Give her a dick

You think to yourself that it would be funny if you gave the teacher a penis, so you wish 'I wish the teacher had a large dick.' The teacher is fairly young, in her twenties or early thirties, and is in pretty good shape. You notice as she starts to walk around the classroom, walking a little awkwardly. You manage to get a good long at her as she helps someone next to you with their work for a few minutes. Conveniently, she's wearing leggings, making the bulge expanding out of her groin more visible. Her new organ thickens and lengthens down her leg, and she shifts her position slightly as it quickly becomes erect. You also notice two fairly large testicles visible through the tight material, however nobody else seems to be paying any attention or finding it strange. As she stands up to walk back to her desk, you can clearly see her cock, it must be at least eight inches! She sits down at her desk and continues working on her computer as if nothing happens.
