"Woah. You were right, Helen! These IVR games are really something else," said a petite woman with shoulder-length brown hair as she took her VR headset off and sat up in bed. IVR, or "Immersive Virtual Reality," has been all the rage since the technology took off. All senses could be simulated, and all one had to do was get an interface chip installed, put a headset on, and lay back somewhere comfortable and safe.
A taller woman with wavy red hair and a feminine bob cut grinned brightly. "You promised to let me customize an avatar for you in 'Midnight Social' if you enjoyed IVR. What do you say? Come on, Macy!" Helen begged. "It's a fun game for couples!"
"Yeah, I suppose." Macy sighed. Midnight Social was mostly for socializing and making friends, and it had an incredibly advanced character creator.
Minutes later, Macy stood in a virtual dressing room, her digitized form still resembling her natural body. "How does this work again?"
"I have the controls in front of me! Since you updated your permissions, I can make your avatar while you see the changes in real time," Helen's disembodied voice cheered.
"Real-time? Wait, wh-- ahh!" Macy yelped as a sudden pressure formed in her chest. She looked down and saw her B-cup tits ballooning in size, stretching the fabric of her tee shirt. Despite being in virtual reality, the throbbing in her nipples felt completely real as they brushed against the cotton. At least digital clothing wasn't at risk of tearing.
"Oh, wow! Did that feel weird?" Helen giggled.
"Y-- Yes! Of course, it felt weird. How big are these going to get?" Macy protested. Her whole body started to tingle when her hips pushed outward, and her waist pulled inward. "Ohhhh..." She moaned and trembled as her ass began to inflate, her lower spine curving to give her an exaggerated curve. "Oh god-- is-- is it supposed to feel like this?" She squeaked as she broke out into a sweat.
"You'll be fine! Just tell me if you want me to stop, okay?"
Macy bit her lip and hesitantly nodded her head. "Y-- Yeah, okay... I m-- moooo!" She moaned suddenly as the top of her head and tailbone tinged. Her vulva had utterly soaked through, her nipples hard as diamonds. Strange, unwanted thoughts flitted through Macy's head.
'Milk. Sex. Eat.'
She knew IVR simulated senses with near-perfect accuracy, but the peculiar mental shifts seemed off. "Ahhh... What-- what are you turning me into?" She huffed, watching with crimson cheeks as her breast ballooned past E cup and continued. Her modest shape had already contorted into an exaggerated hourglass.
She didn't want to admit it, but the changes started to feel good. A torrent of milky, blissful warmth flowed like a gentle river through her. Amidst the customization, a slight, orgasmic burst erupted from her clit and dispersed through her vulva. "Mmm--ooooo... Fuck-- this feels like foreplay..." Then again, Helen had always been a foreplay master throughout their relationship, so maybe this was all planned.
"This is way hotter than I thought it would be," Helen purred. "I can see your tits and ass grow in real-time, and you won't stop making such cute noises."
Before Macy could respond, a tail sprouted from her spine's base, quickly followed by horns forming atop her head. "Ahhh-- what-- what is this?"
"Oh, wow-- yeah... Let's put this here," Helen replied, summoning a body-length mirror for her girlfriend.
Macy stared at her reflection with pure awe. The woman reflected had massive breasts that kept growing. She had a perky, round ass and perfect birthing hips. Her hair and eyes had turned a deep purple, and she could now clearly see her horns. A strange sensation from her rear resulted in her quickly noticing a thin tail with a dark tuft swishing behind her. "Wait!" Her face turned a deep crimson. "You're turning me into a cow girl, aren't you!?" She huffed before uttering another lewd moo as her nipples and pussy ached with sexual need.
Her clothes gradually changed, her top turning into a thick, black strap that served as a halter top; a cute maid apron formed on her lower body while a bell collar enclosed her neck.
The voice in her head grew louder. 'Sex. Milk. Pleasure.'
"You know me well, huh?" Helen chuckled. "You're turning out quite nicely. Gonna pee and come back to finish your avatar," she beamed.
Macy began to inspect herself in the mirror, marveling at these sensations' realism. She cupped her tits and shivered at how swollen and sensitive they felt.
"Macy! Log out right now-- fuck... I don't know how to explain this," Helen suddenly screamed after quickly returning.
Macy's eyes widened in panic. What could have happened? Helen was a very calm person, so her cadence was unsettling. She quickly logged out of the game and started to take her headset off.
"Holy shit-- fuck... How is this possible?" Helen muttered.
Macy heard her partner's bewildered exclamations as she fiddled to free herself from the IVR device. Finally, it safely fell to the bed. "What happened!? Tell me!"
Helen stared at Macy and scanned her whole body before putting a hand over her mouth. "Look at yourself-- oh my god."
Macy raised an eyebrow and peered downward, only to be greeted by a pair of inhumanly large tits covered by a thin, black halter top. Her heart raced as adrenaline surged through her body, her tail frantically flicking about. "W-- What!?" She squealed as she jumped to her feet and sprinted to the mirror. Every step she took caused her hips to sway exaggeratedly, making her nearly lose her balance.
When she saw her reflection, she had no idea how to react. She placed a hand on the mirror and felt utterly shocked when the cow-woman in the mirror mimicked her movement. "What the fuck-- how?" Macy stammered. "I-- mmoooo!" She suddenly moaned, her tits spasming as streams of milk flowed from each nipple.
Helen's expression shifted from confusion to a wide grin. "Well, I'll open a support request. In the meantime, why don't we drain those tits of yours?" She asked innocently. "It can take a week or two for them to respond, though."
Before Macy could respond, a pair of hands pulled her top down from behind and cupped her massive tits.
"Mooooo!" Macy moaned in delight as milk pulsed from her teats and coated the mirror. 'Maybe the slow support times aren't such a big deal,' she mused.
