I Imagine Somebody Else Fucking My Wife Everytime I Fuck Her

I was lucky enough to fuck her last night...
"Mmmm that feels great...you are so fucking tight"
"Mmmm Bob ..err Ian...sorry love"
"Dont worry...lets imagine its Bob who is fucking you...call me Bob...say what you would say to him..."
"...ok...oh god Bob thats so big...I love your cock...you fuck me so much better than Ian does with his little dickie...I wish you could fuck me like this EVERY night..."
...and so it went on...
