I have been with my girlfriend Kate for nearly four years now, we first started out on this adventure when we took a holiday for a week. We were driving around looking at the the town where we were staying when we stopped in traffic a motorcyclist pulled up along side us, I noticed he was looking at Kate or more to the point looking at Kate's boobs. Now Kate being a size 12 with large 34gg boobs and this guy was having a very blatant look at her, we both laughed about it "give him a proper look" i said jokingly to my surprise kate pulled down her tee shirt and flashed this guy her boobs. This got us both thinking and surprisingly turned us both on as we later found out. A couple of days later when we were getting ready to go out we were talking about what had happened and i suggested Kate leave her bra off altogether and just wear a tight tee shirt it was an enormous turn on for both of us guys were just starring at Kate her nipples were clearly visible under her tee shirt. That was the start of it all we're now talking about getting Kate set up with with a nice hung guy but are still nervous about taking the next step although its what we would both like to try. Should we take the next step?
