You feel a sudden tightness underneath that sagging, squirming mass of belly that encased Sarah,. Your now furry cock was rock hard and already dripping with pre-cum, and truth be told you don't know how long it has been like that. All you know is that its calling out for you to grab it and jerk that frustration out in white ribbons of steamy wolf cum.
You lay down, appropriately enough, in Sarah's comically undersized bed. Paws hanging over the sides and belly jutting up, the muffled screams of the confused and frightened girl echoing out as you digest her in the very bed she slept in.
"mmmmm, good girl" You mumble and reach around to grip your cock with one paw "wriggle a bit for me, ok sugar-bun?"
Chuckling you begin to jerk yourself off with short , heavy huffs of girl scented breath, that hefty paw of yours rubbing up and down your transformed length. It isn't the first time you've wanked yourself in this form but it is the first time you've done it with another creature inside of your belly, filling you up with such a satisfying heft. You didn't care that it was your sister anymore, all you could think about now was he good she had smelt, the way her body had shifted in the bed before you and of course how good she felt wriggling around inside your gurgling belly.
"unnnnnnfff"
You groan and finally let loose, the other paw scratching at the girl so unaware of what was going on just inches away from her, thick globlets of wolf sperm splattering the surface of her fattened prison. You let out an excited, satisfied groan, the spasm of the climax flowing through you.
"goood girllll" you moan "my sweet little sister..."
