I kinda wanted a .com for this, but I was too cheap last night 
The .tk expires after a year.
I did a quick research and if the article is not wrong then .tk domains are free :-P The .tk expires after a year.However, after a year you will need to renew.
Anyway, this seems very interesting idea and I think you can do it in your Loyce.club domain. You won't need to buy domains every time or worried about to renew them after a year.
For example:
