We all need a stepdaughter like Serenity. This morning, she wanted to go to the pool in her skimpy bikini. But before she was allowed to go, she had to take care of daddy. So he quickly obliged by letting me use her mouth to fuck and always knows to not argue when I push her head down all the way. She made a mess with slobber and snot but still never complained, even when my cock was all the way down her throat when I came and can see her nose flare out as she struggled to breath. But she got to go the pool!
