Fern and Frieren need to get a perfect gift for Master Stark´s 18th birthday, Fern have no idea what Master Stark would like, but Frieren has the answer, she is learning about male humans and she learned how much they love pretty girls and pretty feet, she also learned some specific data about foot fetish: the feet must be soft and fresh out of footwear so the male human can enjoy the wet and warm feet at peak. So Frieren will offer him a taste of her sweaty feet fresh out of her sandals, she is wearing them and sweating on them to use them as a plus gift for Master Stark, but first she will show Fern this fantastic gift so she can give her an opinion and maybe learn a little bit, Master Stark will be pleased if Fern also joins to this fantastic gift.
