su does not work that way. Period.
ssh can work that way if you arrange for key based authentication and explicitly tell it to forward the key.

ssh-add
SSH-ADD(1) BSD General Commands Manual SSH-ADD(1)
NAME
ssh-add -- adds RSA or DSA identities to the authentication agent
SYNOPSIS
ssh-add [-lLdDxX] [-t life] [file ...]
ssh-add -s reader
ssh-add -e reader
DESCRIPTION
ssh-add adds RSA or DSA identities to the authentication agent, ssh-agent(1). When run without arguments, it adds the files
$HOME/.ssh/id_rsa, $HOME/.ssh/id_dsa and $HOME/.ssh/identity. Alternative file names can be given on the command line. If any file requires
a passphrase, ssh-add asks for the passphrase from the user. The passphrase is read from the user's tty. ssh-add retries the last
passphrase if multiple identity files are given.
The authentication agent must be running and must be an ancestor of the current process for ssh-add to work.
The options are as follows:
-l Lists fingerprints of all identities currently represented by the agent.
-L Lists public key parameters of all identities currently represented by the agent.
-d Instead of adding the identity, removes the identity from the agent.
-D Deletes all identities from the agent.
-x Lock the agent with a password.
-X Unlock the agent.
-t life
Set a maximum lifetime when adding identities to an agent. The lifetime may be specified in seconds or in a time format specified in
sshd(8).
-s reader
Add key in smartcard reader.
-e reader
Remove key in smartcard reader.
FILES
$HOME/.ssh/identity
Contains the protocol version 1 RSA authentication identity of the user.
$HOME/.ssh/id_dsa
Contains the protocol version 2 DSA authentication identity of the user.
$HOME/.ssh/id_rsa
Contains the protocol version 2 RSA authentication identity of the user.
Identity files should not be readable by anyone but the user. Note that ssh-add ignores identity files if they are accessible by others.
ENVIRONMENT
DISPLAY and SSH_ASKPASS
If ssh-add needs a passphrase, it will read the passphrase from the current terminal if it was run from a terminal. If ssh-add does
not have a terminal associated with it but DISPLAY and SSH_ASKPASS are set, it will execute the program specified by SSH_ASKPASS and
open an X11 window to read the passphrase. This is particularly useful when calling ssh-add from a .Xsession or related script.
(Note that on some machines it may be necessary to redirect the input from /dev/null to make this work.)
SSH_AUTH_SOCK
Identifies the path of a unix-domain socket used to communicate with the agent.
DIAGNOSTICS
Exit status is 0 on success, 1 if the specified command fails, and 2 if ssh-add is unable to contact the authentication agent.
