A woman ended a steamy romp by attacking her sex partner in the genitals with a hot iron.

Kenya Alozie, 31, was sentenced to nine years in prison for burning the man’s privates — and then striking him with a broken bottle in London’s district of Plumstead, the Coventry Telegraph reported.

The man underwent several surgeries after suffering burns and deep cuts.

At the time of the assault on May 15, Alozie’s college student visa was about to expire and she was planning to return to Nigeria. She was caught May 24 at Heathrow Airport.

“Alozie committed a calculated and pre-planned attack,” Detective Constable Duncan Clark said. “She ensured she had a broken bottle to hand and a hot iron to strike the victim and seriously harm him. The sentence imposed clearly reflects the seriousness of this extremely violent attack.”

Alozie was convicted of grievous bodily harm with intent at Woolwich Crown Court on Monday.
