Ask Mercedes for advice

There were a lot of good choices, but he realized he should probably be careful. If he just started shifting girls to his harem quickly, that could attract the wrong kind of attention. He couldn't shake the nagging suspicion that Seteth would pick up something was amiss, not to mention he didn't know his last name either. Not to mention he was having trouble picking just one of them.

In either case, he did have someone close at hand to ask for advice. He looked down at Mercedes, who had just finished polishing his dick for use again. "Hey, I've got a bit of a question for you," he said to the naked big sister figure who was still on her knees in front of him.

"Yes, Sylvain?"

"If you could have sex with any girl on campus, which one would you pi-?"

"Byleth."

"You mean the new professor?" That had surprised Sylvain. He knew he had forgotten to specify students, and he'd had some fun with her earlier, but Mercedes had answered before he'd even finished the question.

"Of course. She seems so comforting to be around, and her figure, ahhh~" She sighed happily, thinking about it.

"All right, noting that for later. I sort of meant among our classmates." He then ran down the list of people he was deciding between.

"Hmm, hard to pick one..."

Sylvain nodded in sympathy. "Could you massage my dick with your breasts while you think about it?"

"Of course!" Mercedes raised her breasts around his dick and began rubbing the shaft in front of her with great skill. "Hmm, well, if I had to pick one to start, I'd probably pick Annie. She's a good friend, and being a bit closer to her sounds great."

"Good to know," Sylvain replied with a grin, his dick already hard.

"But if I had top pick runner ups, they'd be Hilda, Marianne, Dorothea, and Ingrid," Mercedes added, Sylvain giving her a look to clarify. "Well, they all have great figures, and Hilda's really sociable, even if she doesn't like working. I've seen Marianne in the Church, and I feel like she needs to open up a bit more. Dorothea is also a talented singer, and she's almost a big of a flirt as you are." Sylvain grinned at the comment. He knew he wasn't subtle, but there was something reassuring with how Mercedes had casually compared the two of them while massaging his dick. It was almost ready to release again. "And of course Ingrid is very nice with good muscles, but part of me think she's off limits."

"Hmm? Why?" Sylvain cocked an eyebrow even as he was about to release.

"Well, because she might have feelings for you."

"WhaaaAAAAA-!" He exclaimed, a response both surprise and his orgasm, spraying the cum all over Mercedes's face and hair.
