My little sister has been growing some big tits lately, and she doesn't even realize it! She wanders around our house half-naked, completely oblivious to her newfound assets. One day while she was sleeping, I couldn't resist sneaking a feel of those perfect globes. When she caught me, she actually gave me permission to play with them more because they would grow bigger that way.
With my newfound freedom, I took full advantage of the situation. I made her drop her pants and let me smother her face with her massive breasts. It was incredible... but I didn't expect things to escalate further when we got home from school one rainy day. Her uniform was soaked through, revealing her bra-less chest and nipples poking through her shirt. The memories of our previous encounter were too much to resist, and before I knew it, we were at it again.
Since my sister loves having her breasts played with, I decided to take matters into my own hands (or rather, mouth) and give her what she wants. I dragged her back inside and locked myself away with her for hours, exploring every inch of her amazing body. Despite being caught up in the heat of the moment, part of me can't help but wonder if this is all just too good to be true...
