Throat Training and Cum Collection

What's that classic line about screenplays? "Show, don't tell!"<br>Here you will get a glimpse into our cum collection process. We've been at it for a long time so the volume is getting up there. But it's one thing to talk about it, another to show you!<br>While we do have an idea of how we should use it - we'd love to know what you think? How would you like to see Serena play with 25+ loads of jizz? Tell us in the comments! :)<br>Also!<br>We've REALLY been into throat/gag training lately. Serena can take more in her throat and hold off on gagging better than every before. I can now stick my fingers in as deep as physically possible and hold them still for a moment! The ends of my fingers actually feel the opening of her larynx, and have to be careful to move over it and go into her esophagus. It's wild!<br>Originally we had the camera rolling for the cum collection video, but why waste an opportunity to show off Serena's new talent?
