Balls

Your wife will do it if you ask for it, be clean, nice, get a drink and show her short porn. she may refuse the first time. her brain needs to do it before she act on it.

Say "Hello dear, had a nice day? Can you suck my balls and tug me off please?" The job's a good 'un.

Get her drunk before you ask. You might have better luck if you shave them first. Wife hates hairy balls, but loves to lick and suck them once I started shaving them.

Your missus don't mind me and my mates hairy balls and arse, she licks them.

Just ask her you pussy.

Thank you that was an intelligent answer.
