going, as Alice kept pumping into me. I was getting dizzy. Her fingers were so slick they had no trouble penetrating me. I couldn't even count how many fingers it was, but she pressed against me hard and made sure to push as deep as her hand could go.

I was in heaven. "Wow, Christy!" Alice complemented, "Who knew you looked so sexy from back here." I couldn't muster a response to that. My hips started moving on their own, thrusting back into Alice's hand to make each pump harder, more forceful.

It hadn't even been a minute yet but I could feel myself rapidly approaching an orgasm. My breathing quickened. "Alice, Alice" I repeated. "Oh fuck, Alice."
