Regex Multiple email validation

I Want to implement multiple email validation with specific domain using regex separated by ;. Requirement is to allow only two email id separated by semicolon.
I tried regex

^([\w+-.%]+@domain+\.com[~]?){1,2}$

it works fine but it validates email followed by ; . It should work as below

1) abc@domain.com valid

2) abc@domain.com;abc1@domain.com valid

3) abc@domain.com; invalid

4) abc@domain.com;abc1@domain.com; invalid

How to do it using regex?
