You don't… but you might have been saved by the bell.

Just as it seems as though Sarah is about to take John's looming "monster cock" into her eager mouth, her phone buzzes twice snapping her out of her cock-induced trance.

'Ah fuck, let me handle this real quick…' Sarah whispers somewhat irritably as she quickly slides her phone out from her back pocket, seeing who suddenly needs her at this crucial moment.

'Alright, don't take too long' John says with a shit-eating grin as he impatiently rubs his cock head against her cheek. 'I'm about ready to blow.'

'Already?' Sarah teases, sticking out her tongue.

'Shut up, you cheeky slut,' John says, taking himself a little too seriously. He slaps his cock against her cheek now, making Sarah visibly irritated.

'Hang on,' she says. 'I got a text.'

'Ignore it babe. Let's fuck already.'

From a hiding place beside the cigarette machine, you can see everything. You wonder if maybe you can still step in, in some way. But what will you say? They seem about ready to have the wildest sex imaginable, and being a spoil sport may result in Sarah hating you forever. Not to mention that they would be likely to go ahead with it anyway, if not now, then some other time.

You hope to God that the text she just got has a way out of this whole situation.
