as an ex truck driver i often used to piss beside the trailer in a lay by, one time standing peeing, a car pulled up behind and an old lady got out ran to the trailer. she hitched her dress up pulled her panties down to her knees and squatted. she stated to pee right beside me , neither of us had any shame. i had a glorious view of her open pussy as she peed. then she asked me if i had any paper so she could wipe herself.i went to the cab and got some tissue for her, and she wiped herself , as she stood up to pull her panties up she realised that she had sprayed on them , so she took them
