Riddler is quick and enthusiastic about stripping Oswald. He doesn't try to look closely (he wants to, but he knows Oswald won't be comfortable with it) and just moves himself about to get Oswald's pants off so he can wriggle his way between his legs. The soft skin of Oswald's inner thighs feels almost plush; Riddler pets it with his hand before moving to curl his fingers firmly around Oswald's hard flesh again.

Like this, on his knees, sitting back mostly on his heels, he can use his mouth of Oswald's chest, a hand between his legs and the other hand- That can grasp Oswald's own, lacing their fingers and holding firmly.
