"What?" answered Katie, stunned.
"Jeez, here we are looking at each other's lean, chiseled male bodies with gigantic erections. We're total homos as guys. So let's do it! C'mon, I know you're curious." Tiffany began to gently stroke Katie's erection. "Just imagine how it's going to feel with me sucking on that bad boy."
Katie couldn't deny it felt good. Maybe too good. If sex as a guy was so great, would she even want to go back. But it was getting hard to concentrate, with Tiffany's tongue now teasing the head of her penis. God, no wonder guys went so nuts for blow jobs. . .
