Yes, with her tongue.

Her mind was conveying her to use her tongue to use her taste buds to test it and her face contorted at the thought of licking her palm. Despite the nagging thought mind and her disgusted look, her stomach and pussy fed her curiosity. As her hand inch closer to her face, her mouth parted slightly as her tongue extended out. Her curiosity was willing on her as she wonder what this substance was and she had a hunch what it was, but granted she was a fitness trainer, her actual degree was within the sport science realm. The science part of it when it comes to deduction what things are or do doesn't rely on hunches, but though testing. The scientist deep inside of her egged her to test further.

Without much further resistance, the tip of her tongue came in contact with her palm. At first she tasted a sweet taste, as the rest of her tongue interacted with the substance a salty taste could be tasted as well and then she flicked her tongue a couple of times to lap up remainder. Her lapping tongue was then exchanged with slow sucking of her lips as she tried to gather as much detail as she could. Her eyes opened as she cleaned up all the substance from her hand the taste felt so brief and at first she felt in need for more. Reaching over, she grabbed onto the discard boxers again and brought them up to her mouth and inserting the crotch area into her mouth, she breathed in deep as she again introduced to the taste of the substance. Sucking it off the boxers like it was last time she ate, her taste buds were electrified. She finally was able to come to the conclusion once the fluid was replaced entirely with her saliva from her drenched mouth. Her eyes shifted to the partially closed door and another pervasive thought crept through her mind.

The thought was, why not get more? Obviously you want more of that stuff and your son has the very thing to provide you mouth full of that. The thought elaborated and tried to convince her to open the door that partially close. Just barely in sight she could see her son was seated on his bed and he was hunched over. She wondered what he was doing? Maybe she should check in on him, see about the substance and the package he had concealed in his boxers. Releasing the boxers from her mouth she stared back and forth between them and his barely visible body. She was conflicted on what to do and dwelt on what to do.
