The Banana Dare
This is not mine, but I have done it countless times over the last couple years. I find it best to use a Poise Medium pad instead of the flimsy maxi pads, but either way, Enjoy!

* 4 bananas - not too ripe, but not green either - break each in half
* 1 Kotex pad -- medium absorbencys fine
(note: a disposable diaper liner is a suitable alternative)
* 4 liquid fleet susuppositories-
(note: not fleet
enenmas and not solid glycerin suppositories)

(1) place banana halves in a glass bowl and nuke for 30 secs (optional)

(2) empty two of the fleet liquid suppository applicators onto the banana
halves making sure the tips of each are lightly lubricated

(3) empty the other two applicators up the subs rectum

(4) slip the banana hahalves tip-first into the sub's butt, one at a time
(obviously). This may take a couple of minutes. It is a wonderfully
strange sensation for the sub, so no need to race through this. the first
banana will completely smush up. Push as much as you can in with your
gloved hand. It's weird, but believe it or not, they start to go in easier
and easier. By the 3rd or 4th half, they pop right in. This is why you
start with 8 hahalves. By the last half, you're sub will be incredibly
full.

(5) tightly roll the kotex pad in sleeping bag fashion. sticky plastic
side
inward; cotton side facing out.

(6) wipe up the glass bowl with remaining liquid suppository - if
necessary, pop open another and thoroughly lube it up.

(7) insert the rolled-up kotex into your sub's quivering (and very full)
rectum. If necessary, use your finger to push it all the way in.

(8) tightly diaper your sub and finish it off with snug plastic pants.

(9) Allow your sub to lay calmly for a few minutes; then make him get up
stand; answer questions; walk around; whatever.

Here's what is going on. The sub is obviously incredibly full of very wet,
warm and weighted mush. And the quick-acting suppository is screaming at
the poor sub's bowels "void. Void!". But...as the kotex begins to absorb
the moisture from the bananas, it slowly expands and forms a snug and
incredibly effective plug.

The resulting predicament is that the sub feels that intense crampy and
panicky feeling. If they try to tighten their sphincter, the intensity of
the cramping actually grows. I'm not sure why, but it does. And if
they relax their sphincter (and eventually they have to); they find that
they are absolutely 100% sure they are about to fill their pants, but at
the very last second...they don't. The cramping and trembling subsides.
They can actually stand and converse semi-intelligently. But then, in
about 90 seconds, they feel it building again. That nasty wave of
cramping. Everything goes crazy again. They can't focus; can't speak. It's
happening, oh my god, I can't hold it....but then it backs off again. It's
like wave after wave of contraction. Each one gets slightly stronger. And
each one forces the sphincter to dilate a tiny bit more. This can
sometimes go on for 45 minutes or longer.

After 30 to 60 minutes, the sub is totally freaked out. This is
supremely controlling for the domme. You own every part of their
existence at this point. And there are all kinds of creative ways for you
to intensify the mind fuck. Dress him up, take him for a walk, maybe
grocery shopping, and watch him try to mask his contractions and misery.

This is as close to incontinence as most subs get. I mean, with a full
enema, at some point, you release and soil yourself. But with this, even
if you push down a little, the plug means that everything takes it's own
course. It will happen when it happens. And that's that. You won't know.
And the big baby won't be able to tell you either.

But then, at some point the sub's tired and quivering little
sphincter surrenders all hope, and involuntarily spreads and the sub's
diapers fill with a mass of warm, wet, steamy ooze. But that's not it, in
most cases, about 30 seconds after the pressure is releived from the
prostate gland, the sub's bladder will involuntarily empty as well.

This qualifies as an emotionally, mentally and physically intense
experience. Sure to leave any bottom completely chagrined, humiliated and
weakened. Most daddies who have tried this recipe have been utterly blown
away that such an intense form of control and humiliation can be
relatively easily orchestrated with common grocery store items.
