Two fingers, even ones as large as Dedue’s, aren’t much trouble for Byleth these days. He takes them easily, beautifully, and Dedue always takes great pleasure in this part of bedding him— has ever since that first time that Byleth instructed him on how to do it. Dedue always remembers his lessons, both in the classroom and the bedroom.

It’s tempting to just warm Byleth up this way, finger him through an orgasm or two until he’s pliant and relaxed. But they had also promised their dear Professor their cocks, and he’s loath to renege on that.

“Will you tell His Majesty how it feels?”

Byleth’s words— if he can manage any— to go along with the sight of Dedue working a third finger into him, spreading him wide and pressing into those sensitive spots inside of him.
