Mawskode bro,
Sounds like you are a bit of a regular at Ginza.
Are you after big tits natural only or OK with enhanced?
If you are OK with enhanced then you should definitely check out Shelley, Jolin, or Amber - all excellent girls busty who do a great GFE, and give service as good as Jay.
If you are after natural only then T- Alin or J Coco are both good options.
They are not as experienced as Jay but they are busty and very keen to please and give a great GFE
