She squeezed hard as she opened her mouth and took my engorged head in to her hot, wet mouth and clamped down on to it, sucking ferociously and making sure I had to bite my lip to stop the moans of pleasure being heard outside of our cubicle. I looked down as her head went back and forth on my ever expanding cock and she went deeper and deeper down my shaft.
I don't know whether she had done it on purpose or in her bobbing it had loosened but a couple of buttons on her blouse had become undone and I could see substantial domes of her breasts, packed tightly in to her black, lacy edged bra, heaving as she sucked harder. She looked up and our eyes met and while mine were full of a pleasured but strained look, hers smiled at me knowing her prophecy would soon become true.
She dragged her teeth up the length of my thick, veiny shaft back to my head where once again she sucked with a savagely I wanted to scream out but she knew when to stop short of that and instead I felt the tip of her tongue wrap around my head like a Boa about to suffocate it's pray and squeeze life force out of it. She was in for the final kill as I felt the end of her tongue inside my small hole, stretching it wide, opening it up for me. I knew only two things at this point.
Cumming was imminent and I could not allow her to spill a drop or leave any evidence across her face. As she sucked once more sensing my impending orgasm. I placed my hand at the back of her head, stifling her ability to move anywhere but downwards, held captive, as I felt my balls explode.
I let out a muffled groan as my first jet of thick cum hit the back of her mouth and she eagerly swallowed it. I needn't have worried about her spilling any of my seed as each load I shot was easily despatched in to her stomach and as my breathing eased and my balls emptied, I removed my hand and allowed her to come up for air.
Her tongue flicked around my head ensuring all remnants of cum were cleaned up and she even managed to catch the last watery drips that emerged from my tip. Once she was sure ever drop had gone she rose to her feet. Once again she faced me, this time with a board grin across her face and as she buttoned up her blouse.
