Luo Binghe moans shamelessly at the fact that Shen Yuan is holding him down, forcing him to stay where he is and take it. He likely doesn't even mean to—he is so gentle with Luo Binghe usually—so it must be that he is driven mindless with pleasure, and that thought has Luo Binghe's hips grinding down against the bed. He has to concentrate to stay relaxed, and his throat flutters several times involuntarily—his unoccupied hand grasps at Shen Yuan's hip, fingers pressing into the soft skin to ground himself. With his other hand, he rubs his thumb against the base of Shen Yuan's erection and sucks hard.
