Finally Convinced: Part 3, Loaned Out

Here I was, transformed into a pair of panties, stuffed into my girlfriend’s mouth. Lisa was sitting in her office chair in her own bedroom, her hands tied behind the backrest. Two days ago, Lisa convinced me to spend the day transformed into her panties. I didn't want to, but she had promised a threesome with her hot roommate Andrea if I did it for her.

So naturally, I agreed. She wore me during an extra-long and strenuous day at work, but forgot that I was her panties by the time she got home. After a trip through the washing machine, Andrea found me and put me on, thinking I was one of hers. Unfortunately for me, Andrea was a bit bigger in the hips and stretched me out even more than Lisa had. I was put through a tortuous run, followed by a chill day off where Andrea hung around for the day naked except for me.

At the club that night, a drunken Lisa finally came clean and told Andrea what happened. The next thing I knew, Andrea was fucking a random dude on Lisa’s bed, while still wearing me, and while a tied-up Lisa watched from the corner! Then Andrea stuffed me into Lisa’s mouth and went off to take a shower, instructing her not to take me out until she returned.

My body was so saturated from the day’s activities, creating a smell and taste cocktail that was confusing and overwhelming. I was stained with Lisa’s saliva as well as sweat and arousal from both Andrea and the man she fucked. I was even pulled slightly inside of her by his deep, strong thrusts, adding an additional stain to my fabric.

Being balled up inside Lisa’s mouth like this was a whole new kind of experience. During the two days I was worn, I became very familiar with the stretch and pinch of walking, running and other activities, but this was something different. I was awkwardly and uncomfortably folded over myself, twisting my body in ways that my mind couldn’t begin to untangle.

Apparently my body was big enough that it was uncomfortable to close her lips over me, leaving a small gap for me to see a bit through Lisa’s teeth. I almost wish I was in complete darkness, the small window of view felt like one of my eyes was closed and the other was half covered. I only saw enough to fully appreciate that I couldn’t see anything well enough to know what was going on.

But that was a couple hours ago. Now I lay on Andrea’s bed, splayed out like I was in a product photoshoot. Before Lisa was released, Andrea forced her to transfer my Transform-It app data to her phone, giving Andrea control of my changes. Then she instructed Lisa to put me through the wash and leave me on Andrea’s bed.

I lay there for a while, hearing the occasional voice from the hallway, but seeing nothing through the mostly-closed door. Eventually I heard a third woman’s voice, not Lisa or Andrea.

“Yeah, I have an extra one in here you can borrow, of course,” Andrea pushed the door open and walked in, shouting back over her shoulder. Currently she was wearing a pair of short-shorts and a loose hooded sweatshirt.

She looked down at me and winked, bringing her phone out and tapping away on it. She aimed the camera at me and pushed a button. The feeling of transforming came over me, just like on that first day when this nightmare started. It wasn’t as significant this time and didn’t last as long, though. When it was over, Andrea smiled and picked me up. Even though I could see out of any part of me, I was having trouble determining what I had become.

“Here it is, Molly,” Andrea called over her shoulder, lowering me to her side in one hand as she stepped back into the hallway. Folded as I was, it was hard to see, but I could tell that there was in fact a third woman that I had not met. Molly was wearing a loose sweatshirt, so it was hard to get a good look at her figure. Andrea lifted her hand up toward her, and Molly reached out and took hold of me.

“You can get changed in the bathroom down the hall,” Andrea said with a smile. I saw Lisa looking at me and then back to Andrea with a questioning look. Andrea smirked and nodded.

“Thanks! You sure it’ll fit?” the new woman asked.

“I mean it will be a bit snug, but it’s the best we got!” Andrea responded.

What? She chose to change me into something that was too small? What fresh hell is this?

“Thanks!” Molly said and headed off to the bathroom.

When we got in here, I was tossed onto the counter. From here I could see myself in the mirror. At first I thought I was a pair of gym shorts, but there were too many holes. I took a closer look and realized what Andrea turned me into. I was a sports bra!

