So, I will shamelessly admit I have a panty fetish. Just as prominently, I have a cum-play fetish, so that's kinda how this comes about. Something about fucking her, then pulling out so I can fill up her underwear, before she pulls them back up, or just cumming on them while they're pulled to the side, is so hot to me. I like to think about filling her panties with a nice, thick load, then having her wear them all day. Then, at the end of the night, I take them off her, bunch then up and gag her with them while I fold her in half and fuck her senseless.

Maybe it's one of the odder kinks, I don't know, but I enjoy it quite a lot. It's always a guaranteed turn on for me. Hell, it doesn't necessarily have to be panties (that's just the best option imo), cumming on whatever she's wearing works too.
