Advice about nipples please

Good evening all. I hope you're all well.

In a nutshell, although my OH orgasms almost every time we have sex (I'll explain the exceptions in a second), I'd love to give her a second one in the same session.

Having looked a little into G-spot orgasms, one piece of advice is to 'get a clitoral orgasm under your belt first'. Assuming that's true, here's our problem: my OH does not orgasm without some serious nipple stimulation, which is absolutely fine. I like to think I know what she likes and how to do it. However, this often means that her nipples are too sore to keep going after she cums; or rather she could keep going but her nipples won't take the required stimulation. Sometimes they're even still too sore the next morning.

Does anyone have any kind of similar experience or advice they could offer? I'd be very grateful.

Maybe try some vibrating nipple toys,if you haven't,so she won't be sore,but will still get stimulation.
