Julie's son Josh arrived at his mom's house just before noon on Saturday. After talking with his mom for a short while he began working on the flooring in her bathroom. It took him most of the afternoon and he finished up the job at around 6PM.
Beforehand Julie had moved everything out of the bathroom including her laundry hamper and put it in the hall just outside the bathroom door. Throughout the entire afternoon while Josh worked on the floor Julie stayed around to make sure he never had any time alone. She wanted to make certain that he didn't get a chance to pleasure himself and for her to miss the show.
After Josh finished up the work he told his mom that he was going to take a shower and get cleaned up before dinner. Part of Julie's plan was to tell Josh that she had to go to the grocery to get a few things she'd forgotten for the dinner she was going to make. She felt certain that while she was gone he would masturbate with her panties. Instead of actually leaving Julie planned to wait outside for just a few minutes then sneak back in to catch her son in the act.
Having Josh taking a shower worked out even better as Julie was able to put her plan into action without having to leave at all. A few minutes after her son got in the shower she called into him to say she was going to the grocery and should be back in about twenty minutes.
Julie knew that if her son was thinking about doing anything that would give him enough time. It would also encourage him to get started pretty much right away. Josh acknowledged his mom and said "okay, see ya in a few."
Julie went into her bedroom and waited behind the door. She had a direct view through the crack at the laundry hamper in the hallway. It only took a few minutes before she heard the water stop running. Almost immediately the bathroom door opened and her naked son appeared.
Julie's heart was pounding with excitement at seeing her son and then things happened exactly as she'd been hoping for. Josh opened the hamper and picked up his mom's dirty panties that she had placed near the top that morning. After inspecting them he put them up to his nose. As Josh sniffed her underpants Julie heard her son say to himself "oh yea, it smells like mom had a good time in these."
As Josh was standing there smelling her panties Julie saw that her son's flaccid cock was already getting aroused. He continued looking through the hamper and pulled out two more pairs of dirty worn panties. By then his cock was nearly erect and Josh started rubbing his big penis as he sniffed his mom's underpants.
Julie watched her son walk back into the bathroom. Her stomach was churning with excitement at seeing his thick ten inch cock was standing at full attention. It had been a long time since she had last seen her son's excited cock and it looked even bigger than she had remembered.
Julie's plan had thus far worked perfectly and she was already incredibly turned on. It was obvious that her thirty-three year old son was about to masturbate his big cock and she was anxious to take advantage of the situation.
Julie's pussy was wet from seeing her son's excited cock again. She was ready to watch him pleasuring himself but she was more ready for what she was planning to do. She walked quietly out of her bedroom and down the hall towards the half closed bathroom door.
The view was perfect as Julie was able to again stand hidden by the door but could see her son through the crack. As she looked in she was surprised by what she saw. Josh was standing in front of the mirror wearing a pair of her panties while smelling the gusset of the pair she'd worn that morning. The third pair was laying spread out on the vanity and Julie assumed he was planning to jerk off on them.
Josh was rubbing his erection through her panty and the thick head of his big cock was sticking out over the top of the waistband. She could hear him talking to himself about how he loved the smell of her pussy as he continued sniffing her dirty underpants. Her son then put his hand down inside the panties and began stroking his cock.
Julie was so turned on from watching Josh that she had started rubbing her clit through her jeans. By then she knew for certain that at the very least she planned to suck his cock. Julie felt extremely nervous but she was also so horny she couldn't wait any longer to satisfy her slutty desires.
Josh was in complete shock when Julie opened the door. He said "I thought you left?"
His face had turned beet red and as Josh stood there with his cock hard inside his mom's panties she calmly told him not to be embarrassed or worry about it. He was frozen in place and didn't know what to say as Julie quickly moved closer to him. Without hesitation she got down on her knees in front of her son and said "this will be our secret."
At that moment Josh was even more shocked and asked his mom "what are you doing?"
Before he could say anything else Julie had started licking the thick head of his aroused penis. She was now completely overwhelmed with the desire to live out her fantasy of being a slut mom. Unless her son told her "no" she wasn't about to stop.
Josh was in disbelief at what was happening and he again nervously asked his mom what she was doing. Julie stopped licking him momentarily then pulled the front of the panties down. She took his thick cock in her hand and told him "I saw how much you enjoy smelling my panties and now I want to show you how much I like your big cock. You don't mind if I suck it do you?"
Josh was feeling very uncertain of the situation as his mom put her lips over the head of his cock and took it into her mouth. Despite the strange circumstances he couldn't deny that having his mom's mouth on his cock felt amazing. He began to moan with pleasure and said "oh god, I don't mind it at all."
