She wants that cock in her right now

“Will he... have sex with me?”

“Oh course!” says Katie. “He'll do it however you like: hard, gentle, simple, kinky, just tell him what you want.”

Jill finally looks you in the eyes. She looks horribly embarrassed, but too hopeful to let that stop her. “I... I... can't ask him for that!”

Shelly walks up to the large girl and pats her back reassuringly. “Oh, honey. He's a love ****! He's spent years preparing for this. He doesn't want you to ask him for anything. He wants you to command him! You don't want to ruin his fantasies, do you?”

Jill looks at her more confident friend for a moment. Then she looks back at you and very quietly says, “Fuck me.”

“Yes mistress!” you say, your voice dripping with devotion. You jump up and kiss her. Your cock twitches, painfully hard. Despite your real feelings for the girl, the recent wishes make it so you're horny anyway. You run your hands over her grotesque body.

“Um,” she mutters, “undress me first.”

“Yes, mistress!”

She pull off her billowy black clothes, trying not to look too closely at what you find beneath. When you're done, she bites her bottom lip and looks at Katie and Shelly. They wave her on, motioning for her to get on with it. She lowers herself to the floor and gets on all fours.

You position yourself behind her and find that her pussy is already completely wet. You rub your newly huge cock in her juices to lube it up. Even with the lubrication, you can't get it in on the first try.

“UNNNGGGHHH! Oh my god! He's going to split me in two!”

“Yeah, but you'll love it!” says Katie.

“Shove it in there, stud!” yells Shelly.

You drive your massive member into the virgin pussy. She lets out a high pitched squeal. You grab her fat folds and use them for leverage as you plow into her.

“OH GOD OH GOD OH GOD OH GOD OH GOD OH GOD,” repeats Jill endlessly.

You stare at the back of her head to avoid looking at her fat body. Your intense sexual need almost makes this pleasurable. When you hear the other girls laughing, you look at them and see them thrusting your hips to mock you. Their slim, tight bodies taunt you as you fuck the whale in front of you.

“What's happening!?” yells Jill. “It's so... it's sooo... it's so GOOOOD!!!”

She slaps the floor and clenches her pussy impossibly tight around your cock as she orgasms. She falls forward onto the floor, leaving your unsatisfied cock hanging in midair.

After breathing hard for a minute, she looks at you, but says to the girls, “Isn't he supposed to get small again?”

“Oh no,” says Katie, “love slaves don't get soft. And they can only cum when you give them permission to. It's the special training. That's how they ensure that they can always satisfy their mistresses.”

“You mean...” Another blush covers Jill's face. “He can do it again?”

The girls look at you and nod with evil grins. Shelly says, “He's going to do anything you want, any time you want, now and forever.”

Jill smiles like when she was a girl and saw all the presents Santa had left for her.
