After receiving a letter, telling him

[Bassim]

I am wondering if my sentence sounds natural. Is it correct to use "high-five with"?

After receiving a letter, telling him he had been admitted at Oxford University, David high-fived with his parents.

I'd delete the first comma.

In the U.S., you high-five someone, you don't high-five WITH someone.
Also, I'd say "When he..." rather than "After."

When he read the letter saying he'd been admitted to Oxford University, David high-fived his parents.
