I keep mulling over the idea of getting an inflatable enema plug, kill two birds with one stone? That nice full crampy sensation of a belly full of fluid combined with the heavy, stretched ache of a full ass.
I love watching my belly grow as I'm filled with warm water, feeling it become hard and heavy. Having to wait until I'm given permission to let go. Having your body under some one else's control is so very sweet.
Just to make the choice even harder I spotted this little gem, looks like it would fill me up nicely!
It's about time there was an alternative to the clunky, impractical and novelty chastity devices.
