"Lily"
"Yes daddy?" She replies
"You feel an overwhelming urge to suck my dick right now"
You see the light in her eyes change, she starts drooling "c..c...coc...cocky?" She whines, lily then rushes over to you tripping over herself, desperate to get to your dick.
Just for the fun of it you make her lips inflate making them the perfect cock-pillows for you and making your dick double in size, just so she has some fun too.
