My naughty fantasy with my step grandma

[Wetseat 231]

Ive read the rules and I think I can share this fancy here:

like all of you I have a piss kink and my step grandmother is incontinent. I’ve always had a thing for her but now that she wears diapers I really want to piss in her diaper while she is wearing it. I don’t know if I’ll ever get the opportunity and if I do how id do it but her memory isn’t as sharp as it once was. 
If i got the opportunity I would preferably walk up behind her pull open her pants and diaper and piss down into her diaper. I would also be ok with pissing in it while she’s asleep. Probably only ever going to be a fantasy but maybe someday, besides shes a wretched woman if you met her your wouldn’t feel bad for her.
