It was summer and I hadn't ever gone anywhere past a hug with a girl, I was very innocent until my cousin arrived...
She came home and I was watching T.V. on the couch. It was the second day of 91. So she came and sat with me, and said she needed help with her luggage and that she'd be sharing my room. So I went and got all her luggage upstairs and she said I'd really grown up! It had been a while since we'd seen each other.
So then she whispered in my ear, 'I think your really hot!' I blushed and whispered, 'Your the hottest' and she looked at me and kissed me on the lips!
We went to dinner and she kept her hand under the table on my upper thigh the entire time. She told my parents she and I would be upstairs unpacking her things.
We went upstairs and she started making out with me and shoved me onto the bed. She said she was going to teach me a lot this summer. That day I had touched her breasts and made out a lot with her. That night I slept on the floor and I was shivering and she said get in bed and she cuddled me warm and I got an erection. She felt it and giggled, my face flushed. So then she started to put her hand in my boxers and stroke until I orgasmed. I laid my head in her breasts and fell asleep.
The next day we were in my room and she said she was tired and I said I was too and we both got in bed and she said it was really hot! So she took off all her clothes then she took off all my clothes and I laid on her breasts again. She started to stroke me again and I fingered her and we both came.
Things continued like this all summer. That summer I learned a lot about everything physical, I had even lost my virginity to her. We now are in our 30s and still have fun every day.
