Absolutely wonderful. MC-kun is very cute, and the slightly dark onee-san is just as cute as him if you ask me (A professional hentai fetishist and degenerate). Elf ears onee-san is also wonderful in her own right, but I personally like her the least. I love Oneshota more than anything, and the "You really love boobs" line always gets me. I am very weak to exposed tummy, a nice, shapely stomach always makes me lose myself for a moment. The one thing I would add to this would be a scene that shows both of the women pregnant and MC-kun living happily with them.
