Yes

Luckily you get home without any problems and you even manage to sneak inside of your appartement without anyone noticing you. You go directly in the bathroom to take a long shower and head straight to your bed afterwards.

You don't wake up until the afternoon on the next day. Curious what the note is about, you call the number and a man picks up. "Hey slut, did you sleep well? Listen, me and some friends will be deployed next week and we wanted to make us a nice last evening over here. And I thought that you might be interested in joining us, we'd pay you of course. I already booked the room from yesterday for the party, so only you are missing. What do you say, up for another round?"

You decide quickly. Last night was a lot of fun and a week would be a long enough break. Also you feel obligated to do this for some reason. That reason might be that they're soldiers or it could just be your desire to relive the last night. Either way, you accept, but you deny to take the money. You might be a slut, but you aren't a prostitute. He tells you when and where you will meet and thanks you twice for "helping them out". Only later that night you realize that you never asked how many friends he was talking about.
