I tell you to strip naked and that you will masturbate and cum for me. However, you must use my fingers to masturbate with. I sit down in a chair and rest my arm on my leg with my hand just past my knee. I raise two fingers so they are pointed to the ceiling and tell you to get started. Very shyly you straddle and mount my hand and lower yourself onto my fingers and begin to slowly bounce up and down, fucking yourself on my fingers. You begin to moan and whine for me to fuck you as you keep going but I remind you how nice I’m being by letting you masturbate and cum for me. You are so shy and nervous as I ask you how badly you want to cum for me. Fuck my fingers and show me how much you want to cum for me
