A female student who is usually shy and inconspicuous, who would have thought she had such perverted nipples... They become erect just by touching them. I have to tame them into my sexual preference... I slowly pinch, suck, rub, and twist them, teaching them new pleasures. I use oil and toys to play with her nipples like a clitoris, and pound her portio repeatedly with my big dick, stimulating her until she climaxes completely. My cute, cute Yura has become a premature ejaculator and a super pervert, unable to be satisfied with normal sex.
