As her climax waned she began moaning out "oh my god ... oh my god ... oh my god ..." in time with my cock bottoming out inside her pussy. I looked once more at the clock and it showed 11:05 and I knew I was in for the long haul. Soon my never ending thrusts had her groaning hard into my shoulder and she was urging me to make her cum once more. My hand snaked in between us and quickly found her clit, making her eyes bulge in surprise. The first time I rubbed it between my thumb and forefinger she stiffened as she cried out "OH GODDDDDDDDDDDDDDDDDDDDDDD! OH FUCK ME I'M CUMMMMMMMMMMMMMMMMMMING! OH! OH! OH! OH! OH! OH! OH! OH! OH! OHFUCKYESOHGOD! YESSSS FUCK ME! FUCK ME HARDER ... HARDER ... THAT'S IT, FUCK ME AND MAKE ME YOUR BITCH!" Her cries rose in pitch and soon became inaudible as her body shook violently beneath me.
After she came back down I eased up just a bit and then gently reached under her legs and lifted them up and back until her knees were pressed to the mattress on either side of her shoulders. "Oh my god, you are in me so deep," she groaned as I resumed my slow thrusts, my cock pulling back until just my tip remained inside, then I reversed until my base pressed hard against her opening. After getting her going that way I dropped my hips an inch or so thus changing the angle of penetration. This forced my cock head to rub hard against her g-spot on each inward and outward stroke. My first stroke made Evie emit a deep and raspy groan of pleasure while I slowly picked up my pace once more.
"Oh my god, you fucking stud, I'm going to cum again! Oh my god YYYYEEESSSSSSSSSSSS!" and her vaginal muscles clamped down onto me like a ten ton press! It was difficult, but I managed to continue moving in and out of her tight passage while she cried out continuously in the beautiful agony of her climax. My sister's head was rolling side to side as she groaned and her climax slowly faded away.
Suddenly her hands came up and grabbed at my mask, trying to somehow get it off of me. "Show me your face! I have to know who it is that has fucked me so good! Tell me who you are!"
I drove my hips forward forcing my cock deeper than ever into her and making her gasp. At the same time I grabbed her hands and said as deeply as I could, "It's Halloween, bitch, that's why we wear masks!" Then I quickly pulled out and flipped her onto her hands and knees before slamming my cock forcefully back into her dripping wet pussy. After giving her two more thrusts she was no longer thinking about my identity.
