Sissy Training - The Plug

When she first tells you about the plug your first reaction is that there's no way she's shoving that inside you....
But when she pairs it with a release from your chastity....you figure it probably won't be that bad....
So here you are....moaning and groaning like a little bitch as she presses the widest part into you....
And she tells you in a sexy whisper how much she enjoys seeing you stretched like this...
And then as she pushes it home she tells you not to cum.....not until you have the real thing....and when you realize what she means.....you just ache more than before....the real thing....she couldn't mean it....
