A gynaecologist made a 14-year-old girl take the morning- after pill in front of him after having sex with her at a hotel.
Ong Theng Kiat, 63, also took the minor to a cemetery for illicit trysts, while she was wearing her school uniform.
Yesterday, the short and bespectacled widower faced a jail sentence after pleading guilty to two counts of underage sex.
The court heard that he took a "calculated decision to conceal his illicit relationship" with the teenager, who is 47 years his junior.
They met in 2011 after she signed up for a dating website and claimed to be an 18-year-old looking for "guys".
Ong, who ran his own practice at Gleneagles Medical Centre, sent her a long text message, saying he would treat her nicely if they met. The pair then swopped phone numbers and the girl revealed that she was only 14.
But Ong was undeterred. He asked the minor to meet him so that she could perform sex acts on him in his car, said Deputy Public Prosecutor Sharmila Sripathy- Shanaz.
Then he picked her up from her home and drove her to Bukit Brown cemetery, where they had their first tryst in the back of his vehicle. Ong lied that he was 40 and worked in stocks.
He later drove the teenager to the Balestier Hotel, where he told her to stay in the car while he checked in. Once inside the room, they began kissing and hugging before having sex.
After taking the girl to a movie, he gave her two contraceptive pills and told her to take them 12 hours apart. He even insisted on watching her swallow the first one in his car, said DPP Sharmila.
Then, after they parted, he called and checked that she had taken the second pill.
The next day, he sent her a text message asking her to tell him when she had her period.
Ong met the girl for the final time one afternoon early last year, when he picked her up from school and took her to the cemetery in Lorong Halwa for sex.
She later made a police report.
On Tuesday, DPP Sharmila said that of all the aggravating factors in the case, the wide age gap was perhaps the "most grievous".
Even after Ong found out the girl was a minor, he still pursued her and had sex with her on their first meeting. "For all intents and purposes, this 'relationship' was not the result of the accused seeking companionship of a 14-year-old," DPP Sharmila told the court. "Instead, the ensuing 'relationship' between the parties was one that centred solely on sexual intimacy."
She said the gynaecologist encouraged the teenager to get intimate with him, despite knowing that it was inappropriate and against the law.
The court heard psychiatrist Tommy Tan had argued that the doctor was suffering from depression, which left him incapable of judging the consequences of his behaviour.
But DPP Sharmila said he had the presence of mind to take the minor to a secluded location for their illicit trysts. She argued that he made the girl remain in the car while he checked into the hotel as he clearly did not want to be seen with her. Ong also gave her contraceptives to keep her from getting pregnant and communicated with her by e-mail to avoid her father finding out.
DPP Sharmila said these things all showed that he knew what he was doing and was fully aware of the consequences.
"His actions betray a conscious, considered and calculated decision to conceal his illicit relationship with the minor and a concerted effort to minimise the risk he had exposed himself to."
District Judge Soh Tze Bian adjourned the case to Nov 11, pending more information from Dr Tan and the Institute of Mental Health. Another 11 charges will be taken into consideration when the gynaecologist is sentenced.
The maximum penalty for sex with a minor is 10 years' jail and a fine on each charge. Ong is being represented by lawyers Subhas Anandan and Diana Ngiam.
