Cutie

Hirama Hirokazu vanilla is the shit!!
Vanilla paizuri sixty-nining... my goodness.

The couples troupe of mean looking tough guy and his loving girlfriend that really knows he's actually a big softie and is just putting on the tough guy act is just too damn wholesome, I love it!
Page 3, what a great kiss!

(also from last week, the other vanilla chapter named Cutie lol)
-good pick @H-Connoisseur, without a doubt the ultimate version of this troupe features the hard ass, bossy office lady who turns out to actually be a tough as a kitten. E.g. Playing Drunk.

He is just being a tsundere!

That was a very chatty sex scene.

Any more recommendations of "asshole" is soft with the girl he loves?

"Ah! Oh, yeah! Your penis is cute, too."
"That word makes it sound like it's tiny!"
(page 4, panel 2)

Junpei is either referring to the word "cute," or to the word "penis."
If the latter, it means Riko uses a slang term that suggests Junpei
has a diminutive dick, like a little boy.

Can anyone translate the kanji in that panel?

Boy, she loves him. And she knows he feels the same way, it's just for him to say it she hasta pull it out him, sometimes she has to pull out his penis as well lol. Anyways, I'm gonna assume they locked the book club door.

Apt title, heh.

If it's not there already, will recommend the "Tsundere" tag - this time around, for the MC (Junpei-kun), trying to be all tough and manly among other males, yet being a big old softie who just loves to snuggle in the lap of his girlfriend, Riko.

Expressed another way, ..... "Well Isn't That Cute? ... BUT IT'S RIGHT!"
