Of course, Eric didn't mind the rest watching him have fun, rather it was the rest watching his women, or women he was considering to have only his that bothered him.
Whether she knew it or not, the Vezir's daughter was taken under consideration, and the rest could be said to be on trial, depending on how they did through the test their fate would change.
With those thoughts in mind, Eric started enjoying the lower lips of the Vezir's daughter, while two of the remaining four started kissing his thighs and milk factories, and the other two brought their mounds to his face.
He was basically covered in beautiful women that seemed extremely hungry for his special milk, and even more so for his little brother inside of them.
While being attacked from all five at the same time didn't really bother Eric, this would make their feast last longer, and there were a lot of variables that might pop up out of nowhere.
