Kuromame Pack (Circle)

Pairing: Sebastian x Ciel

It's so rare to find a doujinshi which is hot and smutty enough that you feel like blushing when reading it - but they do exist. 3R-R18 makes it onto my incredibly short list of doujinshi which are SPECTACULAR in terms of artwork and creative positioning. Do make sure you're 18+ though Pairing: Sirius x Remus.
