My wife is a submissive wears a collar when in the house, i wanted to push her a little more the last month. I've always had a thing for her mum and have done a number of thinks with my MIL but she has started to feel guilty about it and so only get a booty call from her every other month.
I text my wife when I was coming home from work told her to get in the doggy position and that I was going to f*** her but shout someone else's name when I was doing her, she asked who's but said wasn't sure.
When I got home she was like I told her to be, as I went into her I lent forward and whispered 'oh Amy you p**** is just as nice as your daughter's'
My wife tried to fight it but I f***** her good shouting her mum's name.
