She asked me to stop. I stopped, I took my cock out. it was covered in specks of blood here and there. I knew she was still in pain. I decided to take...her ass; I held her bum and rubbed the cock on her ass. She said “no no no, not there” I didn’t say a word. I pushed the tip of the cock in her ass. Her ass closed tighter. I put my thumbs on her ass cheeks and spread it wider. It took about 10 mins for the head to get in. she was loving the pain. she wanted me to push the rest in one stoke. I. And I was sure it was out of the blue because other than Hans asking about her, I hadn’t even had the first thought of her as anything other than a friend. The girl who had flirted at the dance club hadn’t seemed overly serious, and I didn’t get the idea that any of the girls had felt the ‘vibe’.We reached Vondelpark and I quickly scouted for a quiet, relatively private place to sit. I saw a spot under some large trees that was grassy and semi-secluded, and led Karla there. I sat down and she. Without even waiting for my answer she came and sat down on my lap. The distance between me and the table was short and she had to push herself to find accommodation. Her short skirt rode up her thighs in the process. I tried to act normal but after a while she began to move around a bit. My penis had expressed its delight long back and it was not pressed against her buttocks. As I was solving a problem in Physics she suddenly bent forward raising her body a little and in the same motion freed. Her research team was having a very good day, after years of work, it appeared her brainchild–a drug to stimulate female arousal, long sought by doctors and patients alike–was ready for the FDA’s human-trials phase. As long as the big-wigs gave the green light to trials, Stimulex would be on its way to market within the year. She knew, though the board almost certainly didn’t, that the human trials were a formality. Her team already knew beyond doubt that it worked, and far better than anyone.
