He knew by this point she was on her way home,so he quickly cleaned the panties of as best as he could, threw them on the hamper...it had land on the edge, you decide if you use that later or not..~, and went into her the bathroom, grabbed whatever he could to wipe of his cum...2 minutes wasted, he quickly put everything back and left her room, forgetting to lock it, he went back to the bathroom, put the keys up....crap, 4 minutes wasted...he put whatever seemed out of place back to how it was and quickly went downstairs, sat himself on the couch...and acted as if he was just waiting for her
