I'd like to start a list of scenes where you can visibly see a girl's throat expand and contract as a cock gets shoved down her gullet.
It's a unique set of circumstance; you have to have a chick who has essentially no gag reflex, a proper head and neck position, the a neck biology that is suited to show expansion, and a director/cameraman committed to highlighting the action.
There are a lot of girls that have mad Deep Throat skills; yet you just don't see the bulging action. This list is ALL about the bulge action.
I don't know the movie but I know there is a famous example of Janey Robbins deepthroating Ron Jeremy, where you could repeatedly see his cock expand the lower regions of her throat.
Almost certainly the best relatively current example is the one-and-done pornstar "Kalyn" at the sinnistar.com site, where her throat repeatedly bulges upwards so far that it looks like the chest-burster from Alien is trying to escape.
Others include Rebecca Blue in Throatfucks 3, Chastity Lynn (kind of) does it during a brutal scene in Rocco's Puppet Masters 8, and Richelle Ryan did it in Fuck my Skull 3. Another sinnistar Production featuring someone named Jessica Right also did it.
Even our favorite ex-felon, the midget-dicked Max Hardcore, managed it every once in while, specifically with teeny Ann Harlow in Pure Max 12. But bulging throats while Max is pissing in their throats don't count, because that's, you know, gross.
There's an animated gif floating around of Holly Michaels swallowing a giant dildo, where you can see her throat blow up like her neck is having an anaphylactic reaction to nuts. It's awesome, but it's not a real cock... Let's focus n real, not rubber.
Anyone have any other specific examples of specific scenes from specific movies or websites?
