Rachael and Chloe are both HORNY

Chloe catches Rachael looking at her, and playfully teases Rachael for staring. Rachael tries to deny it, but Chloe says that she's flattered and doesn't mind Rachael staring at all. It's clear that they're both horny now, horny enough that being family isn't enough to get in the way of having some fun.
