A man is facing jail after handcuffing a teenage girl on a bed and sexually assaulting her.
Andrew Boyne, 51, also sexually assaulted another teenage girl in a bed and breakfast.
He targeted the younger girl in a flat in Stirling while his partner was out at bingo, a court was told.
A remote jury saw a video of an interview with the victim carried out by police officers in the aftermath of the incident in 2017.
The victim said she "froze" after Boyne had "touched her inappropriately" under her bedcovers when she was 15 or 16 years old.
She told the police that a few days later Boyne's partner and another man went to the bingo, and Boyne handcuffed her "really tight" with silver "chain-type" handcuffs when they were alone in the flat together .
Officers asked her, "What happened when the cuffs were on?"
She replied: "He did the same as he did on the Monday, and I couldn't do anything because I had the handcuffs on.
"I had my pyjamas on my feet were dangling off the edge of the bed."
Boyne's victim told police she was "scared" and later told a relative what had happened.
Now 19, she told Falkirk Sheriff Court the assault had felt "horrible".
The older victim told the court she was 18 and staying in a Bed and Breakfast in Stirling with her boyfriend when Boyne sexually assaulted her in May 2012, after her boyfriend went away for a couple of days.
Boyne and his partner were also staying in the B&B and she went into their room because she was lonely.

She said in evidence that Boyne was "all right at first - kind and funny" but then "started touching me inappropriately".
She said: "I sat on the edge of their bed and he was trying to touch me up, fiddling with my underwear with his fingers and hands. It was a thong I had on and he was fiddling with the string on my thong."
She told prosecutor Michael Maguire: "See when something makes you freeze inside? That's how I felt."
She said it was "quite a sickening feeling".
After a four-day trial, Boyne, of Stirling, was found guilty by the jury of sexually assaulting both teenagers.
He had denied the charges.
Sheriff Derek Hamilton deferred sentence until May 18th for background reports and continued bail.
