Some interesting potion[NSFW]

Twilight moan in pleasure as Rainbow Dash was groping her breast, she was a bit rough but she liked it, the slight pain from the rough grope was lovely
 
Thanks to think about me, Let me get that spell and then we will both have our fun
 
She smile in a kinky way, a spell was coming to her mind now, she revise it some more as she let her grope her breast and moan some more
 
I think i have the spell but don’t stop
 
She said nicely and her horn started to glow. She had the spell prepared. She move her head down and aim Rainbow’s breast then cast the spell. Rainbow’s breast started to be stimulated, like if thousand of ponies were massaging them. Her breast started to produce milk really quick, making her breast grow larger and larger and full of milk. Normally its used on cows to make them milk but she figured if she tone it down it would work on ponies to make their breast larger

Rainbow jumps up and starts bouncing for joy
 
Eeeeeeeee!!! Thanks Twilight!  
Rainbow yelled as she was ecstatic to see her glorious boobs return to her chest  
Now, we can have some REAL fun! She said getting excited as the fun was about to begin

Twilight used her magic on herself too so her breast would produce milk but not take expansion. She look at Rainbow’s large breast and smile diving her head in them, she grab them in her hands and shake them on her head
 
You have really soft breast, I love them
 
She said in a kinky tone and simply suck up her nipple in her mouth, milk squirt out and she simply drink it off her breast

Rainbows face was glowing red and let out a long pleasurable moan. She had never felt so good before
 
Oh my Twilight, why don’t you have some more?
 
She said in the same kinky tone and proceeded to bury Twilight’s face in her large cleavage.
 
Let me taste you.
 
Rainbow slowly sucked on Twilight’s hard right nipple trying to slurp up the sweet milk inside.

slurp mmmmm slurp Delicious, but I expected that from someone as pent up as you, egghead.
 
Rainbow’s face is absolutely drenched in Twilight’s golden nectar and now wants Twilight to suck even harder now  
Bite down on my nipple! Rainbow got a kick by a little pain now and then

Rainbow’s boobs released an orgasmic load of warm, sweet milk  
She sucked harder and felt Twilight’s breast do the same thing  
Satisfied, Rainbow fell on her back, on her bed, and started suckling the milk off her still big and swollen tits, giggling at Twilight at the same time

Rainbow looks at her partner, happy to see that she was filled with as much joy and satisfaction as she was
 
So, what do you wanna do now, you sexy, sexy egghead?
 
Rainbow asked

MMMPPHH MMMPPHH Rainbow exclaimed trying to talk some more, but then decided to just lay there, chew on Twilight’s nipples, and drink the flavorful milk squirting out of there. She gave a thumbs up as she layed there as well

Twilight was a bit submissive when it came sex. She bite her nipple really hard then move her mouth off her breast
 
No talking Rainbow and have more milk
 
She said smiling and moaning from the biting and sucking from her breast. She return to Rainbow’s breast and chew her nipple harder, gritting her teeth on her nipple and pull it out a bit then drink some more as she moan. She grope her breast and squeeze them tight time to time

Rainbow did what she was told, and enjoyed more milk  
Then, let out a muzzled moan of joy as Twilight returned to her breasts

((Try to add more description and reaction from what Twilight do please))

((What do you mean?, can you give me an example?))

((Well just look at my post, i always rp the reaction of what Rainbow does to Twilight. If RD hurt her, then i will rp that she is hurt from what your character did))

((Oh, OK, I think I got it, let me see))
 
Rainbow tried to scream with pleasure as Twilight grinded her teeth on her hard nipple, but she was still being choked up by Twilight’s boob in her mouth. So, she did what felt right, and grabbed her nipple with her 2 fingers and squeezed the hell out of it, getting milk on her had in the process.

((Yes exactly like that thanks ^^))
 
Twilight grunt a bit from the tight squeeze from Rainbow Dash, she did like it though but it did hurt a lot, she felt the milk pouring out really fast, sliding on the inside of her breast. This was giving her orgasm so much it was good. Twilight keep grinding her teeth against Rainbow’s nipple and pulling it out, stretching it far from her until her teeth slip off. All this pleasure was making her horn sparks even more, her milk was really good and she wanted more so she started to suck off her breast again

Rainbow managed to remove her mouth off Twilight’s boob just long enough to yell out
 
OH GOD YES TWILIGHT, JUST LIKE THAT!
 
Rainbow noticed Twilight’s horn flashing and sparkling with pleasure, so, in the heat of the moment, she grabbed a hold of it and began giving it a handjob

((Hum how can she break the spell that prevent her from moving her mouth from her breast? Also you kinda forgot about giving reaction to everything again >.<))

((I don’t know, maybe she’s just that strong?))  
((If it doesn’t make any sense to you, Then get rid of the first sentence, and pretend she mumbled those words, not yell them out.))

((What about rping the reaction to all of what i did? You didn’t keep it up… :/))

((I tried to keep it up, but then I accidentally broke the magic spell in order to react to your actions, I’m trying my best here))

((You can describe the reaction still, don’t need to break the spell, Twilight did multiple things to just take time to give the reaction needed to those… I don’t want to be mean don’t worry but… I don’t enjoy much rps that doesn’t have nice description since rping is all about that))
