She doesn't like it

Brittany runs her hands on her body in panic. She feels her way around her enormous breasts and feels her stomach. "I thought you knew what you were doing", she barks at you. "Sure, the stomach is flatter, but these boobs are ridiculous! I want a mirror!" You find a half broken mirror in the storage room and hold it up for Brittany. "I look like one of those ridiculous porn stars!" She paces back and forth a couple of times, boiling with rage. "I'm getting out of here... No, wait, I can't even fucking leave this room, I won't fit in my clothes! What do I do? I'm literally fucked!"

"Umm, I could literally unfuck you...", you cut in.
"WHAT?"
"I could do it again... just cum on your boobs a second time and reduce them", you tell her.
"What... I don't know... what if you just make them worse!", Brittany shouts.
She seems to pause and looks at herself in the mirror. "I guess it could work", she says slowly, starting to calm down. "I actually kinda like what you did to my belly, if you ignore these hideous boobs. So I guess you actually can make things smaller, too."

Suddenly you see her smiling for the first time ever. "OK, Mr. Magic Dick, time to get to work then", she says and motions you over to her.

"Okay, but I need to...", you begin, pointing at your still limp cock. Instead of answering, Brittany grabs you by the neck and pushes your face into her enormous cleavage. Her other hand finds your cock and starts to tentatively stroke it. "I haven't met a dick I couldn't make hard twice in a row", she murmurs. Her words, the incredible feeling of her gigantic tits on your face and her skillful hands make your cock twitch back into life, slowly but surely.

She lifts you back up from her cleavage looks down to admire her handiwork. "Your dick is actually not that bad looking. Normally I would blow you, but I don't want to doing some crazy shit to my head", she ponders. "You'll need to settle on a tittyfuck", she says casually. You gaze at her enormous breasts. "Sure, I'll settle on fucking a cleavage that almost engulfed my head", you think to yourself, not able to suppress a stupid grin.

Brittany motions you to lay on a box in the storage rrom and kneels beside it. She seems to have some trouble at first adjusting to her new size as she aligns her massive cleavage on your cock. She soon gets the hang of it and grabs her enormous breasts and presses them around your erection. The feeling of warm, soft boob flesh surrounding your cock meat from all sides is amazing. She starts to move her boobs up and down around your cock, very slowly at first. She looks you in the eye and says "Remember, only smaller this time". You nod and moan in pleasure as she works her massive boobs on your cock. You are glad its only been minutes since you blew your first load, otherwise you couldn't have lasted even this long, given how amazing Brittany's gigantic tits feel. You have dreamed about a tittyfuck, but you had no idea what it would feel like.

Brittany notices you are not an easy nut to crack the second time around, so she starts picking up the pace and amplitude of her boob strokes. Her boobs start making a loud clapping noise as they land on your thighs again and again: CLOP CLOP CLOP CLOP...

This is too much for you and you feel another eruption of cum building up. You look at Brittany and try to picture her the way she was before your treatment, but it is hard because you are enjoying her current for a bit too much.
