I can role play either of the characters in the following...
Paul runs a website that features photo sets of teenage boys. The pics are often shirtless and suggestive. Some boys do okay as far as money is concerned. Others are able to put rather fat bank accounts together. It is all a matter of how cute he is and how much of a bad boy he is willing to be. Posing with other boys tends to be the best selling of the photo sets. Then there is the pics that don't go on the regular site for sale to members that are more generous to the boys.
One day Boy A is posing for Paul under the hot lights wearing only a pair of nylon basketball shorts with his legs spread. Just as the man snaps off a shot a boy from school walks in with what he supposes is his mom. They have an appointment. Boy B doesn't want to be there. It's his mom's idea. She heard about Paul from one of her friends and with money being tight she pushed her son into at least trying it.
Tho they don't run in the same circles the boys know each other from school. They blush and turn away when their eyes meet. Boy A mentors the new model and convinces him that it isn't too faggy. And even if it is the money is sweet.
Both boys are 16yo.
