Drama teacher struck off for trying to seduce pupil Black then encouraged the teenagers to mime the sex acts in class, the hearing was told. The schoolboy actor, known only as Pupil A, showed other pupils text messages from Black as he rehearsed for the Queen show "We Will Rock You," it was claimed. English teacher Abigail Watts said: "I heard comments from other pupils about Miss Black liking pupils and I asked what this meant. They said she had been Facebook messaging Pupil A - she told him she had a dream about them having sex. They had not met up but they had been talking about it. Trained actress Black "flirted" with the teenager during lessons at St Joseph's Roman Catholic High School in Newport, South Wales. She contacted him on Facebook asking about his coursework - then began sending him messages talking about sex and alcohol. Black told the boy about a dream in which she performed oral sex on him, then asked him to meet up with her for sex, it was alleged. A Professional Conduct Committee of the General Teaching Council of Wales heard she even grilled the boy's girlfriend about their relationship. The hearing was told Black discussed oral sex and masturbation with the students in class. When confronted by the head of drama about her inappropriate behaviour, Black told him it was just an exercise to get the students into "character." Colleague Sandra Davies said: "Pupils told me that during drama classes Miss Black would talk about sex and she turned the lessons on to a sexual theme. She said she wanted to cheat on her fiancé once before getting married and that she fantasised about having sex on a table in the drama class. "They played a game called "I have never" where she would ask them things like have you ever had a blow job. She would then get the pupils to act out the acts in question. The hearing in Cardiff was told the boy's academic performance had suffered due to Black and he had to retake his AS levels. She was interviewed by police following the allegations in 2011 but no further action was taken. Black, who did not attend the hearing, admitted engaging in inappropriate and sexually explicit conversations with a pupil via Facebook. She denied talking to her class about sex and said the pupils had made up the allegations. But the panel found she had held discussions of an "inappropriate and sexually explicit nature" with her year 12 drama class. They found her guilty of unacceptable professional conduct and banned her from teaching. Committee chairman Peter Williams said: "The conduct in question seriously affected pupils and was not an isolated lapse. Black's actions are fundamentally incompatible with being a registered teacher.
