Princess Serena did not like the shoes her boyfriend had bought for her. She had told him the shoes she wanted but he went and got cheaper imitations of what she wanted. She wore them and they were not as comfortable and they made her feet sweaty. She used her boyfriend as her sweat remover since it was him who had bought shoes which made her feet sweat. He went back and bought the correct ones.
When she comes home from work, she has to have her feet serviced. She goes into her slave's room and sits in front of him. She tells him that in order to get out of his cage, he has to please her by pleasing her feet. She wants him to lick her shoe before he sucks her heel. She will take her shoes off and she expects to feel his tongue massaging the aches and pains out of the soles of her feet and sucking her toes.
