Impromptu sex with a horny Milf at a punk concert [MF][Public]

This is the first time I am posting to this subreddit, but the story just happened yesterday and is fresh in my mind and I just had to get it down so I could remember the details for a long while.

A small group of friends and I decided to go watch a punk show that came through town and also had a beautiful 3 hour time window of free beer. It was awesome. You get these little tiny goblets that hold about 3 ounces of beer and you just keep refilling your cup at whatever craft brewery tent you wanted. At first, it seemed really silly that the glasses were so small, but after our 15th refill, you definitely appreciated the small size of the goblets.
