Help a McShepper out?

Hello McShep fam, can someone point me in the direction of the fic where John and Rodney know they can’t act because of DADT and end up setting up a secret radio link where they have radio sex each night? Radek finds the link at one point and keeps their secret?

Thank you in advance. Also, I have been reading so much Radek/Rodney recently and it’s my new favourite thing so recs appreciated.
