You slowly slide to the floor, your heart beating a mile a minute. You're still not exactly sure what is happening, except that a werewolf woman is sucking you off, while her husband watches. A werewolf woman that just bit you.
You can't help but find some odd erotic pleasure out of this situation, as messed up as it is. You lean your head back, taking deep breaths, let out a whimper of pleasure.
This causes you to pause. You've never whimpered in your life. You catch a glimpse of your hands. Your fingernails have grown out into claws. Long brown fur is starting to grow on your arms. You feel around with your tounge and find your teeth are growing out into fangs.
You dig into the wood floor with your claws as you near climax. You hear your clothes start to tear as your body mass increases and shifts. Your chest starts to barrel out. Your shoes rip apart, you feet grow and stretch, becoming digigrade.
You reach climax, blowing your load and the last few changes come fast and quick, your ears shift up your head as your face pushes out into a snout. You let out a long, loud howl as you finish your transformation.
