When my wife was pregnant a few years ago, she bought a keggle exerciser to get herself back in shape after giving birth. The kid ended up taking the emergency exit out, so no damage was done to the naughty bits and the kegglerator (not what it's really called, but I like the way it sounds, so I'm going with it) has sat in the back of the toy drawer unused for the past 31 months. I stumbeld across it last night and took it out just for fun. It's a hinged dildo shaped thing with two springs to provide resistance. Each spring has a different resistance level, giving you 3 possible resistance levels, weak spring, strong spring and both springs. The idea is to squeeze the thing shut with your hand and insert it into the pussy, then let go so it springs open a bit, then squeeze it togeter with your pussy (or your wife's pussy as the case may be). Lather, rinse, repeat. It says to start with the weak spring, then work your way up until eventually you can do the contractions with both springs. Well, it turns out my wife is so fucking tight that the only way the thing will open up inside her is with both the springs in, so it looks like she'll have to just straight to the advanced level. Oh, and just to make sure we keep the freaky in this post, after she finished her exercises, I tied her doggy style to the spreader bar, had her suck my dick while I gave her a reach around, then fucked her from behind, pulling out every once in a while to just run the tip over her pussy lips until she begged me to finish her off.
