The characters are cute, their story was funny but a bit silly and slightly boring. And their thing? Whether it’s a raw or a lightsaber, the drawing makes it seem like the author forgot that it should be RAW and not lightsaber, but that's okay. Also, about the older brother? The part where he took the cream used on one of their bodies and then used it on his lips was funny. Well, Vasexxxx really is multi-purpose, hahaha!
Honestly, it's a good manga from the start. But the recent update? wtf happened? LITERALLY 10% story and 90% sex. "You guys had sex many times too like DAMN daddy! let him rest. (ノ｀Д´)ノ彡┻━┻
