The other kind of Generosity

Rarity's instincts almost completely took over her mind at this point. Coco let out a surprised gasp, as Rarity bit into her nipples and started sucking on her breasts. At the same time the succubus transformation kicked in once again, completely ripping Rarity's night gown apart, as her wings spread out. A more subtle part of the transformation, yet one Coco was now fully experiencing were the sharp teeth. Coco screamed both in pain and ecstasy.

Rarity smirked as Coco pressed the unicorn's head against the earth pony's breast.

"Yes...nnghn..more...!" the earth pony mare moaned.

Rarity was more than happy to comply. She threw Coco and herself off the chair. Before Coco could recover, Rarity already pressed her mouth on Coco's, her snake like tongue invading Coco's mouth and even going down the throat.

Coco had a hard time breathing, but somehow her gagging reflex wasn't kicking in. She didn't thought much more of it, as Rarity used her claw like fingernails to play with Coco's clit, tickling and scratching it. The Manehatten mare gasped and panted heavily from Rarity's teasing. She knew exactly where the most sensitive spots were on a mare's more private areas.

The demon of course was only starting. Her tail slowly moved up and started playing with the other breast, while Rarity let Coco catch her breath, going back to playing with her breast. The tail moved around the other breast like a real life snake and squeezed it, while the tip moved further up. In the back of her head Coco was impressed with Rarity's multitasking skills. She had a really hard time focusing with Rarity constantly biting her nipple, while playing with her pussy, her tail squeezing the other breast and finally the tail arrived at Coco's mouth.

Still panting and moaning, Coco looked at the tail, seeing a rose colored liquid dropping off the tip. No doubt it was the poison, which Rarity used the first time they had sex together. She had not much time looking at it, since out of reflex she threw her head back, moaning louder than ever, as Rarity put her fingers finally into her pussy, scratching her insides with her fingernails.

In the meantime her tail made its way into Coco's mouth. Said mare didn't even try to resist. Instead she started sucking on the thing, enjoying the taste of the venom: strawberries. Drinking the venom, instead of getting it directly injected into the blood system, it took longer for its effects to take place, but that was Rarity's plan all along.

Pulling her tail, much to the disappointment of her fashionista colleague, Rarity turned around and put herself on top of Coco. Next she started licking Coco's pussy, putting her tongue deep inside of it. The earth pony's moan wouldn't stop at this point, except when she managed to get it together and trying to please Rarity the same way. Even without her superior experience, Rarity's serpentine tongue was simply longer, plus the two pointy endings were perfectly for teasing the soft flesh.

Coco couldn't take it any longer. She came all over Rarity's face, while the latter was barely aroused at all. Never the less, Rarity drank it all up, using her stretchy tongue to get everything from her face. Coco Pommel lay on the ground, slightly relieved that it was over. Still this time the arousal wasn't gone. In fact Rarity's poison was just starting to show its effects.

Said mare turned around once more and was now looking down at the earth pony. "That was...disappointing." she stated in a cold tone. Coco averted her gaze in shame from Rarity. What else did she suspected? Rarity was a succubus and thus had high standards in her sex life. Coco however had just got her third experience and it even was the shortest out of all of them. Rarity probably would send her away, so she could make herself this potion, which would protect her from Coco's feelings. A small tear ran down her cheek, as the worst case scenario played out in her head.

Rarity placed two fingers under her chin and forced Coco to look directly into the glowing eyes of the demon. The succubus was...smirking? She wiped the tear away with her free hand and then squeezed the left breast of the other mare a little.

"It doesn't matter. This was just the warm up after all."

"W-warm up?" Coco repeated. The succubus lidded her eyelids and gave the pony a small kiss on the lips.

"Oh please. I think it is time we stop playing and I show you what it means to be the plaything of a demon."

"P-plaything?!" Coco squeaked, almost perfectly imitating Fluttershy. Rarity giggled, petting Coco on the head. She went down with her hand and pushed one of her fingernails into Coco's breast through the flesh.

"AHHH-MMMPPH!" Coco screamed at the sudden pain, but was almost mute by Rarity putting her tongue once again into her mouth. After the earth pony stopped screaming, Rarity went down to one of her breasts. Coco expected more sucking, but was really surprised, when somehow Rarity managed to put her tongue into the breast, through the nipples.

"AH! MNNMP! AH!" the mare's mind was torn between pleasure and pain. Luckily the poison unleashed its full effects on the body of the pony, numbing the pain away and only leaving the feeling of pleasure.

"Oh...yes..! More!"

The demon was happy to comply with her tail forcefully pushing itself into the other breast, moving quickly up and down. Coco screamed in ecstasy the whole time, eventually feeling a hot liquid coming out of her nipples. Opening her (from pleasure) teary eyes to find that there was milk leaking out of her boobs.

The pony whined, when Rarity stopped playing with her breasts and instead started drinking her milk. Coco desperately wanted to feel the pleasure of her breast getting played with again and tried to stick her own fingers into her free nipple. However Rarity stopped her hand and grinned at the pony underneath her, milk drooling out of her mouth.

