I just remember that thw girls name is ayumi and she is dating the brothers friend who is called yuuto. I think he was a president of the school or something. It was a collection of stories if anyone knows the name of the mangaka thats fine too. PLS HELP
Still wanna know who the top is
...I think Mine is the Top (with possibility of reversal?)
... in http://www.mangago.me/read-manga/snip_snail_dog_tail/mf/d_chapter-7/pg-13/, they seem to have just done it (Mine is not wearing his glasses and they both looked ruffled) and Anjo is on his stomach while Mine was sitting, and Anjo said "Let's change places, I'll mess you up".
Damn, i hope they switch then
chap 1 page 11 http://www.mangago.me/read-manga/snip_snail_dog_tail/mf/v01/c001/pg-11
I think Mine is uke. And regarding chap 7 page 13, i think Anjo is suggesting to change place cause if they stayed there he'd end up fucking Mine many more times, hence mess him up.
In ch1 Anjo got mad at the idea of Mine using his asshole for other people. I still hope they switch tho lol
