Milky White Mare
The sound of laughter approached the currently empty apartment, a male and a female voice enjoying each others company. The door opened with a clatter of hooves, the two figures stopping to kiss in the doorway as the larger reached over to turn on the lights.
The illumination revealed the two. The larger, a dark brown stallion named Lex, leant and kissed his smaller companion again before picking her up, cradling her against him as he carried her through the apartment. The smaller, a light brown dappled mare called Dalia, giggled slightly, kissing Lex's neck as he carried her, entering the bedroom and placing her softly on the bed.
Lex leant over Dalia, stroking her mane and gazing lovingly into her eyes. The pair had been together as partners and mates a long time, a strong bond of trust forming between them. No words were needed now; they both knew what this evening would bring. Lex lifted himself off the bed, walking to the doorway, giving a loving glance back to Dalia as he left the room to make his preparations for the night.
Dalia smiled happily to herself standing and slowly stripping herself of her clothes, shaking her long mane and pausing for a moment to look at her own well proportioned body in the long mirror on one wall. Smiling again and returning to the bed, she sat on the edge, leaning back slightly, awaiting Lex's return as something caught her eye on the bedside table.
Dalia leant over and scooped up a small glass vial and examined the glistening liquid inside for a moment. She had been to a stall in the market earlier that day, a stall selling many vials like this one. The owner had said that the potions were magic of all kinds; healing magic, plant magic even... sex magic. Dalia wasn't sure she entirely believed in magic, even though she had seen some unexplainable things in her life, but just for fun had purchased one of the sex magic potions. The stall owner hadn't been very specific about what it would do except it would increase her pleasure and would wear off in one night.
She shrugged slightly to herself and quickly swallowed the contents of the vial, lying back on the bed and wondering what was to come. Only seconds later she found out. A strange burning pressure formed in her stomach and somehow seemed to flow through her body, making her gasp for breath. She cringed as this wave of pain flowed along her limbs and over her head, but almost as suddenly as it began it disappeared, leaving her whole body with as strange tingling sensation, as if her skin had become very sensitive.
Dalia caught her breath and lay still for a moment, almost checking she was still all there. As she lifted one hand with some difficulty into her view, she gasped out loud. She wasn't still all there. Her skin had become translucent, almost feeling like soft thick rubber and her body hollow. She gently pushed thumb and finger together and watched as they both deformed slightly, flattening against each other.
Movement seemed harder like this, although Dalia was partially surprised she could move at all. She pressed her fingers harder together, flattening the tips totally and suddenly experiencing the strangest sensation, that she could feel on her inner walls too, even more sensitive than externally.
Suddenly her ears pricked up to the sound of Lex returning and a sudden panic rose. What would he say? How would he react? She tried to stand, and although her hooves had retained some kind of solid weight, she had barely managed to get upright as the door opened. She fell forward into Lex's arms as he entered the room.
"L-Lex...!" she cried as he gripped her tightly against him, squashing her from slightly across the chest, a look of pure shock and puzzlement came over his face.
"Dal... Dalia? What's..." he stuttered, looking over and through Dalia's form.
"The potion..."
Lex looked down again, seeing how tightly he was holding Dalia, her breasts flattened somewhat against him, and quickly released her from his grip, lying her back down onto the bed, positioning himself by her.
"Doesn't it hurt...?" asked Lex, softly stroking his hand down over Dalia's chest.
"To begin with but now ahh..." Dalia broke off into a moan as Lex's fingers stroked lightly across one nipple "Mhh... it's very sensitive now"
Lex smiled to Dalia's moan, bringing his finger back to the nipple, caressing it lightly.
"Squ... eeze..." panted Dalia. Lex looked at her curiously and pressed her nipple flat between thumb and finger. As the internal walls touched, Dalia felt a burst of pleasure unlike anything she had experienced before, making her writhe and moan loudly. Lex shifted position slightly, just Dalia's moans enough to excite him, releasing the squeeze and repeating, each time eliciting the same response in Dalia.
After a few minutes teasing Dalia, stroking and squeezing her changed body, Lex moved to kneel between Dalia's legs, his long length hard and ready. Looking down at Dalia, she gave a slight nod, ready to experience this feeling too.
