I ate out my lesbian bestie and we are still best friends and it won’t change

Im 26F and it happened about 3 years ago, i was in a bad period where i was taking any giving substance i found and thus we were quite high,
She was with her crush with me in the room and they were having steamy lesbian sex but when her crush came, she just went to the bathroom and left her there unfinished laying down like a high vegetable so i stepped in and i started eating that shit like my life depended on it ( mind u im straight )
She came and i came from the satisfaction of making her cum ¿ like i didn’t even touch myself and afterwards nothing was awkward it became the funny joke we bring up sometimes but sometimes i dread her current gf knowing about it cuz she is the jealous type and there is really nothing going on sexually or romantically with my bestfriend like it was a one time thing but im afraid she would want her to take distances with me the day she knows about it.
