[Sketch] Rainbow Dash's Birthday Surprise (Patreon)

Themes: Willing; Casual; Gifting prey;

Synopsis: Rarity is in her boutique, hard at work on Rainbow Dash's birthday present: A stylish new flight suit! Since Rainbow's birthday is only one week away she needs to focus.

Pinkie Pie walks in and the two ponies start discussing their birthday present ideas. Pinkie casually announces that instead of offering her baked goods like usual, this year she will be 'gifting' Rarity to Rainbow as a special birthday treat. Rarity is a little miffed that she wasn't consulted on this decision beforehand, but since Pinkie already told Rainbow to expect a 'super-duper-awesome-birthday-surprise', it's too late to change anything now. Pinkie apologizes for not thinking about Rarity's feelings and vows to be more considerate with her remaining friends in the future.

Rarity continues her work with renewed determination, knowing that this flight suit would apparently be the last item of clothing she ever makes.. and one week later she finds herself sliding down Rainbow's gullet to slowly melt away in her gurgling belly
