I like the idea. Would also be possible to close the circle to the other mercs that entered with her. Make her get to see them, make her see one serving as a pony girl, or have one massive monster beast (thinking of an Oger or a centaur) try to get to have his way with her or stand guard, while she recognizes him as a former merc, with nothing of the old self left in there but pure animalistic Lust for her new body.
She's trepidatious and self-conscious, at first, at being so exposed and on display, but then she realizes how beautiful and sexy she looks and how the skimpy bra and panty set compliments her figure and its voluptuous proportions, and she falls in love with the ensemble and how they look on her, practicality gushing with giddy girlishness at how irresistibly temptatious she looks wearing them and can't wait to take them off for the right suitor -- or for that suitor to liberate them of her with unbridled lust as they ravage her femininity with abandon!!
Her expressions are perfect - great to see what's going through her mind. The tags are also a nice touch and help to further build the story here. Kudos once again.
My favorite frame (apart from how wide-open she has to keep her mouth in order to accommodate the girth of the cock she's being forced to suck) is how her eyes flash open from squinting slits as he thrusts his cock inside one more time just as he ejaculates a huge load into her gaping mouth!!!
I love how single-mindedly determined she is to make him cum -- like it's the only thing in the world she wants to do and the only thing in the world for her to do!!
