Evan lifted the hamper top and began rummaging through his mother-in-laws dirty clothes. Almost instantly he found what he was looking for. A pair of his sexy mother-in-law's dirty silky panties! They were full cut bright green with a wide lace waistband and cute lace trim around the leg openings. A nice pussy stain was embedded in the crotch and the sight of it made his bloated balls tingle. And, they were also one of the favorite pairs he liked to relieve himself into. He and his wife Carol were living with her mother for while and it was nice to have ready access to her dirty under things.
Evan had been using his mother-in-law's dirty panties to jerk off in for as long as he could remember. Way before his wife and he got married. As a matter of fact, before he and his wife had been dating and they had been only friends. That had to be about 20 years running now. He LOVED the way Judy, his mother-in-law, made her panties smell. He even liked them more than his wife's or her sister's dirty panties and they were pretty good to sniff on too.
He held the stained gusset up to his nose and took a big inhale of the lovely fragrance Judy had left in them for him. Wow, it never ceased to amaze him how her musk instantly could bring him to a raging hard-on. Her smell made him ache. He actually throbbed inside the pair of her white silken panties he was now wearing. He had snatched them from Judy's hamper earlier in the week. They had a seam up the back which made them a little tighter and held his aching cock so nicely.
He took another big sniff and reached down to unzip his jeans. The big silken bulge protruded from his zipper and he cupped it in his right hand still holding the dirty panties to his nose with his other hand. God, he couldn't get enough of her smell. He had been blessed with a rather large cock and it now stretched the thin nylon almost to its limits. He squeezed his stiffened member and a big dollop of pre-cum soaked through the panties he was wearing. He sniffed again, imaging his 55 year old mother-in-law licking the large drop off her straining panties. Just that thought forced another bigger drop to push its way through.
He pulled his leaking cock out of the panties he was wearing and began to stroke it long and slow. The more he stroked the more pre-cum flowed freely from the swollen piss slit of his enlarged member. He speeded up his pumping and could feel the all too familiar tingling in the base of his balls that signaled his impending nut. Not wanting to cum in the green pair he so lovingly sniffed, he reached into Judy's hamper again and came up with a very shiny blue pair that he had not seen before. He loved that his mother-in-law bought new panties on a regular basis and never a cotton pair in the bunch. Even his wife had a few pairs of ugly cotton ones for "that time of the month."
Evan carefully laid the blue panties on the counter next to the sink, gusset up, so that he could shoot his pent up load in the stained crotch. He could see where the cotton gusset had been stuck to his mother-in-laws creamy pussy. The stain was quite large and crusty and he could only imagine how wet she had been when she removed them. If he hadn't known better he would have thought that Judy had cum in them herself before depositing them in the hamper. They were that used!
He aimed his big fuck stick at the dirty crotch and thought about how sexy his MILF mother-in-law would look with the wet panties plastered to he juicy love mound. A long string of pre-cum dripped from his overly swollen cock head and attached itself to the center of the naughty stain he stood aiming at. Seeing the strand stretching from his cock to the dirty gusset was just too much for him. He tugged harder on his rigid manhood and was about to unload what felt like a gallon of hot sticky cum in the panties when suddenly the bathroom door opened with a bang and there stood his mother-in-law in the doorway.
Evan tried desperately to stuff his straining leaking cock back into his pants to no avail. He was caught red handed with a pair of his mother-in-laws dirty panties in each hand and a rather large, now deflating cock still dripping pre-cum hanging from the open fly of his jeans. His face turned bright red he stood there looking right at Judy waiting for her to totally freak out on him.
The tension in the air was so thick it could have been cut with knife. Silence filled the room as Judy, with a stern look on her face, and Evan stood staring at each other, eye to eye. To Evan it seemed like and eternity passed.
Just when he thought he would not be able to stand it any longer, Judy took a step into the room.
