A fresh idea for fuck-fest and income

Witnessing his gf take a bathroom and rub herself gives this dude the most deviant idea ever. He calls his acquaintance who always wished to boink this sex-positive teeny and offers him a deal. That rich man eventually gets the romping of his life and this longhaired guy gets the money for a fresh laptop. Well, and what does his gf get? A superb casual bang-out venture right in front of her bf's eyes and a strong climax to go with it!
