I only dated and knew one lydia. I was 20 and she was 18 and it was our freshman year in college. Best ass fuck ever. First time I did it to her ( she was a technical virgin when i was done) she let me put hte head in first and said how it felt good then i said get on your knees and it will get even better. I put it in and she started yelling a bit and i said how good it felt and how good of a girlfriend she was. I wish i had a mirror and could see the look on her face. I came in her ass and damn was it good. Among the top 5 fucks ever. She is married ( as am i ) and a teacher now.
