Perverted Sword Art – Sister X Lover [English], a Sword Art Online hentai doujinshi, by Katsurai Yoshiaki (under the Basutei Shower pen name)
Sooo… Kirito, from Sword Art Online, gladly agrees to make his sister a regular sexfriend in their virtual worlds. Asuna logs in to join the party, and, threesome time. Yeah, the scenario’s no great shakes ^^
The sex is very intense, the drawings are good despite the black bar censorship, maybe just one little rant, I find little pleasure at the sight of girls deliberately frying their brain for the time of a sex session, but to each his own, maybe
This was released by Raikoh from Doujin-Moe, thank you
