"Ohhhh, God," Astrid moans at the sound of your dominant growl. "Fooox..."
She bites her lip, hesitant to beg for a stranger's seed. But her former fears seem distant and foolish in light of the torturous pleasure of her need. She's a vixen in heat, and the scent and sound of a strong, confident male are the most delicious enticements she's ever felt. She glances briefly at Todd, but he's still trying to fight against this. She shudders, feeling the power of the moon, of her own desirable flesh. Todd is a fool for not appreciating this.
She shifts her hindquarters, so that her butt is aimed directly at you, her tail flagged to the side to display the dripping, black-lipped vagina between her thighs. "Please... I can't wait... take me, finish making me a vixen...!"
"Oh?" You grin, drinking in the sight of the voluptuous female pleading for you. Down to all fours you go, thrusting your wet black nose between her folds, the cold touch making her yip and shiver before grinding back desperately on your muzzle. Chuckling, you lap playfully at her swollen lips, savouring the flavour as well as the fragrance of your first vixen.
"Oh noooooo!" she groans, her flower clenching. "P-please no more! Just f-fuck me!"
"Oh Astrid," you half-sigh, half-growl; your own head turned by her arousal, groin pulsing in need to be sheathed in this beautiful passage. "I'll make you mine!"
You leap forward, torso coming down overtop hers, your shaft sliding along her outer lips to nestle between them, pre-cum dripping from the tip onto the grass below. You adjust your stance, reaching around to play with her breasts as you nibble on her ear and whisper.
"So beautiful... So needy..." You let your cock throb at her gates for a second, just enjoying the feeling of her shuddering under you in passionate submission. Then you pull your hips back, letting your cock spring erect again to point at her drooling entrance. "Ready to be bred, Astrid?"
"Y-yeee-iiiiiip!" Before she can finish the word you push in with delicious slowness, causing her voice to rise in shrill vulpinity.
"A... Astrid..." Todd blinks, squeezing out tears of pain -- and frustration at seeing his girlfriend choose you over him. Yet at the same time, he cannot help but admire you -- both of you; svelte todd and sexy vixen, and feel that... maybe you were right. Astrid deserves a real todd, who can take her like a fox should...
He shakes his head. What am I thinking!? But something begins to shift inside him as he watches you take his girlfriend. His groin throbs; and tingling spreading up his chest, the white fur washing over it, as eight points of pleasure form in his nipples and down across his torso. He is distracted by this by his cock hardening in his hand, almost painfully, and the need to stroke it...
To get ready for...
For...
The thought tickles at the back of his mind, but he refuses to acknowledge it, even though he's locked on the point of coitus, mesmerised by the glimpses he can get of your knot and swinging balls as they bump and grind into his girlfriend.
Or rather, your vixen. You've shifted one hand to her hip, to strengthen the force of your fucking, while the nimble fingers of your other continue to pleasure the nipples on her lower breasts and her clit. Since she is unable to do so -- main breasts squished into the earth, it's all her hands can do to brace herself beneath your weight and take your thrusts.
"Oh God -- Astrid --" you pant over her whimpers of delight "-- Ah! Ha! You feel -- so good -- so right beneath me!" You growl and nip at her ear, bursting with the feeling of your knot pressed tight and rubbing at her outer lips.
"Nnnn," she whimpers, pressing back, her passage jerking around your length speared into her. "Please... f-faster... I need -- need to be a vixen!"
You yip in satisfaction as you grant her request, then find your human voice again to call to your audience. "Watching -- Todd? Enjoying -- nature?" You know he is, and the voyeurism is an extra spice to the delight of yourself and your mate; both of you relishing the wild freedom of being able to rut before another's eyes.
And Todd's eyes are wide, fully captivated by your prowess. The memory of your cock, glistening in moonlit pre, dominates his thoughts. Your balls, slapping against Astrid's thighs, fill his vision. You are so potent. So... so male. Virile. He continues to masturbate, but it's your rod he's imagining.
