Good idea! I think that might be how I do it, plus making them vulnerable to Dizzy's addiction.
a way to "turn the tables" on them down the road, like overwhelming them with your size with some special stuff (dizzy's) in the feeder tube, perhaps?
That sounds like a hot idea! I might incorporate it in the new sex system I want to build, which could include both pinning a girl with your weight & feeding whilst making love.