Lex pushed forwards slowly, his tip slightly denting Dalia's crotch before her passage opened enough to accept him. They both watched as he began to penetrate, Dalia's tightly bunched walls slowly being parted and stretched to smoothness around Lex's shaft. Gradually he slid further in, the strange feeling of Dalia spreading down his length until his tip reached the end of her passage, wrapped skin tight around him as deep as she could go.
Looking down at Dalia, Lex could see her pleasure just as he could feel his own as he began a slow rhythmic thrusting, taking care to only push as far as her shape would allow, his pre coating her inside.
Dalia moaned with each of Lex's thrusts, this tightness was different from any other she had experienced, the whole of her passage being stimulated with each thrust and becoming even more sensitive and pleasurable as Lex's speed increased.
Lex was already fast approaching his climax; the strange sensation of this... material stroking him was driving him wild. As the peak drew ever nearer Lex's body started to take over, he couldn't control himself. With the final thrust Lex lost control totally, hilting hard into Dalia's soft body.
Lex felt the tight pressure around his tip suddenly released, but was too lost in the sensation of orgasm to hear Dalia's shocked cry, for Lex's last thrust had broken through the thin material at Dalia's deepest and now his heavy spurts of cum splashed into Dalia's back, pooling in her shoulders and buttocks.
Somehow, despite the initial shock sensation of the tear, the feeling of her lovers seed flowing freely into her and over her inside pushed Dalia over the edge into her own orgasm. She cried out again, this time in pleasure at the warm fluid flowing inside her.
As the pulses of Lex's orgasm began to subside, he opened his eyes and realised what he had done. With a gasp he unthinkingly tried to withdraw from Dalia, but with this movement he felt her walls wrapped round him tingle and suddenly he was driven back into the throws of heavy orgasm, the flow of his cum not any less than the first spurt.
Dalia too felt the tingle of her walls, her pleasure increasing immeasurably from this and the renewed flow of Lex's seed spilling into her. Soon the pools in her buttocks and shoulders began to overflow, the warm white fluid trickling down inside her arms and legs, forming new pools, and still Lex's flow was as strong as ever.
Time seemed not to exist to the two lovers, both so deeply lost in orgasm, but gradually they felt Lex's spurts slowing, finally allowing them to recover their senses somewhat.
Dalia felt a wonderful warmth all throughout her body. Leaning up slightly to look down over herself she first caught her lovers shocked expression. Looking down at herself she saw why. Her body seemed fine in shape, not deflated or deformed, but where her body had been transparent before it was now filled entirely with the milky white of cum.
"H-how..." she began, but realised it was a pointless question. This was magic; there was no 'how'.
"I... can't pull out Dalia" Lex whispered nervously "You're... holding me"
Dalia's eyes widened "Don't try... there's a hole..."
"What are we going to do...?"
"Hold me close against you and roll me on top" said Dalia. Lex did so, feeling the strange weight of Dalia's filled form resting on him. "The merchant said this would only last one night... we can wait" she said, looking nervously into his eyes.
"But... what if..."
"Shush..." Dalia leant forward and kissed Lex "Don't worry..."
So with Dalia resting her warm and heavy body on Lex, his length still tightly held by her strange walls, the two slowly drifted into exhausted sleep.
The next morning as Lex began to wake into consciousness, he suddenly realised he could no longer feel Dalia's tight walls around his length. He panicked for a second, but then realised something else he could feel. Dalia had fur again. Giving a gentle sigh of relief, he slowly opened his eyes, but gasped again, waking Dalia.
"What... what happened" she asked, seeing her lovers expression, but almost not wanting to know if it was bad.
"Hold up your hand and see" said Lex.
Bringing her hand into view and then lifting herself and looking over her body again Dalia saw what was different. Her body was fine, but instead of dappled brown her fur was now pure milky white all over. She looked up into her lovers eyes and smiled, giggling slightly with relief. Lex grinned too, hugging Dalia and nuzzling her fur covered neck.
"Now we just have to think of an excuse for this" laughed Lex as they embraced, basking in the relief of the morning and the memory of the night before.
