Finish inside Caitlyn

With a last thrust, you can't hold it in any longer. The release comes like a flood. You finish deep inside her, buried in her pussy, pumping her full of your Chosen alien cum - far more than most humans would produce. Your orgasm lasts nearly a full minute, genetically modified cum pouring out of you deep inside her, designed to bypass any birth control and reach her womb instantly.

"Fuck," you say, emptying yourself inside her.

"Holy shit," she says. She doesn't seem annoyed, though - a win. You've been taught that sometimes, even if everything hints to the contrary, human women won't always appreciate you finishing inside.

"You must be really turned on," she says. "That felt like so much."

"It's not over," you say, before fucking her deeply once more. She laughs and then moans, loud. It only takes a few pumps and you're going again, flooding her pussy with cum. Zaydon (your handler) told you - your body can orgasm a few times in quick succession. Even with your specially-designed cum, still best to be safe - you want to fill her up as much as possible.

"Oh my god, what the fuck?" she laughs. "You're out of control!"

"If only you knew," you say, kissing her again as you finish coming. You make out for several minutes, dick still hard inside her, her pussy warm and inviting. You make sure she's feeling good - plenty of kissing, touching her clit, feeling her body, making her feel sexy, desired. With Chosen cum, there's a strong emotional component - any regret would greatly reduce your chances of impregnating her.

Eventually, you pull out, watching with pride as thick globules of cum leak out of her.

"You look so hot right now," you say.

"What, filled with cum? I'll have you know, I'm a classy lady," she laughs.

"I'd love for you to go out to one of your college parties with my cum leaking down your legs."

"Holy fuck," she says. "You're insane. Not gonna lie though that is incredibly hot. Fuck."

You push her legs up above her head, making her laugh again.

"What, trying to get me pregnant? I am on birth control you know. Otherwise I wouldn't have let you -"

"I don't care," you say. "I'm making you mine."

She sighs and smiles, eyes fluttering. She's fully in your grasp now.

"You know what? I hope you are pregnant," you say. "Or I'm just going to have to keep filling you up."

"Damn... it's a hot fantasy, for sure."

You make out for several more minutes, before she suddenly pulls away, eyes twinkling.

"Hold on, hold on," she says, laughing. "The AC is definitely on. You horndog!"

"Sue me," you say, laughing right back. "It's not easy to come up with a good excuse, okay?"

"Oh my god, you're too much. Shut up and kiss me some more."

You oblige.
