What makes a stallion? Moreso, what makes a good stallionfriend, and how far will a relationship stretch?

Sweetie Belle's new boyfriend is recovering from an intimate and embarrassing accident and is feeling rather self conscious and questioning his masculinity. Sweetie for her part is doing her best to reassure him that it doesn't need to change anything between them. Her less than nice friend Diamond Tiara however thinks differently, and she is very good at getting what she wants.

This story was written as a New Year's Eve gift exchange and is not canon to my other stories.
It does however fit my normal tone and theme. If you are a regular reader, you know what that means, Content Warning: Gelding, Castration, Cuckoldry, Dubious Consent, Very Dubious Consent, Sex and Diamond Tiara being an absolute bitch.
