Experiencing your fur sprout all over your changing body and feeling Anna's saliva burn away your humanity, your hand strokes your cock faster and faster.
Your whole body seems to grow as muscles are reshaping itself to form your new appereance as a full-blown werewolf. Your fingertips grow sharp claws and your face lenghthens into a wolves' muzzle.
But all changes are shadowed by the burning lust that radiates from deep withing your gut as your human penis shapechanges into a huge wolves' cock that proudly grows out of it's furry sheath.
You don't have to ask Anna for her opinion, her smell tells you all you have to know as you hug her hard, pushing your slick cock up her moist wolfish vagina.
The wave of ecstasy that washes over your body as your pointed cock enters her wet tunnel explodes right within your mind, extinguishing all remaining human thoughts.
Soon both your bodies move like one as you push your member into your mate's cunt over and over again...
