Help writing sex scene

I posted this elsewhere orignally but I thought it’d get a better response here.

I’m not actually sure how to describe it. And without being vague this is for a story on my account called Xanthippe and Silga’s Adventures. (Note this is more of a comedey slice of life story with some drama.)
So Xanthippe is very boisterous and loud. And she’s proud to be a lesbian for at least she likes pussy. (Cough) I was thinking that I should include a few sex scenes with her throughout the story. Most of which are either there to reflect how she’s feeling emotionaly or it’s significant to the plot.
Silga will have sex with one other woman before Xanthippe. The idea is that I want to build up their friendship/romance first before Xanthippe and Silga fall in love with each other.
And when Xanthippe and Silga do finnaly have sex I want it to be meanigful for both of them.
