She looked shocked. Both of us Blushed with surprise. Looking with a Dead pan face I exclaimed...." follow me !"walking past other members of staff. I...told everyone we were having a one to one and we weren't to be disturbed. As her acting superior I marched her towards the office. She had a great figure as I admired her curves.I told her not to tell anyone in the work place about what she had just read out. She agreed looking seductively into my eyes. She turned around facing towards the window. It didn't take long for those little pink spots to become as hard as rocks. I moved my hand lower, circling her navel briefly and then lower yet to brush across the top of her bush. What a bush it is! Thirteen years old and she is already blessed with an adult version of a pussy mask. Soft blond hair spread across her lower abdomen, at least seven inches wide at the top and slashing down to the very edges where her legs join her torso. It was impossible, even from a few inches, to actually see. Interesting! So I roamed and started paying attention to her responses. I don’t know how long this went on but after a while her hands were no longer pushing me away but pulling my hair and her crotch was smashed into my nose. She was grinding my face, hell I thought she would bust my lip she was pushing so hard. Did she have an orgasm? I don’t have a clue all I know is after a while I noticed a change, she started pulling away and begged me to stop. ‘Please!’ she cried out and some how I. Kind of disappointed, but also understanding, I sit down and start watching her moving her fingers faster and faster from her clitoris towards her vaginal opening. Instead of two fingers she uses her full hand now and rubs with more force. She starts to moan softly which excites me even more. This is the point that I start to masturbate as well. In fact this is the first time that I jerk off in front of my wife. She gave me hand jobs, but I never did a hand job myself while being together with.
