Sucking cocks

Hubby here. My wife has teased me for years that it would be hot for me to let her teach me to suck cock. She says it is something we could do together to push boundaries. I have never had the slightest interest until recently. I started to soften (or is it harden) to the idea.
If my wife told me to be a good boy and suck his cock for her it would be all it would take to start sucking cocks.