Meanwhile, Molly had turned her back on me and pulled her sweatshirt off over her head, tossing it onto the ground. Now that she was just wearing a black bra, I could see her arms and shoulders clearly. Her arms bulged with muscle, though somehow, she still had a trim figure. When her hands reached behind her to pull her bra clamps apart, the muscles in her arms became that much more defined. She slid that off too and dropped it onto the sweat shirt. When she turned to me a chill ran through me.

Her tits were huge! Not overweight, ming you, but bigger than any I had ever seen in person. Molly reached out and lifted me over her head and pulled me down her arms. I settled over her shoulders while she shifted position, the stretch like nothing I felt before. It was similar to being stretched as a pair of panties, but different, like my body was resisting the pull. Molly took a firm hold of the bottom of my form and pulled down hard, stretching me out away from her body.

I groaned to myself, the stretching feeling becoming overwhelming. She lowered me down over her sizable chest and settled my bottom hem around her torso. It turned out that as a pair of panties I didn’t know the first thing about stretch. Her tits filled me, pressing on me harder than Lisa or Andrea’s ass had.

Despite the pain of being pulled so tight, I could now see myself clearly. My fabric was a deep green color, my shoulder straps sweeping in as they went down the chest, leaving the arm with full range of motion. While the neckline was high, there was a strategic gap in the center, providing a bit of a ‘window’ of sorts to Molly’s cleavage, which was substantial. Each of her sizable tits were contained in each cup of my body, which I was pulling subtly apart, giving a view of her torso between them. She gave an approving smile and nod, collected her clothes and stepped out of the bathroom. 

“Ooo, that looks good on you!” Andrea complimented Molly, who leaned into the praise and struck a pose. I noticed Lisa looking at us quietly. “Well if we’re gonna make it to my class, we gotta go!”

“Let’s do it! I’ve been looking for a way to work on my cardio that doesn’t suck!” Molly said, depositing her clothes into a nearby duffel bag and lifting it up over her shoulder.

Even the motion of leaning forward and standing up caused me discomfort. As her torso went horizontal, her tits hung straight down, changing the part of me that was forced to hold them up. It was like holding a weight straight out from my body instead of hugging it into my chest. And they were going to the gym? For one of Andrea’s classes no less!

The girls loaded up into Andrea’s car, each with their own duffel bags. I wasn’t thrilled about what was happening and what was going to happen, but at least like this I could see.

We arrived at the gym and wasted no time walking back to the glass-walled classroom, which already had six women inside, stretching and milling about. Looking around I realized that there were only women within line of sight. I didn’t realize that Andrea worked in a woman-only gym.

“Alright ladies, are you ready to get started?” Andrea asked the room in a teacher's voice as soon as the door was open.

The other women responded with a chorus of excited responses.

“Ladies, I have three guests today,” Andrea said, giving me a quick glance and smile. “Sorry, two guests! My roommate Lisa, and Molly in the green there. Molly lifts, but she doesn’t know the joys of our type of cardio, so she is joining us to learn all about it!”

Molly waved with a smile and as she and Lisa found a spot among the ladies.

“Alright, we are starting with a slow jog to get warmed up,” Andrea called, the rest of the women starting to follow her instructions.

From Molly’s first step it was agony. After the shock of being launched herself into the air, it was bliss, her heavy chest floated up and took all the weight off me. But then she landed, and all that weight hit me like a truck. For a split second I felt like I was going to rip apart, the already heavy flesh inside me feeling like it had at least doubled. I seriously thought I was going to split a seam with how hard it hit.

And all of that happened in a split second, then again, and again, and again. I screamed in my head, the agony of bouncing taking over everything, occupying every bit of processing power my brain had left. To make matters worse, my point of view was thrown around as well, the room turning into a haze of blurred motion.

Every second of this slow jog seemed worse than the one before it. Finally I heard Andrea address the room.

“Alright transition into a ‘squat pop-up,’ ladies!”

Molly slowed her jog, standing still for a second. The women around us squatted down slowly and then straightened up quickly, hopping a few inches into the air in one motion. On the second squat, Molly followed along. As she went down, panic gripped me, knowing what was coming. I tensed up as much as I could.

