what guy in his right mind (at least here) wouldn't want to see Sakura just a little bit more Raincoat? That is an easy question and I can predict the outcome right now.
If our dear Sakura does decide to do anal scene I would suggest first getting comfortable with it off camera with someone that cares (and no I don't mean myself, although ....), someone that she might actually enjoy it with and ease into it, instead of jumping in head (or ass in this case) first and not convey the right mood and passion of the scene.
Car is a good motivation but is it strong enough to make something that makes you uncomfortable seem hot?
While the female talent is the main course in a porn scene let’s not forget that anything well done is a team effort. The camera angle, the editing, the quality of the reproduction, the x-factor of how the male talent performs, props, scenery all play into my evaluation of what is good. After thinking about what my favorite, multiple viewed scenes were I came to the conclusion that anal or not was not even a consideration. I would rather watch a high resolution well shot scene of most any mainstream porn star than an all-anal, gangbang of my favorite with crappy camera angles. The cameraman may be the most under appreciated man in porn.
