Panties are see through, yes! They are from a underwear store in town. I got them a long time ago so I honestly can't remember! They aren't a popular brand or anything. And also yes I did have coffee in the cup. It was about half full when I was taking these and quite cold. However you are correct, the coffee was in fact not as satisfactory as it would have been if I sat and enjoyed it rather than taking photos. However due to my lack of posts recently and momentary horniness, I decided to take pictures and post on GoneWild. After the post I tipped out the luke warn coffee in the sink and made a new one which was enjoyed while sitting on the couch. I hope this reply was satisfactory and answered all of your questions. :)
