so, it's incest (if i remember right)
if i am not mistaken the uke is the older one (a teacher) and the seme the younger (a student)
what i remember is that the seme always insert "something" in his bro urethra and they get caught (maybe) by a teacher
in the end they had sex in the infirmary and the seme use some tube and put it in his and his bro urethra so that he could "cum" inside his bro
i want to re-read this pervy manga again

edit: i do remember it's one chapter but i'm not sure wether it's one-shot, a manga with collection of stories, or if the rest of the manga is still not fully scanlated
thank you

The second chapter in this one-- Haretara Kimi o Mukae ni Iku
