This was inspired by a very old PM trade with Tk Macintosh about oral sex in this pairing. So yeah it isn't much but it's Something I've had on my mind for months.

Also the second half of the dialogue is lifted from Kurimomo's doujin called Naotobon. A very good short read (It's been fan translated into English) if you are fan of this pairing and like adult material that comes with with it.

Premise: That aftermath of Naoto going down on him for the first time.

Previous Chapter's Premise: After My Christmas Present

And thanks to Zanmat0 for the thoughtful review. Reminds me of something I need to do after posting this.

III:

Naoto panted heavily from their last burst of activity. This was completely impromptu and was actually instigated by the sleuth. She was shocked when she realised the calendar date was edging incredibly close to his departure. So in a flustered rush she invited the leader over to have some of his undivided attention. The last time they met up, Naoto in a garbled mess asked Souji if he looked up adult content of the kind. With his typical cool and calmness he made a simple shrug with the answer.

"Sometimes I guess but not often."

That sparked Naoto's curiosity. She wondered where he was able to learn all the stuff he did. Hell the first time he does things to her she has no idea what he's even doing, all she knows is that it feels good and it works. She's always wanted to do more to satisfy him, or be more active in what they do. So she did a bit of research.

And damn she was overwhelmed.

Positions, activities, toys...

There was so much it made her head spin. Who knew sexual activity was so damn complex?

So she narrowed down her he needs and wants, and took down a few notes and remembered to keep them with her for the next time they meet. One of the biggest things she was intrigued by was oral sex, it something that came up a lot but the thought of it flustered her so easily. Her face being that close to his...

To be fair she remembers the first time she experienced it on herself.

"Souji-kun, what are you doing?" She could feel him kissing down her bare chest. This was definitely new for their activities. She clawed at his shoulders as he descended lower an attempt to bring him back up.

"Just trust me on this..." He whispered. She could sense his concentration. Lightly he pulled her legs apart, and then Naoto instantly figured what was going on.

"N-no Senpai! I-It's dirty there!" She tried to bat him away with hands. She could feel him take a deep breath.

"You smell amazing." He told her breathlessly.

"W-Wha..." She cause caught off guard by the compliment, freezing her in place as she tried to process what was going on.

Her eyes shot wide as she felt his tongue swipe against her clit ever so gently, enough to make her hips spasm at the sensation.

"S-SENPAI!"

Yep, Souji's neighbours definitely heard that one. Her face flushed over in remembrance as she blinked out the memory. Her breathing started to slow as she remembered where she was and what she needed to do. However back to the present...

"Senpai you are such a beast…" The sleuth exclaimed in a whimsical tone.

"Huh?" Souji was thrown off by the comment, unsure to take it as a compliment or not.

"You let out so much; I could barely swallow it all." She huffed trying to get her breath back.

"I need tissues…" Souji quickly reached over for the box and handed it to her.

He rubbed the back of his head sheepishly.

"I'm sorry about that, I'll tone it down next time." Naoto quickly shook her head after clearing whatever made it on her face. For her standards she was surprisingly calm for what just happened. Maybe it's the sexual admiration that the last session generated by her boyfriend's passion.

"No no…" She reached for his leg and stroked it lightly. "I'm just amazed. You have the ferociousness of a shadow when you are so aroused…"

She looked up to him with an expression sat in between cute and sexy, eyes looking at him in wonder.

"Was what I did that good?" She asked innocently.

Souji nodded emphatically.

"Definitely! It was amazing."

She smiled genuinely, pleased that she could bring out the lust like that, but also proud of herself that she did a good job.

"I'm glad."

Souji looked, around noticing the sweaty mess the two were.

"Want to take a bath?"

Naoto nodded but gave him an embarrassed smile.

"Yes but you'll need to carry me, my legs are numb from how good your abilities are." Souji grinned scooping the sleuth up in a bridal carry.

"Come on princess, let's get you cleaned up."

"Gladly…"
