2 young women. Mind control one to fuck the others brain out. Not easy to do with a clit but worth a try.
Would a mutual mind fuck with girls work? With dicks it would be easy but idk about 2 girls shoving their clits into each others brains till orgasm and/or loss of conciseness. As best friends I would hope they climax about the same time so nether has to miss out.
Being controlled to finger each others brains while they have lesbian sex (they aren't actually gay and are resisting the best they can. But it feels good) damaging their friends frontal lobe when they reach orgasm
