I've had lots of nice discussions with ladies about different stimulating practices, and have at least tried them out in cyber adventures; no reason the following couldn't be tried with an enemate in real life!
Imagine the cozy scene, a lady-friend lying across your lap, a bag hanging above filling her bottom with warm soapy fluid; in the course of play, about halfway through the filling pull out a small vibrator and tell her this should help her take the rest - switch on the vibe, spread her hips and ease the vibe down into her pussy, keeping the nozzle in place with the other hand. I call it "using a pacifier", a way to take her mind off pressure building up in her bottom; just gentle play all the way til the end...
...once the enema is finished, continue to push the vibe in and out a while; then announce that the soapy fluid needs a little agitation before she can expell! Remove the vibe and dip it in vaseline, then gently pull out the nozzle and replace it with the vibe; a nice gentle push and down it goes...she'll feel some real vibes, smooth in-and-out action, keep it up as long as she can stand it - hopefully the enema was done nice and slow and there's no heavy cramping.
Anyway, this sure sets gals' minds reeling when I've tried it in cyber play - just a simple procedure for spicing things up, would like to hear what others have tried!
