She's ready might as well go for it.

After a few minutes of just kissing I sank to my knees in front of her again. This time my hands reached around her ass cupping the fleshy globes firmly as I leaned in inhaling her scent deeply. I then extended my tongue to lick the length of her slit, causing her entire body to tremble. This was all the impetus I needed as I fixed my mouth on her sex. my tongue lashing furiously against her clit, Catherine's hands found my head and entwining in my hair pressed my face harder against her. I lapped hungrily at her, her juices coating my mouth and chin as she began to thrash around in the throes of pleasure. It didn't take long for me to get her cumming again, her cunt pumping her passion into my mouth. Having two orgasms in such rapid succession left her almost too weak to stand and I felt her knees buckle. Catching her I lifted her back to her feet and leaned her face down over the counter. I left her there for a few minutes so she had time to regain her composure. Now that I had pleasured her it was time for me to get some relief. By this time my cock was aching from being hard for so long without release and as Catherine rested I hurriedly undid my pants and freed my aching cock, it's tip swollen and purple just aching for release. I slowly began to stroke my cock, waiting for Catherine's breathing to return to normal.

As it did I stepped up behind her and lifted her skirt up over her waist, exposing her shapely ass and now thoroughly soaked panties to the air. Her juices were glistening on her thighs as I stopped to admire her body. After a few seconds of silent appreciation I hooked my fingers in the waistband of her panties and drew them down her legs to her ankles. Bending down I lifted each foot and let her step out of them. Stepping up closer I spread her thighs a little wider with my hands then in one sudden movement sank the length of my cock into her. Catherine cried out in surprise as my cock slid fully into her, the head gently touching her cervix. I stayed there for a second, enjoying the feel of her cunt gripping my cock. Then pulling almost all the way out I forcefully thrust into her again, my momentum causing her thighs to thud against the counter. I took her forcefully and quickly, my hands gripping her hips so tight that I was sure she'd have bruises the next day. I quickly felt my limit approaching and sped up my thrusts, burying my cock fully into her as I came. It felt as though my cock would never finish spewing my seed inside her, as I ground myself against her fleshy ass. Finally though it stopped and withdrawing from her spent cunt, I leaned over, my cock resting in the crack of her ass, as I tenderly kissed her neck.
