The comission will be a two panel comic showing Rossweisse and Yasaka from Highschool DxD having sex. Panel one would show Rossweisse fingering and eating out Yasaka, Panel two would show Yasaka giving Rossweisse a rimjob while using a dildo in her vagina. Here's some references:

Her in this position but more so you can see the ass and her looking back but you can kind of still see her boobs
