Kebatu was overheard telling the girls he paid €2,500 (£2,155) to arrive in the UK on a “rubber dinghy”, the court heard.
At the trial, he gave his date of birth as December 1986, making him 38, but court records suggested he was 41.
Giving evidence, Kebatu told the judge he was a “teacher of sports” in Ethiopia and described children as “the future of tomorrow, the new generation”.
However, the judge said he posed a “significant risk of reoffending” and that he became “visibly aroused” by asking the girl to kiss another child.
Judge Williams said Kebatu then “acted ignorantly and repulsively” when he sexually assaulted the woman who tried to help him with his CV.
“She is a confident woman who rightly stood up for herself and, just as importantly, stood up for those more vulnerable than her.”
The assistant chief constable of Essex Police, Stuart Hooper, said the victims showed bravery in securing Kebatu’s conviction.
He said: “They came forward and trusted us with their experience and today I want to say a personal thank you to them for their courage.”
