You know you're one of my most loyal friends, right? I love how you do everything for me without expectation of reciprocity. Anyways, bestie, I have a new problem that I need you to fix.
I'm dating this incredible man. Everything is perfect about him, except I don't like sucking his huge cock. It's too big for my mouth... but I think it's perfect for yours. I know you're not gay, so suggesting that you suck my man's cock for me is not a small proposition.
But I'm not asking - I'm telling, and I'm going to give you step-by-step instructions on how to do it.
How does it taste? It tastes like friendship, doesn't it?
