She starts growing from all that milk she just drank!

Alyssa finally struggled her way to her feet, she stood and looked down at herself, her belly bulged out between her massive breasts. Her hands rose and rubbed her overfull belly, which felt nice. She let a small sound that sounded like a whimper and a moan.

"I can't believe how much you drank." Angela mused from the bed hazily, still catching her own breath

"Yea... I hope it was worth it." Alyssa replied, letting out a small hiccup. She sighed. She had never been so full before, she was amazed at how firm her belly was given her size, maybe that was another part of whatever was going on? Her belly gurgled and she started to feel... tingly? Her breathing quickened slightly, her hands sliding up and down where they could reach to see if she could feel whatever was going on. She cursed her restricted view, she couldn't see her feet anymore.

"Are you..? Holy Shit, you're getting fatter!" Angela said with more excitement than Alyssa would've liked. Alyssa was suddenly aware of her body pushing against her hands. Her flabby upper arms gently lifting her hands away, her massive thighs pushing against each other. She swore she could feel herself getting heavier.

"I-- I am!" Alyssa said, she slowly turned towards Angela, "Wh-what should I do?"

"Enjoy it!" Angela responded, with a smile. Alyssa didn't respond to that, but she did gasp as she felt her breasts start to fill, and fill quickly. She saw them round out, filling like water balloons. She gingerly pressed them, moaned, and then tugged on her nipples, which she could barely reach now. She couldn't tell if she was shocked or surprised, but she was startled by the volume. Milk started pouring from her tits, more than Angela's flow had been. It dribbled loudly onto the floor, small puddles quickly growing at her feet as she grew and grew.

"I'm getting so big!" Alyssa stammered, in awe of how she was growing, if felt like it was slowing, but her udders were still in full production.

"And so milky!" Angela said, sitting on the edge of the bed. "Mind if I have some more? Looks like you have plenty to spare." she winked, reaching out and rubbing both of Alyssa's nipples. Neither woman could possibly know the effect the milk had had on Angela, then on Alyssa, and now what that would do to Angela this time.

"They f-feel so full, I think I need them to be emptier." Alyssa said, not entirely sure what she was thinking. "P-please, milk me!" Alyssa couldn't believe what she was saying.

"Only if you're a good cow, and good cows 'Moo!' when they need to be milked!" Angela chirped.

"This-- This isn't a game! Something is happening to me! To us!" Alyssa said.

"Moo or I won't help you." Angela said, keeping her sly smile.

"Moo." Alyssa replied. Angela latched onto to one teat, then somehow brought the other to her mouth. The feeling was even stronger than it had been in the kitchen not too long ago. Her legs were getting weak. Alyssa moved forward and Angela scooted back on the bed, further and further until Alyssa was straddling on top of her, breasts fully pressed down onto Angela as she drank and drank. How Angela was still breathing was lost to her as her entire head and shoulders were buried in boob. Alyssa couldn't help herself, she needed this. She needed to be emptied, even as she felt Angela's belly swell out against hers while.

The bed groaned ominously
