Pinkie pie is yearning for her own customized Pinkie Pie she can play with. She knows the wishing well incident didn't go over so well last time, so she decides to use the magical wishing mirror instead. She says the magic lines, "aaand the prospect of being doubly mared- with big boobies... BIG GIANT BOOBIES!!" Suddenly she's in a room with her very own customized Pinkie Pie that has big inflatable boobies! It really worked! Pinkie Pie is so excited she spazzes out a little, marveling at her big beautiful inflatable Pinkie Pie. She hops on and begins to bounce excitedly. She kisses and licks Pinkie Pie's big boobies and continues to roughly bounce and hump her. She feels up her body as she rides her and gets the idea to grind against Pinkie Pie's big inflatable boobies. After all, they're pretty much like beach balls and we all know how good those feel to hump;) Pinkie Pie gets so turned on from rubbing her pussy against her inflatable boobies. She's shown riding them at different angles. She gets back on top of inflatable Pinkie Pie and humps her until she cums super hard. While catching her breath she says, " If only the other ponies knew how much fun I was having with myself." The scene fades out.
