Efter festen - interracial one night stand

It's the end of the work's annual party and Caryn is talking to a guy from finance called Yardley. Halfway through the conversation she notices an absolutely massive bulge in his trousers. Despite this, he's incredibly charming, so much so that she invites him back to her house. In the taxi she finds out what that bulge was - he has a massive cock, and now she wants it all.
