Anthony Constantinou is accused of groping three women during after work drinks between October 2014 and February 2015.
He is alleged to have stuck his tongue into one woman's mouth after remarking to colleagues that she had a 'cracking arse and t***.
The woman said Constantinou pinned her against aparyition and assaulted her in a 'disgusting' manner on February 20 last year, prosecutor Eloise Marshall told the Old Bailey.
Earlier that day, he is said to have thrown her mobile phone against a wall saying: 'Don't answer phones in my meeting.' The woman said she felt she had been treated like 'a piece of meat' and compared the atmosphere at the Henron Tower office in London to that of leonardo DiCaprio film - The Wolf Of Wall Street.
She left the offices immediately and never returned, said Ms Marshall. Constantinou, 34, is accused of following another complainant into the toilets, grabbing her face and kissing her. The court heard he took the woman into the stock room and sexually assaulted her.
She reported Constantinou, chief executive of corporate business and solutions company CWM, to police.
A third complainant told police the defendant dragged her into a room at the office and kissed her until she pushed him off and left. At the time, she 'shrugged it off' but later that evening at a nearby bar, she claimed he then squeeze her bottom.
Constantinou, from Barnet , North London, denies six counts of sexual assault.
The trial continues.
