Best friend saw right through your bs girly but kept out of it until the climax. Now that’s a true bro... or at least whatever the female equivalent of a bro is, I guess that’d be a sis I think? Total sis fo’ life, sis. Nah mean sis? (I apologize for this comment)
Somehow I have the feeling that Mayu-chan isn't the only one who (*cough-cough*) "Knows" what Yuka was up to with Yuuji; perhaps out of discretion, the others kept their distance.
That's a great description.
Also, I like how the first thing she says is let's have sex, but in like, code. As in, asking him to 'swim' with her.
That ending though. Well...Yeah, I think it'd be pretty obvious that they had sex.
