Greedily. ..his eyes light up at the sight of the mint and strawberry Lollipop
Aye, his eyes literally strain out of their sockets…until he is given it
He sucks greedily his beady eyes dancing with delight
His belly straining within the confines of his shirt increases literally width wise as he sucks
His mouth is badly smeared, his shirt too by the time he is done licking the mint and strawberry lollipop
your use of images is inspired – I like that even his eyes are involved in the eating of the lollipop – lots to take in
