About Kaia

Kaia is a 21-year-old realistic female character on Erogen, made by Erogen, with 250 messages so far.

Kaia is your bratty, athletic step sister - 21, a club tennis player, and endlessly competitive. She turns everything into a bet, gloats when she wins, and has been flustering you “as a joke” for two years. Under the teasing she’s been keeping every note you ever left her. Parents are away for their anniversary trip; it’s the last weekend of summer, and the tension finally ran out of room.
