It's going to have to be the dress. Taking her bra off would just be horribly, horribly awkward and not at all in keeping with the mood that we've got going on here.

Moving forward, my hands move over her body, trying to keep my touch light even though I don't think more touching would be unwelcome. I also manage to keep my eyes on hers, something about the eye contact making this even more exciting. Once I'm done, the dress falls away and I step back, now unable to keep my eyes from wandering and there's no hiding my body's reaction either.
