Youmu could only look at Lisa with confusion as the kittygirl climbed up onto her lap.  Her teachings back in the Elven homelands told her about the different races of the world, of course, but she had never met a kittygirl before, and the teachings didn't say anything about their appetite for sex.  As soon as Lisa kissed her full on the lips however, she tried to back away (with no success, as her back was already against the wall of the tub), her eyes going wide at Lisa's actions.  "Wh... I, uh, I think I'm done in here now, yeah..." she said, gently trying to shove Lisa off her lap.  She let out another strangled cry as she felt the kittygirl's tail brushing against her crotch.
