We are a straight MF couple in our mid to late 40's. I can only say since my GF has been getting laid by other men that our sex life together just got better and better. It just seems to naturally escalate as she gets introduced to more partners along the way. Last year after meeting our first contact of SH we have not really looked back with any regrets. The first time was a test for us. would there be jealousy ? It never happened so we continued to experiment with our new found sex life. What we like about it is the open minds of the guys we met with no need to have hidden agendas. Our first meet invited us for a holiday in Madrid and we went to stay at his apartment with complete open minds knowing it was so he could fuck my GF and for my GF to get laid. They clicked straight away and banged away at each other for a week. Then he introduced us to a friend of his, openly suggesting that his friend fuck my GF. Within hours of meeting him he had screwed her. No fuss or objections from anyone and my GF clearly enjoying it! At Christmas time last year our friend from Madrid came over to England to stay with us and they continued the sex sessions together. While he was with us we drove to the lovely York for a few days where we met another of his friends living up there. Within hours, my GF was being fucked by the new guy we just met. The thing is we know its going to happen and my GF is more and more willing. Since then we arranged another meet through the same group of guys. This guy was over from Spain on business and had our contact details from our friend in Madrid that stays in contact with my GF. He was told that my GF would have sex with him no question and sure enough he stayed with us and fucked her. It now appears that my GF has a reputation in this group of Spanish guys as an easy lay and quite the slut. The truth is, she is and we are both loving the situation.
