"Fuck me again!" you say in your new female voice. "Sounds good to me!" grows Jack.
Jack sticks him member back in. You've never felt anything like this before. It's AMAZING! Suddenly, the pleasure gets multiplied by a thousand! "Holy crap! I can still feel my cock, in yours!" Not only do you feel yourself getting fucked, but you can feel Jack fucking you!
"Oh god, I feel it too!" screams Jack as he keeps on pounding you. He wraps his arms around you tightly. The two of you moan in sync as the pleasure resonates through both your your bodies. Looking down you see Jack's huge throbbing penis actually sticking out from between your waist, despite still feeling that it's inside you.
You grab it and start masturbating it, and somehow still feel the sensations. Meanwhile Jack reaches in front of you and starts messaging your breasts, moaning in obvious pleasure. It's too much for the both of you. Within minutes the two of you white out, completely unaware of the merging of your bodies and mind.
You wake up hours later, by yourself, on your bed panting. Your fur is now dark brown, but retains your white patches. Your body is mostly wolf, though you still remain nimble as a fox. Most curious of all, you've still got a pair of breasts AND a large throbbing penis. Another interesting addition is the fact that you now have nine tails, a mix between fox tails, wolf tails, and some strange hybrids.
