A teenager defied an under-age girl's mother by having sex in her home, Southampton Crown Court heard.

Aaron Cool, 18, formed a relationship with a girl he met through a social network site. However, when he met the girl's mother, she was concerned about the age difference and set ground rules, prohibiting them from being alone in the girl's room.

Prosecutor Siobhan Linsley stated that the relationship lasted for three months before the girl "made disclosures to her mother about the defendant." A friend had also been worried and had already contacted the police.

Upon arrest, Cool admitted to having sexual intercourse with the girl five times at her parents' home.

The court heard that Cool, when 17, had been involved in a relationship with a 13-year-old, but she did not make a complaint.

Now 19, Cool, of Oakwood Drive, Lordshill, Southampton, had his sentencing adjourned until February 24 for reports.
