You're so lucky to date this chick and find out she's a porn star. It doesn't bother you. You'd really love a little slut to yourself. However, with that also comes the negative part of it - she rants and raves about the big cocks she has taken in videos. Her standards are high in the bedroom. Eventually, you guys make it to her house for a planned night in. You ask her to wear something from a film she's been in, and you're instantly turned on. After some teasing, she begs to see the cock that you have really talked up to her. You're scared, but pull it out. She makes a face. Instead of jumping on it, she says maybe you're wrong in the length that you gave her. She sees right through you, but she's being kind. She insists it's not nearly that long, and says she can prove it. In the bedside table, she pulls out a MASSIVE dildo. She says it's at least 14 inches, and yours... well... isn't even half that size. After fucking herself for a little, she realizes she can't take it anymore and would love to have sex with you instead. You slip in, but it's clear she doesn't feel much. You've watched enough porn to know that she's faking it all now. You should wrap it up, and hope for the best.
