I think that Issei would be scared to death about Sona because if any lecherous thoughts enter his mind then he will get the same treatment that Grayfia gives Sirzechs because Issei should be thankful that Rias got to him first instead of Sona because Issei wouldn't survive under watch.

The thing about being honor student with lecherous thoughts makes me laugh because it is true because I can imagine that myself for him.
