Panties Always Made Him Cum

I had a partner a while ago now (was in my 20's) who had a panty fetish... He was really embarrassed about it, but took the guts one night to admit it to me! We only dated a few months, but I used to occasionally buy him a pair, or let him wear them when we were together,  he used to get really turned on. I would have given him mine but my ass was 5 sizes smaller than his I am sure. I still remember the first time after he admitted it, I purchased him a pair and told him to put them on, then went down on him and she exploded quickly. He always came really quick when panties were involved but I did not mind as he always took care of my needs after.
