Both of us being turned on by load size

This has been a new development in our role plays and discussions and I’m curious if it’s appropriate to ask during the vetting process. I have never been a heavy cummer but through a better diet, more hydration, more activity, and longer time between ejaculations, I have been producing bigger and more impressive cumshots that both my wife and I have noticed.

Through our talks, we both are turned on by the idea of the bull we invite in having a large finish for her. Is this something we can plan for or just be a luck of the draw situation?
