It's not like you couldn't bang at night and show up on time at work the next day.....
Perhaps follow the advice of being patient and trying to set up a date once she's back and then escalate at the date to sex. Until then hold your horses from any further texting..
I have no idea about sexting but most of the game books (like Mark Manson) always say to use texting only for setting up dates. The goal is to get sex, not a friend you text with 10 times a day (even if its about sex).
If she's not interested for a date..well then cut your losses and move on i guess. You bungled it. **** happens. There will be other opportunities and milfs.
