Tuesday, October 19
She drove home to get her breast pump so she could drain herself in between the four classes she had that day. She knew it would be a test of willpower to focus, as Wednesdays were typically her hardest days. Unfortunately, sexual encounters with both Kim and Derek were fresh on her mind. It was warm today, but she was really looking for something that wouldn’t be so obvious she wasn’t wearing a bra, so she threw on a somewhat thin marigold-colored sweater and black leggings, stuffing paper towels in her purse for when she inevitably sprung a leak. She would shop for bigger bras afterwards. It was time to get back on track with her classes, and she was prepared.
She had a sudden realization when opened her chatroom app and remembered her post she’d made last week, the night before the ill-fated psychology test. She saw several mentions as well as dozens of reactions, responses, and friend requests. Her loins felt hot once more as she read through the responses to her laying on her back, filled and covered with cum.
“Oh shit”
“is that you”
“Name?”
“Damn, pregnancy was good to you”
“how many guys came on you”
Most of the DM requests were a sea of “hey”s and “hru”s with other unsavory messages peppered in. She decided not to respond to any of them, and just posted the picture Derek had taken last night. In the picture, her hair was messed up, hands cuffed to the bedframe, and her right cheek was pressed against the mattress, eyes closed, passed out in postcoital rest, the corner of her ruby lips curled up ever-so-slightly in a smile. The picture was from Derek’s perspective, and you could see part of his stomach, with the majority of his cock buried into her, Charlotte on her elbows and knees. The most obvious part, however, was the gargantuan load he’d shot into her, to say the least. Her belly had stretched so far it had reached the bed, with the sides of it visible around her back. About three feet in diameter, she guessed. Charlotte was dripping wet as she posted it, with one simple accompanying message.
“Yes, this is me.”
She realized how horny she was getting and rushed into the bathroom and splashed cold water on her face. Damn, I look good, she thought. Her face was practically glowing, and her lips looked full and firm, even more than usual. Her sweater hugged her breasts, the size of overfilled grapefruits. It was 11:52, and it took her at least 10 minutes to get to class, depending on the bus schedule. She knew she could get off quickly and it would help her focus better, so she pulled the breast pump out of her purse and slipped it on under her sweater and laid down. It was much harder without her vibrator, so she pulled up the picture of her and Derek she’d posted into the chatroom and began to respond to comments, explaining to incredulous users that it was real. She didn’t blame them for not believing. She felt the warm sensation in her chest that always heralded milk production as she chatted with people who were looking at her compromised state.
She checked the time. It was 12:05. Shoot. She had to leave now. But people kept commenting, and she kept responding. The milk cups were getting full, too. She was getting so close to orgasm, but she didn’t want to deal with them spilling all over her bed. Impulsively, she pulled them off, opened the emptying port, and drank one, reattaching it to her nipple, doing the same for the other. It was about 10 ounces of milk – a fraction of what Kim had drank earlier. She’d tasted it before, but never actually drank any significant amount of it. It was warm. Sweet. Creamy. Rich. It tasted great. It felt great.
The growth was subtle, but she felt the slow build of pressure in her shorts. Her pelvis rose slightly off the bed as her butt plumped up, and her thighs pressed against the fabric of her leggings ever-so-slightly more, maybe an inch bigger in diameter. Her pussy throbbed harder. This is impossible, she thought to herself, to be growing by the second. It was no wonder Kim reacted the way she did.
She held her breath to still the movement of her chest, holding perfectly still, and she saw her breasts rising steadily like water balloons under the almond-shaped pump cups. It took a minute or so as she massaged her clit with her hand, but they were about 20% bigger than the largest they’d been earlier, and the surging milk only made them swell more. Without thinking, she got up and went to the fridge, opened the mason jar of milk and downed it. Just a little bit more to catch up to Kim, she thought to herself, smiling. She couldn’t help but feel she was playing with fire.
She went to the bathroom, lifted up her sweater and exposed her chest, snapping a few selfies as her breasts settled at their new size: an inch or so larger than they’d been moments prior. She included most of her body, but cropped out everything above her lips. Unlike Kim, her stomach stayed as flat as a board, giving her quite the exaggerated hourglass look. She posted the cutest one to the chatroom and accompanied it with a message.
“Anyone want to see more?”
Immediately more messages began to flood in.
“Those are some yummy tits”
“Lactating too? You’re literally perfect”
“I want to see more of that ass”
“I want videos.”
“Get your boyfriend and make another belly photoshop”
“I don’t even care if your tits are fake, you’re hot as hell. Can I message you?”
Charlotte bit her lip. She was used to people staring since she maintained a good figure, and she had always figured some of it was probably sexually-motivated. But here she was, not only loving it, but encouraging it. She wondered how many people in public would think she had implants, given her impossible figure. And she hated that that turned her on even more — that people would think she’s such a horny, self-objectifying girl that she’d get huge silicone boobs and show off to guys.
Not wanting to disappoint anyone, she turned around and took a photo of her butt in the mirror. Looking at it, she was shocked that the photo she’d just taken was her own body. Her ass had gotten not just thick, but certifiably fat. Her hips were wider, giving her the figure that could pull off a Jessica Rabbit cosplay (with even thicker thighs, to boot) with just the addition of a sparkly dress. Despite her shorts being made of stretchy denim, you could tell from the picture how tight they were. There was not a single wrinkle on the fabric, and her thighs bulged out around the hem. She was afraid they’d go the way of Kim’s if she got much bigger — and these were her loosest pair.
She posted this photo, then headed back to her bedroom to take care of herself finally. Or at least, she tried, stopping on the couch from the stiffness of her shorts. Was she really still growing? She took small steps to her seat and flopped onto her back on the couch, attempting to shove her hand down her panties again, but her shorts were so tight, she wasn’t able to make it work comfortably.
She tried to take off her shorts, but she pushed with all her might and it just pulled against her swelling cheeks and hips. A moment of indecision — she was going to have to cut herself out of these shorts if she couldn’t slide them off. But why, oh why, did that make her so turned on? She pulled up her yellow sweater and grabbed both of her tits. A stream of milk covered her stomach.
