LOVEMORE Dube (25) only stopped when the terrified woman asked how he would feel about such a brutal sex attack against his own mother or sister.
The vicious attack by Dube, a Zimbabwean national with addresses in Limerick and Cork, resulted in the middle-aged woman having to be tested for both HIV and hepatitis.
The tests proved negative.
It also emerged that the keys to the woman's home were later found among Dube's possessions at Cork Prison.
Dube pleaded guilty at the Central Criminal Court to raping the middle-aged woman at her home in Cork on July 23, 2012.
Mr Justice Paul Carney said it was a very disturbing attack.
"(The rape was) violent and insulting and left the victim severely traumatised and injured. She was particularly upset that this happened in her own home where she was entitled to expect safety and sanctity," he said.
She was left further traumatised by having to undergo HIV and hepatitis testing due to what was described as an incident in Dube's past.
Mr Justice Carney registered Dube as a sex offender and imposed a nine-year prison sentence with two years suspended because of his guilty plea and remorse.
Dube had laughed at the woman as he held her down and raped her. During the attack he repeatedly slapped the woman and bit her breasts.
The victim said she believed the attacker was enjoying her suffering and had "evil" in his eyes.
"The fear I felt could not be described ... I prayed to God, Our Lady, the angels and my late grandmother to help save me," she said. As he raped her, Dube laughed at her and insulted her by calling her "a bitch" and "a slut".
The attack only stopped when the woman desperately asked him how he would react if someone subjected his mother or sister to a similar assault.
She managed to push him out of her home. The woman did not have a phone to raise the alarm and was terrified until her brother and partner arrived home an hour later.
"I hope God will forgive you because I never will. I feel like I have been handed a life sentence yet I committed no crime," the victim told Dube.
