Lesbian animations not playing

[LightningDust]

Every time I get lesbian scenes in my playthroughs, whether it be using the Defeat mod or just in general straight up sex through dialogue, when it comes time for the lesbian animations to start the two participants will literally just stand there. they'll undress, make the sex noises, but will stand there blankly. It's really getting on my nerves. I only have sexlab, defeat, and FNIS installed. the straight and gay animations are fine, but lesbian animations will NEVER work for me.
