I'm really sorry this has taken so much time, but I hope the wait has been worth it. There are forty-five GIFs here, with the best reserved for those who can pass the hard questions. Some scenes, especially those from hentai movies, are a little grainy because of the stretch. Enjoy!
Alright, there have been quite a few people asking through reviews and private messages so I am going to say this once and for all: I have no idea what most of the original sources are. I've watched few hentai movies and I got these clips from various hentai forums so I probably know nothing more than you do about where these clips come from. If you guys tell me the sources, I'll add a source list here.

Daily 2nd Place!? I guess there just weren't that many good flashes today.
EDIT: I've made the controls glow so they don't disappear in dark clips. I've also increased the volume of sound #1 to equal that of the other two.