"Now, now Coco, did I give you permission to pleasure yourself?" Rarity asked in a sweet tone that still sounded terrifying, yet arousing at the same time. The earth pony was too afraid to give an answer, to which Rarity only shook her head, acting all disappointed. Her grin failed to make the act truthful.

Standing up, the succubus pulled the pony up with her, forced her to turn around and pushed her onto the table. Coco didn't need any experience to know what came next.

*WAMM* "AH!"

Rarity slapped her ass, again and again. The mare wasn't a masochist by a stretch, but yet again the poison did its work, arousing the poor fashion designer once again, which could be seen from her marehood leaking.

"You're such a slut." *WAMM* "Getting aroused from me simply slapping that nice little ass of yours." *WAMM* "Ahh! AIIEE!"

Rarity pulled on Coco's tail and mane, putting her tongue into the ear of the pony. Coco Pommel shivered, leaning back into Rarity's touch. The succubus pulled her tongue out and whispered into the ear: "I want that ass, Coco. I want your body, your soul, your mind! You awoke the demon inside me and now you have to tell the price."

From the corner of her eyes, Coco could see Rarity's horn glowing up. Her focus shifted towards her surroundings, because all of the sudden they weren't in Rarity's kitchen anymore, but somewhere...else. They were in some dark blue space, which seemed to stretch endlessly.

"Where...are we?"

"Oh I wouldn't worry about where we are." Rarity put both of her hands on Coco's shoulders and rubbed gently down her arms. "But rather what IS here."

On cue multiple violet tentacles appeared out of the ground. For a moment Coco Pommel was confused as to what they were supposed to do, until one after another, her legs and arms were restrained by them.

"Wha-? AHH!! OHHH!!" Coco exclaimed, as multiple tentacles went into her anus and pussy, immediately starting their work on the mare. The earth pony bit her lip, if only to prevent herself from accidentally biting her tongue out. Not enough that her two down holes were penetrated, two smaller pairs of tentacles stretched out her nipples and began fucking her tits. Rarity's ears folded back at the high pitch scream, which escaped the poor pony's throat. The succubus snapped her fingers and one of the tentacles appeared next to her. She pointed at Coco's mouth and the tentacle immediately complied, by pushing itself down her throat.

Rarity smiled at the display in front of her and played with her own pussy, enjoying the muffled sounds of moans from her friend or rather lover. Rarity slowly approached the mare, seeing her cumming over and over again. The tentacles themselves pumped the mare full of their sperm, even so much that they started deforming her body. "That's enough." Rarity stopped the tentacles with a firm command, before they went too far and started breaking poor Coco, although it might have been too late already.

The tentacles gently placed Coco Pommel to the ground. Rarity took the pony into her arms and looked down at her face, surprisingly finding the pony smiling up at her with a cum drenched face.

"That...was...amazing..."the fashion pony whispered.

"Coco, dear, are you alright? I...am sorry. I lost control over my instincts and almost broke your mind. We can-"

Rarity was interrupted by the other mare for once taking the initiative and kissing the succubus, who got a taste of the cum the tentacles put into the earth pony.

"Don't be mistress. I...never felt so alive. If this is how our relationship is going to be, then I'll be gladly your fucktoy mistress."

"Don't." Rarity shook her head. "That was just me overwhelmed by my demon instincts. Let's get you cleaned up."

"B-but Rarity, mistress!" Coco exclaimed. "I...haven't had the chance to properly please you. I...I know I'm not very good at it, but..."

"Oh dear." Rarity stroked through Coco's hair. "I must have given you a too high of a doses of both my pheromones and venom." Rarity really tried to keep herself in line, but she couldn't help but be excited that she still will get to be pleasured. "You really want it?"

Coco nodded. "I do mistress."

"You silly pony." Rarity's hands trailed down towards her pussy. Just barely above, she stopped and cast another spell. Coco watched with wide eyes, as a cock started to grow out of her pussy, fully erected and pre-cum already dripping out of it.

Rarity pinned the other mare down and positioned herself. Without wasting anymore time she stuck her cock in, causing both of them to moan.

"Ah...Rarity..."

"Shut up and let me fuck you." The demon growled, before she started moving. For once both mares experienced the pleasure together. Rarity quickly increased the pace, she herself being impatient, for most of the time it was Coco who experienced the pleasure. Still not satisfied, Rarity used her magic to summon the tentacles again and letting them fuck every one of her open holes. Some of the tentacles appeared next to Coco, but they didn't do anything, since they haven't received any orders from their mistress. Lucky for them Coco took care of that.

"Ah! Come...NNGH...here!" she grabbed some of the tentacles and lead them into her mouth. The rest did basically the same as before. Rarity thrust, the tentacles thrust and Coco just received. The pace increased and increased, until Rarity pulled the tentacle out of her mouth. "Oh Celestia here it comes!"

Once again Rarity increased the pace, causing *SMACK*, *SMACK*, *SMACK*, the sounds of Rarity's and Coco's body colliding to echo all over again until Rarity and the tentacles finally released their cum into Coco Pommel and Rarity herself.

Panting heavily, Rarity released the illusion and both mares were back in her kitchen, their coats drenched with cum.