Molly straightened up quickly, pressing me down into the bra for a moment before launching herself into the air. The bliss of weightlessness was ruined by a heavy impact, worse than before. Her tits even bounced a couple of small after-shocks as she was bending down again. By the time I recovered from the pain and stretch of the jump, she launched off again.

Then again, and again. It was a different level of pain than the slow jog, but just as bad. More spread out, but harder impacts. I was also becoming aware of that familiar, salty taste starting to build up as Molly worked up a sweat. The squat-jumps continued, sending her tits bouncing painfully inside of me.

“Now let’s move into a slow jog, get those knees up and slap them!” Andrea announced, demonstrating the move by popping one knee up until her leg was straight out from her hips, her opposite hand meeting her knee in a slapping sound. Then she sort of hopped on the other foot, switching her stance to the other leg and hand.

As Molly copied the movement, I was again shocked repeatedly, her heavy chest slamming me again and again, though this time without the weightless feeling between. I could barely keep up with what was happening, the constant movement, constant stretching and constant shocks going through me and overwhelming my senses.

And every second, the taste and smell of sweat built up more and more, until it was hard to imagine a time when I wasn’t tasting it. I screamed to myself, wishing for some amount of reprieve.

“Alright, let’s leave the legs alone for a bit, switch to ‘press-up and squeeze!’” Andrea finally gave me that break.

Again Molly paused, watching the other girls. They held their arms in the stereotypical ‘muscle pose,’ their biceps straight out from their shoulders, elbows bent at a forty five degree angle toward the ceiling. The first move was to raise their hands up toward the ceiling and back down into position, then to swing them forward as if trying to touch their elbows together. At least they weren’t jumping up and down for once.

Molly’s hands went up, causing her chest to bounce just a little, noticeably but not painfully. But then when she folded her arms forward, she pressed her tits together, forcing me between her arms and chest.

“That’s right, try to touch those elbows. We’re all ladies here, don’t be shy about squeezing your boobs!” Andrea joked. I swear she was looking at me when she said that. “Alright, speed up now!”

Andrea started moving double-fast, everyone else following her pace. Molly bounced and squeezed me as the exercise continued.

“Okay then, quick drink ladies and line up for sprints!” Andrea said, clapping her hands. The women paused to take a swig from their water bottles and then started to line up on one side of the large room.

“Everyone ready?” Andrea looked around, seeing them all nodding in response. She looked down at her watch while she continued. “Okay, quick runs today, down and back, keep it up until I call stop. And… begin!”

Molly took off a dead sprint. I screamed, the pain instant and incredibly intense. Every step sent her giant boobs bouncing frantically, like they were desperately trying to escape their confines. She reached the other side of the room and performed a quick turn, before taking off across the room the other way. I was thrown around in a dizzying flurry of the most intense, painful stretching sensation I had felt to date.

I prayed for this to end, for this unbelievably insane torture to end. Finally, after what felt like ages, Andrea called for them to stop. Standing up and breathing heavily, the women milled around waiting for the next instruction.

The rest of the class wasn’t so bad, but there still was a fair share of stretch and bounce. Finally, it was over and Molly peeled me off in the locker room, handing me back to Andrea, who stuffed me into her duffel bag. I was in there, stewing in my own stench, for what felt like hours before the zipper opened and Andrea pulled me out again. We were back in her room back at home.

“So that was fun, wasn’t it?” Andrea mocked. It was clear that she had showered and was now in a loose t-shirt and short shorts. 

“Can we please just turn him back now?” Lisa asked from her position by the doorway.

“Maybe tomorrow,” Andrea teased. “But for now, I need socks for bed. Now leave me, er, leave US alone, it’s bedtime!”

Lisa begrudgingly left as Andrea pulled out her phone and tapped away. Before I knew it, I was in two parts, wrapped around her feet. This wasn’t a terrible sensation, though it was weird when she wiggled her toes inside of me.

“Goodnight!” Andrea giggled, crawling into bed and burying me under the sheet and blanket. I really hope that she’ll turn me back tomorrow.
