I was 19 at the time and had just got my first car. I was dating my friend's younger sister, she was 16 and still a virgin. After our third date we decided to pull into a secluded spot before dropping her off home. We started making out in my car, kissing and groping, etc. I slipped my hand under her shirt and felt those soft, warm breasts for the first time. My cock was rock hard inside my pants, as she rubbed me from outside my clothing. I undid her shirt buttons and she removed her bra giving me full access to those lovely breasts. I lowered my head and gently began to lick and suck on her nipples. 'God, that feels good' she said, as I gradually began to get her more aroused. I sucked and flicked her nipple whilst caressing the other with my hand. Her head fell back as she let out a low moan saying 'Oh, don't stop'. I carried on working my lips and tongue around her nipples and started to gently stroke her inner thighs with my free hand. She had stopped rubbing the hard-on in my pants, preferring to lay back and enjoy the sensations running through her young body. My hand gradually worked it's way up beneath her short denim skirt, until I reached her panty covered mound. She jerked as I touched her there for the first time, feeling the electricity run through her as I began to rub her pussy. The thin material of her panties were soaked as I carried on rubbing her slit whilst still working on her breasts with my mouth.
Her skirt rode up past her panties as she slid down in the car seat. I could see the moisture had darkened the white material of her panties as I continued to rub her slit, my thumb now concentrating on her clit. I teased her panties to one side and I was now stroking her wet, virgin pussy. 'Please keep going' she said, as I paid more attention to her clit which was now swollen with arousal. She began to pant as my mouth kept sucking on her nipples and my fingers stroked her pussy and clit. I gently parted her pussy lips with my finger using the heel of my hand to keep pressure on her clit. She began to tremble as I gradually worked my finger around the opening of her pussy, her nipples now erect and full. 'Stick your finger in me' she demanded as I continued the stimulation to her breasts and pussy. I plunged my middle finger inside her and she began to shake uncontrollably as her orgasm erupted. 'Yes, yes, oh yes' she cried as I pistoned my finger in and out of her virgin pussy whilst the palm of my hand rubbed her clit. Her juices dribbled over my fingers as she thrust herself onto my hand several times. Her pussy squelched with her juices and her tremors began to subside as I slowed down to a halt. I kept my finger in place as she calmed down after her orgasm, slowly withdrawing it as she gave an involuntary shudder. 'God that felt good' she said, as I sat back and looked at her. She laid back, her young firm breasts with their erect nipples on display. Her thighs wide apart and her panties bunched around her pussy. The smell of sex filled the car as we both caught our breath. 'That was great' she said, 'but I'll have to take these panties off, they're soaked'. She slid her panties down her slim legs and used them to wipe her pussy dry. Her skirt was still up around her waist and I could see she had a shaved pussy. She held her panties under my nose and said 'Look what you did'. 'It must be your turn now' she stated.........but thats another story.
