For me, anyway, I think not knowing how big the phallus was or even what it looked like would instill me with more fear than I could even imagine. Being over it even if I looked down I would not really be able to see it. Then once it started to penetrate me the fear and emotional desperation would really reach another level. It might get to the point where I was suffering so much on it that I would think that whoever is lowering me will stop and have mercy. But then I would feel myself start to lower slowly again and the fear and emotional desperation would reach yet another level.
I'd be begging, pleading for it to end. But I would have no idea when it would end or how deep it will go since I never saw it. I'd even pray out loud at some point. Standard
prayers (i'm catholic) as well as just making some up as i plead with god for help, mercy, comfort, etc. Maybe my faith would even be shaken as I continue to be lowered onto the hideous thing......
