After Party...

His friend thought of himself as a player by sneaking away with a hot cosplay girl, but Mr. Hentai Protagonist showed him who is boss and banged TWO hot cosplay girls!

Is this really a harem? It's definitely "group" (which isn't tagged) but I consider a harem to be at least 3 ladies. Am I in the minority?

I really liked this release though. Ritsuko's "kya-kya" was so cute after her kiss.

Did they really have to go with the "Senpai, are you still a virgin" bit? Which then implies the girls aren't virgins, despite the whole thing with them knowing each other for quite a while, along with all the blushing and obvious romantic feelings (at least from Yukari anyway).

Couldn't it have just been a nice "we've all had feelings since long ago, so let's finally have our first times together"? Or if you're gonna go with the girls being non-virgins in a 'semi-osananajimi' story, why not make the guy seem like less of a "loser" and make him a non-virgin too?

Because doing either of those is better than making us (or maybe just me, who knows?) feel like the guy has been semi-cucked right from the start because he stayed a virgin while these girls (Or is it just the one girl, was Yukari the only one he knew back then?) didn't?

Well, that's it! Rant over. Sorry for making you read this virgin's idea on how some hentai should be written.

A pleasant night no doubt, but that gentleman will suffer 2 dead arms in the morning sleeping in that manner.

Whoever started this whole "Two women is still a harem" thing is cancer.

C'mon penis "wakey wakey" doesn't wake up, punches dick to wake it up

Instafave! This is one of my new favorites. This needs a sequel.

Sequel with the other girl...please

Perhaps this is most appropriate thing to state (note: not looking to see whether anyone else stated it):

"You can find me in the club, bottle full of bub
Look, mami, I got the X, if you into takin' drugs
I'm into havin' sex, I ain't into makin' love
So come give me a hug, if you into getting rubbed."

BEST! CLUB!!! EVER!!!!!! ... and seems that Yuuki-senpai "became a man" times 2 (the lucky bastard).

APPROVED!

"I've always thought of you girls as something akin to cute little sisters"? Shouldn't be a problem then, cute little sisters in Hentai is quite normal, really.
"I could never pick just one"? Yes, my friend, that is the correct answer as a Hentai Protagonist. The answer is always both/all of them.
Great ending though. Ah, what a nice friend, letting his buddy use his room.
