Spoiler :
I recognized every pic as part of scene in the manga. The one where his hand is underneath her (seems to be fingering her) he's not fingering, that happened in the manga, no fingering, and it was an accident. Not one image there suggests an H scene (well only if you've read the manga) so I'm afraid you guys are getting worked up over nothing. There is no actual cunninglus, that happened in the manga too, once again it's nothing. Maybe not nothing, just really borderline. That's the whole point of Kiss X Sis, it's insanely borderline but never once crosses the border completely (it pokes a toe over it a couple of times, breast flashing) One of the more explicit scenes was where Keita had to carry Riko into the bathroom because she couldn't walk, but for some reason didn't step out when she started peeing, Riko called him out on that and, after some talking, made him "wipe her". Yes with toilet paper, and no not #2, but there was no visible nudity. They never go as far as to make it an H (the anime is no exception, I guarantee it) but it goes within a nanometre of it
