I think about all the cocks that have been inside her totally unrpotected and how much she loves to have them cum inside of her, and how I MUST wear a condom to be inside my wife, and I like to talk to her about all the cocks she has had inside of her since we got married. I almost always cum while the head of my condom covered cock starts to slip inside of her already full of someone elses cum and I can feel the HEAT and slipperiness start to surround the head of my cock. I have not lasted more than a few strokes for years because of this......especially if she starts telling me about whose cum in in her, and he did not have to wear a condom, and how HARD she came from him cumming in her..........BANG!! 2-3 stroke orgasm for me, and then its time for me to start orally cleaning her up so she gets to cum one last time.
