You think you might be able to come to an arrangement

How are you exactly meant to refuse this. Your blood has certainly drained to one part of your body and as it has your mind become increasingly one tracked.

"Well Gisele I think we can come to some sort of arrangement," she seems relieved as you say this but still nervous unsure where this might head. "how about you come round here..." you say before trailing off as she already nods slightly and makes her way round your desk towards you slowly. Her beautiful tanned breasts still exposed to your increasingly hungry gaze.
By the time she's come around to you you've swiveled your chair correspondingly so she's stood just in front of you. You're still seated so she's stood in front of you causing you to look up slightly but only marginally as your eyes are now entirely fixed on her tits.
Without really thinking or saying anything you reach out with your hands to her breasts. She flinches slightly as your cool, in comparison, finger tips make contact with her warm skin. You notice her look away slightly, her cheeks flushing dark once more, and her bottom lip clamped between her teeth firmly. But she says nothing, scarcely even breathing as you take her breasts in your palms.
You begin a tentative assement of them, relishing each centremeter of her tits. Your fingers pushing lightly into her soft warm skin. They're without a doubt natural and contain that delectable soft yet firmness that real tits have. Due to their size despite the changes from motherhood they've remained relatively pert and firm which you increasingly grow to enjoy as your palms and fingers assess over each.
After a few long moments of this you find your thumbs making their way almost naturally to her dark nipples. Stroking across them you're surprised by how hard they are already. Presumably due to the coolness of your hands in comparison but also the not so gentle stimulation you had been providing her body thus far. You'd like to say it's also due to arousal but that would seem unfortunately unlikely as a quick glance to her face highlights her only increasing embarrassment at her situation with her eyes now covered with a slight wet sheen of tears being held back.
Having toyed her nipples to further firmness and explored her great breasts, the piercing being a particular interest as you notice it takes little to excite and her body reacts strongly to even the lightest of touches to it, you decide you wish to progress. You haven't after all come to any kind of agreement.
