18 year old David Anders lay in his mother's bed, while the faint fragrance of her perfume swirled around his almost naked body. He stroked his enormous hard-on that was straining to burst out of the bright yellow pair of the dirty Hanes nylon high cuts that he had pulled from her hamper and slid on moments ago. He loved the way the soft material felt against his turgid cock and squeezed his large overly full nuts then ran a finger up the large tube running from his balls to the tip of his overly extended cock head and shivered as a large dollop of precum seeped through the stretched nylon. His mother's panties never failed to cause his big cock to leak almost instantly and the fact that he held the dirty gusset of an aqua blue pair of Hanes he had also fished out of the hamper under his nose taking long deep pulls of the intoxicating scent his mother's pussy had embedded in them also helped fuel his ache.
Ever since he had discovered the joys of his mother's dirty panties a few years ago, he jerked off with them as much as he could. When he had first started using them, the only colors she had were white, black and a few beige pairs. Now, ever since she had met and started dating her new boyfriend Marcus eight months ago, the style was the same, Hanes Her Way high-cuts, but the colors were now vivid and incredibly hot. There were bright pink ones, deep green ones, orange ones and some had patterns with little white flowers or purple polka dots. He stilled loved the plain ones, in fact he loved anything that had been snuggled against his mother's nether regions, but the colors and patterns just made them that much more enticing.
Also he noticed since she had started dating that her scent had become much stronger in them, especially after one of her dates. He knew for a fact that she had been wearing the aqua pair he was sniffing on the night before last, when she had gone out, because he had snuck up to the cracked bathroom door when she had gotten home and watched as she slid them down her incredible legs and dropped them in her hamper. When he had fished them out today, he had held them up for inspection and seen that her wetness had soaked through and left a large stain that had stiffened the gusset of her very dirty panties. He now looked at the beautiful stain again before putting his nose right in the middle of it and taking a big long pull. Again his cock throbbed as another pearl of his abundant pre-nut pushed through the yellow nylon.
David reached down with his free hand and grasped his steely hardness through his mother's panties and began to stroke it lightly. His mother and Marcus had gone out for the day and would not be back until later in the evening so there was no need to rush his nut. Sometimes if she just ran to the store he could bust into a pair of her dirty panties in a few strokes but today he wanted to take his time and let it build until he had a huge load pent up that would literally soak the silken undergarment.
As he lay with his eyes closed relishing her musk, he brought to mind his beautiful mother. She was 41 but was still an incredible knockout. She had large high breast and incredible full hips and could still rock a bikini. At times she looked like a super model with her mane of auburn hair and perfect lips. His father must have been a real shit to have left such a beautiful woman with a small child. If he felt particularly brave he would watch her from his bedroom window as she tanned out by their pool and jerk a load into the panties she had just taken off before donning her swimsuit. He had also jerked many times into her bikini bottoms when she was done and had even left a load in them once knowing that she would wear them in a few days when she sunned again. He had busted big as he watched her walking around in that bright green bikini with the knowledge that the day before he had left his mark in them. The memory made his swollen balls give up even more of their slippery precum and allowed his hand to slide effortlessly over his turgidness.
While David was lost in the reverie of his mother spending the day at the pool in the cum-filled green bikini and steadily increasing the speed with which his hand was pumping his precum slickened, panty covered cock, he had no idea he had an audience. Margaret Anders, David's mother, and her boyfriend, well boy toy really, Marcus, were now standing at her bedroom door which, in his haste to get at his mother's panties, David had left ajar. She had forgotten her overnight bag that she had wanted to take just in case they had decided to stay over on their day trip to the bay. The two of them had been watching her son being nasty with her dirty panties for at least five minutes. She had almost barged in when she had realized what she was seeing but Marcus had stopped her. His big black hands had grabbed her around her waist and held her in place.
"Just watch." He said and pulled her close to him. She could feel his very large black dick start to grow against her ass as he grinded her bottom from behind.
"Don't tell me that ain't hot," he whispered in her ear. His hot breath on her neck and the sight of her little boy, well not that little by the looks of things, stroking with and sniffing her dirty panties made her pussy twinge. She felt a rush of juice begin to lubricate her swollen labia and almost without thinking lifted the front of her tiny sundress and began lightly teasing herself through the neon orange high cut panties she was wearing.
"It's wrong," she said thickly through clenched teeth, "he shouldn't be doing that to my dirty panties and we shouldn't be watching!"
Marcus slid his hand down her taunt stomach and pushed it under the lace waistband of her pretty panties and dipped one of his long dark fingers into her now saturated quim, "You might say no, but she," he flicked her hard clit a few times as she shivered against him, "says nothing but yes! And, you don't seem to have a problem when I abuse your dirty pretty panties."
"You're not my son," she whispered back at him still trying to resist but knowing by the puddle forming in her panties that she indeed found it hot that her son apparently loved the smell she left in her panties. She also realized that the panties he was currently holding under his nose and sniffing with fervor were the ones she had worn the last time she and Marcus were together. She had left them on while he had pounded her and filled her twice with his giant loads. She had just pulled them back into place afterward letting all their mixed juices drip into them. They had been a total mess when she finally peeled them off and threw them in the hamper when she had gotten home.
Here her son was now, sniffing on her and Marcus' mixed juices and stroking his big cock looking like he was about to blow into her yellow Hanes at any minute. Without warning, David pulled the dirty gusset from his nose and stuffed it into his mouth, sucking hard on the cum-stiffened material. She almost came but controlled herself with what little sense she had left. That was about the naughtiest things she had ever seen and she could tell by the steel pipe in Marcus' pants that he was also enjoying the show her son was putting on. Giving in to the heat of the situation, she reached behind and pulled Marcus' zipper down. Her hand snaked into it and began to caress the black monster that was straining against the purple pair of Hanes he had her put him in before they had left. Her hand became slick because he too was leaking precum profusely.
As quietly as possible she fumbled with his belt and opened the button. His pants slid to his knees and she felt him press his pantied cock against her panty covered ass. She could feel his wetness against her and it only made her swollen pussy gush more. His finger kept a steady rhythm on her rock hard clit causing her knees to feel weak. Marcus held her tight as he humped his 11 inches against her ass. He reached down, pulled his panties over and let his monster slap against her. Marcus bent her forward slightly pulled the crotch of her sopping orange panties over and in one fluid movement slid the entire length of his rock hard black cock into her.
