Susan frowned when she went into Andrew's room to water his plants and noticed that his bed was unmade again. "Oh well, I guess it's because he was late for his big math test this morning," she thought. She remembered him rushing out the door without even saying goodbye.
But then she noticed something that made her stop in her tracks. Laying there in plain view on his exposed sheets was a pair of the panties she had just worn! Andrew must have snatched them out of the dirty clothes hamper in her bedroom. Closer inspection revealed that they were adorned by a combination of dried and fresh semen stains!
No wonder Andrew was late to school. He had more compelling things to do! He'd die if he knew that his mom had stumbled onto this hastily abandoned scene.
She knew that he masturbated, of course. What 18-year old boy doesn't? She even abetted the process by making sure there were always tissues and lotion in his room. She didn't know if he realized she was onto his little secret, but the ongoing presence of semen encrusted tissues in his wastebasket was a dead giveaway that he was doing it.
Susan was glad he wasn't so paranoid that he felt he had to dispose of the incriminating evidence some undiscoverable way; like flushing it down the toilet. She didn't know if it simply hadn't occurred to Andrew that she'd notice such evidence, or if he was sending some kind of message that he knew that she knew, but wasn't ashamed about it. She hoped for the latter, but suspected the former. Either way, even though she felt horribly conflicted, she had to admit that finding these remnants of her son's sexual exploits aroused her -- especially when they were still wet!
But what about her panties? Certainly a normal pattern of post-adolescent masturbation was natural (even necessary) but Susan wasn't so sure using your mother's dirty panties to fuel the process was so healthy. She cringed at the thought of him smelling them and god knows what else. She wondered what he was thinking about while all this was going on.
Nevertheless she needed to figure out her next move. The easy way out would be just to leave things as they were and chalk it up to a little innocent sexual experimentation. After all, she knew that a panty fetish was not uncommon. And since she was the only female in the house, her son had no other source. Furthermore, she didn't KNOW he was thinking about HER as he was using the panties. Maybe he was thinking about someone his own age; or even a mature woman other than her. Those possibilities gave her some comfort.
And even if he was thinking about her; was that so different than Susan getting turned on by her own son's semen-encrusted tissues? After all, she had used them to fuel her own masturbation sessions more than once. And she was thinking about HIM while she was doing it. Does that make her a sicko? This situation was turning out to be more complicated that she initially thought.
The alternative would be to confront him with the scene and force him to talk about it. But there was clearly a downside to that that approach. Was she invading his privacy? Could they really have an open and constructive conversation about his masturbating without putting him on the defensive? Probably not.
In the end, she decided to take the easy (and safe) way out and just leave things alone. But she certainly wasn't going to be leaving her dirty panties around anymore! He'd just have to find a new source.
Meanwhile, Andrew was totally mortified when he got back to his room and discovered his mom's panties laying there in plain view. How could he have been so stupid! What if his mom had seen them? Not only would she know that he masturbates, but she'd think he was a pervert for using her dirty panties. He was totally fucked!
But his body simply gave him not choice. He remembered waking up a little late and started thinking about the panties he retrieved from his mom's laundry hamper, and how "basic" they smelled. He pretended they were Heather's panties (this really cute girl he had a crush on) and imagined that it was the wetness from her aroused pussy (not his mom's) that had soaked into the panties and given them their viscerally captivating scent. Their earthy, animal aroma made him ache with desire.
Fuck the math test. He simply HAD to masturbate. The overwhelming urge he was feeling simply gave him no choice. He pulled the panties out of their hiding place and buried his nose in them. He could still smell his mom's feminine essence and pretended it was Heather's. He thought about her breasts, and how beautiful he imagined them to be. He thought about making love to her and proudly showing her his rock hard cock. She said it was beautiful and moistened it with her saliva before guiding him inside of her.
He knew he was out of time, but there was no stopping now. He stroked himself and smelled the panties while thinking about what it would be like to cum inside Heather. He wrapped them around his erection and rubbed them up and down his shaft. The dried semen from last night made them feel scratchy against the sensitive skin. He continued stroking and thinking about Heather until he finally exploded, drenching the panties with a new load of hot, sticky semen.
When his composure returned, he realized that was already late for the bus so he threw on his clothes and flew out the door without cleaning up his mess. What a fucking moron he was!
Later that day, he didn't know what he would find when he got home from school. If the panties were no longer there, he'd know for sure he was busted. But, there they were, exactly as he had left them. Of course it was impossible to know if his mom had seen them, but for now at least he could pretend that everything was OK. Interestingly, he had no desire to masturbate as he often did after school.
His mom seemed a bit subdued during dinner, but he wasn't sure he wasn't just being overly suspicious. He suspected she already knew he masturbated. She wasn't stupid and even he knew that virtually everybody his age did it. She probably did it too. But what he was really worried about was that she would think he was some kind of pervert, lusting after his own mother! He loved her very much, but he certainly wasn't interested in her sexually. He wished there was some way he could explain.
