She let out a whimper at first and then a scream as he entered her.  Lucky for her the room they'd locked her in was soundproof and though she tried clenching up to resist him from entering, the oil made things nice a slick and easy for him.  She began begging him to stop as it was rather uncomfortable for her.  When she saw he wasn't going to, however, she began breathing heavily and tried to relax.  Finally, she let herself go limp and the pain lessened.
