TG/TF CLOPFIC.
After a long week in training, Soarin' wants nothing better than to just sleep. But when long-time marefriend Rainbow Dash brings a potion over for some late night fun, neither of them quite expected what they were getting in to.

VERY little in terms of story. More of a practice in gender transformations and sexual escapades. I did my best to give it a beginning, middle, and end.
