Dazai with a degradation kink... Every insult that Chuuya spews out- saying that he can't please him properly or his dick is too small... just spurs him on even further. A whimper escapes his throat as Chuuya coos at his pathetic self. Dazai thrusts his hips as hard as he can, even switches the angle so Chuuya would stop mocking him. It's laughable and Chuuya ends up taking the reins instead, riding him until they both eventually reach their highs :)
