Wow, so much to love here! Akira is gorgeous. I love the tall with regular sized breasts body, especially when drawn this well, and consistently! In all of their together panels, she is clearly significantly taller than him, like the how much farther her head goes along his body during the 69 on pg 13, and how she has to bend her legs when their both standing on pg 18, and when she's big spoon in the bath on page 19.
And other things! Yeah soft lap pillows are cool, but I love Akira's rock hard muscle and six pack abs lap pillow on pg 10. The sequence on pg 12 is so good. The way she grabs his face and squishes his cheeks, the beautiful look of determination and desperation on her face, and her just placing his head on the pillow like so. And lastly the matching onesies! Fantastic work.
The only problem, the only singular problem I have with this otherwise good read is the phrase "one month anniversary" because they're celebrating their first month together with a yearly celebration. It bothers me and I don't know how I feel about that.
Woo! The odd couple-matching master Yanase Kotatsu created another classic. Akira is no nonsense in competition of any sort. That's one lucky dude she has there.
Gal Gadot's Wonder Woman-chiq: Incredibly hot and powerful woman with an attractive partner that she pines for, but easily overpowers when overcome by lust, enters the Hentai Hulk Mode: Heart Pupils and a montage sequence of intense fucking with the 70s television series Hulk transformation sequence soundtrack overlaid.
Spoiler below:
Also, her sneaky antics at the end with the kigurumi set are adorable.
Once More, a "Huge Girl x Small Guy" Combo is fine, too (small guy not necessarily being a "Shota", but that works in other instances).
Senpai may have a bit of work to keep up (physically) with Akira-chan, but all indications are she accepts him as he is right now ... and sometimes that's good enough.
