Troy's cock was still firmly inside me and hard as only a sixteen-year old guy can be as we watched his mother pull her bra off her large breasts whic...h must have been DD's crowned with large brown nipples which stood out from her breasts. They didn't sag much, just a little, and we just stared at her as she stood there in front of me and her son, who, I am guessing, has never seen his mother naked before.I couldn't help but wonder what the hell she was thinking about or thinking about doing.. Those long slim legs and round firm tits. She pulled on a pair of panties and then went to make a cup of tea; god doesn't that girl ever get dressed. She just had the most perfect tits I had ever had my hands on although I've no idea what size they are and Liz probably doesn't either. She doesn't ever wear a bra and I suspect that doesn't even own one. The last time she wore one was at school and that was a 32A but she says she has grown a bit since then."We doing anything today?" she asked. “But I do want you. How about if I pick you up at six in the parking lot out back.”Oh my God! He was too damn sexy to refuse."Six,” I said breathlessly.“Six,” he replied, taking a step backwards. I watched as he slipped out of the Day Room. I looked at the clock. It was three thirty-one. Six o’clock could not come fast enough.The Lieutenant was waiting in his car in the parking lot when I stepped outside the back door of the platoon headquarters and looked around. He lightly tapped on the horn. I've never done any of this either, but I'll give it a shot.” I placed my right hand on her pussy and began to slowly rub what I believed to be the clit. She seemed to be responding so I continued. Her breathing was steadily increasing. Deeper and faster. She moaned slightly and I decided to slide two fingers into her. I was amazed at the amount of liquid that was drenching her pussy and inner thighs. My fingers seemed to be exciting her extremely so I sped up a little and she moaned slightly..
