You look up into his now bright amber eyes and you can see that the hair on his head has gotten longer and he now has a full beard.
"On the next full moon you will join my pack as my mate." He says in a deeper, now raspy voice.
He begins to have sex with you again as he thrusts his member inside of you and you can feel it stretching even larger this time. Hair covers his body as his fingernails sharpen and curve into claws. His feet lengthen as the big toe disappears and you watch as his ears move to the top of his head and triangulate. You hear a popping sound come from behind him and even though you can't see it you know his tail has just formed. His muscles are even bigger now and his hair becomes thicker and thicker until it is a full coat of fur. His muzzle extends outward, ending the transformation just as he climaxes and he lets out a long, low howl into the air.
You can't control yourself and join him in the howl but it sounds human still and this disappoints you.
"Don't worry my mate. You will transform soon enough and then we will howl together." He tells you, stroking your ass length blonde hair.
You smile, all this should have you scared out of your mind but for some reason it all seems natural.
