A headteacher allegedly set up a threesome with a prostitute who he wanted to spank while she was dressed as a schoolgirl . David Nicholson , 48 , sent the woman explicit messages saying he was ‘ keen ’ on her dressing up like a pupil and was ‘ looking forward to putting you over my knee ’ , it is claimed . The married father-of-four is under investigation after apparently using his school email address to contact an £150-an-hour escort through an adult website and arrange a meeting with her and another woman . Headteacher David Nicholson is accused of sending messages to a prostitute about spanking her when she is dressed up in school uniform as he allegedly organised a threesome with her and another woman . When one of them replied telling him she liked dressing up as a schoolgirl and being spanked , he allegedly responded : ‘ I love this and would be keen. ’ Mr Nicholson , who is headteacher of the 1,000-pupil Costello School in Basingstoke , Hampshire , allegedly organised a liaison in a hotel room on a night when he was due to be working away from home . However , he was forced to call off the plan when the meeting he was using as a cover was cancelled . He promised to stay in touch with the women to set up a new date , it is claimed . Governors at the academy school last night said they were investigating the allegations in The Sun newspaper . Mr Nicholson denies the claims . Yesterday , the two prostitutes said they were shocked to discover what he did for a living . One of the women , aged 20 , told The Sun : ‘ He is a head and his fetish is spanking girls dressed in school uniforms , that ’ s quite scary . In his position he should be trusted. ’ The other woman said : ‘ If I had kids I wouldn ’ t want them to go to that school to be honest . What sort of family man is he ? He should set an example. ’ Mr Nicholson , who is training to be an Ofsted inspector , presents an image of himself as a loving and trustworthy man in postings on social media . Mr Nicholson has worked as headteacher at The Costello School in Basingstoke since September last year . He lives with his wife 15 years Karina , 43 , a local councillor , and their children in the Wiltshire village of Great Bedwyn , which is surrounded by stunning countryside . The Cambridge graduate moved to the Costello School last September , having previously worked as deputy and then headteacher at Abbeyfield School in Chippenham , Wiltshire . Mr Nicholson is accused of sending messages to one of the escorts , showing his enthusiasm for one of them dressing up in school uniform and being spanked . He used his school email to send the imessages . On his Twitter account he describes himself as a ‘ husband and father ’ . In pictures posted online he is shown on his wedding day in July 2000 posing with Mrs Nicholson outside a local church before riding off from the service on a tandem bicycle . After the prostitutes ’ claims were published yesterday , Mr Nicholson said he was ‘ mortified ’ by the situation . Governors at the Costello School said they had asked Mr Nicholson to leave the school site ‘ immediately ’ after allegations about his conduct surfaced . It was not clear if he had been officially suspended , but he will apparently not be allowed to return while an investigation is carried out . Another member of staff has taken on the role of acting headteacher . Carol Bode , the chairman of the school ’ s board of governors , said : ‘ I can assure you all that we are taking matters very seriously . We are following all necessary and correct procedures and as previously mentioned a full investigation is being undertaken by the governing body . ‘ Our first priority at this time is for our students and their continuing education. ’ But she refused to comment on whether the teacher would be given full pay or whether the school had paid for the hotel room he allegedly intended to use for a threesome . Yesterday no one was available for comment at Mr and Mrs Nicholson ’ s £225,000 semi-detached home . Mr Nicholson told The Sun : ‘ I ’ m mortified by the allegations . I am disputing them . Until I know the full details of what is alleged I can ’ t comment further . ’
