Two things made up Mary's mind for him. The first was Ethel telling him what a rush sex as a male was and how he should definitely try it if he encountered a willing female.
The second was a shift in the wind that carried the scent of the female to him. It turned out that the reason why he hadn't felt turned on was that werewolves, like other canines, were aroused by scent rather than sight. The wolfwoman was definitely in heat!
Apparently, wolf people weren't big on foreplay. She got down on all fours and presented her rear end to him, with tail wagging. In a second they were united.
Oh wow, Mary thought, this is awesome. He was so caught up in the sheer pleasure of the moment that he failed to notice the glow coming from his new mate's silver necklace. . .
