Need help finding a story.

[canadiancharm]

I can remember most of the story but not the title. It is about this man who has a small dick and his one friend who is staying with him lets him know how to make it bigger. He also convinces the guy that it would be better for the wife to be use to the size before he has sex with her so the friend then starts to bang the wife. He basically cuckolds the husband and stretches the wife out. Please help me.
