Something had to change. Much as I enjoyed G and how are sex adventures had progressed, I realized I didn't really want to be so dominated by her. Yes, being naked in front of her while she was dressed was great and the core of what I had come to realize was my fetish, but it didn't really include getting on my hands and knees and drinking her pee, okay as a one off, not as an ongoing thing.

I mentioned my thoughts to G in the car on the way into work, explained as best I could.

"John, if it doesn't work for you, if I've gone to far, that's fine, I understand. This is about both us us having a good time, so next time we meet why don't you take the lead, tell me what you want. If you don't say I won't know"

This was great. All I had to do now was work out exactly what it was I wanted to do with her for me. I came to the conclusion it was nothing. There was something about just been naked and wanking off in front of the clothed older woman that just worked for me. I sent G a text

"Hi G, next time we meet straight CFNM, lets see what happens from there"

"An anticpoated pleasure :-)" was her response

The following day at work, G called me into the office

"You don't have to wait til hubby is out for this" she said "How about after work today? I'll just tell him I have to work late"

My legs went to jelly, my heart raced

"Er yes sure" I stumbled

The afternoon couldn't go quick enough and by 4.30 everyone was out of the building. I went into her office and closed the door behind me. There she sat in her usual work blazer, white blouse, dark blue skirt just below the knee, tan tights (I assume) and flat black shoes. There was something about getting naked in front of her in her work clothes that really added an edge for me

"Just a minute" she said and pulled a red lipstick from her desk drawer. I watched her apply it and check herself in the compact mirro "Now John, where would you like to start"

"I'd just like you to sit there G"

I took all my clothes off and stood naked in front of her, my erection unashamedly on full display.

I stepped over to where she was sitting and started to rub my prick against her left arm, then across the blazer over her breast. I opened the blazer and put my dick inside so it was next to her blouse. Oh that was nice sensation, feeling her stiff lacy bra under her silky blouse on dick.

"Oh G this is so nice" I said

Then I took hold of my penis and brought it up to her face, then rubbed it on her along cheeks.

"Stand up" I said "Step away from the chair so I can move all around you"

She rose from the chair and pushed it away. I rubbed my love pole against her left thigh as I caressed her large ass with my right hand through her skirt and touched the top of her thigh with my left. I slowly thrust my hips backwards and forwards on her skirt, squeezing her fleshy body as I did so, then slowly walked behind her keeping my erection n contact with her all the time and did the same on her right leg. Next I was straight behind her, I was drawn to her magnificent ass.

"Lean forward onto the chair back" I sad

She dutifully did so, pushing out her gorgeous skirt covered ass out and slightly parting her legs. I ran my cock it and up and down her big buttocks. I was sooo enjoying this. I grabbed her hips as I stroked my cock over her ass

"Your big ass is fucking mind blowing" I said

She looked over her shoulder and smiled

I decided this was it, I stated to wank looking at that beautiful big round ass. In no time at all I was at orgasm shooting my load with great satisfaction all over G's skirt. I let out a groan as my balls emptied and I watched my seamen hit the dark blue material and slowly drip down or be absorbed by the material.

After taking time to fully take in the awe inspiring sight of my triumphal load strewn across her mind blowing ass, I said

"There's something about you G that just makes me want to cover you in spunk"

I put my clothes on and walked out of the office.
