You know me well, Snailman; a bare tummy HDS will always appreciate! Karin's got a devious look goin' there but Sakura's "barely held in" is the real star. As you noted elsewhere, "one of those pics where you just wanna lazily drift your fingernails over a bare tummy"; methinks Karin is doing just that and Sakura is just about to lose control. That method is one of my favorites, where you can lazily stroke across and bring someone right to the edge of outright laughter. HDS certainly approves heartily. :happy:
Coincidently (or not, as it may be), Sakura is actually my favorite SF gal, quite probably because of the exposure her outfit afforded her.
