Back to Present Day That had been how it was between us. She was a hard-headed, single, independent woman, and I was a hard-headed Army officer, being...paid to go to graduate school. I had always admired strong-willed women. I liked being around people who challenged me and that were feisty. I wanted someone who I could debate with and wouldn’t back down. It was fun and stimulating and, to me, sexy. In any case, I had chased her and she had met me at some restaurants and bars, always paying her. When she was all the way down on me, she looked me in the eyes and told me good job, then she asked if I heard the woman to be careful if I did not have a condom. I told my sister that I was careful, I knew I did not have a diease. My sister just smiled and took my hand and placed it on her clit as she began to fuck me. She was as pent up as I was and it only took a couple of minutes to get her to a mind blowing orgasim. She continued to ride me for another several minutes till I filled her. ”I left the implications unsaid, mostly because I wasn’t sure what they were. It was pretty obvious someone had it in for me; but what their actual goals were, and what they were willing to do to reach those goals, I wasn’t sure. All I knew so far was that the law was clearly not something that would stop them.“Well, it’s not that complicated, not really. Basically you just scratch or poke the person and it automatically administers the blood. It’s a small amount, but from Alex’s tests, it. "What are you doing?" she demanded."I have to look real close to see were I should dab..." Oh."I dipped the cotton ball in the glass, then squeezed out most of the water until I was left with a damp shrunken little piece of material. Oh what the hell, I thought. I could as well use my finger. That way I would kill two birds with one stone. First I would be able to feel the inner side of my sister's pussy and, at the same time, I would be able to remove the little stain of blood.Again my sister.
