Your dick snakes it way into places unknown.

Without any intent on your part of Petra's her wagging tail and her ass has excited your dick and it starts to snake it's way up between your body's. As Petra ties to make room for your dick between the two of you. The tip of your dick pushs against her anus, Petra lets out a moan as she ties to adjust your dick between you. As she wiggles this way and that the head of your dick slips pass her anus and hits the mark. It pieces two and half inches into her cunt, Petra lets out a shrill shriek of excitement as she realizes that your dick is now in her tight little cunt for the first time.

Molly comes over a little worried about her pup as she notices that she is connected to you by your dick. She is not upset with you or her pup, just a little surprised to see this turn of events when, Petra knows full well she needs to be full grown before she goes looking for this pleasure. As Petra tries to come to terms with whats going on your dick grows into her cunt feeling her up, Petra of course lets out a grown as she feels your dick grow into her tight never before fucked cunt.

Molly looks at the little pup and simply asks " A bit to much for you dear?"

Petra lets out a light moan and says " it feels great but it's really big I am not sure I can take it all yet mother."

Molly smiles and says " You know it would best to get off him before it gets any bigger right? I know myself and Kamrin have taken his dick and his Knot like it's just any old thing to fuck but dear for you he is a bit to big for you."

Petra looks a little pained, at having to consider getting of you and she looks at her mother and asks her " Since I can' take him fully in the front do you think my chances on the back might be any better mother."

Molly lets out a gasps and then says " Did my dear little pup just suggest she wanted a huge dick up her pooper?"

Petra just nods her head and says " It's that mother or I try to take the rest of this and pray it does not hurt me."

You turn to Molly and ask " If she gets pregnant, will Petra still grow to full size?"

Molly thinks about it a moment and then nods and says " It would not be to much of a problem."

You look up at Petra and say " Little dear sweet little Petra, are you sure you want to do this one way or another?"

Petra looks into your eye's and nods and just as quite as she can says " I want to finish what we started even if we did not mean to start it now."

You just nod and think about the issue a moment deep in your mind you consider the issue of the size of your dick and Petra who is still on it. You decided to tell Petra " Please Petra, I want you to take as much of my Dick as you can into you. When you can't take any more tell me, that includes with help from your mother pushing down so long as it gives you or me no pain."

Molly nods and Petra nods and she just relaxes and waits for your dick to grow some more, becoming impatient she starts to move up and down your dick. And your cock hardens much faster and grows longer quickly as she moves up and down your dick. Petra looks down and notices, there is still space for your dick to go so she pushes down. Deep inside of Petra, she feels something give and a huge amount of your cock goes slamming into her cervix. You both groan in pain.

You then suggest " I guess, the first time with an Animorph requires a bit more **** then normal? Might I suggest no one told me this?"

Molly goes over to Petra and hugs her and then she slaps you on the shoulder, and says " It looks like there is still a good 6 inches that can't fit Alex."

Petra nods and is kinda of strange to look at as she is above you, on her knees, mind you her tail is wagging back and forth even thou she just experienced pain. You start to wonder if its a dog thing, sure Petra is not really a dog but you get the idea. You consider the issue again and let out a howl it's not a loud howl its not even a strong howl. But shortly after letting it out your dick swells up and and seems to shorten a little bit. You think about it a second, and then howl again and you gain another inch or so. You seem to be snug in Petra's cunt not super tight just tight. Your dick is just long enough to reach and touch all of the inside of her cunt. Petra lets out a moan as she feels this all happening and your balls seem to swell a lot as well.

Petra looks down at you and huskily says " You just asked for your dick to fix, dear god for her to enjoy this let it fit. Please make it fit, make it just for her just this once just for now." Petra lets out a moan, and Kamrin finally finishes eating and bothers to check on the three of you.

Kamrin says " Can't a lady eat in quite?" as she comes over to inspected what is going on, she lets out a gasp as she realizes or thinks she notices that your dick fits in Petra. She then looks at Molly who is not at all surprised by what she sees, and then down at you with a small little smile on your muzzle.

You turn to Molly and ask " You sure this is ok dear?" Molly nods and Petra starts to move up and down your dick, she gets to it with the pent up frustration she has. For the last two days she has tried to get you to do this to her, and finally by accident the adults decided to let her have what she wants. Petra finds this odd but is not one to deny that it feels every good. She leans back, on her arms exposing the spot were you connect to her in the deepest place possible so to speak. As she slims back and forth across it's length, she feels as if she is on a cloud. And just before she is about to cum she is **** to stop when she realizes your knot has finally swelled at the base of your cock on her down stroke and froze her in place.

Petra looks panicked for a second as she tries to figure out how to make herself cum well stuck like this, the experience is so new she has trouble thinking. You take pity on her, and reach your muzzle down to her crotch as you had her mother the first time. And start to lick at were your knot meets her nut and on up. When you hit her clit she starts to shake and spasm, and you feel your balls swell bigger. As she tightens her grip on your dick as she cums. Kamrin and Molly look on with a bit of pride, and they honestly feel happy for her even thou it was a bit of an accident.

As Petra comes down from her cum, her mother says " I guess the little pups tail wagging and tight ass against your crotch became to much for you Alex?"

You shrug and say " I did not even notice it happening til after she had adjusted to try and get it between us."

Petra lets out a moan as she ties to talk, but she is **** to only shake some more as you keep licking her between the legs after you finish answering Molly. She tries hard to say something but all Petra can muster is a howl. She tries again to put something into words and again all that comes out is a howl.

Molly looks at her little pup and places her arms around her and holds her, she even kisses her a few times on the forehead. To make sure physically and emotionally she understands, she holds her pup as she comes down from another cum. As Petra stops shaking you finally feel the tightness in your own dick as the bells tighten to get ready to do there job. moments later, Petra is shaking yet again from the feeling she is experience as you cum into her. Petra shakes a bit, excitement and pleasure. She personally has no idea were the volume of cum is going to go considering how well you feel her up. Thou for some strange reason for the second time today, you pass out. With the little pup on top of you.

You wake up a short time later to find Petra still riding you, it seems Molly is not to unhappy considering everyone else has the chance to get some of you. Thou it seems kinda strange to see the little pup grinding against your knot instead of penetrating past it. You start to wonder how that worked out well, you were out. You imagine for a moment that maybe as your dick returned to it's normal length maybe the little pup suffered a bit of pain and some humiliation. As the extra length on your dick **** the knot out of her tight little cunt stretching it past all reasonable possibilities. You look down to find your crotch is covered both in cum and Petra's girl juice so it does not seem to unreasonable that you might draw this conclusion. Petra slowly grinds against you til your body once again release, wolfish swimmers into Petra's receptive fish tank. You soon start to fall back to sleep again only to notice the feel of Molly and Kamrin helping clean up the wet spot and you and Petra with there tongues as you fall back to sleep.
