Sheesh! Seven years of having sex once a year - with Snape?!?!? Poor Harry! Poor Severus! I like the ambiguity of Severus's motives, but I guess I find it a little unbelievable that he wouldn't have worked out how to get Harry more interested before. I like Severus as a snake, too, but I feel there is a much longer fic trying to get out here. There's almost too many plot threads fighting with each other. Nice wallsex, though.
