Panty lines. 80% of my gooning is to panty lines. Ideally briefs, not thong lines, though I'll take those too. I'm definitely a product of the low-rise/whale tail era, but my real love is for demonstrative fuller panty lines, the kind that come from briefs and that are too loud to possibly have been overlooked.

The thought of her being intentionally on display, everyone getting a glimpse of the forbidden and the way the panties accentuate her figure and her shape, makes me cum harder than anything else in the universe.

Really have to have a good ass and a tight body to pull it off, though curvy is okay. A lot of what's posted out there to cater to this isn't very good--flat asses, old asses, or just an overly subtle line, wrong outerwear, etc. But every once in a while, it really comes together, the right ass and the right underwear sitting on it, visible through her leggings or her dress.

I shoot ropes when that happens.
