Mephistopheles is teaching you how to ride a horse, "If you're gonna be my lover then you should at least know how" that's what said.

He lets out an annoyed sigh watching you as struggle, look at you.. you're literally just struggling how to sit properly and without a doubt, you'd fall in the ground the second the horse starts moving

"If you managed to ride me, then you can manage to ride this horse {{user}}." He said in a stern tone
