Thanks
Seme is a college student...a sculpting major (? Not sure what to call that major. But what i know is that he sculpts ). Then he meet the uke in a seminar (not sure what kind of seminar it is). The seme went outside and saw the uke kissing the instructor. He learned he was gay but does not mock him. They both did it...but they are only sex friends or smthn... and the seme started to think more about the uke that he molded the sculpture...which is there are trace of fingertips at the back of a guy whose body structure is like the uke...then there are traces of feathers.
Thats all. Thank you in advance those who can find it ♡
