Surprise and shock and first time

A girl friend dropped by for a drink on the weekend, we were sitting in the electric leather recliners when out of the blue, she leaned over and put one hand on my breast and her lips on mine and her tongue entered my mouth, my response was shock I did not have any idea that she was Bi but I responded with my tongue meeting hers and sliding into her mouth. Her soft hand slowly made its way to my thigh and it then moved up to my wet lips, she pushed the button for the back of the recliner and laid me back and moved down to my thighs.
Her mouth kisses my lips and her tongue started to lick my clit, I was already way to far gone and started to orgasm, I usually squeeze my legs together and have a massive multiple orgasm but she would have none of that so I reached down pulled my legs up from behind my knees and lifted myself wide open.
Her finger entered my pussy and then as fast as it entered she pulled it out and slide it into my ass and started licking again, her finger was fucking my ass and it felt good the orgasm started again and at that moment she pulled her finger out and stuck her tongue in and was pushing it in as far as it would go only stopping to lick my lips some more, the orgasm was long and hard and noisy. She would not stop and I did not care.
