You don't

Having just met Ashley for the first time since beginning to work on the set of the show, you don't answer Ashley's question.

There's work to do anyway, as Ashley needs your help stuffing her tits into the shirt, and that's when you realize the little friend in your pants is definitely about to be a problem for you.

"Don't be afraid to touch them John," she tells you as you take the shirt and try to resolve this without touching Ashley in any way that could be construed as sexual, "they don't bite. Much."

As you begin to get more involved in your work, you do accidentally touch Ashley's tits a few times, making her squirm and giggle a few times, then making her moan as you kept doing it.

So far, though, you had managed to do your job (as well as a man can do the job you were in there to do, anyway), without anything overtly sexual happening, but that all changed when you accidentally grabbed a hold of one of Ashley's tits and sub-consciously gave it a squeeze as your cock struggled to free itself and rested against Ashley's leg.

As you stood there frozen in fear, you couldn't even look at Ashley, for fear that she would kick you out, slap you, and cost you your job for losing momentary control of your emotions and groping her tit.
