As a healthcare worker, I ignore all my anatomy knowledge cuz I need my bottom cockwarming for hours, I need his cervix penetrated. I need my top still hard after ejaculating so he could fuck more.
technically it all starts when jk asks if he can nurse while he fingers yj.
the first time it’s almost experimental, but he quickly grows addicted to the whole deal. he grows a special liking to close his lips against one of
ace bfs yoonkook and a lot of skin on skin contact. yg lying down on the couch and jk lying on top of him, sneaking under yg's shirt, pressing his cheek against his bf's naked stomach, just feeling him close.
