Which one of you licks her next?

Hi,
The first time I became a cuckold, while helping her get dressed, I asked her not to wash after he came inside her (she was on the pill).
I don’t know how I got it… Subconsciously, I had already decided that I wanted to lick her with his cream inside. And yet, every time I read about this practice in an erotic story, I would have said never to do it! Today, I’m obsessed with doing it again.
