A bit of relaxation and learning!

"Mmm, that was so nice, Master..." Dorothea winked after a few moments of catching her breath after their intense sex.

"I'm glad you enjoyed it," Byleth nodded as Dorothea rested her head against his chest. If she hadn't been basking in the afterglow of orgasm, she might have noticed his lack of a heartbeat.

After another moment, she turned to see Sothis and Manuela continue to dance before them. "So... What now?" she asked him.

"You two can stop for now," he told Sothis and Manuela, the former pouting, before settling for kneeling in front of him, wanting to continue being alluring for him.

"So... You said you wanted to touch up on Faith magic?" Manuela probed Dorothea for confirmation, and Dorothea nodded.

"Yes, I would like to aim for becoming a Gremory, assuming I complete my education here," she replied. "I've got a decent handle on Reason, but I have difficulty with Faith."

"Well then, let's get started," Byleth said with a soft smirk as he straightened up and Dorothea got off of him.

"Oh! Oh! Master!" Sothis chirped eagerly from her kneeling position. Byleth, having gotten up to look for the textbook on magics, turned to glance at her.

"You have a suggestion to help with the lesson, Sothis?" he asked.

"...not the lesson, per say," Sothis replied with a sultry demeanor. "But... Would it be fine for me to suck you off while you give Dorothea the lesson?" she suggested.
