42 year old Helen Walker crouched in her son's bedroom closet peering out through the inch or so crack between the door and the jam. Her skirt was up around her waist and her right hand was jammed down into the front of her bright blue Vanity Fair nylon panties, working her incredibly swollen clitoris as she witnessed the scene before her.
She had come home early because she had dropped off her car at the shop and decided to have the driver bring her home instead of taking her back to work. It was closer and then she didn't need her 18 year old son Erik to pick her up later.
She had been gathering laundry to throw a load in to wash and had been in his closet gathering up his strewn about clothing when she had heard the front door chirp as someone let themselves in. She looked at her watch and figured it was Erik home from school. She heard him race up the stairs and was opening his closet door to greet him when she saw him running into his room with his pants open massaging and squeezing his very large erection as it jutted from his fly. She had stopped herself just in time from bursting into his room. Helen stepped back from the crack of the door wondering what to do. It was obvious what her son was planning and since her car was not in the driveway he had no idea she was even home yet.
She had seen his angry throbbing erection and was amazed at the size of it. Curiosity got the better of her and she looked out through the crack to see him standing across the room. He now had something in his other hand; she thought it was a hanky, the way he was holding it under his nose. But then he released his stiff member and using both hands held up what he had been holding to his nose.
Her breath caught in her chest when she realized that what had been under his nose was not a hanky but the pair of yellow silk La Senza panties she had put in the hamper this morning before her shower. The same panties she had been wearing when she had masturbated before work. They had been very wet and she had even used them to wipe up with when she had finished. Now her 18 year old son was holding them open studying the incredibly stained gusset which was probably still damp because she had gushed so much of her juice into them earlier. She watched as he brought them to his nose again and took a big long pull of her naughty scent.
Then she watched as he stuck his tongue out and swiped it over the mess she had left behind. His body shivered as he tasted his mother's juices and she could see that his steely rod was profusely leaking precum. She knew it was wrong to watch him but since that louse of a husband and father had left her a year ago, it seemed that she always needed to cum and the sight of her son thoroughly enjoying her dirty panties made her already swollen pussy begin to leak into the panties she now wore.
So, here she crouched, peering at her naughty son abusing her oh so dirty panties, working her swollen hard clit, feeling herself climb toward an incredible orgasm. She was so wet that she was making slopping noises as she rubbed her button harder and harder. She hoped he didn't hear and by the way he was working over her panties it appeared that he did not know that she was only a few feet from him about to have a mind blowing cum.
Erik leaned against his dresser and she stared wide eyed through the crack as her took her silky yellow panties and wrapped the cummy gusset around his steadily leaking cock. His cock was completely shrouded in her dirty panties as he began to pump his rigid member with her panties. The sight of her son getting ready to blow his pent up load into her panties was too much for Helen and with an intensity that surprised her, she came hard into the Vanity Fairs she was wearing.
She tried to be quiet as she came but the orgasm that ripped through her body was so forceful that before she could stop it, a gasp escaped her lips. She saw her son stop stroking instantly and turn his head toward where she was hiding in his closet. Helen went to stand up from her crouched position but her legs felt all rubbery and she stumbled forward into his room with her skirt still up around her waist and her hand still in her panties.
Erik stared open mouthed as his gorgeous mother tumbled from his closet where she had been watching him abuse her dirty panties. He tried to stuff his achingly hard cock, panties and all, back into his pants as quickly as he could but was having a difficult time of it because he had been so close to cumming that it would just not go down.
"Don't stop!' his mother said breathlessly to him. "I'm so sorry for spying on you but I couldn't help it! I didn't mean too, but you didn't know I was in here and before I could say anything you had already started to, you know, and when I realized that you were using the panties I masturbated into this morning it made me all wet and swollen and I had to join you. You using my dirty panties on your big dripping cock made me so hot that I just had to rub myself and I came so hard, look," she said as she stood up and moved closer to her startled son. She placed one foot up on the dresser so that her legs were spread and the soaking crotch of her bright blue panties were on display to him.
"See what watching you did to me," she said as she showed her son the large wet stain in her panties and her glistening thighs. She noticed that her son's cock which had started to lose some of its rigidity as she explained the situation to him began to pulse again sheathed in its yellow silk confines.
