'She usually doesn't take this long to get home...' You had been thinking to yourself for the past half an hour. Just before you go to your phone to text, you hear the front door unlock.

Your girlfriend steps through the door, clearly on edge. "S-sorry I'm late."

"I was actually just about to text you. Is something wrong?" You ask.

"Well, um..." She shuffles towards you, head held low. "It's a bit embarrassing. The company was running some clinical tests for a new product. A new extra-strength lotion. They were ready to run the first human tests, and I was the first to volunteer. Don't freak out, but I think there were some side effects."

"Are you hurt? Is there any irritation?"

"No, no it's not like that." She looks around awkwardly. "On the bright side, there was some pretty generous financial compensation."

"Wait, whoa, hold on. How bad is it?!?" You flinch.

"Don't freak out, please. Again, I'm not in any pain, it's just embarrassing. Promise you won't laugh?"

You ease out a sigh. "I promise."

Your girlfriend reaches down and begins undoing the laces on her boots. "I figured it would be best to apply the lotion to my feet, since they were getting pretty dry, but... well, you see..." She slides the boot off, revealing where her foot was is now a stump with a sock.

"Babe, your leg!"

"Wait, please. It's not as bad as it looks. Well, it is, but it isn't." She slides the other boot off, revealing an identical socked stump on the other leg. You hold your breath in concerned anticipation. She begins sliding her socks off. As you suspected, in the place of her feet were stumps, though with what appeared to be a seam going up both sides of her legs, disappearing into her pants.

"I'm sorry this happened, babe. I-"

"Just a second, please." She interrupts before unzipping her jacket. She takes a deep breath before removing it. What you see before your eyes appear to be 10 large yet flat toes peeping out of the top of her pants, flopped down over the perimeter of her beltline.

It takes you a moment to fully digest what you're looking at. "Is that a new... belt?"

She lets out her held breath at the surprise of your statement. "No, it's um... It's my toes."

"Your... wait what?"

"Let me just show you." She begins undoing her pants and slides them down her legs. The giant toes droop down as they slide. She takes a step out of each pant leg one at a time, revealing what you assumed to be stumps to actually be merely the start of her feet. They're massive but flat as a pancake, having been sandwiched within her pants and hung over her belt. They drop to the floor with loud flops.

You can only stammer, speechless.

She shuffles towards you and puts her hands on your shoulders. "It's okay, babe. We can live with this."

"I... just... I don't know what I'm supposed to think. I mean those are... I mean those are fake, right? No? This is a prank?"

"Babe, you know I don't like pranks."

You hold your temple and mumble to yourself. Your girlfriend begins straightening her massive flat feet out across the floor. After a few seconds, you snap out of your daze. "Uh, do you want help with that?"

She shrugs. You reluctantly grab a toe and straighten her other foot across the floor until both of them have no visible wrinkles or folds. You notice when moving them that the light hits them kind of like an ear or fingertip, in that they're opaque but still able to let a little bit of light through. The light appears to pass through everywhere equally, as if there are no bones in her feet at all. You look and realize you've grabbed part of a toenail, which is now just as floppy and soft as the surrounding skin. She clears her throat. "So we did some measurements. They're each 10 feet long, 4 feet wide, and... a centimeter thick. I think."

You look at every inch of her recent disfigurement in concerned and confused amazement. Doing some math in your head, you come to the conclusion that her big toe alone must be at least 12 inches wide. "This is surreal."

"Believe me, it feels way more surreal than it looks."

"Wait. Wait, what if we get famous from this? This surely breaks multiple human body records!"

"Babe, sorry, that's not going to happen. The compensation money they gave me is kind of reliant on keeping this little trial accident a secret. If word got out, it could damage the company."

"Oh, right." You slouch, gradually coming to your senses. "Well what should we do?"

"You... hmm... can start by giving these oversized soles a massage. I have had a stressful day, after all."

"You're taking this better than I am, and surprisingly, considering you're the one most affected by it."

"Babe, I've had a few hours to react to this. You're still in your first few minutes. Believe me, I screamed when I saw what it did to them."

"I suppose I didn't think about that." You sit down on the floor and bring her oversize flat sole close. You analyze it to try and figure out how to massage it since it has no solid bones to brace your hands up against.

"Babe, it's not that complicated."

"I know, it's just... I don't know. You know?"

"I know... I think."

You think for a bit, then fold her foot back on itself like a towel so that half of her sole faces upwards, and begin massaging both your hands into the soft flesh, using the floor to brace the other side. "Like this?"

"Oh yeah, that's good." She hums. "Ooh, that's actually really, really good. They're really sensitive, way more sensitive than before, even per inch. Oh this is just...  really nice." Her humming gets louder, slipping to a slight moan, which she catches herself half a second into. "Mph, babe. I can't say for sure but I think I might be into this."

"Oh? Should I stop?"

"Mmm, no, keep going. Press harder."

You press your massaging deeper into the flesh, pressing hard enough to form large rippling wrinkles across her sole. "Is this okay?"

"Mmm, oh yeah, perfect. Do you mind if I help myself here? It's putting me in a mood."

"I suppose you should enjoy yourself. You've had a rough day."

"Cool." She slides her right hand down into her undergarments and begins to play with herself. She lays down onto her back and cracks a large smile as she rolls her eyes closed. She begins to lick her lips. She brings the other foot to her and begins massaging it with her left hand, with a bit more force than you, so you increase your force to match hers. She scoots over and lays her head on the oversized blanket of a sole, before wadding it up closer to her head, turning it into a makeshift pillow.

She rolls her head around the flesh pile before bringing the sole to her lips and planting a kiss on it, taking you by surprise. Nonetheless, you continue massaging, gradually increasing your force. Her vocalizations are unrestrained, and soon, she moves from kisses, to licking the sole fairly energetically. This is more stunning to you than the kissing, causing you to pause for a second. You feel her glare at you and immediately get back to work massaging.

Rather than getting back to licking, she lifts her head to speak. "Babe, babe. You know... Just join in. Find the sexiest looking wrinkle on the bottom of my foot and go to town on it."

You contemplate for a second, but then decide not to disappoint. You undo your pants and wrap a portion of the big flat sole around your private region, stimulating with your hand on the opposing topside of the foot. It's not the usual thing you do with your girlfriend, but it's enough to make you both finish around the same time. Your knees shake and you lean over as to not get the floor messy, using her sole as if it were a disposable towel to wipe the discharge off.

She giggles and sighs in satisfaction. "I was not expecting that to be a side effect. Even without touching myself, that's miles better than anything before. Dude, I actually think I might have been making it worse... well that makes it sound bad in the first place. I'll say, I might have been making it less enjoyable by playing with my fingers in there. It's like my feet are my most sensitive parts now. I could climax from a massage alone! Babe, we can't go back to regular sex from now on."

"Well, if you say so. If this makes you happy, then I'm not going to complain."

She looks over at the wadded up pile you used. "Well, it looks like I'm gonna need to shower now."

"Don't forget me."

"Of course, my favorite massage therapist." She leads you into the shower, and you both work to clean off every inch of yourselves, not to mention every inch of her giant flat feet. She manages to climax twice from the soapy cleaning, once per foot. You both laugh about it as you get ready to go to bed. She tosses the blankets and pillows off, and once the two of you lay in bed, she spreads her giant feet as blankets across the two of you, and use the extra slack to form pillows. The first night was a bit difficult to get used to, but after a few weeks, the warm fleshy pillows and blankets became more welcoming than regular cotton. Not only were they warm, but more importantly, they were a very unique part of the one person you love the most.
