Now that the idea has been planted in Emma's head, she knows she needs to try the vibrator. She sneaks it out from under the tree and settles behind the couch to press it into her meaty twat while Harlow keeps their parents busy. Logan finds Emma fucking herself, and slides his hard cock into her twat from behind. When Harlow spots them, she excuses herself from the conversation to join in for a sibling threesome. Soon Emma finds herself with her stepbrother's cock inside her and her face planted in her adopted sister's cooch.
