New 18yo girl Foot licking on the balcony

Valentina sat on the sofa in the balcony in her white and sweaty socks. I began to smell her sweaty socks very deeply, after which I received the command to take them off with my teeth. I obeyed and did it neatly and put the sweaty socks in my mouth. I sniffed her feet with socks in my mouth, sometimes getting slap from Valentina and orders so that I could work better. When Valentina got tired of this, she ordered to lick her feet. I did it by feeling the sweat from her feet in my mouth. Her feet are very beautiful and salty. But it was humiliating to execute such commands of an 18-year-old girl.. What do you think? (English subtitles)
