Jackass! - Sawatte Ii tte Dare ga Itta yo?
Mark me down as a fan of Scarlet Beriko! Best friends wander into murky territory when Masayuki discovers that Kei's legs look good in pantyhose. Their mutual friend Katsumi is in a relationship with the school doctor (lookalike to the tailor in my favorite story by this same author). Scarlet has a way of drawing you into the character's emotions. Her work is wonderfully sensual and moving, and the relationships feel genuine and deep. I laughed out loud and scared the dogs when Katsumi sent a picture of sensei post-sex. Scarlet reverses the genre's stereotypes about who plays what role in the bedroom and I love it. If she ever goes team switch, I'll die.
