She really wanted me to experience all these lovely things in a sisterly way and I thought it really was sweet of her and a harmless little diversion.... It was a good thing I didn't have to take physical education as a senior or my new undies would have done me in for sure. Of course, I only wore the bra at her house, at least until it got cold enough for a heavy jacket. Then I wore it whenever we went out together. I suppose my longer hair helped my rather feminine image too. It turned out. "Even if that involves a smacked bottom?" to which the mother nodded.It was arranged that Harriet should have a part time job with me, two evenings a week straight after school. That meant she was kept out of trouble. Harriet would come round to my house in her school uniform. Flat black shoes, grey knee socks, a huge expanse of leg - unshaven - and a pleated grey skirt which revealed chunky thighs. White blouse, tie and blazer completed the uniform. For the first few weeks I sat at my desk. Again, I felt her hand holding my cock, as she angled it up, ready to insert it in our daughter. Marci slid down just a bit more, and I slipped inside her cunt with easy. The feeling was amazing, much tighter than I remembered. Still, I realized that I had penetrated her before, the afternoon a week ago when she had been some random whore on the other side of a glory hole. And I pushed forward, my cock stretching Marci’s lips around my invading cock.Then I hit it: The tip of my cock came. I built her passion up, slipping a finger up inside her from time to time until her hips began to thrust against my face with urgency. I crossed two fingers and carefully slid them up inside her. As I flicked and sucked her clit, I thrust my fingers deep inside her, rotating my hand with each in and out movement. It didn't take long until she began to tremble and then went rigid.Her cry filled the apartment as she came. Her hips bucked and it was all I could do to hold her as I sucked her clit.
