You've just been out on a double date. The other was such a jerk, and you mention it to your GF when you're back home. She tells you that you would be a jerk if you had a huge co.... then stops herself. You question her on what she was about to say, but she changes the subject, telling you she will take your mind off him. She strips out of her tight short dress, her big tits spilling over her sexy lingerie. She tries to jerk you off, but she keeps losing grip. If your cock was bigger, she could beat you off better, and it's not long until you cum in her hand, surprising and disappointing her.
You apologize and tell you her you still want to make her cum, but the look on her face is off. She seems annoyed, reluctant to fuck you. She finally agrees, asking you if you're in yet, and then moans loud. Too loud. She's faking it. You said you wouldn't stop until she's cum, so she overcompensates, lying to you, faking an orgasm just so you'll stop. You can tell she hates your cock. You can tell she thinks you're too small.
