Inappropriate relations

My stepsister caught me jerking off to a porn vid in a wc and as she confessed later she could not think about anything but my sizable stick ever since. She was kinda persistent in her attempts to ride me and finally I gave up cuz she said she was going to student in a week and nobody would ever explore out. Male, this whore always wanted to bang me and although I never opinion about it before we had a titanic time saying goodbye before her departure.
