Stretching Your Limits

You shift your grip on Tara so you cup her around her back, letting her arms and legs hang freely. The smile on her face is almost manic as you start to line her up with your cock. "I'm still worried I'll hurt you, but if this is what you want..." you say, trailing off for a second before adding, "And if I do start hurting you, quickly tap my wrist three times with your tail, okay?"

Tara nods eagerly, making you glad you can find some equivalent of a safe word just in case. But you have been delaying long enough and so you start to lower Tara down until the crown of your dick starts to press against the space between her legs. At first, it feels like you are pressing up against a wet hole that is far too small to fit your girth but then somehow Tara's pussy stretches wider than it should to allow you entrance. You are surprised at how easily you start to sink in after that, the feel of your fairy's inner walls somehow squeezing and rippling against more of your length than it seems like should be physically possible given how much of you there is compared to her body.

As you continue to pull her down, you begin to notice her stomach starting to stick out a little. You pause to observe the small bulge, working her back and forth an inch or two to see it swell and shrink in response to your movements. Now that you have confirmed that your cock is the cause, you start lowering her back down your manhood once again. Before your amazed eyes that bulge starts to grow larger, the outline of your dick becoming easier to make out in the process.

It looks like it should be painful and yet the only expression you can see on Tara's face is one of pure bliss as her gut is pushed outwards more and more. Yet somehow it still feels like your dick is enveloped totally by the walls of her pussy, the warm and wet flesh still rippling around your rod even though it looks like you are well past the point you would have gone beyond her cervix and into her womb.

You were so nervous about this at first but now you are surprised at how eager you are to see how it will both look and feel to be fully inside of her. You give her sides a little squeeze, Tara picks up on your unspoken warning and nods, braces herself, and you finally just yank her the rest of the way down, her crotch smacking against yours as you fully come together.

The feel is incredible as Tara starts to spasm wildly, not quite an orgasm but a sign of just how much she is feeling it too. Her movements cause her already clenching insides to ripple around your cock more intently, as if trying to milk you of your cum then and there. The sight is... erotically grotesque as her gut is stretched to the limit, the pillar of flesh that is warped by your dick, along with the head of that dick itself, is high enough that it reaches just over her lips and nose. When she actually nuzzles and kisses that bulge of flesh you can feel it through the barrier of skin and vaginal walls, a sensation no human could naturally replicate.

Your hand flexes when she kisses and you even accidentally let go of her for a second or two but she stays hanging on, held up completely (and yet still somehow safely) by your hook of flesh. Once you take hold of her again, you throw any hesitation to the wind and start to slide her up your cock again. Her belly shrinks back to its normal size as you withdraw everything but the very tip of your now quite lubricated penis and after she shivers at the sudden withdrawal, you jerk her back down again while simultaneously lifting your hips slightly to stretch her out again.

Now fully confident she can take it, you begin using her as a tool for jacking off in earnest. Though she makes no sound, the way her mouth hangs open and her tongue sticks out to lap at the underside of your cock's bulge with each inward motion shows you that you are doing the right thing. The endless pussy dimension it feels like your manhood is inside of also rewards your aggressive motions with intense squeezes and rippling of every inch of your rod.

You are not going to last much longer under such pressure and, given how much your dick is starting to tingle and your fairy is looking at you with "please cum in me" eyes, you see no reason to draw things out. Gritting your teeth, you hilt Tara on your manhood one final time and let out a long, hissing groan through gritted teeth as your length throbs and twitches while it fires off thick white strand after thick white strand of your seed.

Tara's entire body shakes and thrashes as you climax, her own orgasm hitting the second the first drop of your load is poured into her. Her eyes widen further as the size difference means your cum is voluminous enough that her belly starts to swell in a second direction as well. As you see it happening, you start to pull out as slowly as possible, letting her insides help you squeeze out every drop it can even as you make room for those drops to keep her full. By the time you withdraw completely, your dick is spent and not a single drop has escaped your little Dragon Fairy's now-big belly.

You lay her down on the sink's countertop, watching her catch her breath as she lightly rubs at her swollen lower torso with a dreamy look on her face. It is as if she is many months pregnant, just on the cusp of giving birth, and that image is only enhanced when the area just above her pussy starts to glow. When the light fades, you see a series of three small runes have been tattooed into her skin (which suspiciously form a shape not unlike a womb and ovaries when put together).

Wait, would she have the magical protections students did? Can humans actually impregnate fairies?!

Seeing the sudden concern on your face, Tara gives you a toothy grin as she shrinks back down to her original size, along with her stomach. The runes disappear from her body and you give her a stone-faced look as you see she is silently laughing at you. You suddenly remember from your emergency reading of Relations With Familiars tome that said female Familiars, if still under command of their Summoner, can only get pregnant whenever and with whoever that Summoner orders them to.

Since you're not ready to be a Faebydaddy quite yet, you have not giving that order this time so you should be safe. Still, you lightly rub her on the top of her head with your forefinger as punishment for her prank and she becomes more relaxed again. "Once I get cleaned up," you say as you catch your own breath, "we'll go get some breakfast."

Tara sits up and shakes her head, patting her stomach again and sitting back like someone who has just finished a heavy meal.

"Ah, I see," you say before chuckling, "Filled you up in more ways than one, did I?"

She nods more vigorously and licks her lips. It seems like she enjoyed that more than eating too.

A thought hits you. "Say, I can't promise I'll be in the mood every single morning but, if you want, I'm willing to put you on Morning Wood Patrol from now on."

Tara's expression lights up even more than it already was and she is nodding so hard that it is a wonder it does not fly off.

You smile before another thought hits you and add, "Though if Amelia agrees to sleeping over, she might want dibs. Or share. Or want to be the one to move you up and down."

Your Dragon Fairy gets up, re-summons the scales that give her a minimum of social modesty, flies up towards your face and rests her forehead against yours. You quickly get a few images of the actions with Amelia you described that give you the impression she would be okay with that... as well as a much more powerful and prominent image of a naked Harmony on your bed with a human-sized Tara. The fairy is embracing the busty blonde from behind, one hand clutching and teasing one of the human's breasts while the other is further down and spreading Harmony's pussy lips invitingly towards you while the tip of her tail pistons in and out of Harmony's asshole.

When she backs off, ending the sharing of thoughts, you smirk and give the top of her head another rub. "Should I take that as you rooting for or against Harmony in the duel?"

Tara just grins mysteriously.
