You're my naughty bimbo step-daughter who is in college. You’re taking an anatomy course and you come to me to discuss your idea of your class project. You say you want to do a project on big dicks and dick size, given how much you love big dick and how bigger is better. You’re discussing your idea with me and you can clearly see it is arousing your step-daddy. You notice that my dick is getting bigger and harder, and you realize that I would be a great part of your project. You beg me to measure my big dick as part of your experiment, at first I resist but then you pull it out and mimic me...

You're my naughty bimbo step-daughter who is in college. You’re taking an anatomy course and you come to me to discuss your idea of your class project. You say you want to do a project on big dicks and dick size, given how much you love big dick and how bigger is better. You’re discussing your idea with me and you can clearly see it is arousing your step-daddy. You notice that my dick is getting bigger and harder, and you realize that I would be a great part of your project. You beg me to measure my big dick as part of your experiment, at first I resist but then you pull it out and mimic measuring it as you get all horny yourself. As you are giving me a handjob you decide that you want your study to focus on whether black dicks are really the biggest, or whether white men can compare. You scroll through your phone looking at BBC and describing all these big black dicks, as you stroke your step-daddys dick. You admit that there are lots of big black dicks, some even bigger, but your step-daddys big dick compares nicely. You then let me cum all over your face which you say would be perfect makeup for your slutty self to wear when you present your findings tomorrow at college.
