Honestly,
I have to admit I'm a bit of a panty fan, i find myself taking a glimpse up a girls skirt if the oppertunity is there. Personally I find myself very turned on by a girl wearing blue denim skirts and white knickers, always have, always will i guess. I adore it when a girl is dressed in a way that she often (even while trying not to) gives a little flash of her panties. It's very sexy indeed. Same applies if a girl has erect nipples, never been a tittie fan but nipples have a similar effect on me as a flash/glimpse of knickers. Runs and hides /ashamed
