Note: Milly started morphing into a personality I didn't like, so if you're reading you'll experience something closer to my original vision. The path of least resistance is to read the pilot (prologue) at the bottom
Matthew was sitting on his couch and watching some television as he waited for his new roommate to show up. It wouldn't be long before she came, and he was eager to meet his new assistant mangaka and living partner. Her name was Milly MilkWater according to her texts, and she seemed really sweet based on the phone call they'd had. Matthew could only hope it would work out; he hated having to tell people that they were doing anything wrong.
Just as he was thinking about it, his doorbell rang, causing him to spring up and jog to the front hall.
"Who is it?" he asked.
"Oh, um, this is Milly!"
Matthew already thought she sounded cute, and he was already expecting her to be as well. When he opened the door, he immediately noticed that she was taller than him by an inch or so (which wasn't saying much, he was 5'4"). But his very next mental note was that she had boobs the size of beach balls hanging from her chest. Of course, it would be uber unprofessional to stare, so he did his best to be polite and inviting.
"Hi, I'm Matthew!" He held out his hand, and Milly sighed what seemed to be a pleasurous moan as she shook it.
"Oh, it's so nice to meet you Matthew. My name is Milly, but you already knew that, I suppose."
Her nipples were mere inches from his belly.
Matthew immediately said "Before anything else, I'm aware that I'm shorter than you expected, but please try to ignore it if—"
"Oh nonononono, it's okay!" Her reassurance came swiftly, and she put both hands on one of his 'it's time for a talk' style. "I don't care how tall you are, you're still really good-looking." Immediately realizing what she said, she added "Wait! I mean that you're perfectly fine, just normal is all!"
Matthew gave her a smile so she didn't feel bad about it, and spread his arms out. "It's fine. I'm a hugger, so if it's okay with you, hugs will probably be our main form of hello and goodbye from here on out." This was true, he was indeed a hugger, but he couldn't help but feel that there was a secondary reason he suddenly wanted to hug his new roommate.
Milly squealed quietly when Matthew finished his sentence, wrapping her arms inside his and squeezing him like a friend she hadn't seen in years. "Oh I love hugs! Anytime you want a hug, just ask and I'll give you all the snuggles and hugs you can ask for!"
As Matthew slid between her huge boobs, he could already tell that this arrangement would work out incredibly.
They unloaded and unpacked Milly's belongings in record time, and were eating dinner together an hour later. As Milly slurped down her noodles, Matthew used chopsticks to single each noodle out. Halfway through, however, he found himself lost in the motions of Milly's lips, watching as she slurped and sucked down her noodles with pleasure that was almost sexual and kind of weird. But intriguing.
She held the bowl up to her mouth and drank up the last bit of juices, putting the bowl back on the table when she finished. She patted her full belly and sighed.
"Thank you, Matthew. Those noodles were incredible."
"Oh, of course Milly. I actually enjoy cooking for my friends."
Milly looked up at him, hands still on her full belly. "F... Friends?"
Matthew shrugged. "I'd consider you a friend. Innocent until proven guilty in my opinion. Now, I'll do the dishes and we can talk about the—"
Milly immediately looked at Matthew and shook her head profusely. "Oh no, let me do them!" She hopped from her seat and took both bowls, which was not much but her gesture was very appreciated.
"—payment arrangements..." Matthew mumbled to himself as Milly passed by.
She heard him, and said, "Oh yeah... I know I said any amount to your offer, but I sincerely hope that you don't decide to take too much in the way of liberties on the price..."
Matthew leaned against the wall next to Milly, looking at the bowls as she washed them. "Actually, since you're already here and I've decided based on our interactions that your integrity and sweetness are far more incredible than I could have hoped for in a roommate, I will hinge the entire arrangement on your help with the manga series I create."
Milly smiled as if she thought it was a joke, but when she noticed he wasn't smiling back she gasped. "You mean it?!"
Matthew nodded. "Of course. The first volume alone pays the bills so far."
Milly squeeled and began hopping up and down quite tastefully, and Matthew smiled at her. "We'll talk it over tomorrow, if that's alright...?"
