As much as it may be awkward. Grandma has seen more peen in her life than Jenna Jameson. Don't underestimate raunchy grandmas, they seen it all.

@ when did we first start talking about grandmas?!

you didn't feel a breeze on your wanker stick? lol it's your house so you have every right to walk around in your boxers. but when having visitors.. especially the in-laws.. you might wanna consider throwing on some track pants out of consideration. although I'm sure she enjoyed it :P

lol at all the comments and the situation

you should keep better track of your " wanker stick "

 happened to me once except my entire penis fell out and when my step mother walked by me she even touched it

at least she knows her daughter has it better then she does and boxer-brief? i heard there better. am a girl and i like to wear boxers with a bra only in the house :D

Look at the bright side, at least your wanker-stick was hanging and not your happy sacks.

she was probebly enjoying the view ;)

did she start masterbating and go "oh it's so BIG!! why don't u come and do me on the couch!!!!"
