My girlfriend stayed over mine for a few days last week. When I got back from dropping her off back at hers found her thong on the floor. We didn't gor far when she was over and i think she was wearing it for a couple of days.
I messaged her when I found them and I hinted that I would be smelling them and tasting them which I sometime joke about with her. I loved her reply, see pic above as well as some pics i took of her thong which as you can see has a few days worth of stains on them. I haven't yet but I will be giving them a taste before I wash them as my GF will want them back clean.
