As you move your ass down to the base of your dildo I want you work against this movement with the muscles inside your ass, try to push the toy out as it is going deeper inside. Then, when the toy is going out I want you to clench your PC muscle. This push and pull should help the cum flow out. Keep your speed constant, even if your body is desperate to speed up.
Nice and steady sissy boy. Patience is a virtue!
Here is a video for you, featuring my favourite Sean Michaels!
You have until the end of this video to cum.
