Fondle her through her undies

Using one hand to sneak into Cao's panties, you begin to finger her, causing her to gasp in surprise as you sunk two fingers into her. She could only lay on the bed and allow you to continue your advances.

You then remove and set aside Cao's undies and lean in to taste her twat. She moaned your name as she held onto your head, allowing your tongue to go deeper into her.

Letting one of your fingers to tease and diddle Cao's clitoris, you smile at her as she threw her head back and let out a loud moan. After two minutes or so had passed, you knew she was on the verge of reaching her limits.

Cao soon moaned your name as she climaxed, letting you lap up her sweet cum. Wiping your mouth clean, you begin to ponder your next move.
