Huge

'Well, she did say to surprise her', you decide to write HUGE TITS on Stacey's cleavage, not exactly sure how big that was going to make them.

"Finn!" Stacey cries out as her chest expands inside of her flimsy bra and you hear a snap as the clasp at the back breaks as it fails to contain it's new weight. The material falls to the floor and yet your girlfriends tits still continue to grow.

C cup, D cup, E cup... Jesus! They must be at least G cup and still going!

"Oh, shit! Sorry babe!" You don't know if it will work but you hurriedly cross out HUGE and replace it with DD instead, causing Stacey's breasts to shrink back down to a still impressive, but more manageable double-D sizing. "I guess I should have been more specific."

"Oh, thank god! I thought my back was going to give out." Stacey stretches out, giving you a full look at her newly endowed chest. You were always happy with the size of Stacey's breasts but damn her new ones made your cock swell.

"Well, at least we know now that we can cross out anything that we write if needed." You scratch the back of your head sheepishly.

"Mmmm." Stacey agreed distractedly admiring her new set of tits, prodding them and jiggling them to test their weight.

"Fuck..." You utter without thinking at the sight in front of you.

"You like?" Stacey looks up at you, clearly enjoying the effect that she is having on you.

You just nod your head in affirmation and scoop up your girlfriend by her ass, pressing her soft new tits into your face.

"Hahahaha stop!" Stacey laughs as you jokingly motorboat her tits between your face.

"I just couldn't help myself. I just had to show my appreciation to the girls." You grin wolfishly, stealing a kiss from your slightly heavier than usual, girlfriend.

"What should we try next?" Stacey nibbles on your ear, becoming friskier and friskier.
