Kate
I rolled over in my bed and stretched, before sitting up. I yawned and got up from the bed. Looking out from window I noticed that the sun was already high in the sky. I must have slept longer than I usually do. I should go check on how's Jenny doing. I quickly dressed and went to her room. "Jenny?" I knocked on her door. No response. I slowly opened the door peeking inside, only to see that she wasn't inside. The dress she wore yesterday was lying on the bed, underneath some smaller piece of garment. What could that be? I wasn't very keen to violate Jenny's privacy, but the curiosity overcame the better part of me. Oh, it's a girdle! So that's why she looked thinner. Looking at Jenny's bed I realized that it didn't seemed as if she used it tonight. Oh god, I hope she didn't do anything stupid...
Walking down the stairs I already had a clear picture of what should I expect. The reality surpassed that image by a mile. Jenny, only in her underwear, was lying on the couch, snoring loudly, with her bloated gut covered in chocolate. The big white box was empty on the ground. I should have seen this coming... I put my hand on her shoulder shaking her slightly. "Jenny, wake up."
"Wha-" She exclaimed sleepily, while opening her large eyes. Her face contorted in pain and discomfort and her hands fell upon her distended abdomen and started to rub it. "Ouch, it hurts! I hoped it was only a dream..."
"I'm sorry."
"It's not your fault."
"I know, but still... I should have expected this."
"It hurts so badly." Jenny stopped rubbing her belly and raised her arms. "Could you help me up? I feel like a beached whale."
I was surprised at how calmly she acted. Truth to be told, I was a bit surprised at how calmly did I take it. I guess we're both getting kinda used to it by now. "Sure." I grasped her hands and pulled with all my strength. Fortunately it was enough.
"Thanks."
"So... no gym for today, huh?"
"Hell no! I'm gonna get showered and then I'll focus on digesting." Jenny stated matter of factly, patting her bloated gut.
"Alright, I think I'm gonna hit the gym by myself." I don't even know why I want to go to the gym. Oh well, it won't hurt me. Maybe I could call Mark to join me.
"Oh hey, can you tell Angie I'm not coming, if you'll see her there of course."
"Sure."
Jenny turned around and started waddling away and I just couldn't take my eyes of her backside, as it was swaying and quivering with each and every step. It looks like if her ass got bigger overnight. Jenny's panties were clearly a bit too small for the size of her ass and they were getting eaten by her butt crack. I've also noticed that her thighs rubbed against each other a lot. I found it strangely alluring. What are you thinking Kate? I shook my head to get rid of inappropriate thoughts like this. I looked over my shoulder. I should work more on my butt. I pulled out my phone and dialed Mark.
"Hi Kate, what's up?"
"Hey Mark, I'm going to the gym right now and I was wondering if you wouldn't like to join me?"
"Sorry, I'm working right now, but perhaps we could meet later and go for a lunch?"
"It's a date then."
I arrived at the gym and without wasting any time I found my way into the locker room. As usually there wasn't another soul in there. I stripped out of my jeans and put on yoga pants instead. Then I took off the tank top I was wearing and unclasped my bra, letting my fleshy orbs jiggling freely. At the exact same moment the door to the locker room opened. I was taken aback a bit because I wasn't used to people coming in here. I quickly turned around, heavy bosom swaying from side to side. It was Jenny's friend, Angie. She seemed to be dumbfounded, staring at my breasts with her mouth wide open.
