Good son: keep watching
From Create Your Own Story
"It´s hot isn´t it?" you hear someone whipser right into your ear. You startle and quickly turn around. You almost hit your head with the person standing behind you. It´s your bbw aunt Stacy.
"I watched them doing it a couple of times now," she whipsers into your ear. She puts her hand on top of your trousers, right on top of your hard dick. "I can take care of your hard-on if you want! Just come to my room in a minute!" You watch her leave. Her fat ass is swaying back and forth as she walks down the hallway.
You watch Angela licking your sister for another minute. Do you want to go inside their room or follow your aunt?
