Found this animation from a French animator calling himself ArmandetRolande. It's a spoof of 007, where he uses his erection to escape a trap. At the end he uses his massive boner to fill a sexy Russian henchwomen up with cum till she explodes.
She gets pretty puffy, but eventually she fully inflates for a few frames before she bursts.
Here's the link to the video.
