I have done all 3 many times, Another one is the Mother in law, I spend a lot of time naked at home she is always calling round, knowing I masturbate several times a day she does not mind, sometimes she will sit and watch. even giving me encouragement.
I love doing it while reading stories, like to visit chat rooms as well,
About 3 hours, Sunday mornings with a hangover and the wife watching, i hold back as i enjoy wife watching but don't tell her haha
oh I love it, instant hard on (tiny) and shoot in minutes.
Take some pictures of each other then start again, or just lay naked playing with each other, happening les and less now though.
Finger, also rubbing with a toothbrush does it for me.
At least twice a day, more if im alone.
I love doing it, my wife tickles by bum or my balls sometimes, other times she will just watch,
Yes twice every day, sometimes more,
