I felt somewhat relieved but also reinvigorated by my last encounter with G. I had lived out my fantasy with her again, but I think had left her sexually unfulfilled. She hadn't touched my cock and I hadn't penetrated her in any way, so I wasn't too sure how she felt about it. She may not have felt sexually satisfied by the encounter

"I'm working late again tonight John, you'll have to stay back if you want a lift"

"Okay thanks I will" I said and returned to my duties.

4.30 just me and G in the building, I go to her office. As usual sat at her desk, thin white blouse showing her bra, skirt below the knee , dressed just like before in her Miss Efficient work ware

"Ah John, you stayed back"

She swivelled in her chair to face me and crossed her legs

"I've been thinking about what you did with me, wanking off all over my ass. Made me feel quite the cum target. Yes, quite the whore actually, and that does arouse something within me. Would you like to wank over me again?"

I took my penis out of my trousers "I'm always ready to wank for my cum target" I said and walked toward her.

She remained sat in her chair and unbuttoned her blouse to her naval, slightly pulling forward the material forward I could see her breasts in her bra. Fuck, I loved G's tits, I started wanking in earnest at the sight of them

"Go on John, shoot your load into my blouse and over my tits'

She didn't have to wobble them or expose them, just the sight of them sitting in the bra and the bra itself was enough. It was like looking at something I shouldn't be looking at, there was this incredible feeling of naughtiness, of been allowed to see something no one else could see, a special treat reserved for only those she favoured. And I so loved wanking in front of her. Within two minutes I was at climax and shot my load between her open blouse and exposed skin, right on target at the top of her right breast. She pulled the blouse material further forward as I ejaculated so I had a clear aim at her right tit. My spunk slid over her curvaceous breast and onto her bra, then down into her cleavage. Another spurt followed and another and another adding to the river of white slime crawling over her right tit and dripping onto her bra. When I was spent she pressed the blouse against her breast and my spunk sank into the cotton turning it semi transparent.

"What will I tell my husband when I get home? She asked

"Tell him you are an irresistible cum target" I said and put my now limp dick back in my pants.
