With the revelation of the best eroge lead since forever, I had to put my money (and Yuuki's penis) where my mouth was and play Cross Days. Braving through bothersome housemates and the non-existential privacy that you would associate with the living room, I managed to wade through Yuuki, or should I say, Yuu's route.
I only attemped Yuuki's route and no one else (although I did receive a Roka Bad End), so I don't have an actual gist of the whole plot, not to mention my severe lack of moonrune comprehension prowess, but that was never my concern anyway. The objective of this speedrun (yes, I skipped some of the more tl;dr scenes), so to speak, was to get myself, as crossdressed Yuuki, to have MANKOTO fill my non existent uterus to the brim with his manseed.
That said, all I can say for now from what I know and without giving too much away is that the story runs parallel with School Days, and you're experiencing it through the eyes of Yuuki. The love triangle from the original series therefore exists, but you disrupt it by falling for Katsura. However Yuuki realises that the she has only eyes for MANKOTO. On the verge of throwing the towel in, he spots MANKOTO cheating on Katsura with Sekai, and concludes that she is the troublemaker (spot on!). Realising the former isn't a bad person, he makes amends by crossdressing (don't ask). One thing led to another, and Yuuki, now known as Yuu, falls for MANKOTO, although the latter does not realise that Yuuki is male at first. Taisuke manages to find the truth out and blackmails Yuuki with it, turning the latter into his personal sex slave in the process. I think you know where this is heading.
But enough of the general plot, if you're not already playing this, you'd be more interested in how the ero scenes were like, and being the ever obliging person, I'm going to break them down the best I can without actually having to resort to posting smut.
Oh noes, he found out that I like to crossdress so I must fellate another man to keep that secret. I will also enjoy it!
Not gay because balls aren't touching.
ORE WA.....YUU NO KOTO DAISUKI DAKARA*!
I'M GOING TO REPEAT WHAT I SAID SO YOU WON'T NOTICE ME STICKING MY PENIS UP YOUR BUTT
Your sex-texting is small time compared to this:
MANKOTO: Yuu, do yuu really love me?
Yuu: Why do you ask?
MANKOTO: Because you're all over Kotonoha
I kissed a boy and I liked it
The taste of his cherry chapstick
I kissed a boy just to try it
I hope my girlfriend don't mind it
Self explanatory. What you don't know is that they forced Yuu to fellate himself too. Reach and flexibility, yo.
HONTOU NI, ONNA NO KO MITAI DERP DERP
I'M AROUSED BY THE FACT I'M FEMALE, SO - SURPRISE ERECTION
In its essence, Yuuki's route is the craziest case of NTR I've ever come across. Also, pardon the shody work, but if I go on any further I'm going to make another trip to the loo again to expunge my own seeds. Anyway, one important thing that I would really like to highlight - I can safely say that Yuuki's route is by far the best (not merely because he's a trap) one out of the entire franchise, and that's saying a lot, because you see, *MANKOTO genuinely falls in love with Yuuki throughout the latter's route, which pretty much redeems his character for me as he Show ▼
I guess true love really transcends all
