It’s just denial, you are used to it, you are addicted to being denied from releasing.

Build up a load that you won’t release, build it up while worshipping my body, while I tell you about how good it feel to be denied. You know it feels good, it feels better than releasing. Blue full balls are a bliss and I’m so nice that I’m going to let you keep them full, not even one drop of cum coming out of that cock.
