Cut to the following morning, after Lana's had a chance to process all that goo

Isaac had, of course, made sure to check in on Lana while her body processed everything. It was evening before she was able to get up out of bed again. She was a different woman now. So was Isaac. Both had let their lust and desire get the better of them and now, things had changed. Mostly Lana.

Lana waddled out of her bedroom with the menagerie of plates and cups Isaac had brought snacks and water in for her throughout the day. She was a sight to behold, no longer the lithe woman of this morning. She seemed almost as wide as she was tall. Her face was softer, her huge breasts hung down to her hips, wider than her shoulders and constantly dribbling milk in tiny rivulets. Her belly pushed them apart, two rolls sitting heavy over her now huge pussy, which caused her waddle to be even more exaggerated, the giant lips a teasing reminder of what it took to take Isaac in. Her fat hips sat a bit wider than her boobs, and tree trunk thighs fought for space against her pelvis, leading down to thick cankles. Isaac watched his handywork waddle on to deposit her items in the kitchen then come over and slump down on the couch, taking up the space of two people.

"So" Lana said, taking a few breathes, "This is... a lot." she stared blankly ahead. Her boobs covered her entire lap.

"Yea." Isaac replied, trying to ignore his growing erection incase this was going to be a serious talk.

"Yea. I did enjoy the sex, I don't regret that. But, I'm twice or maybe thrice the woman I was. This isn't normal."

"Nothing about this was normal in the first place." Isaac said stifly

"Right, sorry, you're a victim of whatever caused this too." Lana looked him in the eyes, "We should see a doctor, or something."

"Probably. If we can get dressed, they don't do house calls anymore."

"Yea." Lana breathed a little shakily, "I'm probably pregnant."

"A-are you sure? It's still the same day." Isaac stammered

"Isaac, you don't just fill someone like you did me," she paused. Aroused? Shaken? Afraid? Containing Excitement? "and not impregnate them. I don't see how it's possible not too."

"Okay," Isaac responded, now shaken himself a bit. "I can, uh, go to the store and get some stuff for you, if you want."

"I don't want you to go to the store for me, I need you to." Lana replied, running her hands over some of the soft new flesh she had acquired that day, "Some pregnancy tests would be a good start. And a really long measuring tape, I'll need to get sizes for new clothes."

"Alright, do you want me to get anything else, like some snacks or something?"

"Just because I'm fat now doesn't mean I'm hungry all the time." Lana let the statement sit for a moment, "But yes," she chuckled to herself, "I'd really love chips. Something about the saltiness, just really love it."

Isaac just blushed in response as he went to his room to get dressed. He mulled over the thoughts in his head as he tried to get dressed. She was so deadpan serious about the pregnant thing, but laughing and teasing about the snacks. Maybe she needed that levity? And the pregnancy was certainly a serious matter. Isaac shook his head as he pulled on that skirt. He could think about that more after she had taken the tests. His phone buzzed, he picked it up, it was a text from Lana

"And please get a couple breast pumps while you're there, leaking milk everywhere isn't nearly as hot as I thought it'd be. You can use my card."

Isaac finished getting dressed and headed out, picking up the card from Lana.
