It's always so... cute how gentle he is with her. While not the only one, Byleth has always taken such care with her. Yet, he doesn't forget just how sturdy she is either. It's a difficult balance to strike though he's never seemed to struggle with it.

"Yeehaw," she answers, ears up high and tail giving an excited swish or two. The magic behind it is similar to her own - and probably inspired by his - though she hasn't had much chance to play with it yet. Well, okay- Maybe she has, but she can't deny her inclination is to be fucked rather than fuck.

With a fluid ease and grace, she positions herself high and lines him up with the throbbing heat of her sex. She takes that cock like a champ and slides down on him gradually with a low, shuddering groan. "O-oh," she sighs, ears pulled tight and biting her bottom lip.
