Before I show you the caption there are few rules.
You must of told yout girlfriend (refered to in captions as GF) and she is willing to cuckold you.
You have arranged to go for drinks in a bar. The guy she is going to cuckold you too is meeting you there. He may or may not know the full situation but he should know your Gf wants to fuck him.
You will arrive and you will pay for drinks for all three of you. You may want to drink yours quickly especially if it's your first time.
When you leave, you are going home. She is going back to his place to get fucked. You will walk home but pay for their cab. You will also pay for her cab back to your home where you will be waiting for her later.
The tasks are to be performed in semi-public ( so deserted area of bar, car park, deserted road) but remember be safe!
