Having the egg right at the opening at the start of your work shift, so you have to hold the egg in so you can finally deliver the egg back home.
*Sorry folks it's gonna be a long one. I got a good writing flow and idea for this.*
I knew that going into work today was probably not the smartest idea, but I needed the money and had signed on for a double shift. I started early, driving to the bakery I worked at around 7:45am. A few months ago I had signed on to help a friend out with a science project for one of their classes at our local college, which ended up being something a lot more out of the ordinary than I had initially thought.
"Human egg incubation. But not like a human egg, you have plenty of those. I found these alien eggs on the black market and need a test subject to see if these are even real. Can you help me please?" And me, being weak when it came to them, said yes. It has been 4 months since we inserted one of the eggs into my womb, at the time it was as small as a pea. They were a light green color, slightly glowing. To a normal eye, you wouldn't notice any difference with me. But I could see the beginning of a bump forming, the slight distended look of where my womb is, looking like I had just a little too much to eat. The bump was firm if I pressed against it, and I could often feel the egg shift when I moved around. It had definitely grown, I'm unsure by how much but enough for me to feel it's weight at all times.
When I pulled into the staff parking lot, I felt a sudden shift in my womb, more intense than the usual movement. Running a hand across the tiny bump, I felt to make sure that nothing was breaking before heading into work. Greeting my co-worker Annie, I moved to grab my apron when I felt a twinge deep in my belly. Placing my hand against the bump again, I felt the egg shift in a harsher way than normal. Weird, but it's not gonna stop me from getting my job done, I thought to myself as I tied on my apron and began to open up the bakery.
It wasn't even an hour into open when I had to excuse myself for a bio break, quickly rushing to the bathroom as another wave of pain washed over me. As soon as I was in a stall I unbuttoned my pants and pulled them down enough to expose me stomach and underwear. Looking at my bump, I noticed it was a bit more pronounced and I could feel the egg shift again uncomfortably, holding back a groan at the feeling. But the pain wouldn't let up, a near wiggling feeling from how much the egg was shifting again the walls of my womb. Then it all came to a crest when I felt a pop like feeling, a small rush of what seems to be blue slime coming from between my legs and soaking my underwear.
"Oh, fuck me." I cursed under my breath as I grabbed some toilet paper to quickly wipe away what would be best described as my waters, really it was a mucus sac the egg had developed around itself to keep it safe. Once I was cleaned enough, I pulled my pants back up and quickly rushed to the break room to grab my phone, texting my friend that the egg was on its way. That's when it dawned on me, I had signed up for a double shift today. Realizing that I had to stall the birth of this egg as much as possible, I put back on my apron and walked back to the counter with determination: make it thought this shift without having this egg.
Not even halfway though my first shift, I realized that was easier said than done. The egg, which turns out was massive, had managed to fully get into my birth canal and weighing heavily on my hips. I was saving my groans until I was in the pantry or couldn't be heard over the espresso machines. The worst part though, is that I was so turned on by it. The hiding, the weight and feeling of the egg shifting lower and lower, and nobody else knew that I was using all my mental strength not to give in and push the massive egg out of me. Moving throughout the motions of making yet another caramel macchiato, I bent down to grab another carton of milk when the egg shot forward, resting just behind my lips. I let out a startled yelp at the feeling, Annie giving me a weird look at my sudden outburst. "Hit my head." Was all I said and she gave a nod of understanding before returning to the customer.
By 3pm, I was sweating, constantly denying my bodies cry to push practically every minute as I moved around the bakery. My confident walk had turned into a slow, almost waddle. It felt like there was a bowling ball between my legs, and with every step the feeling of the egg shifting right at my entrance was torture. But I couldn't push, not here and definitely not right before the after-school rush of students. Standing behind the counter taking orders, a regular walked up and began chatting about her annoying professor. I felt myself relax a bit, swinging into our normal conversation. Biggest mistake. Not even realizing, my body began pushing, feeling the sudden stretch of my hole making me whimper out in shock and pain. Without apologizing, I rushed to the bathroom and quickly undid my pants again, pulling my underwear down too. I could see the tiniest bit of hard, glowing green shell peaking between my lips. Running my fingers against it, I moaned out as I pushed it back in, my body protesting as I did. Once I felt safe enough, I returned to work, only for all the progress I had just undone to return, feeling my opening begin to spread again just a bit as the egg slowly shifted downward.
Finally, after two hours of feeling the egg ever so slowly stretch me open, I left work for the day and as quickly as I could rushed to my car. The second I sat down, the angle from the seat and my jeans pushed the egg back into me a bit, causing me to groan at the feeling. I pressed a hand to my throbbing cunt, feeling the slight outline of the egg though my pants. It wasn't crowning, but it was getting close. Driving home was almost as bad as working, the constant burning and subconscious pushing but the egg not being able to move due to my underwear and jeans.
I managed to get into my home with only a slight waddle, not being able to fully close me legs with the giant egg weighing between them. I didn't even try to get to my room, heading to the couch in the living room and striping off every article of clothing on my body. I pressed one hand over my pussy again, feeling the egg against my palm. It felt like it was tearing me open, at least the size of an ostrich egg, and hand more of a bumpy texture. I whimpered for hours as I squatted and tried to push the egg out of my cunt, playing with my clit to try and ease the slide out with arousal. Around 11pm, I finally got the egg to crown, crying out as it felt like I was being split open and simultaneously orgasming, managing to have the egg pop and slip free of my poor, overstretched cunt.
