    I remember this being the first S&M yaoi manga I've ever read ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄ And thought I'll never get enough of this

  4. Mekaku_konoha April 28, 2015 3:10 am

    This was pretty bad. Bad art, terrible plot and the sex scenes weren't that great. :/

    1st story was hot two semes a father and son sharing a uke well that was hot, but sometimes seiji looked left out during the 3some. 2nd story was too random for me and boring wtf was he wearing a dress? 3rd story to many plot holes I would of like to know more of the mother and brothers background, why did the mother abuse the son? And ew y'all are brothers wth , it wasn't my cup of tea. And lastly 4th story it was just cute but meh it was just okay...

  8. soulofalover March 18, 2014 6:57 am

    Loved it!! Am I the only female who sometimes wish was born male (with ALL that it entails ....) ? Being part of the yaoi world just seems .... woooowww ....

    • 2d2la March 18, 2014 7:58 am

      Hell no Hun, you are definitely not the only one! I think about it all the time. I'm pretty sure it has skewed my sexuality lol

    • anonymous March 20, 2014 10:11 pm

      I keep wishing to be Misaki from junjou romantica.

    • Miss. T June 27, 2014 6:14 pm

      You're not alone soldier!
      Sometimes I hope I'm a male, so I can have gay relationship with my boyfriend
      But, when I asked him "Will you still love me even when I became a guy?" and he answer "Hell no! Please, just read Hentai! Yaoi give you mental illness, babe"
      Shit, boyfriend! He will never understand my love for yaoi!!

    • Yaranaika July 2, 2014 2:25 pm

      Me too

    • Ijashana August 3, 2014 7:03 pm

      Welcome to my life I tell everybody I want to be male and there like so your gay I'm Luke no I just want to be a male so I can do things from yaoi and well I just have gender issues.

    • JUNNA September 24, 2014 12:48 pm

      SO...We are basically gays trapped in female bodies.

    • kai September 24, 2014 1:06 pm

      my sentiments exactly! somehow I can't get in touch with my feminine side, and I want to be regarded by men as equals, not as a 'woman' (if you get my drift). But can't say that I'm a tomboy either because no way in hell I'm gonna get attracted to another woman (Yuri is a no no - sorry yuri fans). SO yeah, basically a gay man in woman's body? and pretty sure I'm a seme XD

      er.. nope! i've been thinking that since I stumbled upon yaoi YEARS ago... about 9 years? ._. I'll be a fangirl for life. And all over the internet I portray myself as a male :p *points to name and picture*

      lol ;) i feel the same

    • SMH December 9, 2014 5:18 am

      Really guys? I'm as much of a fangirl as the rest of you, but let's be real. I doubt very very few people would actually want to become a gay guy and everything that it comes with. First of all, I doubt any one of you would want to feel the social stigma in many places that comes with being gay and the issue of discrimination. All of you want to become gay guys just so you can go have hot gay sex with sexy boyfriends?

      Yeah, that's not how reality works. You guys are being a complete disgrace to gay people in real life and bringing shame to all that the LGBTQ+ rights movement stands for. You're not having a "gender crisis". You're just fantasizing.

      Peace, I'm out. SMH

      I want to be a guy too but I'd probably be an uke. In the past I was a tomboy but occasionally I still feel boyish XD

      I'm with all of you!!! I would sell all my "girlbits" to be a guy... no PMS or period, walk around in public topless and of course all the fabulous men to play with!!!

      I actually love being a girl, but I get what you're saying as to experience some of the sexy good times that we read about! Though... It's not hard to pretend to be the neko!

    • iamxrae
      May 21, 2015 7:43 am

      Yeah, I've always thought that it would be cool to turn into a gay guy to enjoy some guy on guy sex, then turn back whenever I wanted to. Weird, I know.

    • Godfreya May 25, 2015 8:11 am

      You just read my mind :3

    • Seollie May 26, 2015 8:19 pm

      me too wishing to be nanao-san from mujihi series cuz damn kuon is fucking a caring chara ε=ε=(ノ≧∇≦)ノ

    • HOLYSHIT June 12, 2015 1:19 pm

      Why you guys want to be an uke when you can be a SEME

    • keikeikei August 16, 2015 5:27 am

      I fantasize about that too! (๑•ㅂ•)و✧

      I think I want to be a SEKE, though, so I can have it either way! I just keep on wanting to feel what guys actually feel when they're about to reach climax, or something.

