I appreciate that this is one of those rare futa doujins where the plot isn't basically "Holy fuck, dicks are AMAZING!" But on the other hand the presence of the dick is a bit baffling as there's no real reason for Rin to have one in the first place. You could do the exact same scene without it, and nobody would realize. So...really, why bother?

I don't hate it, but I'm not going to re-read it. Put me down for a "shrug and walk away" reaction.

It's probably because sex is much more pleasurable and meaningful with a dick.

Are you being sarcastic or are you just plain stupid? "More meaningful"? " More pleasurable"? Shut the fuck up, you sound like you don't know what a clitoris is, neither that there is more to sex than piv sex.
