Trade Friend

I†˜m pretty sure the teacher gave her back the magazine because he was finished reading it...

So you have two girls that once said they wanted to marry you...And not only did you choose one of them (apparently?), you completely exclude the other girl until she finds out about it herself? Also the correct answer is usually to choose them both, and maybe not invite another guy to make it a group thing.
Also, she says the two of them were boyfriend and girlfriend, but honestly, the way they talk about their group, it's almost as if they're just all sexfriends and nothing more.
Also if she really liked Hiro, I think she would have insisted he go first even with the size difference or whatever, but I guess it all worked out in the end and they all get along really...well.

Karen is hot.

Fantastic art, everyone's design is good, Karen is sexy and Hitomi is super freaking cute. With how into Hiro Hitomi seemed, I'm surprised she agreed to have sex with the other guy for her first time so easily. I do have to wonder if she would've ever joined the group without stumbling across it. Karen said she wouldn't steal her boyfriend, but they've been doing this for a least a while before saying that. Eh, all's well that ends amazingly.

Idk about the swinging tag, this just seems like group sex

What a glorious way to trade in the v-card.

As an artist, Musashimaru gives us a virtuoso performance,
with a splendid display of sexy poses, beautiful bodies, and
excellent facial expressions.

Normally group projects suck, but this one rocked.

I was hoping Hiro-kun would have pick both girls but I guess they enjoy the whole swinging aspect of the group and are getting “along” very well.

I believe the common term to describe this scenario is: "Ah, ... This Is Youth." And just from my P.O.V., it's wise that they're 'using protection' (they might choose to do away with such after they graduate).

Perhaps there will be a sequel in which Hiro may have to one day make the choice between Hitomi and Karen, as at this time, polygamy is illegal in Japan ..... unless as was depicted in a classic work that used to be on FAKKU before it went legit, Hiro as he becomes an adult, "rises to the top of society" and does away with any and all laws forbidding polygamy.

And if ever Musashimaru-sensei produces such a sequel, I trust to be there to *koff-koff* read it.

30 pages of goodness :)

So just sexfriends then? Weird since she called him her boyfriend, oh well. Still hot.
