It took her a lot of courage, and some tricky workschedule manuvering, but Zipp had finally managed to both get herself a paid day off work, and have that day be on the same day Izzy was free of appointments as well, and had managed to make the fact she was coming to visit her stick into her chaotic mind long enough that she could write it down. All she had to do now was to knock on the door and wait for her to answer, then enter, pick up the so-called "VR Visor" (really, more of a multispectrum scanner) and then start the dances wherever she wanted.

If only it was that easy.

"I know that I've told her I was coming to visit," she said to herself, as she toyed with the oval-shaped brass knocker, moving back and forth in its hinge and making it thud and clank softly against the door "but... I've never told her why I was coming here. Should I have told her before? Or would she like the surprise after all? Is she even into me?"

She stopped to look around. That specific part of Maretime Bay was quiet at that time of day, and the sky overhead was almost oppressive in its clearness, especially for somebody being as secretive as Zipp was being right then.

"Well, I've given her an appointment, and I'm at her house... it would be quite weird to come from half a town a way, reach her house, tell her I'm not supposed to be here, and then leave," she said to herself as she raised the knocker and took a deep breath "here it goes nothing."

She slammed the knocker agaisnt the door as hard as she could three times, to the point of hearing the knock echo. Zipp then straightened herself up and practiced a naturally forced smile she could show off once Izzy got around to answer the door, settling into a specific one soon after, putting in a lot of to keep it up as she waited for Izzy.

And she waited and waited, to the point her face muscles started to feel a bit sore from all the forced smiling, but there was no trace of Izzy in sight, nor a sign of any possible contraption she might've built just for this purpose malfunctioning or getting lost on the way to the door.

She sighed as she knocked again, but a slip of the hoof made her grab and lower the door's handle instead of actually knocking on the door, which ended in the door opening with a loud, screeching creak and made Zipp lose her footing for just enough to pratfall and nearly hit her jaw against the hardwood floor.

She then quickly regained her footing and said a quick "Sorry about that," only to realize that she was talking to nopony in particular, leaving her confused and looking dumbfounded for several seconds around herself like she had gotten lost in an unfamiliar part of the city, until she remembered something.

"Oh. Right, they don't lock their doors in Bridlewood Forest if they are waiting guests," she said as she rapidly dusted herself off with a body shake "At least according to her..."

She scanned the area around her, glancing past the messy kitchen and the two open bathrooms besides, until she saw, past two thin division walls decorated colorfully and eccentrically, the living room, with a ratty old couch full of yellow patches and a coffee table, with a perfect replica of the scanner-visor– thought one with a chassis painted in purple and a blue-ish glass instead of the aquamarine one present on her own model– sitting atop a cardboard box covered in warning stickers and labels smudged into illegibility.

“Oh, good, means I don’t have to try to invite her over to my house if she says yes,” she said, while walking down the alley that lead to Izzy’s bedroom. As she got closer, she could hear a soft moaning and panting sounds coming from behind the door, which made Zipp frown a little, quickly realizing what was going on and what that implied for her plan, turning to the door to leave.

Then, like a flash of lightning, a thought crossed her mind and made her cock quiver.

“The headset’s here. And it definitely can look through doors...”

Zipp tip-toed back to the living room and picked up the scanner, adjusted the strap so that it could fit her head’s shape, and then strapped it on over her face. Still walking as quietly as she could manage, she went back to Izzy’s door, her penis timidly peeking out in anticipation of what her eyes were going to see soon enough and her face stamped with a coy but embarrassed expression. She took a deep breath, then slid the setting up to her favorite one, the wood slowly fading out from her field of vision as everything took a blue and white tinge.

Much to Zipp’s surprise, it was possible for her to see the outline of bedsheets discarded aside and the pile of clothes at the feet of an iron-wrought bed so low, it could’ve been mistaken for a futon, as well as the dresses kept in the small wardrobe, the stash of coins and keys hidden beneath a hollow dolphin statuette on the bedside table, and the cabinet containing small objects of purpose unknown to Zipp. But, most important of all, on top of the bed there was Izzy: splayed on her back and with her tail swishing about past the bed’s edge, she was rubbing her own folds, her bones and semi-transparent muscles moving about to make her shape squirm and twitch. It wasn’t possible to see any juice come out through the visor, but, whether it was the door dampening the powers or it being less powerful by itself, Zipp could definitely see Izzy’s heart beat very quickly in her chest and her lungs working in overtime and– even if motion blurred it– Izzy’s vagina was clearly spasming in the quest for something to hold and get a feeling of that simply wasn’t there, plus the fact her lips’ outline was nowhere near covering her teeth and her throat was another telltale sign that she was having fun.

