Princess Twilight invites Flicker Feather, a very gifted craftspony to her abode in Ponyville. She has watched him work with leather to create devious devices, perilous predicaments and questionable quandaries deep inside his own specially out-fitted basement.
Spurred by inspiration, she creates her own secret little place and wants Flicker to teach her the particulars to this new gift he has given her.
And her return thank-you 'gift' may just be more than he can stand, both physically and sexually.
