Your fluffy emotions flew away when a pained expression crossed your girlfriend's face.
"Are you alright?" You asked.
Instead of replying, Alice (your girlfriend) responded by reaching under her shirt and unclasping her very strained bra. Alice gasped a pained sigh of relief. Now, that her boobs were free from the confines of her bra, you could see how big and perky her breasts had become.
You stepped closer to Alice. You bigger figure stood over hers. You reached down and grabbed the hem of her top. Slowly, you pulled it up and over your girlfriend's head. She stared at you, transfixed by fear and love. With Alice breasts held in full view, you could clearly see them growing. The growth was nearly imperceivable.
"Hold me," Alice murmured.
Then, her breasts expanded explosively. Flesh flowed out of her boobs in every direction. Her knees buckled under the strain. You grabbed her as she fell. But, you hasty grip failed as more weight was conjured from thin air. Alice fell on top of her breasts which had grow so large as to be comparable to microwaves in size.
You firmly held Alice's hand is yours. She stared up at you with tears sparkling in her eyes. "What’s happening to me?" she wailed.
