Hey /adv/, need some advice. In the next few days I will be taking

Lots of lube, lots of foreplay.
You also might have to be prepared to give up.
Like she might chicken or it might be too sore in which case you def don't want to pressure it because (apart from the obvious, that's rape) she'll dry up and tighten up and it won't feel good for either of you.
So yeah be prepared to stop if she asks and also keep checking and verbally asking if what you're doing is comfortable for her. It sounds like it will ruin the mood but it's important and helping her feel safe and comfy comes first.
You will have to go slowly at least at first. Eat her out > then finger her > then and only then can you think about sex

Don't go straight for her v tho
Start off slow kissing her forhead, mouth, neck and shoulders, then stomach and from her feet up her legs before you get to work. Don't rush.

If she asks you to stop, stop immediately and get up and walk away physically. Do not pull out and stay holding/grinding on her. Literally create physical distance until she feels safe again.

Also obviously use protection. Nobody wants to get pregnant their first time.
