For my next lesson I wore a tight t-shirt with no bra, and another short skirt with a pink thong. His eyes were practically popping out of his head as I got into the car. We did the usual lesson for the first half, and then I was instructed to drive somewhere quite isolated.
He was a bit braver this time and touched my leg first, dragging his hand up my thigh and under my skirt, riding it up to expose my pink panties. He slid his fingers inside to rub at my pussy while he undid his pants and took his cock out with the other hand. I undid my belt and he yanked my knickers down so I lifted my bum up and slid out of them. He lifted them to his face and sniffed at them!! Um, ok :) Whatever turns you on I guess. While he sniffed away I got my head in his lap and sucked him off. He moaned loudly all the way through and again was filling my mouth with cum in double quick time.
I let him keep the knickers and we did the rest of the lesson as normal.
