Need help with long distance role play situation.

Me and my gf are going to be apart for some time and I am planning a role play to keep both of us entertained and horny. Role play is this : I lost her in a bet to some random guy. Now she has to be his slave for 3 days. This guy, lets call him 'dude', will message her on WhatsApp from a different number than mine(I have 2 connections) and give her instructions or tasks to do or to send him pics...basically his wish would be my gf's command and she will have to do this. Dude can force her into embarassing situations like go for a walk without a bra and thin top etc. Etc.

So I will be alternating between the roles of dude and myself. During the day I would be dude and at night we will just talk normally and discuss everyday things and all.

So now the problem is that I am having trouble coming up with tasks, punishments, commands, poses for pics etc. I want it to be entertaining, sexy and not just repeat the usual stuff posted on every sex blog over the internet.

So help me reddit. Please suggest some tasks, punishments, commands etc. For me to give her as her owner. She will be my little slave for 3 days :).
