A Syrian-born airline pilot allegedly tricked a schoolteacher from Haverfordwest into having sex with him by pretending he had to administer ointment on the end of his penis, a jury heard.

Fadi Sbano, 38, even pretended to know a gynaecologist who advised him on how often to have intercourse with her and whether to thrust "slowly or quickly". And on the "doctor's advice", he kept a clock on the bedside table to time the sessions.

The teacher put up with the treatment for nine months before telling her doctor.

Huw Rees, prosecuting, told Swansea crown court: "The allegations here are of rape by deception." Mr. Rees said the pair met while Sbano was based at Gatwick and the teacher was working nearby. In November, 2000, she discovered a rash of white spots and feared that typhoid, which she contracted on holiday some years before, had returned.

Sbano claimed he was in talks with a gynaecologist who was anxious for a certain cream to be applied, the prosecutor said. "He (Sbano) suggested he would apply the cream to his penis and apply it inside her.

Mr Rees said the woman found the sessions "Clinical, not at all erotic". She consented only because she believed it was a proper treatment.

"When the insertions took place, and depending on the instructions of his friend, he would thrust slowly or quickly for anything from one to ten minutes,"

Her doctor told her to find out the identity of Sbano's gynaecologist friend but he "became evasive and never gave his name" beyond the word "Ibby".

"It began to dawn on her that he had devised this treatment in order to have sex with her on his terms."

Mr. Rees said "Ibby" was traced but said he knew nothing about the treatment.

Sbano was arrested at Heathrow while attending a pilots' training facility.

He claimed the woman had invented the entire story about the "treatment". Sbano, from Harrow, London, denies nine charges of rape and 11 or obtaining money by deception. The trial continues.