"Fox..." he murmurs, eyes almost glazing as your maleness consumes his mind. The pleasure across his torso explodes, and his hips jerk against his hand, a strangely thick glob of pre bursting from his penis, bringing him back to his senses. "Wh-wha...?"
He looks down at himself, and cold fear returns as he sees his nipples have gotten much bigger... and much more numerous.
"N-no... oh please..." Yet he cannot help but bring his free hand to feel the sensitive, erect nubs of flesh, moaning in pleasure and agonised denial. "Noooo..."
Your ears swivel to his voice, a thread of curiosity weaving through your thoughts. But your passion has reached fever pitch, and while you do glance over to see the dark red areolae blooming across Todd's chest and belly, you don't really register it -- yet. It just drives you even crazier about the tits of the vixen you've currently mounted. You squeeze one, claws digging lightly into the soft flesh, as you feel your climax coming.
"Clossse..." you hiss between your fangs into your lover's ear. "So -- close! -- to claiming you!"
"Ye-he-he-heeesss!"
Both of you put all your strength into one last thrust, eager to consummate Astrid's vixenhood and position as your first mate. And both of you scream in joint orgasm as your knot swells and her new vaginal ring clamps around it, sealing in the gushing seed as you spurt time after time into the vixen's greedily clenching passage.
Lust sated -- for now -- the pair of you relax. You tenderly licking your mate's head and neck while she lays flat beneath you, tongue lolling in bliss. But, as you come down from your high, the image of Todd and his new accoutrements return, and you lift your muzzle to inspect the former human more closely.
"My, my," you say, coyly. "It's looks like I might have another vixen to claim soon." Your cock throbs again inside Astrid, spurting out a little more seed in anticipation.
"Mmm?" Astrid moans a little, pleased at the feel of you inside her, but also curious. She lifts her head and looks at Todd, and a foxy smile to match your own splits her lips.
Todd's transformation has progressed quite a bit despite his attempts to resist. His pelt is now fully grown in, his tail is now a foot long, and his nose and mouth have drawn out and fused into the start of his muzzle. But that isn't what you are really looking at; rather at the small mounds on his upper chest. And how he now desperately uses both hands to tug and tease at her males, as if to hold it in place.
And that is exactly what he's doing. Todd can feel his maleness slipping away from him -- both literally and figuratively. His pectorals are now completely lost, his breasts having expanded at least two cup sizes when he watched you and Astrid climax together. Vixenish thoughts nibble at his mind: how it would feel to have your weight pressing him down; to have your dexterous black-furred hands soothe the ache of his nipples for attention; how to take your knot inside and be filled with your seed,
But, he tells himself, that isn't what he wants! So even as he feels his penis shrinking, he concentrates on it, trying to remind himself that he is a male. If he can just rub out an orgasm, his fevered mind thinks, he can still remain male. Before it's too late.
Before...
"Ahhhh..." You pull out of Astrid with a pop and a long wet shliiiick. Just in time, because your pride at having turned this human male into a vixen just by fucking in front of him is quickly making your knot swell again.
"Haha... ha..." You wrap your hand around your maleness, enjoying the slickness of cum against your pads. "It looks like you reallyenjoyed the show, 'Todd.' So -- eager -- for your own share of this, hm?" You laugh as you massage your erection, dominant desire burning in your moonlit eyes. "Ah-haaaa! No... there's only room for one todd in this forest... What shall we call you, my needy little vixen?"
"Tanith," offered Astrid, now reclining on her side, laughing silently at Todd's frantic attempts to climax before you reach him.
"A-Astrid..." he protests weakly, eyes fixed on your large, pointed red dick. He licks his lips, mouth dry, stomach fluttering, then forces his eyes closed. I can do this! He shouts at himself. I'm a man!
"I -- I'm a man!" His voice wavers, though. You shake your head in amusement.
