Beta Sex Plapgasm Training

The latest in our plapgasm training adventure! I am determined to train cucky to be able to cum JUST from having his balls plapped. He's already trained to cum in his cage using a vibrator, so I am using that as a starting point and mixing in plapping. Each time we train we spend more time plapping and less time with the vibrator. Here is where we are right now. I can't wait until he's fully plapgasm trained
