Part II of your story should be like this:
You entered her back side instead of her pussy just like those anal fucking porns! so , yeah , she is still a virgin !
Then instead of cuming inside her anus, you pull it out , dom off and spray on her face, again pornstar like, that's why she was starring at you.
So in the pure sense of sex, you were still a virgin at that time as you ain't fuck no pussy yet.
Just my two cents of imaginations !
Cheers
