Crescendo

As insufferably prudish as Octavia was, being her girlfriend still had its perks. Vinyl had a private spot reserved to herself, overlooking the stage from one of the priciest seats in the whole theatre. It was nice to have some privacy, it meant she could just let her cock out instead of being forced to confining it in her clothes. And she was sure she'd be doing more than just letting it hang out soon.

Octavia may have been flat as a board and with just about as much sexual energy as a piece of wood too, but that was all about to change. Vinyl had had to borrow some of Octavia's own money to buy the little present she'd given her girlfriend just before the concert, but she was sure she would hear no complaints about it. Bimbofication potions weren't cheap, but she was sure it would be worth the price.

The lights all went off and then lit the stage, the curtains were drawn, and Octavia began her performance. Vinyl watched, licking her lips and stroking her shaft in anticipation, knowing any second things would begin to play out.

The performance started out as normal. The usual, boring, insufferable sequence of notes Vinyl had already heard repeated at nauseam through Octavia's many rehearsals and practice sessions. Thankfully, though, after not a minute of it things began to change. Octavia almost missed a note, and Vinyl could see her instrument was being pushed forward slightly. She slowed her hand and began to give her cock big, long and slow strokes, savouring the moment.

Octavia missed her first note. The size of her bust was swelling, unmistakably so as the more it grew, the faster it continued to expand. Still the mare persevered with her performance, and Vinyl wondered if perhaps it was a consequence of the brain fog the potion was surely putting her under.

That lasted until the next sudden growth spurt. Octavia's cello fell forward, pushed away by her expanding tits, its music replaced by the sound of ripping cloth. Vinyl bit her lips and gripped her shaft tight, while her other hand reached for her breasts and began to tweak her nipples.

Octavia's bra had already snapped, and all that was left covering her nipples were a few tatters of cloth she held there with her hands. But keeping her arms so close to her chest would prove to be a dangerous choice. Another growth spurt made her tits press into her arms, nipples rubbing against her hands, and Octavia fell to her knees, moaning. From her spot, Vinyl could see her eyes going hazy as she began to drool.

The pleasure was too much for the earth pony to bear. As the rest of her dress was torn to shreds by the changes overtaking her body, she began to masturbate there, unable to think about anything else. One hand in her wet cunt, one on her now massive tits. Pumped up lips stuck in a whorish O shape and an inflated ass that ensured she'd never need a pillow to sit on again completed her living fucktoy look.

Gritting her teeth, Vinyl thrust her hips into her hand and came. Down below, the audience erupted in a standing ovation, some acting in much the same way Vinyl was. It was funny how the first real reaction of that kind Octavia had ever gotten in her career came right when she couldn't care about it anymore.

Coming down from her high, Vinyl looked at her bimbofied girlfriend still masturbating herself silly on stage. The transformation had been hot, sure, but the end result could have been better. Now that she knew she could help with it, Vinyl wanted her fucktoy to be the best it could be, and her cock told her tits bigger than her head weren't enough to scratch her itch just yet. Nothing that making Octavia down another potion or three couldn't fix, though.
