A paranoid schizophrenic stabbed his mother's partner in the chest as the couple watched television in bed together, the Old Bailey heard.
Nicholas Jones, 34, knifed 45-year-old Paul McCarroll at the family home in Oaks Road, Kenley, south London on November 21, last year.
The victim had been in a relationship with Jones' mother for around 12 years before the killing, the Old Bailey heard.
They were lying in bed together when Jones stormed into the bedroom and plunged a blade into Mr McCarroll's torso shortly before 6pm, prosecutors claim.
Despite the best efforts of police and paramedics Mr McCarroll was pronounced dead at the scene at 6.16pm. A post-mortem revealed the cause of death to be a stab wound to the chest.

Jones appeared at court via video-link from a psychiatric hospital to deny murder but he admitted manslaughter on the grounds of diminished responsibility on Monday.
The prosecution accepted his plea.
Prosecutor Joel Smith told an earlier hearing Jones had a "working diagnosis" of paranoid schizophrenia and had spoken of hearing voices before the attack.
He said Jones was known to mental health services and thought to be suffering a serious psychiatric illness.
"Less than a month before this incident those treating him called police because he threatened to burn down their offices because he believed he had been misdiagnosed," said Mr Smith.
The court heard that after the stabbing Jones was "topless and shoeless in the street shouting his postcode and saying in his words he had f—-d up."
Mr Smith continued: "When police arrived on the scene, he said he was sorry, he had in his words done it, that he thought his mother's boyfriend had been trying to control his mind, he lost it, grabbed the knife, went upstairs and stabbed him.
"Police and London ambulance services were unable to save the deceased's life. A post-mortem was carried out and found [the] cause of death to be a single stab wound to the chest, penetrated to a depth of 15cm.
"[It was] a motiveless attack on the deceased."
Judge Alexia Durran ordered a psychiatric report to be prepared from the clinician at the hospital where Jones currently is, and adjourned sentence until September 27.
