I wasn't married, but I was only a teen the first time I made a boyfriend watch a well hung guy make love to me, so that he could see how hard I orgasm when I'm fucked properly, My boyfriend at the time was very cocky. telling all my friend he was my best lover ever. I put up with this for about a month telling him to stop telling people about our sex life. He laughed and said I'm only telling them the truth so what's the big deal. I told him its not even close to the truth as really your dick is actually only quite small and if he didn't stop I'd call my ex to come over and show him how I like to be fucked, to which he said I'd like to see that. That night I called my ex and told him the story, he was knocking on my front door an hour later ready to fuck me. My then boyfriend was 7 inches long but real thin, maybe 5 inches around. On the other hand my ex was was huge 8 inches long 6.5 inches around with a huge circumcised head. My boyfriend wanted a threesome but I said no my ex is here to show you how I like to be fucked to which the ex agreed. I made my boyfriend sit in a chair and watch, I dropped to my knees in front of my ex and released his beautiful big cock taking its head into my mouth not more than a mitre from my boyfriends face, my boyfriend gasped at the size of his cock. As I sucked his lovely big cock the ex and I took our clothes off. once I was totally nude he picked me up and laid me back onto my boyfriends lap, then ate and fingered me to a couple huge orgasms, I was begging him please fuck me babe, this went on for another 10 minutes or so. Eventually my ex said, Now tell your boyfriend who owns your pussy Cathy, I replied you do babe you know that, then he asked, Why are you going to fuck me now, because you are my best fuck ever, that's why. He then said tell you boyfriend to put my big cock in that pussy of mine babe. I never hesitated, I looked my boyfriend in the eye and said, Please put his big cock inside your girlfriend, I need to be fucked like only he cane fuck me. My boyfriend reached out and positioned his cock at the entrance to my excited pussy and sat back and watched as I received the fucking of my life. My then boyfriend never fucked me again, saying he could never compete with my ex.
