This is a cuck bf custom. Alizae and you are in Vegas and she ended up going to a big p^o^o^l party (after shopping of course) at the hotel when you were stuck at a work conference for the day.
Alizae humilates her little slave boy by making you suck on your fingers she refers to as a BBC. She then tells you how to stroke your small cock while edging you just a little in the process.
