Thank you for the source; it gives a bit more context. But, it also shows her giving two 12-minute-long handjobs! Who would have that patience, either giver or receiver?!
With how rough she was, I hope she had used some lubrication. She is obviously not keen on fellatio, and is trying to get this handjob finished so she can go back to doing ANYTHING else. A hot girl, but she's not hot for this cock, apparently.
