It had only been a couple weeks now, but Mateo couldn't have asked for a better deal ... he as indeed very lucky that the woman who found him was his Spanish teacher.
Instead of reporting him to the head director for disposal, or disposing of him herself, she saw the opportunity at hand, knowing all too well that her student now the size of a small doll enjoyed gazing at her bare feet whenever she wore sandals and other shoes that would show skin.
So she struck a deal with the tiny teenager, stipulating that she would provide food and water for him, let him stay in his dorm room, keeping the key for herself, and in exchange he would devote the rest of his life to adoring her feet, and doing whatever she told him to do.
In return for the past couple weeks of loyalty, she offered to stroke him off with her sole as he would lay on his back, licking the ball of her sore heel.
