Silver Bell's birthday is coming up, and his boyfriend Scootaroll decided to celebrate the occasion by gifting him something very unique. Even though the idea he had was something he and Silver never openly discussed, the pegasus was certain it was something his mate would approve of doing for his special day. Not to mention, Apple Buck's immense knowledge in apothecary work alongside Zicoro gave Scootaroll hope that the idea was not only feasible, but safe enough to surprise Silver with.

Apple Buck (and his fiancè Spike) may have seen their friend's idea to be rather daunting, but would Silver Bell be more accepting of it? And if so, what kind of lewd hijinks would ensue after the unicorn takes that transformative potion?
