I'm gonna drop random order comments as they pop out of my brain, so sorry if this gets rambly.
<spoilers for v5>
I had a suspicion when he got a name, but I'm glad we got to take in Enzo, he seemed so pathetic it was cute again!
I also really like that Akhbar is not some power hungry evil brother, but Raruk legitimitaly isn't suited to lead and they generally get along very well. (Also, the kissing. The kissing was precious.)
Next on the precious list is Alfred and our boy just.. falling asleep on his lap. I aww-ed, legitimately!
And I think it's fitting that Gray gets to be first among the new husbandos, he earned it with watching over us while we had a nightmare and generally just being there and being helpful without having to be asked. (Second if we count Jack, I guess, though technically who knows if maybe there is someone else as well, so I'm counting without flashbacks for now.) I hope we get to help that mysterious adoptive brother who got corrupted down the line! And while I agree with calling Alfred daddy, including Gray in that made me laugh. Somehow I don't think he'd be offended though. Even if it lumps him together with HIS dad.
You've thought up some genuinely well rounded characters that aren't just hot tropes, but seem to have some actual character growth of their own going on.
Also. The sex scenes were all hot. Spark seemed a bit random and I laughed at the choice to heal him or 'heal' him. Sometimes, dear charas, your pick up lines are so bad, you gotta suffer being misunderstood on purpose. (and then I scrolled back and picked the other choice anyway, of course)
Only point of critique maybe.. the headmaster's sprite seems... squished? in comparison to the others. Maybe it's just the shorter arms? Or the head is too small compared to the massive body? I thought maybe he got squished to make him fit the screen and his proportions went off on accident.
He does seem to be White's type and it's not too bad, but it felt more noticable compared to other's sprites. (And White looked TINY next to him, which is admittedly hot. Though he looks at least short with all of them.)
I was genuinely in awe how much you got done since the last update, all the kudos to you! Apart from the hotness, I think your writing is genuinely funny and the story and lore draw you in as well. Great job! Thank you for your efforts and for sharing them!
