Still, I point out that Issei probably wouldn't touch her whether she wanted to or not out of respect for Sirzechs. Some guys are loyal enough that the thought of betraying a brother like that is not worth it, especially since Issei is already swimming in puss. That is why I'm saying unless Sirzechs gave him a pass, its probably not happening. What's more, its not like Grayfia is 100% cut off from Sirzechs, its not like he's dead, she can still talk to him. He just can't "please" her as he used to.
