the first time was with a rank year ten slut who was probably so loose that no friction was created, and therefore no-one would've been able to finish any kind of job up in there. this also led josh to make 'breen' calls on the female in question, but i digress...
the other time was when he was receiving head from his 'so-called girlfriend' (that's a direct quote) and he was unable to come. his excuse - he'd been so excited at the prospect of getting head that he had to wank.
what a fucking animal.
of course you won't be able to finish the job if you mazz before getting head.
