The Art Class

Harry's at university and like most students, he's hard up, so when he hears about a modelling job at an art evening class, he decides to give it a go.
What could be difficult about getting paid to lay around?
He soon discovers that the difficult part is....he's going to be naked.
At the class, he meets a petite blonde that he christens 'Miss Yellow.'
And, the attraction it seems....is mutual.
