She opened her throat and took it deeper. Each stroke jammed his cockhead so deeply into her mouth that she couldn't breathe.Her pussy was screaming a...t her. The tight cunt drew her attention with itchings and urgings that distracted her until her head and hands slowed and stopped.She slowly stood and stared at her father. He lay on his back in the tub. She slowly squatted down. Hot water ran off her back. Her pussy felt even hotter. It was boiling. And she knew she had to feel her father's big.