Milly grinned, and nodded agreeance. "Of course. I can't wait."
Matthew went to go and sit on the couch, but Milly stopped him. "Wait... M-Matthew... Can you do me a favor?"
Matthew nodded. "Of course, Milly, anything."
She smiled, closing her eyes and sighing in relief. "Will you rub my belly for me?" she asked as she dried her hands, walking with him toward the couch. "I think I ate too quickly and made my tummy hurt."
Matthew thought for a moment. Whether or not this was really happening was a question he was asking himself in his head.
"If you are really okay with anything, that is," Milly added. "I know it's... A little weird."
Matthew reluctantly shook his head. "N-no! I don't mind, I'll rub your belly for you."
She plopped down on the couch and huffed as she leaned back. "T-thank you, Matthew. I know it's w-weird..."
Matthew sat beside her and murmured "Over the shirt?"
Milly giggled, whispering back, "under, dummy!"
He nodded, sarcastically glad that he'd asked. He put his hands on her shoulders first so he didn't surprise her by putting his hands on her curvaceous hips immediately, and ran his hands down her back. Milly loosened up her muscles as Matthew reached under her shirt and began to massage at her sides which made her tingle all over. This was the final straw for Matthew: his life had prepared him not to pop a boner in these situations, but as he rubbed at her belly, the thought of going just a little bit higher crept into his mind and stayed rent free the entire time. Try as he might to push the thought from his mind, the feel of Milly's soft, smooth skin reminded him too much of boobs in his hands. He didn't get too ornate with his rubbing, but made sure that Milly was feeling great afterwards.
"Thanks Matthew. I feel so much better after that... Do you want some belly rubs?"
Would it be weird if he said yes?
...
Would it be weird if he said no?
"... Sure, if you'd like to give me one. I don't need it though."
She leaned back and patted her lap. "Everyone likes belly rubs, Mr. Matthew."
Matthew hesitated for a second, but still moved onto her legs, sitting up straight so he didn't lean on her boobs. Milly, however, wrapped her arms around him and pulled him back, right into her mountainous mounds of joy.
He leaned back against her expansive chest wordlessly, and relaxed as she ran her hands up his shirt and began to rub at his abs. Instead of commenting, she began to run her hands across his muscles, sighing and moaning to herself as she felt up his chest. She pushed her body against his a few times, but probably realized it was weird and stopped.
Much to Matthew's dismay, she addressed it. "S-sorry, Matthew. I didn't mean to get carried away..."
Matthew leaned his head back on her shoulder and smiled. "It's really fine. I hope that you're comfortable here, and I'll try to be the best roommate you can ask for."
Milly sighed, still rubbing, cross-armed, at Matthew's ab muscles. "Well, I'll try my best to be a good girl too. Thank you for the room."
They watched TV for another ten minutes or so, then Matthew mentioned going to bed, which Milly also agreed to do. Matthew went to his room and changed into pajamas before he lay down, beginning to drift off to sleep. Of course, less than two minutes later, Milly stood right next to the bed.
"U-um... I didn't have room to pack a bed... Can I sleep on the couch?"
Matthew thought for a second before he answered. "I wouldn't mind, but it's really uncomfortable to lay on. I'll let you sleep in my bed if you want."
"S-sure, if you want," Milly whispered.
Matthew rolled over and uncovered himself, ready to get out of bed so Milly could have it; Milly, however, nudged him back toward the matress. "W-we can share. I mean, if you want to. I wouldn't m-mind."
Matthew stared at her, but decided to go along with it. He lay back down as Milly went to the other side of the bed, lifting the covers and climbing under.
"I hear it's gonna get cold tonight, so I'll try not to take the covers," Matthew murmured, turning away from Milly and facing his cracked door.
"If it gets cold, I'll just have to hug you tight to keep you warm."
Matthew got a surprise when Milly moved closer to him and wrapped her arms around him, pulling him in close. He wanted his space, but something within him wanted the warmth of Milly's embrace just a little bit more. He wrapped his hands around hers, drifting off to sleep for the day.
