I am so disappointed by how fast you came in our last session. I really expected you to have more endurance. No matter, I have the perfect thing to build endurance in you. You are obsessed with my feet. You get hard just thinking about wrinkly soles. I am going to oil up my feet, and make them shiny and slick. I am going to massage your cock, put it in between my toes, and run my slick feet all over it. If you cum before I tell you to cum, I will release you as my sub. I have no room for disobedient submissives. If you want to keep pleasuring me, you will restrain yourself from busting your load all over my oily soles. Can you make it?
