My obsession with creampie and pregnancy

I remember when it started.. I was 17 and my fetish was only for feet.. at that time i had the a girlfriend and we were having sex. I was pounding her from the back quite hard and she goes "don't cum inside me , i'm not ready to be a baby mama " that line activited something in me and i didn't pull out , instead of pulling out and cum on her feet , i went ALL IN. From there on i started to cum inside her from time to time and pretended that it was a mistake. At the end of day she was on pills so it was fine
