After the initial shock of seeing her nakedness, I snapped back to reality and started to soothe her. I explained that since the tissue was not soaked in blood the cut could not be too bad. She seemed to be a little more optimistic about her situation. I told her I needed to examine the wound up close. With that she leaned back and spread he legs open. I knelt down in front of the counter, not only just to get a better look at the cut but to hide the massive erection trying to escape my pants. Since I still had my uniform pants on I had a pair of latex gloves at the ready. As soon as I pulled them out Tina said they weren't really necessary since we were family. I tossed them aside and leaned in for a better look.
Knowing this was my sister made this situation delicate. Normally I would dive in and take charge of a situation. Being the ranking member on my crew I was usually the lead on a call. But today I had no back-up; no partner to help treat the patient. With shaking hands I gently reached up and removed the tape from her labia. The cut was about a centimeter long and barely visible. I am sure at the time of the injury the cut seemed humongous and life threatening. I looked up at my sister and could see the fear in her eyes. Having comforted her over the years I was at a loss over what to say to her. The cut was no worse then a paper cut and would heal up very quickly with no scar. But to my sister this was a debilitating injury that could linger for a long time.
With all the potential words of comfort rolling around in my mind I couldn't believe what I did next. I was mesmerized by the sight of these two luscious lips just inches away from my face. Perfectly symmetrical. Freshly shaven. Without thinking I leaned in and gently kissed the cut. I don't know why I did this. But for whatever reason I felt it necessary to kiss her "boo boo". As I leaned back reality hit and I realized what I had just done. I had just kissed my sister's pussy. I could feel my face getting flush and I was afraid to look up. Just as I thought I had done the worst thing imaginable, my sister reached down and lifted my chin. "That was so thoughtful," she said, "would you kiss it again?" I was dumbfounded. Instead of being called a pervert or worse, Tina actually liked what I had done. And before either one of use could come to our senses, I leaned in and kissed her "boo boo" again, this time taking my time to let my lips linger on her lips. The scent of her jasmine body wash was being replaced with the musk of her sex. I could tell she was becoming excited. As I gently kept kissing her pussy, she reached down and held my head close to her body. My hands had gone from the edge of the counter to the roundness of her ass. I worked my kisses up her taught stomach and found my way to her breasts. I sucked her nipples feverously and took time to give them equal attention. As she became more excited, Tina gently pushed my head back down to her dripping pussy. I lapped up her juices having never tasted anything like it. I continued kissing her pussy lips as she crept closer to orgasm. My gentle kisses morphed into suckling on her little cherry clit and probing the depths of her lips. I could feel her heat increasing as her lips became engorged with blood. Her labored breathing changed into low moans as she moved towards her climax. With a few final licks to her clit her body tensed and she screamed out in ecstasy.
Tina grabbed my chin and lifted me up to meet her in an embrace. Before I knew it we had moved to her bedroom and she was tearing my clothes off. She pushed me onto the bed and straddled my legs. She leaned over and gave my rock-hard cock the same attention to which I had given her pussy. As she licked and sucked I laid back and tried to last a long as I could. My sister evidently had practiced sucking cock and was very good. I could feel my balls tighten as she engulfed my entire cock bringing me ever closer to blowing my load. She looked up and shook her head indicating she didn't want me to cum yet. Believe me it was all I could do to hold back the tide of semen. With one last lick she released my cock from her mouth and started kissing her way up my body. By the time she reached my neck she had managed to position her pussy lips over my cock. She whispered in my ear that she had always dreamed of fucking a man in uniform. And with that she plunged down on my cock taking it all the way to the hilt. Our lips met in passionate kisses as she rode me. Having been at the edge all the while she sucked me, I knew I wouldn't last long in the depths of her tight pussy and I told her the same. With that she increased the intensity of her gyrations and whispered in my ear "cum with me." That is all it took to push me over the edge. I could feel my balls empty my seed deep inside my sister's love hole just as she reached her climax. Her pussy tightened up and milked every last drop of cum out of my cock and with that she collapsed on top of my chest.
Having spent the past hour fucking, Tina was already going to be late for work. She called her boss and told him she had sustained an injury and was being "treated" and would be unable to come in that day. As she hung up the phone I already had my tongue back in her pussy and spent the rest of the day "healing" my sister.
