((A member of the mane six))

Twilight Sparkle

((Ok lets do this!!))
 
Rainbow Dash just had drank her potion which caused her breast to become much larger, usually pegasus have much smaller breast, the flattest chest of the 3 species. She was quite enjoying her large breast at the moment, her friend told her about how it was awesome. She was groping herself and for the first time in her life she was able to suckle on her nipples and its what she was doing. Rainbow Dash was currently in her house high up in the sky alone but it wasn’t a problem for anyone who had wings

Twilight flies up to Rainbow’s house to see how she’s doing with her new enhancements, but is surprised to see her suckling herself
 
Twilight: Rainbow? What are you doing?

Rainbow Dash didn’t knew that Twilight knew about her potion. She was in her bedroom when she saw Twilight just entering like she was in her own house
 
Gaaah!!! Hey!! Knock next time!!
 
She said quickly hiding herself under her blankets. She was really surprised to see Twilight there, inviting herself in her house

Oh! Sorry! I just wanted to check up on you! And see how you were doing.
 
Twilight blushes as she was able to sneak a peak at Rainbow’s new attachments

Rainbow Dash was in her bed hiding a bit embarrassed
 
Well I’m doing fine… I was busy actually… hum… I was gonna read
 
She said searching around on the other side of her bed opposite to Twilight so she couldn’t see her much. She got off the bed and stayed down to the floor and started searching, her breast were hanging down and rubbing against the floor which kinda pleasured her, having a cloud floor tickling your breast is indeed pleasant. She was letting out light and quiet moans as she search for a Daring Do book

Twilight hears the moans, a puzzled look forms on her face
 
Are you OK Rainbow? Do you want me to help you find one of your books?

Rainbow Dash became all red and then said nervously
 
Hum…. No… I can manage…
 
She keep searching and her breast keep sweeping across the floor, giving her nice and gentle sensation in her breast. She moans some more but then just rush back in her bed under the blanket. It was in the middle of the day and she said
 
Well look like i can’t find it!
 
She said with a wide awkward and nervous smile, holding her blanket up a bit so her large new breast doesn’t poke out and show Twilight how large her breast were now

A wide smile shows up on Twilight’s face. She knows what’s going on, and she likes it.
 
Well, guess I’m gonna have to help you find it. It would be very unfortunate if you couldn’t finish reading the last few chapters of one of your favorite books.
 
She blushed even deeper as she got close to Rainbow’s bed

Rainbow Keep the blanket up but over herself to cover up and start scooting away from Twilight
 
What… what are you doing… you don’t need to come to my bed…
 
She was a bit nervous now, she was trying to figure out what Twilight was thinking but somepony as smart as Twilight can’t really be understand by somepony as dumb as herself

She slowly begins to lift up Rainbow’s covers
 
Oh, but I do. Trust me, I AM an “egghead” after all.
 
Now, let’s see if you book is under here. She said slowly

Rainbow Dash hold tight on her blanket and scoot away even more after tugging quickly on her blanket to take it off her hand
 
Hey… s… stop it! Its not in my bed
 
She was really nervous, she didn’t want anyone to know about this. She’s proud of her tomboy image as a strong mare… She can’t let anyone see her like that. Especially since her breast are now larger then any of her friends breast, even Fluttershy
