Suddenly a wolf herm

>You wake up one day to find that cute girl who lives next door knocking on your door.
>You're startled to see she's naked, but her body is covered in light brown fur.
>She has inexplicably turned into a wolf girl.
>You run your hand along her arm in disbelief, finding it to be very soft.
>She looks at you shily with amber eyes.  Her wet black nose pointed at the ground in embaracement.
>While she does still have fingers, her hands are very paw-like and she can only just grasp things.
>She says she needs your help handling certain things.
>You walk with her back to her place and see about finding out what happened.
>As you sit on her couch you realize that between her legs sits a big heavy sheath.
>She sees where you're staring and her ears fold down and she looks away.
>She says she was too embarrassed to bring it up.
>She was worried you wouldn't help her if you saw this on top of everything else.
>You pull her muzzle back up and look into her eyes.
>You tell her everything's going to be okay.
>You don't know why, you lean in and kiss her.
>She lets out a little yip of surprise but she doesn't pull back.
>Soon enough you feel her canine tongue darting into your mouth.
>She reaches so far, it's like nothing you've ever felt.
>After a bit you both pull back.
>She's panting.
>You look down and see a slick black shaft sliding out of her sheath.
>She hides her face in her paws and mumbles something.
>You grab her paws and bring them down to her lap, smiling up at her.
>She tells you it looks so weird.
>So beastly.
>You lean over and whisper into her pointed ear.
>You want to keep going.
>You grab her shaft with your right hand.
>It's slick and warm.
>She yaps out again, reaching up to grab your shoulders.
>She starts bucking her hips into your fist.
>With your left hand you reach down to her sheath.
>You pet it softly and find a pair of sizable balls at it's base.
>You bring your hand back up to the top of the sheath and start toying with the opening that's stretched taught by her canine erection.
>You manage to get a couple of fingers in.
>You chuckle at the sounds she makes.
>It's quite flexible, and you're able to slide your fingers in quite deep.
>She tells you it's coming.
>You can feel something in the sheath starting to swell, pushing at the edge to come out.
>You bring your left hand back up, all while continuing to service her with your other.
>You sniff at your fingers, finding you like the musky wolf scent.
>You present your fingers to her and she laps at them without thinking.
>She pants harder and suddenly starts thrusting her hips with all her might.
>You see her knot slide out of the sheath wetly, spasming.
>You bring down both hands and massage her shaft while she thrashes in your lap.
>She gives a strong shudder and long ropes of canine seed fly out of her shaft, coating her lovely breasts in streaks of white.
>Her orgasm lasts nearly a whole minute.
>As it tapers off you pet her and tell her what a good girl she is.
>You lay down and let her sleep on top of you.
>She mutters something, then tells you it won't be so bad if you're not able to change her back.
>She shuffles a bit to get more comfortable, then her ears perk up as she feels your own rock hard erection.
>You see her tail wag and she looks up at you, telling you you haven't had your turn yet.