Zipp’s cock went forward and hardened on its own, not even waiting for its entranced owner to touch herself, something she soon set herself to do anyway. She was only watching, but even then, she could not help but slowly sit down and move a hoof close to her cock, stroking it wordlessly as she kept watching the ongoing spectacle of a masturbating Izzy unknowingly baring everything she had to her, leaving nothing truly unseen or unnoticed, from the bucking hip bones and saying tail bones to the spasming plot muscles and quivering and bitten lips. Zipp’s hoof did not have to do much, just keep stroking her dick like some sort of extremely warm cat and letting her imagination do the rest, from making her nuts pulse to the production of droplets of precum.

She almost found herself orgasming, but, before she could make the next few fateful strokes, she stopped herself, realizing just what she was at risk of missing out on if she let either happen. Without giving more than a passing thought, she got up and knocked hard on the door, ready to claim her prize.

“Ah- I’m here I’m here, gimme a sec!” Izzy squealed in surprise from the other side of the door, jumping up and using the sheets to wipe her snatch up before trotting up to the door. Instinctively, Zipp switched to thermal mode with a flick of her hoof: thus, when Izzy actually opened the door, she could see her as one big pony-shaped mass of red with eyes and a wavy quivering mouth, purple spots from her juicy behind hinting that the hottest part of the body wasn’t quite her blatantly blushing face.

“Hello Izzy! I can see you’ve been having fun while waiting for me,” she said with a smirk while glancing at the dripping mare juices forming a puddle around Izzy’s rear legs, making her look like she was melting, which, given the situation and the heat she was radiationg, she very well could have been.

“Uh- yes! I was having lots of fun,” she said, her legs shaking and trembling as she dorkily smiled, her attempts to not bring attention to her wet snatch making it clear she was still quite horny and not done with her session yet “W-why have you got the visor on right now?”

“Oh, I just found it on the coffee table in the living room and thought it’d be fun to wear when knocking,” she said with forced casualness, her throbbing wanting cock attempting to propel itself into the target on its own, but stopped by the constraints of anatomy “I hope you won’t mind it thought, because it’s basically the focus of t–“

“I don’t mind, that visor’s new and improved, produces less radiation, you see, you can set it on whatever,” she said shakily as she tried to cross her legs, only managing to stain her rump coat and cool it down a little bit according to the visor “but… why’s it important for you coming over?”

She froze up and bit her lip for a few seconds as she quickly rummaged her mind for answers, but in the end she gave up and, pointing her right hoof at her erection, she said triumphantly: “Because I want to fuck you with x-ray vision on!”

There was a long pause as the two ponies stared at each other. Then, Izzy grinned as her rear legs started to shake, and Zipp felt that her throbbing member had started up again, and that her heart was racing just as much as Izzy’s probably was.

“Sure!” she pealed, jumping on the bed and laying on her side and placing a hoof under her chin while curling her lips, this sultry pose highlighting the insane heat her vag was producing in the island of juice-cooled fur she had, and her heated teats in full display “Like what you see? And don’t bother with condoms, I know you very well, and I don’t have ovaries anymore anyway.”

Confused by that outburst but curious about its truthfulness, Zipp’s face contorted in a grimace as she slid the settings down to X-ray again and, once Izzy’s leg bones and surrounding muscles were visible, she slowly but surely visually climbed up, until her eyes were looking right at Izzy’s mildly spasming pussy, her womb and bladder… but, when she tried to follow her tubes, there was nothing at their end. Even then, the sight made herl ook extremely inviting to Zipp.

“Oh! I didn’t believe it...”

