A dark night

It was around 8pm on a Sunday evening when I felt like visiting my girlfriend who did not live very far from our house. Let me start at the beginning , I had just completed my high school and was waiting to be accepted to college, 18 years old and my girlfriend Susan was in high school. Since I knew she would be in school I just had to go see her with probably a bit of making out because she was a virgin and strict on this.
When I got to the house it started drizzling slightly so I pushed the gate open and went right to the door and rang the bell. It was opened by a spectacularly beautiful girl who wore a red mini skirt and white blouse, her feet were bare, she looked at me and smiled invitingly,"hi " all I could look at were her gorgeous eyes and her pert breaststroke straining in the blouse, " I have come to see Susan" I managed all the time being aware of her incredible sexual attractiveness, I started developing a very big hard on staring at her, "the family left for an event and iam the house help and iam all alone" she said, looking straight into my eyes, was this an invitation, ? My hardon increased , I was not too experienced with ladies at that time. The rain increased, " just come in and wait for it to rain" ,she said moving aside" those legs are just spectacular" I thought as I moved and sat on the sofa armrest to remove my shoes. She closed the door turned to face me as I stood up to sit on the sofa and then boom there was a loud thunder bang and the lights went out, I nean it became completely black. I tell you there was no communication verbally after that, I reached for her and her to me we kissed like we were sucking air out of each other, then I pushed her onto the sofa still snogging and she lay as she parted her legs, I only opened my zipper and pulled her panty to the side, she was wet and warm as I put in a finger, then my penis as fast as I could. We fucked very fast ,frantically, like people who know we could be busted at any time, we didn't have the luxury of time, in about 10 minutes we came like a convicts holding on hard to each other and we never stopped snogging as we came. I have since left the area but I remember her every day.
