No matter how much you want to, in the end, you simply can't bring yourself to confess your feelings to your former teacher, the risk of rejection is simply far too great, and not something you feel you can live with. instead, you decide that if you can't have her for a girlfriend, then you can at least try out that sexy body of hers, and change the dial to vanishing mode.
Stepping over to the wall close to the stairwell, you hide, waiting impatiently for Gabriela to return so you can put your plan into action. Soon enough you hear the sound of footsteps, as the sexy teacher descends the staircase. Readying yourself, you wait until she reaches the bottom of the stairs, then, before she can see you, you activate the katana, the purple blade springing out as time grinds to a halt around you, allowing you to do what you want, swiftly slicing through Gabriela's neck just above her shoulders with the glowing side of the blade pointed up, something that should, once you press the button again, cause the beautiful educators head to vanish, leaving her unable to see, hear, or call for help, and giving you all the time you need to have your way with her. Figuring that you might as well undress her as well so long as time was frozen anyway, you swiftly do so, before scooping her up and carrying her to the bedroom and undressing yourself, finishing just before time resumes, Gabriela's head vanishing without a trace as she begins to squirm around, feeling the bed and surrounding objects in an attempt to figure out where she was and what was going on.
Seeing your former teachers luscious headless form laid out before you, you drink in the sight for a moment, admiring her long sexy legs and full perky breasts before reaching for her, intending to screw her brains out.
