You come on by and decide to wait on your friend, who popped out to the store for a little while. So you're waiting for him to return, waiting with his girlfriend. And slowly, you decide to inform her that his previous girlfriends were super honest with you about him. They all were pretty unhappy sexually. She assures you that this is false, and she's very happy with him.

Then you claim your cock is bigger. She doesn't like this conversation, but defends her man and says he has a great cock. But you have your intentions... and decide to show her. She's in shock! After a little bit of pushing, she decides she needs to give it a try.

And oh boy, you weren't kidding! She's enjoying riding on this one! Wow!
