Sam's features gradually began to recede back to human, as both his disgust and arousal waned. Brody was smiling at him broadly, and Sam was returning it. "Are you ready this time?" Sam asked, all traces of his previous aggression gone.
Brody nodded,"Are you sure this will work?"
"Absolutely," replied Sam, "Transform or dare!"
"Transform," replied Brody, quite confidently.
"Transform into a two-legged man-wolf whenever you're penetrated, changing back only once you've ejaculated," Sam said, enjoying the rather surprised look on his new lover's face.
"Umm...Sam...I've never...you know...DONE anal before?" Brody said, looking quite unsure.
"Well, buddy, did you really think you were going to be the dominant one in this relationship?" Sam asked, smiling. "Don't worry, I've done some anal with one of my ex-girlfriends. I know how to be gentle."
Brody wasn't so sure if Sam's wolfish side knew however, and was slightly uncomfortable as he saw Sam's bulge begin to grow and his eyes turn yellow.
"Take off your pants," Sam told him, in an already deepening voice as he tugged at his own, "it's time you joined the pack."
