Imre's daughter said she saw the boy do "disgusting" things with her mother, police said. The girl said she often saw the boy lying on top of her mother, "humping" her, according to police.
Police said the boy initially denied doing anything sexual with Imre because he was worried about getting her in trouble. But later they said he admitted having sexual intercourse with her.
I may be wrong again (thanks aV, now I know too much), but this doesn't sound like the oral sex.
