my wife's mother wore classic briefs always and was quite slender so generally i wouldn't wear them or i'd stretch them. what i would do is when we went to visit she'd leave a pair in the laundry hamper and i'd jack off into the gusset and then she'd put them on and wear them while we were there. i remember one time she stood next to her husband who was sitting at the dinner table and got her crotch and inch away from his face. he said "is that a new perfume ellen?"
Mmmmmm good to hear you love to wear your MIL's dirty knickers and tights too. Likewise my MIL knickers get me so hard and make me spunk so much, I would love to lick her out while wearing her knickers. How old is your MIL? What kind of knickers does she wear?
i too love wearing my mil's dirty panties and tights the adrenaline rush i get wow and the amount of spunk i shoot i wish she would walk in on me in them
