I don't think I have heard of this before because Kuroka hasn't gotten to the point of wanting to bed Issei in the story because she is teasing the hell out of him but Koneko I already knew about that but at one point she was the closest of bedding Issei if it wasn't for Rias and Akeno interrupting the bed method to infuse chakra into his lifeforce Rias and Akeno would be crying right now.
