I thought tumblr had cracked down on porn.
I've seen this a few times:
@onomatopoeia - I think at this point you should just have a "sexy gif" thread since we've wandered far afield from tanlines.
That's all of the animations. I scrolled through 340 pages in two days for this thread. The animations appear randomly. A saved file is useless for this thread. I saved lots of tanline pics, but I posted the animations when I found them. I would appreciate it if you and a few others would stop posting the same pics every few pages.
