I love my husband but his cock is so small

OK, here's the deal! I love my husband and don't want to hurt him, but his cock is so small, I haven't had a decent lay since we got married five years ago!

You're his best friend. You have a nice body. I've seen your cock through your suit when you get out of our pool, and it looks huge! And I've seen how you've been looking at me! I need to get laid, and I want you to do it! You have to promise me to keep it quiet and between us, and if I need help in the future, I want to know I can count on you again!

If your game, we can go upstairs and do it now while hubby is setting up the grill. What do you say...?
