The adorable snaps show a young bear cub enthusiastically suckling milk from his loving mum – but if you look closely, she doesn’t look entirely comfortable.

Her face suddenly becomes contorted with shock as she lets out a roar of pain – as the over-eager cub accidently nips at her with his razor-sharp teeth.

Photographer Denis Budkov, from eastern Russia, captured the hilarious shots near Kuril lake, in Kronotsky Reserve in Kamchatka, Russia.

Denis, 35, said: “I saw these bears and thought they were cute – the young cub was suckling milk from the mum.

“I noticed the mum’s unhappy grimace – it looked like the cub was not being tender enough with her.

“I even heard a harsh sound coming from the mum, like she was in pain.

“But she was absolutely patient with her cub, and he kept suckling for another 10 minutes.

“It is the most bear-populated place in Russia.

“The bears are pretty friendly but they are still very dangerous animals.