      I also want to experience 3P/threesome (when I'm not committed, of course; otherwise, I'd be cheating, which I don't intend to do)! I mean, well, a girl has two entrances and can have both filled, but I fancy seeing a threesome with a seke more (or well, sometimes, a double penetration too) than a 2M1F threesome (I don't like 1M2F at all, because I'm selfish, haha!).

      ლ(´ڡ`ლ) There's something about a guy's d*ck that mesmerizes me, and I keep wanting to have something like that to touch even on my own. (You know, most of the time I imagine having it, and I want to exercise my hands that way. LOL)

      But, anyway, that's just my sexual fantasy. Because reality is so much harsher. Being gay has a lot more complications, and I admit I'm not ready for all those. Therefore, I can only fantasize being gay.

      ( ̄へ ̄)

    • Pus prince August 26, 2015 11:46 pm

      lol there's a thing called being trans. Like an actual thing, unless you're all just teenagers talking out of your asses

  9. guess who January 12, 2014 3:27 pm

    it kinda looks tempting to try sm stuff... i like the 1st story better...

    • Sarang June 24, 2014 5:42 am

      XD it really does look tempting... maybe its from all my nose bleeds XD

  10. romanticyaoi January 9, 2014 8:30 pm

      Most yaoi SM is really BD.. for serious SM action try Hoshi no Yakata... WOW !!!

  13. Hehe December 5, 2013 4:01 pm

    Say whatever you want folks.. but i totally into this.. hahahaha... the best one ever!!!

  14. Rinachan November 26, 2013 7:08 am

    to those below me whose comment bad .... only few things i like to say. DO NOT READ YAOI SMUT IF U DONT LIKE IT AND U SEE IT GROSSING U OUT!

    thats why its called yaoi hardcore and added to genre as SMUTTY and ADULT. wonder why they read yaoi if they dont like dicks ? guess better to then is shounen ai if they dont like big dicks and gl

    • Rinachan November 26, 2013 6:12 am

      gah... accident hit the enter >.< oh well ... shinning red cocks LOL

      I know ur horny after reading the whole story :P

    • Ian Somerhalder lover November 26, 2013 6:15 am

      It's funny how they don't bother reading the genre's before reading this yaoi and complain afterwards.... I loved it don't know why people dislike it but I guess they all read soft yaoi.

    • Rinachan November 26, 2013 7:25 pm

      @ Ian Somehalder lover
      guess they need to read and learn. reading the genre it helps alot even tho sometimes the uploader add genres wong tho at least they know wats inside before they read not like commenting stupid words.... its their fault reading this story who is idot that do not read genre.

    • Rose April 6, 2014 4:54 pm

      Rinachan you are totaly right

  15. Hayden November 17, 2013 9:08 am

    Okay, so I've seen complaints about threesomes, incest and even sweat? Um this is yaoi you guys, all three are fairly prominent in the genre. Are you new at this or something?

    • Nami November 18, 2013 3:11 pm

      Finally some intelligence.

    • Rinachan November 26, 2013 6:46 am

      is this ur first time reading 3some and more detailed yaoi manga?

    • Ian Somerhalder lover November 26, 2013 6:20 am

      Agree, either they're new or they read shoujo or soft yaoi, but that's my guess

  16. Maiya-chan October 20, 2013 10:26 pm

    I think that was good! I like the sex scenes(threesome is hot!) and the story wasn't bad. The only thing I didn't like was how the dicks where drawn. They look all red and swollen... ewwww.

    • mika-chan November 16, 2013 3:49 pm

      Oooh~! Scaaary realistic penises! They aren't tiny and glittery~! The uke's are actually packing~! oooh~!

    • mika-chan November 16, 2013 3:48 pm

      That's why it's "Hard Core"!

  17. Anonymous August 14, 2013 1:53 am

    Blahhh bad art bad plot, some threesome are really hot like nosebleed XD but this one is really gross. sorry :(

    • Yuna October 6, 2013 7:19 am

      ohh , shut up .. i know its turn u on !! you are just a bad liar .. xDD :P

    • Rinachan November 26, 2013 6:05 am

      Agree to Yuna *thumbs up*

      deep down it arouse lol ... denial is bad for the heart xD

    • Ian Somerhalder lover November 26, 2013 6:18 am

      Don't worry guys people who complain about yaoi will eventually become one of us cause I remember I was like that.

  18. ChanceReader July 3, 2013 2:42 pm

    For a threesome with incest thrown in, it was..... boring.

  19. Rees June 29, 2013 10:44 pm

    Loved it

They read this manga
