High School of Domestic x Discipline (R-18?)

I have got to say one of the best psychologically stimulating fanfics of DxD that I have come across in my many wanderings through fanfic sites, totally worth the read .....................SPOILERS BELOW THIS LINE................... Probably one of the only things I have to take a star away for is the Akeno s*x part, not her giving it up, but that as careful, calculating and emotionally tender as Issei is throughout the story he doesn't do a break check at that moment because they talked about her V-Card being a precious gift to give to someone special and not something to be unappreciated . Akeno just kinda strips and then Issei starts edging her until she wants him to stop teasing her and then s*x happens. Where was the tender dialogue acknowledging that Akeno chooses to give it up to Issei, that he is her special choice? Other than that minor point, full marks and totally worthy of your time and attention
