Yagi to Ookami no Hatsujou Jijou
It was very good love the couple, especially seme......I cried when seeing how seme controlled himself for uke's sake....love it a lotttt....and the last chap in which the uke put seme's dick without preparing and thought that the pain was nothing compared to the urge seme controlled was one of the best....love it....kinda shipped their teacher and their frnd.... especially when their frnd was wondering if the teacher was bottom or top(the teacher was reading BL for research purpose...he is an alien...the characters were a lot similar to the main couple....and then at that time to submit something the main couple's frnd went to the teacher and saw that the teacher was reading BL)....it would have been awesome....like a forbidden love...
