Omgg yess thank you guys so muchh
The two of them were childhood friends and then the other one distanced himself because he has a fetish of wearing a womans underwear. The uke suddenly got a fever and his sister was out so she couldn't help him so she called the seme and he came to their house to give him a medicine and found out that he's wearing a underwear and plugged the medicine into the uke's butt.
