Knock Knock..
Knock knock
When you have the house to yourself
When you surrender to her
You don't have to play by yourself when you have mommy!
When you have to lube up to your wrist.
When you have to keep your room quiet, don't wake up
When you wake up just when the dreams about to get good
🔊 When you have to go, you have to go
I Wanna Knock You Up, SIS
Knock knock open up!
Knock Knock
*Knock knock* ... *Echos*
When in heat, you just have to let go
