[松波留美] エロコロジー (二次元ドリームコミックス131) [DL版]
#93451 - Just about when he had a full erection, Mistress told me to stop. I had never done anything like it before, but I had read about it a lot. I tried to think of an argument, but then I figured, she was demanding and he just had my cock in his mouth, so what the hey! As I sunk to my knees, she told me to clean him up good so he could leave her and I alone.
