Would any women let herself be fed (dog,horse,pig) cum through that device, while beeing tied up?
Purely theoretical question.
If so, then how much would be your limit or would you let your captor decide?
While "drowned in horse cum" might be a funny title for a week, I do not think you can get cum in large enough quantities to make this "device" useful and I think bdsm has no place in anything zoo.
