No idea how to go about this and need advice. I give him pretty, let’s say thorough blow jobs (lol) and I lick his balls a lot, which he loves. Today he admitted that he loves the feeling of when my tongue unintentionally licks his gooch area and he sheepishly asked if I’d be open to essentially rimming him. He’s never had it done to him before, and I’ve never ever ever did it before. Any advice???
