Custom. Story: Just me in bed in sexy underwear - struggling, rolling around, squirming, moaning and grimacing in discomfort from horrible stomach cramps, that drive me crazy and take up all my strength. You can see the distress in your movements, my facial expressions and hear it in my moaning. I'm perforce and desperately squirming in agony and my body has taken full control. You can see how the cramps build up slowly but also get sudden strikes. I'm straining and struggling hard, moaning and groaning in agony, ending up exhausted and tormented.