“It could do that? Well, can do lots of things, it could see if a mare’s ovulating, but, y’know, doesn’t work for me. But let’s not talk about it, let’s talk you!” she then jumped up: before Zipp could react and do it herself, she was dragged and plopped on the bed. She huffed in surprise at being thrown onto the bed, but before she could recover a little, Izzy hopped onto the bed.

In short order– and with speed that could make a cheetah envious– she gave a big noisy kiss to Zipp’s small balls, making her groan and wince in appreciation; then licked her rock-hard cock from base to shaft and did it again two more times, leaving a warm and slippery natural lube behind and further arousing Zipp; and then she started to circle the tip with her tongue, before briefly inserting her tongue in her dickhole, causing Zipp to go “ah!” and quake and jolt. Then, with little warning, that flurry of sleek bones and toned muscles became much more defined, as Izzy jumped up and landed vagina-first on her dick, becoming much more defined: Zipp could now see her cock going really deep, way pas Izzy’s jade gate and deep into her tunnel of love, her hip bone and faded-out uterus giving really good visuals on just how filling her thick rod was and how its length was just the right one for the size of Izzy’s tender pussy. Thanks to the visor, she could see how every small shift, every small thrust upwards or downwards, every little spasm, every attempt by her to squeeze it, influenced the veryshape of her pleasure tube, how her muscles and the organ and muscle shifted to accommodate accordingly and how the bones, like wordless white servants, helped out in holding up those desirable motions of her curves around, the heart visibly pumping a lot of blood to sustain their union as much as possible. The wet, plopping, sound of Izzy’s snatch riding her cock and of her thick plot hitting the mattress perfectly accompanied the act going on, as did the slight strawberry and cotton candy smell Izzy’s perfume– or perhaps her very own mare juices dripping all over– had that was wafting through the air, while their pleased groans and moans and sighs became fast and frequent, slowly synchronizing as Izzy kept riding the cock Zipp was so generously offering. And not only she could see the vag’s walls squeezing and pushing against her cock, she also definitely could feel her shaft being massaged and squeezed by the very creased and very tight pulsing warm sopping wet walls of Izzy’s pussy, not a single spot unstimulated by it.

After a little bit, Izzy stopped going up and down her meat pole, and instead, with a high-pitched squeal, she crossed her legs and then screamed in absolute bliss: the sudden increase in tightness was just the push Zipp needed, as she shouted in appreciation and, curling up a little in preparation with an electric sensation coursing all through her body– with a feeling of absolute mental concentration on her dick– came copiously into Izzy, the cum visible throught her visor as some sort of generic liquid inflating Izzy’s uterus to the size of a particularily large grapefruit. She almost immediately felt light-headed and thus, as soon as her head touched the pillow, she closed her eyes, dazed and panting, but also quite happy with the results, as she fell asleep for a few brief moments. She was woken up feeling the visor being taken off her head, and the feeling of Izzy caressing her lower abdomen.

“That was quite fun” she said with a small sigh, smiling widely at Zipp as she playfully gave a pat to her dripping and increasingly flaccid cock “It’s been a while since anypony has filled me up like you did just a sec ago, and you were so wanting to do that...”

Zipp huffed and then looked deeply in her eyes, smiling as she looked in contemplative post-orgasm clarity. For her part, Izzy was lightly touching and stroking Zipp’s dick like it was some sort of slimy cat toy, her rear legs stained white and grey by the slight overflow..

All of the sudden, Izzy stopped and crawled up the bed, smiling and looking at Zipp as she forced one of the latter’s hooves towards her somewhat-inflated belly and accompaining her to brush it, something Zipp actually didn’t need to be forced to, as she soon started to stroke that soft and fluffy dark pink fur she had.

“Y’know, I liked that,” she said after a few moments of silence, while pulling a half-hug “To feel this full and… complete, I guess. Can’t have foals at all, but I can def be stuffed by you.”

“Uh… well, thanks and you’re welcome,” she said, pausing for a little bit “Does this mean you’d like to do it again sometime?”

Izzy nodded and said: “Yes, I’d like to do it again, with the visor even! Maybe we could invite our friends over to enjoy it too!”

Zipp smiled happily, as she hugged Izzy tight and gave her a cheek smooch, petting her mane and diving her nose in its, as she reciprocated the gesture, using her magic to pull the blanket over them both.
