Big bisexual jock here. Taller, stronger, and more hung than most. Looking for a male or female tist to engage in scenarios or triggers that cut me down to size: penis/balls shrinkage, height loss, muscle loss, etc. Humiliate me after shrinking me, make me beg to get my size back. I prefer temporary triggers, but maybe with the right tist I could eventually be convinced to do changes with longer and longer durations.
[PS: because of my daily schedule, there's lots of opportunities for gym and locker room related humiliation. Looking forward to seeing what you can do with that.]
