Riddler moans when Oswald does, applying teeth a little more enthusiastically and hand going tighter, stroking firmly and wanting to feel, to experience, hungry for new sensations and knowledge and right now he needs to know more about Oswald. How he sounds when he finds release, how his body reacts, how his mouth tastes afterwards.

His tongue drags next, over the skin he bit. His thumb rubs firmly at the frenulum, his body rolling with the sheer want he feels.
