Tiffany continued advancing on Katie, who was horny but kept trying to resist and figure out if she could control this new ray.
"Woah..." she said, feeling dizzy, before a moment of clarity.
Katie leaned in and kissed Tiffany, no longer caring about her uncontrollable lesbian-making vagina ray.
Katie and Tiffany quickly got more and more intimate, groping each other's breasts, Katie's hands reaching for Tiffany's vagina.
As they continued making out, Katie starting fingering Tiffany's vagina, unknowingly spreading her curse.
As Tiffany came, a beam of light shot out of her pussy and into Katie's chest, making her just as gay as Katie's ray had made Tiffany.
Katie quickly came at the same time.
"Come on, babe, let's get out of here." Katie said, putting her clothes on.
"You're so right. I can't wait to get home!" Tiffany said, smacking Katie on the ass.
