Boku wa Imouto ni Koi wo Suru
Alternate titles: I Love My Younger Sister
OVA (1 ep) | 2005 | Vega Entertainment
Yori Yuki has loved his twin sister ever since he can remember. While his parents brushed it off as a child’s fantasy, he always knew it was true love; but because it is incest, taboo, a forbidden love, he did his best to eliminate those feelings. 15 years have gone by and his feelings never wavered; in fact, they have grown stronger. He’s watched his sister Iku grow up and become a beautiful woman, and now, he can no longer contain his feelings – Yori confesses. Yet even if Iku reciprocates his feelings, that doesn’t change the fact that they’re brother and sister. Can forbidden love last?
