I'm a young 19 year old female who just experienced 3sum pleasures with a mature couple aged 42/38. About 6 months ago I took an temp PA role within an marketing company based in the Midlands. My boss is an handsome guy, 6ft tall, very well built and has a very thick and long cock. I accompany him to all his client visits, which include travelling to London, Bristol and Manchester. I began to to fancy him and many times played with my dildo thinking of him in my bed and sex with my bf became boring. I started to flirt with him whilst in his car and began to wear shorter skirts and more revealing tops. One particular day , it was quite warm and we were travelling to London, I wore a tight but short skirt and a white see through blouse. I'm 32DD, blonde and size 10. My legs were showing all the way up to my thigh while sitting in the front seat. I could see his eyes rolling all over them. The conversation turned to sex, and began saying 'need a bf as he is boring and doesn't satisfy me' . He kept asking me more about my fav positions, how many i have sex etc. I told him I love sex at least 3 times a day, often use my vibrator and lick dressing up in sexy lingerie for my bf. I noticed his cock been aroused and began more intimate fantasies about been fucked by more experienced and mature guys. He couldn't keep his eyes of legs. I said 'bet u know how to satisfy women'. That was his moment of action, he put his hand on my leg and started to stroke. He said' i can show you' . I said lets park up at the next services and shoe me. It was about another 5 miles , in the meantime , his hand was inside my thighs touching my wet pussy. As he parked in a quiet area. my pussy was soaking, I pushed the seat back, opened my legs and he started to push his fingers inside me. Harder I said and he lent over , kissed me and started to finger fuck me hard. His tonque was deep inside my mouth and very quickly he made me cum all over his hand. 'Suck me' he said. I unzipped his trousers and out popped an enormous hard 8 inches cock. I took it in my mouth and started to suck him deep. My tonque rolling all over his cock while hand wanking him too. He was moaning with pleasure. I sucked him deep until I felt his hot spunk inside my mouth. I swallowed it all. We had to leave quickly for the meet. But we met the next evening in the hotel for some hardcore sex. Want more details?
