Milo knocked on Vinny's apartment door before just letting herself in.
"Hey, Vinny, I'm here! Is everything OK?"
Vinny lived in a small downtown studio apartment in Town City, but in this case, real estate was so expensive that "small" did not mean "cheap". True to Vinny's sense of style, his home was decorated with the most modern style, sleek and elegant but not totally minimalist, lived in and full but not maximalist. Its most striking feature was the loft, which Milo had to walk into the living room to get a good look at. The loft was basically Vinny's bedroom, while the rest of the floor was the living room and kitchen.
"I'm OK, I'm just up here!"
Milo craned her neck to look up at the loft and saw Vinny peering over the railing at her, obscured by a wall of blankets poking through the railing.
Milo climbed the steep stairs up to the loft and placed her backpack on the floor while she took in what she saw.
Vinny had arranged a bunch of his blankets, pillows, and couch cushions into a rough circle taking up nearly the whole loft. Vinny was sitting leaning up against one edge the way one lounges in a hot tub, wearing nothing but a pair of casual gray sweatpants clearly outlining a lovely bulge.
"A... nest?" Milo inquired as she approached and plopped herself down in his lap.
"I know, right? I'm surprised too."
"Huh?"
"I just kind of got an urge to put this together. I couldn't do anything else until it was done..."
"Huh. Nesting behavior. Maybe from the vulture DNA?"
"That's all I can come up with, yeah. But, as soon as I felt satisfied with it..."
"...Yeah?"
Vinny grabbed her by her shoulders and pushed her down, grinding his cock against her hips.
"...I got really, really horny."
Milo cracked a smile.
"So you made a nest and then called your mate?"
"Well... I guess... if you put it like that... Uhhh..."
"Kinky. I like it. So is it time to breed already or what?"
Vinny smiled, relieved that Milo was into it too.
"Is it alright if I'm a little rough?"
"Go ahea- woah!"
Vinny, just as he warned, roughly flipped Milo over so she was laying on her stomach with her ass in the air. He already knew she liked to be manhandled in bed, but always asked first just in case. He pressed his fingers to her cunt through her clothes, stroking her for a few long, teasing moments before pulling her jeans and underwear down her thighs. Milo made herself comfortable on the cushion-nest and propped up her hips so Vinny had full access to whatever he wanted. She was so ready to be his fucktoy until this heat of his wore off.
Vinny started by putting his mouth around her pussy, sucking her clit and licking all around it, starting slow and gentle. Milo couldn't help but lean into his touch, her body turning to jelly and relaxing in the soft, safe nest while Vinny ravished her. He picked up speed and force as time went on, going from careful, deliberate movements and escalating to "dog trying to get the last bit of peanut butter out of the bottom of the jar" - sloppy, loud, and eager. Milo was tightly clutching the blanket nest and writhing around as much as she could while Vinny pushed his tongue deeper into her, fucking her with it, until he felt Milo gasp, twitch, and melt onto his face. Her front half collapsed forward, pushing her butt higher into the air where Vinny could see her clenching and twitching as she rode out her orgasm.
"How'd you come already?" Vinny asked, after allowing a few minutes for recovery.
"I had a feeling about what you were calling me for and spent the whole subway ride fantasizing about what you were gonna do when I got here, and this is somehow still hotter than anything I was imagining."
"...Nice."
"You should put your cock in me now. Oral's nice, but you still haven't bred me."
"Yes, sir!" Vinny sat up and slipped his fingers into Milo's ready and waiting cunt, checking to see if she was still ready enough to take him. Once he was sure, he pulled his sweats down - no underwear on underneath, of course - and his cock sprang out, already dripping with precum.
Milo trembled in anticipation as Vinny took his fingers out of her and lined up his dick, slowly but surely pushing it deep inside her. He was fucking her like an animal, acting more like he was breeding than if he was making love. And Milo was loving it. She could feel his cock, hard and hot, getting embedded inside her, prodding at her internal organs, and all she wanted was for it to get even deeper in her. Vinny was thrusting his hips, but not quite as much as he had before; he seemed mostly interested in getting his dick in her and keeping it there, maybe some sort of vestigial rivalry instinct from his animal DNA, like knotting in wolves: keep your cock in for as long as possible so your competitors can't steal your mate and to raise the chances of your sperm successfully fertilizing their eggs. No amount of conscious knowledge that Milo was a trans woman, and her surgically-produced pussy was a dead-end to nowhere, could've persuaded Vinny to pull out completely right now.
Milo was gripping the blankets with tight fists and started biting down on them, too. She loved the feeling of clenching her cunt and meeting the resistance of his cock, and was unable to think about doing anything but moving her hips back and forth juuust enough to really feel it all the way up in her.
Snapping out of his cocksoaking trance, Vinny realized he hadn't done anything but moan for at least a minute. Worried that Milo was getting bored, he started moving his hips back and forth as well, in sync with his mate as much as he could manage. Milo made a pleasured noise in response, burying her face into the blanket.
Getting into a rhythm, Vinny's thrusts gained more energy and momentum, his cock getting harder and hotter inside her before finally slamming into her and pumping a huge load into her.
Milo loudly moaned as she felt her stomach swell with his seed, unable to go anywhere but fill her up while he kept his cock inside her for several minutes more, both of them climaxing, clenching, and twitching together.
Vinny collapsed sideways next to Milo, pulling her down with him, staying "knotted" with her.
Milo pushed his dick a little further into her as she snuggled up against him.
