Sisters Beach

†žI†˜ll tell Mom about this if you don’t let me!“ - The sentence every gib sibling dreads...

MC living the dream getting to bang two beautiful sisters in a threesome. Needs sequel!!!

Sister Sibling rivalry... Gets me "right there"

A double creampie like this is always a treat to see. ^_^

And no, you don't have a say in this, just accept what you've been given. *nods*

Great art, perfect characters, yummy sex... I approve. :)

45 / 50

Hentai is rife with implausible scenarios, but this amusing tale of
sisterly competition is actually quite realistic.  The look of intense
wide-eyed curiosity on Nami's face as she watches her big sister
having sex (page 13, panel 4-5) is priceless.  "Ah!  So that's what
fucking looks like.  Onee-chan seems to be enjoying it.  I want to
feel that good, too.  Will that big thing even fit inside me?"

Both? Both is good

Ah the package deal.

You want ______(desired noun), but you have to take _____ (undesired noun) with the deal.

You know who Nagisa looks like? Tamamo-no-Mae in Fate.

This time around, seems like Nami was strictly "in it" for the sake of competing with 'Onee-chan' ... by the close, it seems she "gave her Approval" to Hino (lucky bastard on BOTH counts) to be with Nagisa.

And I also give this my APPROVAL!

Hinasaki Yo's art is always a treat.

Hot dayum...

Sounds like a great beach. Also, I really like that description! Yes, the answer is always...both of them!
Hinasaki Yo makes great Vanilla releases and this is definitely no exception.
Hmm, that ending though. Well, it seems that after doing it once she seems content with letting her sister have Sensei...But who's to say she won't ask to join in occasionally?
Also, the first thing I thought of when she said "I'll tell mom about this if you don't let me" was 'Oh, so a 4P with mom too, then?'
